Found something on Ubuntuforum that helped me. Apparently my Grub2 boot did indeed contain an issue. Though it could be repaired without additional tools, just by two simple terminal commands as found at:
https://askubuntu.com/questions/1149189/gnu-grub-2-02-boot-loop
1. Check the disk code
sudo fdisk -lu
In my case it resulted (predictably) in sda being the only physical disk.
Apparaat       Begin     Einde  Sectoren Grootte Type
/dev/sda1       2048    206847    204800    100M EFI-systeem
/dev/sda2     206848    239615     32768     16M Microsoft gereserveerd
/dev/sda3     239616 778965559 778725944  371,3G Microsoft basisgegevens

/dev/sda5  780003328 937701375 157698048   75,2G Linux bestandssysteem
2. Apply a recheck (??) on grub:
sudo grub-install --recheck /dev/[hard disk]
For me it resulted in (translated from Dutch terminal, so exact wording may differ in UK/US terminal):
Installing for x86_64-efi-platform.
Installation finished. No errors were reported.
3. Update Grub
sudo update-grub
Sourcing file `/etc/default/grub'
Aanmaken van GRUB-configuratiebestand...
Linux-image gevonden: /boot/vmlinuz-5.4.0-42-generic
Initiële RAM-schijf-image gevonden: /boot/initrd.img-5.4.0-42-generic

Initiële RAM-schijf-image gevonden: /boot/initrd.img-5.3.0-62-generic
Windows Boot Manager gevonden op  /dev/sda1@/EFI/Microsoft/Boot/bootmgfw.efi
voltooid
Now, I can boot both eOS and Win10 nicely from the GRUB menu. Lots easier for other family members too, as I do not want them to enter BIOS ;-)


What are the consequences of using gnome tweak tools on elementary

GNOME Tweak tool is designed for GNOME, a desktop environment that is not shipped with elementary OS. While elementary OS does use some of the same components and thus settings as GNOME, not everything is similar or compatible.

Installing GNOME Tweak Tool pulls in a couple of dependencies from GNOME: gir1.2-gnomedesktop-3.0 and gnome-shell-common. These are pretty small packages and shouldn't have any noticeable effect.

Several settings will have no effect since they are meant for GNOME components. The following settings and some others will have no effect:

Icons on Desktop
Lock Screen background
Any of the "Top Bar" category settings
Workspaces

Some of the settings in GNOME Tweak tool are already exposed in the System Settings app that comes with elementary OS, such as several accessibility settings, advanced keyboard options, startup apps settings and more.

TL;DR It's technically partially usable, but keep in mind that it isn't made for elementary OS. Some stuff doesn't work correctly and some stuff doesn't work at all


You're right, it does look pretty bad.
This appears to be some quirk when using the elementary icon theme with Geary.
It's possible to set the GTK_THEME to the Adwaita icon theme which looks much better.
You can set the theme when running Geary with the following Flatpak command.
flatpak run --env=GTK_THEME=Adwaita org.gnome.Geary

To avoid the hassle of opening Geary from the command-line you can make this setting the default behavior by overriding it.
Use the following command to override this behavior for the Geary Flatpak installed in per-user mode.
flatpak override --user --env=GTK_THEME=Adwaita org.gnome.Geary

To override this setting for a system-wide installation of the Geary Flatpak, use this command.
sudo flatpak override --system --env=GTK_THEME=Adwaita org.gnome.Geary


"Using a special user account for setting the guest preferences is the most convenient way to customize the guest session feature. Please follow these steps:

Add a new user account with the username guest-prefs.

Log in to guest-prefs and change things to what you want your guests encounter at startup.

Open a terminal window and create a symbolic link to the home directory of guest-prefs:

sudo mkdir /etc/guest-session
sudo ln -s /home/guest-prefs /etc/guest-session/skel
Now, when you launch a guest session, it will have the same preferences as you set for guest-prefs.

Notes:

In this tutorial we use the name guest-prefs, but you can give the special purpose user some other username.

You may prefer to hide guest-prefs from the login screen and the system menu. Hopefully that will be easy to accomplish when https://launchpad.net/bugs/857651 has been fixed."

First off, both of those processors are a 2010 vintage, and HEVC is a relatively new format, however it certainly doesn't require a dual core.

Neither are performing better, the graphics on the i3 is a 5 year old integrated chip, whereas the Pentium didn't have integrated, so the dedicated card from around the same time is out performing it, as it should be.

         | Pentium T4500 | Core i3-380M
---------|---------------|--------------
Release  | Q1/2010       | Q3/2010
Cores    | 2             | 2
Threads  | 2             | 4
Speed    | 2.3 GHz       | 2.53 GHz
Graphics | None          | Integrated (667 MHz)

Notably, the Intel Pentium T4500 is listed without a Graphics processor, but with two cores, whereas the Intel Core i3-380M is listed not only as two cores but running four threads. The slowdown is likely the integrated graphics on the i3-380M unit which by today's standards are ancient, and will likely have issues playing most HD video, regardless of format, although that is HEVCs primary use.

The reason the older, slower, and less threads (same amount of cores, 2) Pentium is winning out is because that model doesn't have integrated graphics, and as such will be using a dedicated card.


Use gsettings.

I'm going to specifically answer this for the screenshot shortcuts, but you can change it to work for you.

First, we're going to open terminal list all of the options we can change, but filter out the ones we don't want (or more accurately only show the ones we do).

gsettings list-recursively  | grep screenshot

You will see a list like this (click here to see all the output):

org.gnome.settings-daemon.plugins.media-keys window-screenshot ''
org.gnome.settings-daemon.plugins.media-keys screenshot-clip ''
org.gnome.settings-daemon.plugins.media-keys window-screenshot-clip '<Alt>Print'
org.gnome.settings-daemon.plugins.media-keys area-screenshot-clip ''
org.gnome.settings-daemon.plugins.media-keys screenshot 'Print'
org.gnome.settings-daemon.plugins.media-keys area-screenshot '<Shift><Alt>Print'

Just so you know, -clip means it saves to clipboard, the others are fairly self explanatory.

We want to reset them - to have "window-screenshot" reset. "window-screenshot" has the path org.gnome.settings-daemon.plugins.media-keys.

gsettings has a reset argument (like we use the list-recursively option). That's what we're going to use to get it back to what it was.

So, this is the command:

gsettings reset org.gnome.settings-daemon.plugins.media-keys window-screenshot

and now it is reset. Run the original command again to check, and you'll see an output like this:

org.gnome.settings-daemon.plugins.media-keys window-screenshot '<Alt>Print'

A quick explanation if you don't want to reset screenshot keys. For this one, I'll show media keys.

The key we want to grep for is media or media-keys, and here is a section of the output:

org.gnome.settings-daemon.plugins.media-keys pause 'XF86AudioPause'
org.gnome.settings-daemon.plugins.media-keys active true
org.gnome.settings-daemon.plugins.media-keys area-screenshot '<Shift><Alt>Print'
org.gnome.settings-daemon.plugins.media-keys logout '<Control><Alt>Delete'
org.gnome.settings-daemon.plugins.media-keys screenreader '<Alt><Super>s'
org.gnome.settings-daemon.plugins.media-keys volume-mute 'XF86AudioMute'
org.gnome.settings-daemon.plugins.media-keys volume-up 'XF86AudioRaiseVolume'

then you can simply follow the same instructions above for the new path.


elementary OS doesn't use Git. It uses Bazaar, which is an alternative to Git.

To fetch some part of elementary OS from Launchpad:

Go here: https://launchpad.net/elementary
In your browser, select a project on the right side that you want to fetch (I'm going to use Scratch as an example) and then click on the Code on the top.
You'll see the Bazaar command that you'll need to enter in Terminal to fetch the code. Here's an example:

bzr branch lp:scratch
This command is going to create a subfolder in the current working directory and name it scratch. Once the command is executed, cd into that subfolder and then try to build the code by referring to the file called INSTALL or HACKING that will guide you through the process.


How to solve black screen issue on polychromatic

You need to install GNOME AppIndicator by following the guide here


What you call Fusion Drive in Linux is called, for a long time, Logical Volume Management (LVM)

Watch this video I just found (at least the first 6 minutes)

https://www.youtube.com/watch?v=fadQX2e_PGk

To explain it easily enough... imagine you have three hard drives and you want the system to see them as one, with LVM you do that creating a volume group...that volume group (VG) is that huge "disk" and from that VG you create logical volumes (LV) that can be like creating partitions but in this case is from a logical abstraction VG

In your case the only issue I see is in case the sdcard comes late and that produce errors. But try it maybe it doesn't happen at all


Visual notifications not working with Element app

If I'm not mistaken, this sometimes has to do with how the application presents notifications to the OS. Things like Telegram or Skype for instance, can display badge icons in the Dock or Applications menu similar to the way things like AppCenter can. The glowing dot you're seeing in Ubuntu is part of the AppIndicator/System Tray icon in the panel, but this is not reflective of what you might see in the Dock. Take a look at the Ubuntu Dock, for instance. Does the same app provide you with a matching badge for the app there as well? If not, then it's likely that the application is currently hardcoded with support only for typical system tray implementations.


Minecraft launcher started showing desktop paint buffers

The first solution I found was to make sure the window started off in the top left corner of the screen.  But this quickly failed.  Then someone on reddit offered this solution:
Go to:
$ nano /usr/share/applications/minecraft-launcher.desktop
then edit:
Exec=env GTK_CSD=0 minecraft-launcher

Alternatively, running $ env GTK_CSD=0 minecraft-launcher will also work


Is there a supported hardware list for elementary OS?

This is far from official, and in fact is Arch Linux based but is reasonably comprehensive for many different vendors - shows if there are any compatibility issues with Linux modules etc

Daniel, this has already been answered. Check out this thread:

Is elementary OS good for programming beginners?

I made the switch from macOS to elementary OS a few months back because I am bit tired of Apple's ways (a different rant) and if anything improved my development workflow. I thought I would have to give up some of the niceties of my Macbook Pro and macOS but that hasn't been the case. I am a full-stack web developer using JavaScript front-end and back-end frameworks as well as Ruby on Rails. I run both my Node.js and Rails backend API's in Docker containers and everything works perfectly. Some of the applications I user are Git, Visual Studio Code (code editor), Postman (REST API testing), GIMP, Inkscape, & Figma. I didn't find anything to be difficult to install and configure.

The only thing I can't do is iOS development which I don't do often so I have an older Mac Mini that I do that on.

Good luck and ask questions if you need help!


Sorry I can't help with this, but have you checked out if anything on https://wiki.archlinux.org/index.php/NVIDIA/Troubleshooting may be of help?

On a side note: How well does Pantheon work on F31, I was under the impression it didn't quite work in F31? I love the DE, but eOS has so many goddamn bugs, and the devs seem way more interested in making stuff they can slap a pricetag on, than actually fixing their shitty OS.


files copy and paste absolute file paths

I haven't done any setting, but after last update today the issue disappeared.

Therefore, now copying a file into Files and pasting into terminal/text editor does the right this, e.g. it pastes

/home/user/bla/bla/filename.ext

I wonder where this has been fixed.


Left Align the secondary text on Widgets.Welcome

You might be out of luck here. Granite.Widgets.Welcome does not have an API for that.

Here's an approach that might still work: Granite.Widgets.Welcome is a subclass of Gtk.Bin containing a Gtk.Grid. To get at the label you should first get the grid using Granite.Widgets.Welcome.get_child () and then search for the label inside that grid using Gtk.Grid.get_children () which returns a list of all children. In that list you should find your desired label. To align the text to the left, just set that_label.justify = Gtk.Justification.LEFT.

However, you really should not do this. Granite.Widgets.Welcome is not meant for this purpose. It should contain short headings and everything  that goes further should not be included here.

I would suggest using a Gtk.Dialog with a "Do not show again" tick box  that pops up on startup instead.


Make Scratch stop asking to save a file before closing a file

This bug is already fixed in trunk (the current developement branch of Scratch).
See for more details: https://code.launchpad.net/~vishalrao/scratch/fix-1547327/+merge/317063

The only thing to do for you now is to wait for the new Scratch update to be released.


Multiple keyboard shortcuts for switching workspaces

I continued to search around and found that using xdotools you can switch between workspaces with

xdotool set_desktop --relative -- -1 and xdotool set_desktop --relative 1

So I added those commands as custom keyboard shortcuts and they work like a charm

I have the same adapter (in a Lenovo Legion Y530) and I had to turn aspm off for the wireless adapter.

Create a new r8822be.conf file in /etc/modprobe.d/, with the following contents:

After this, I also had to turn off the laptop, unplug the charger, wait for a few minutes, and turn it back on. No more wireless issues after this.


Brightness Controls not Working with NVIDIA Drivers

I can't change the display brightness via FN-Hotkey either. It work's on the energycontrol-settings.

What's the downside of the nuveau-driver for laptops?

I do have another problem, probably related to the nvidia-driver: https://bugs.launchpad.net/elementaryos/+bug/1628929?comments=all

Now, I want to try the nuveau-driver...

Quick edit: My starting point was the nuveau-driver. So, on nuveau-driver I can't change display brightness via hotkey.
I installed the nvidia driver, and can't change the brightness via hotkey, either. Sad.


The easiest way to fix this is to install GDebi (sudo apt-get install gdebi) and open and install the .deb with GDebi.


mkusb persistent live boot configuration

the configuration file is at:

How I found out where the files are:
By looking for the strings I see in the GRUB menu in the raw data on the USB drive, I found that the configuration files are located in a partition called "usbboot", which is FAT32 (the second partition in your screenshot, which is has a different name in your case, since I had this problem with Ubuntu).

If you have Windows installed then you can just go inside your firmware/bios and set the first boot device to the Windows Boot Manager.

To delete grub you need to mount the /boot partition and delete some files. However I don't think it's worth the trouble.


How can I configure Hot Corners from Terminal?

It can be done via gsettings.

Find the key you need(play around with grep to find the exact key, its easy):

# gsettings list-recursively | grep hotcorner
org.pantheon.desktop.gala.behavior hotcorner-custom-command ''
org.pantheon.desktop.gala.behavior hotcorner-bottomright 'none'
org.pantheon.desktop.gala.behavior hotcorner-topright 'none'
org.pantheon.desktop.gala.behavior hotcorner-bottomleft 'window-overview'
org.pantheon.desktop.gala.behavior hotcorner-topleft 'none'

Next - set it (example below sets top-left corner to open slingshot, the applications menu):

# gsettings set  org.pantheon.desktop.gala.behavior hotcorner-topleft 'open-launcher'


Applications are loading very slow, copy/paste operation not going beyond 10MB/s

There is a lot of things that can cause this problem. Could you give more details like when did this problem first occur?

Did you install a new APP?
Do you have a hard drive or Solid State Drive. If you have an SSD is trim turned on.
Are you Maxed out on RAM? "Can be used when transferring data depending on setup."
Are you transferring Files to External storage or the Same Drive?
If external are you using USB 2.0 or 3.0.
If you have a HDD is it making a slight noise. If so a head can be dragging on a platter and you drive is about to die.

Please give as much detail as you can. We can Figure this out together as a comunity.
It could be as simple as an update or as bad as getting a new hard drive.

Can I install Freya alongside of Windows 7?

How can I install Freya? Whether I need any unused partition to use it on Freya. or it will use the Windows 7 partitions.

Backup Data

Step 1: Getting Prepared:

Install windows first. (Since you already have Windows installed, that’s fine.)
Make Room for  elementary :

Create a seperate partition for elementary. This will save you some time later.

Step 2: Install elementary:

Create a bootable usb.
After completely shutdown your system. Now connect your live usb, start your computer and change BIOS boot order. (Press Delete while booting, the key may be different for you)
Now select "Try elementary"
Now start installing elementary, Go through the installer until you reach an option that asks where (or how) you want to install the elementary. (This is the main step, be careful, simple mistake will wipe windows)

Case 1: If you have "Install elementary along side windows" option, then proceed with that option.

Case 2 : If you don't have the above option, select "something else" option.

See Install elementary OS in dual boot with 'something else' option

  Will it slow down if I install both OS together ?

Probably not. It mainy depends on your RAM and your work. Create swap partition.

  Both should not Conflict with Partitions. In future I will any one OS. Can I do it without crash problems?

Create other partitions in ntfs format so that it can be recogniged by both elementary and freya. Also install elementary in extended partition.


How does one run Vim from a new install?

Steps to resolve this issue:

ignore AppCenter. Install vim-gnome from the command line.
install "Menu Editor" from the AppCenter. The Menu Editor icon will show up Slingshot (the "Applications" menu).
Fire up the Menu Editor and select GVim.
Enable the "Hide from menus" switch. Exit the Menu Editor and Save changes.
Fire up Menu Editor again. Select GVim again, and this time deselect the "Hide from menus" switch.
Exit Menu Editor, saving changes.

GVim now appears in the Applications folder.

How to add git branch name to prompt string

I'd suggest something like this add function like you are doing (yours didn't work for me didn't have time to debug):

function parse_git_branch() {
   git branch 2> /dev/null | sed --quiet 's/* \(.*\)/(\1) /p'
}

Then

export PS1=$PS1'$(parse_git_branch)'

If you need to do a more complex substitution then you might need to use sed or similar on the defaut eOS PS1 command, but if you replace it entirely you'll need to maybe look at what it does first, to find out out how to get similar functionality with custom behavior.


This is a known bug: https://github.com/elementary/switchboard-plug-power/issues/89

There's a workaround near the (current) bottom of the page:

  This problem is because the power settings are used from the gconf configuration of the user lightdm, and not the current user.
  Just test:

sudo su
su - -s /bin/bash lightdm
gsettings get org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type

  If you change the settings of the user lightdm, the problem disappears

A little further down, it says you need to set the key to "nothing" (still as the lightdm user):

dbus-launch gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type nothing

You might get a message No protocol specified, which you can ignore.


LibreOffice are moving from Gtk2 to Gtk3, it's not complete yet and buggy. And the toolbar does not use the correct css class that's why.

Pantheon-files: network server not showing after reboot

My current workaround to elementary OS not auto-mounting the webDAV server using Pantheon file browser:

Create root folder on server containing all data.
Bookmark root folder in the file browser.
WebDAV server is automatically connected on first use of the bookmark after reboot.

I am still looking for a better solution. But anyway, this way I work around the issue that I was not able to bookmark the webDAV server itself in Pantheon.


Task Bar Randomly Disappears On Reboot (Resolved)

UPDATE/RESOLVED: This only happens when I choose restart from Windows and choose eOS from the boot manager. Its like the hardware is still in control by Windows. Fresh reboot seems to allow eOS to see the hardware and shows the toolbar. This is my working theory, but I now know how to avoid this issue.


You might want to install the kernel source package from elementary OS, otherwise there is always a risk of a driver problem.

sudo apt-get build-dep linux-image-generic
apt-get source linux-image-generic

You can use another version of the linux kernel, of course.


Less disk space than provided by dual boot

Press there and change it to /dev/sdb

About the other statement you hovering in pantheon-files and seeing less space. You have mixed concepts, remember that in Linux you have mount points acting logically as one but they are separated. What you saw as "File System" is the same amount you see in the root mount point (/). You expected to see it all together but doesn't work that way

Wine opens "Wine application loader" instead of Microsoft Word

If you have problems with starting MS Office with wine (silent crashes, etc.) then you might be missing some libraries (.dll) or you haven't properly installed it (You can install most of them through Winetricks).

To troubleshoot it, try running it through terminal like this:

wine /path/to/office/winword.exe

you should get some error details.

As with icons, similar questions have been answered here and here. To get the icon you want on plank, you need to create a .desktop file and put it in either :

~/.local/share/applications  (your profile only)

or

/usr/share/applications (everyone, requires sudo access !).

Briefly, it should look something like this:

[Desktop Entry]
Name=MS Word
Exec=wine /path/to/office/winword.exe
Icon=/path/to/your/MS\ Word/Icon/icon.png
Type=Application
StartupWMClass=Winword.exe

Also, if you are used to MS Office look and feel, maybe you could give Kingsoft office a try.


It seems like two questions.

For the first one,
try (according to this post) removing the locking file with the command in terminal:

sudo rm /var/lib/dpkg/lock

and then running updates manually with the following:

sudo apt-get update && sudo apt-get upgrade

That will update your repositories information and upgrade all the apps needing an update.

As for the second question,
try the solution, posted here!


Edit: I found a way to solve this that worked for me, so I'm going to post my new information above my previous post.

New information: After hitting the 141 error my screen stuck and I was unable to proceed forward with installation. None of the menu options worked and the only way I was able to restart the elementary installation was by pressing and holding (may 5-10 seconds) the power button.

Then rEFInd booted back up, I selected the thumb drive again and started the install from scratch using instructions from an It's F.O.S.S. guide by Abhishek Prakash (this is for Luna but worked for Freya too): http://itsfoss.com/guide-install-elementary-os-luna/

Previous post: I experienced this issue too installing on an old MacBook Air on a USB drive after setting up rEFInd with OS X El Capitan and partitioning the hard drive in half but leaving it blank prior to booting up Freya.

I am specifically at the Installation type stage of installation. When I click the various options (Quit, Continue anyway, Try again) there is no response and the window appears stuck.

Did you ever figure this out, OP?


Laptop has one bad and one good graphics card

The system should detect the second graphics card, though you may need to disable the first (depending on how it's detected and why it's broken). Not sure which cards you have, but you might need to install a proprietary driver to improve performance after the original install.

You can test the OS without installing by following the install directions, booting from the USB or CD, and following "Try elementary" rather than "Install". It will boot into the OS for you to test without committing anything to hard drive.


Can I get a panel icon (similar to a systray icon) for Deadbeef - like Clementine and many other programs have?

If deadbeef does not appear in the tray in Freya it is because it is not using the Ayatana Indicator API.

For Freya, you can ask for Ayatana Indicator API support, however in Loki this will also not be available. The linked question How can I get applications to display a system tray icon? shows several alternatives for future releases.


No WiFi with Loki and Intel Dual Band AC 3168 card

At the time I am writing, the most current stable kernel is 4.10.8. MSI laptops with Killer Networking are reportedly working on recent Linux kernels. Their support page says so.

Try updating your Linux kernel. Easiest way is probably via Ukuu.

If it helps, I'm running elementaryOS Loki on an MSI Leopard Pro GP62M-7RD and everything works fine after updating the kernel.

Formatting USB stick via GParted - unallocated space?

Assuming that /dev/sdb is your USB stick, just delete the /dev/sdb2 partition then create a single partition from the resulting single unallocated chunk then format it to FAT32 or any format you want.


How can I erase everything when installing elementary OS?

When installing elementary there is a use entire hard drive or erase disk and install elementary os option. This will destroy both your Windows installation and any files you have saved there.


In this particular case, the download was corrupted. Errors can happen during the download process and the larger the file is the more chances it has to be corrupted. This can happen during the download itself or as the file is being written to the drive.
To resolve this, you need to verify your download. The directions to do so are located on the Elementary OS Installation page. This will vary depending on your operating system - and the checksum will change as the distro changes. So, be sure to check there and ensure your downloaded ISO is in fact bit-for-bit correct.
If you want to have your download automatically verified, you can actually use a Torrent client to download the ISO. You do this by clicking on the magnet link in the download window.
For visual reference, this is what it currently looks like:

Files downloaded with a torrent client (using the magnet link) will automatically verify the integrity. The added bonus is that you can keep your torrent client open and help the project by saving the download site(s) some bandwidth.


Elementary OS does not work with NVIDIA (SOLVED)

I solved the problem by downloading the video driver on my windows, I went into ubuntu recovery mode and installed the driver via USB.

No other tutorial worked, because the commands did not work because of dependencies!

Thank you!


How to change the background color of the notifications popup?

Just as the post you linked says you can open the file by entering

sudo scratch-text-editor /usr/share/themes/elementary/gtk-3.0/apps.css

in the terminal. Once it's open look for the section that starts with this

/*******
* Gala *
*******/

The default CSS code looks like this:

.gala-notification {
    border: none;
    border-radius: 4px;
    background-color: transparent;
    background-image:
        linear-gradient(
            to bottom,
            @bg_color,
            @bg_color 80%,
            shade (
                @bg_color,
                0.94
            )
        );

You need to change it to this:

.gala-notification {
    border: none;
    border-radius: 4px;
    background-color: transparent;
    background-image:
        linear-gradient(
            to bottom,
            @bg_color,
            @bg_color 80%,
            shade (
                @bg_color,
                0.94
            )
        );

.gala-notification GtkLabel {
    color: #fff;
 }

Log out then log back in.


What are the download stats for elementary OS?

Almost a year later, I can answer no, these are total downloads for all tracked versions, not just that point release.


elementary Loki 0.4 (64bit), Dual boot: delete one OS and join partition with elementary?

Each partition is containing the whole system? Which one is handling GRUB-boot manager?
Do you have an extra Data-Partition?

If eOS is handling Grub you could just boot up any Live-Image, start GParted or Gnome Disks, delete Mint and increase the size of Loki's partition.

Be sure to make backups before, as data loss can happen when changing partitions.


Is Elementary OS designed for Mac keyboards?

elementary OS uses the command key found on Mac keyboards to represent the superkey (Which is usually represented as the "windows key" on most keyboards.)

So it's fine. You won't have any problems.


Maybe you need to put the theme folder in home/.local/share/themes.
Or maybe that theme doesn't support Pantheon DE.
And i recomend you to use elmentary tweaks for manage your desktop theme and some other things in elementary os.
Sorry for my bad english. Hope this answer help you!


How to share my customized elementary OS with my friends

You could write a bash script containing all the commands that you used to get your OS the way you want it. You could then share that script with friends, and they could run that script on their copy of elementary to get your changes. (If you did things in the GUI, you may need to find command line equivalents of what you did.)

I'd recommend testing this script in a virtual machine with a fresh copy of elementary OS before giving the script to your friends! :)

What you're looking to do is a little like building your own Linux distro. That's probably way overkill for what you want to do here, but if you're interested, this article explains how to get started.


Cannot find VS Code application on Elementary OS

This is more a snap thing than an eOS thing. In other words, I've seen the same behavior on other operating systems where I'd installed snaps.
Here is a thread with a bunch of people who had issues getting snaps to show. In my experience, it generally appears in the menus after a reboot (or logging off and back in again) - so long as it was shipped with a proper .desktop file.
Always? No, probably not always. Frequently? Surely it is, if you plan on installing many snaps. For example, see this particular comment from the above linked thread, where they only see their snaps after they logoff and then login again.


How to get badge notifications on the dock icon for third-party apps?

I'm pretty sure you've linked to the right answer: Plank's badges are separate from notification center, and they have to be implemented separately. However, you might consider adding a wishlist item on the launchpad.

Can not set "Sharing" in Loki final release

I had the same problem but today with an update there came a fix for this.
After the update of the package 'switchboard-plug-sharing' it works.


How to prevent shutdown or reboot when another session is open

I'm not sure if there's a setting in elementaryOS for this specifically, but you can accomplish this by creating a systemd-inhibit startup command that blocks shutdown from happening so long as it's running (as long as the user is logged in). The only downside to this is that if it's running and you want to shutdown from your user, you can't without killing it. I'll explain how.

In the System Settings, click on "Applications" and then the "Startup" tab. Click the small plus sign towards the bottom left and in the custom command entry box at the bottom of the small dialog that's now appeared, enter the following.

systemd-inhibit --what=shutdown --mode=block sleep infinity

Once that's added to the list, log out and log back in. Then try logging into another account and try to shutdown. If all goes well, nothing should happen. You will need to add this to each account you want to keep from being shutdown unfortunately. If you do want to override this, you can run killall sleep in the terminal and then shutdown should function normally from then on.

and install via the command line

sudo dpkg --install ~/Downloads/apt_1.2.15ubuntu0.2_amd64.deb


search in appcenter. GNOME ALSA Mixer. verify that it is not muted. It seems ridiculous, but try it, it worked for me.

please let us know if it works for you.

Can I safely install a bare bone Unity Shell in elementaryOS 0.4?

Installing another desktop environment on elementary OS will probably break things. The elementary apps are designed for GTK+ and Granite, and they may not work properly under Unity. Additionally, I don't believe that Pantheon Greeter provides a way to choose your desktop environment at login. [Edit] I may be wrong about that last part - see the comment below!

See also: this comment on installing the Budgie DE.

If you'd still like to proceed, I'd recommend setting up elementary on a virtual machine and trying to set up Unity there before trying this on your primary OS.

To change the shortcut to (for example) CmdCtrlL run the following in a terminal:

gsettings set org.gnome.settings-daemon.plugins.media-keys screensaver "<Super><Ctrl>l"

Disable screensaver

gsettings set org.gnome.settings-daemon.plugins.media-keys screensaver "[]"

No more accidental locks when trying to hit Chrome's omnibar! ;)

Restore default shortcut

gsettings reset org.gnome.settings-daemon.plugins.media-keys screensaver


You run Gparted and create a swap partition in the disk. Right click on that partition >>information tab.
There you locate UUID and location (ex. /dev/sda5). Then you open '/etc/fstab' (can be opened with Sketch or Sublime) and modify the lines #swap was on <prev dev location> and UUID=<prev UUID> to new data. Save it (you'll need admin password) and reboot your system. To delete previous swap partition boot any OS (not Windows) from USB or from another disk, run Gparted and delete previous swap partition.


How do I stop scrolling from happening when I take my finger off the touchpad?

This is called Kinetic scrolling and it's a toolkit feature. It cannot be disabled.

However you can avoid it by bringing your fingers to a complete stop before you remove them from the trackpad. Kinetic scrolling only happens when you make a flicking gesture.

Activation of WIFI in elementay OS 5 Juno

I am also new but I think I can help you since I had the same problem when I installed elementary for the first time.

Do not you see the wifi symbol anywhere in the upper right corner of the start bar?

If it appears, click on it and you should be able to configure it.

If it does not appear, it happened exactly like ami: you did not install the wifi component when you installed elementary OS. My solution: I uninstalled it and reinstalled it, this time taking care to select the option "add wifi components" during the setup. Maybe there is a better alternative, but from what I tried this I solved the problem.

Good luck!


After some extened research and trials I managed to find a almost perfect fix.

Edit:

/etc/X11/xorg.conf

and add:

 Option      "TearFree" "true"

It will looks like something like this:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod" "sna"
   Option      "TearFree" "true"
EndSection


No, there is no need to remove mesa before installing AMD's driver. And the answer by Suditu George is almost completely incorrect. AMD does provide drivers for 16.04 in the form of AMDGPU-PRO.


Is it true that Elementry OS is quite vulnerable to Mass Surveillance programs like PRISM?

The Amazon shopping component has nothing to do with "PRISM" or other mass surveillance programs (though the amazon component of Ubuntu is hardly something I would call mass surveillance). But anything you do online can be tracked no matter what system you use.

Elementary does not have the Amazon shopping tracking component.


elementary OS: Wingpanel and plank load very slowly at boot

A supposed fix is to run this command:

I too had long boot times. I found this fix and tried it and I have not had issues with boot times since.

What is the Checksum of the elementary OS Loki Beta 2?


Elementary OS 5.0 won‘t install on MacBook Pro 3.1 (Core2Duo)

Welcome to the Elementary OS forum.

I am a fellow Macintosh enthusiast, although I have not run into your specific issue, I did a bit of research and found the following:

Depending on your specific model of MacBook Pro (circa 2007) you might be caught in the trap of the processor is 64-bit, however, the EFI only has a 32-bit, and consequently, only are capable of booting in 32-bit mode.

Which Intel Macs have 64-bit processors? Which have a 64-bit EFI? Which are capable of booting in 64-bit mode?

Matt Gadient wrote a very useful blog post describing the problem and a few different fixes.

Good luck!

UPDATE:
Have you had the chance to try the Boot-Repair Utility?


When I install ubuntu or elementary OS, my laptop (Asus E200HA) keyboard does not work. But it works perfectly fine when I install Lubuntu

I had the issue when I installed Loki 0.4.1. (I was eagerly hoping for the SD  card to be fixed) but I faced the same issue on my Asus E200HA

So reverted back to 0.4.0. this release doesn't have this issue (pressing a button on the on-board keyboard and going to sleep). Maybe this could help you as well?

The only things I didn't get working was the SD card reader and audio. The rest was pretty stable.

Any issue related to the elementary.io website can be reported here: Elementary OS website GitHub. Your particular issue is already reported here, and it seems to be caused by slack links expiring after a certain number of uses. I encourage you to contribute to that issue on github, and maybe ask for a working invite link there.


I'm on the trail.
I think I had ownCloud installed as a snapt.
Now that I have installed the Snapt Store as a Snapt app, ownCloud is displayed as installed there.
Since I don't need the program (rather NextCloud) I uninstalled it there.
However, the three components that need to be updated are still displayed in the AppCenter. :-(


GRUB not showing after installing Elementary OS alongside Windows 10

Since the previous method not solved, this is the possible solution:

Steps:

Boot into windows and open command prompt as administrator, and run the command to disable hibernation

powercfg /h off

Disable Fast Boot,

Control Panel -->
select the Energy Settings-->enable show hidden settings -->uncheck Fast Boot ( this is  the path in older systems)
Now shutdown completely
Now boot from elementary live usb/cd (select Try elementary )
Open terminal and run the commands:

sudo mount [1] /mnt
sudo mount [2] /mnt/boot/efi
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
sudo chroot /mnt
grub-install [3]
update-grub

Note:

[1]=system partition  ; [2]=efi partition; [3]=disk

Use gparted to identify partitions

Finally, Boot into BIOS and change the boot order in UEFI settings.
Select elementary to be the default operating system to boot.

Check if you have broken soft links in /usr/bin:

cd /usr/bin
for x in * .[!.]* ..?*; do if [ -L "$x" ] && ! [ -e "$x" ]; then echo "$x"; fi; done

This will list all broken soft links. If you have any, specially the which command, there's your answer. Just remove the broken link and relink again:

cd /usr/bin
sudo rm which
sudo ln -s /bin/which which

  In my case, I had installed some Node.js packages globally (entries added to /usr/bin), and one of them was replacing the default which command with a Node.js custom one.

  Then, at some point I switched the Node.js --global installations from /usr/local/... to my $HOME (to solve a problem with node-gyp), after which I ended up with plenty of broken links on /usr/bin.

If you want you can remove all broken links (at your own risk) using:

sudo su -
cd /usr/bin
for x in * .[!.]* ..?*; do if [ -L "$x" ] && ! [ -e "$x" ]; then rm "$x"; fi; done


How to revert back to older elementary package?

Use apt-get install «pkg»=«version».

Focusrite Sapphire PRO 14 - Firewire card doesn't work after update

I understand you don't use ffado. Instead, you are using the driver snd_dice that is included by default in the linux kernel (DICE is the chipset used in some Focusrite and Presonus Firewire audio interfaces).
i don't know all the details, but I understand that snd_dice has some severe limitations. If you have made some changes in your interface settings (say under Windows 10), the driver might be struggling to communicate.
Is the interface not visible as a possible output in the sound system preferences?
If not, I would try two things:
1/ reset your interface settings and re-try in elementary
2/ (can be tricky and mess up your system a bit) install ffado and jack sound server. ffado should become the driver for your interface, but you need to blacklist snd_dice as there is a risk of driver conflict...

Thanks, Marc


To install stlink in elementary OS, you will have to build it from source code. Please follow the instructions,
At first please install these required packages for stlink by executing,
sudo apt install build-essential cmake libusb-1.0-dev libgtk-3-dev clang gcc
Then please download stlink and extract it to stlink(you can choose any name, but we will use it in the process.
Go to the stlink folder and execute the following commands,
make release
make debug

The debug target should only be necessary for people who want to modify the sources and run under a debugger. The top level Makefile is just a handy wrapper for:
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Debug ..
make
You could install to a user folder e.g $HOME: cd build/Release; make install DESTDIR=$HOME
Or system wide: cd build/Release; sudo make install
Fixing cannot open shared object file
When installing system-wide (sudo make install) the dynamic library cache needs to be updated with the command ldconfig.
The above information is grabbed from stlink's github repo.


Finally, there is a simple way to fix this: simple change the icon file from webide.png to webide.ico, or using this useful app to edit the menu: https://apps.ubuntu.com/cat/applications/precise/alacarte/

How to change default folder for saving screenshots?

It looks like the screenshot app location and the one of the prt sc button command are different. In order to achieve what you need I can recommend you to use the Files application, navigate to the parrent folder of the one you want to store the screenshots automatically, right click on the folder you want the screenshots to be stored and select Copy as Link. Open the Pictures folder, right click inside, choose Paste Link there and rename the link to Screenshots.


Unicode locale error while running lollypop music player

Try in terminal :

localectl set-locale "LANG=en_IN.utf8"

localectl set-locale "LANGUAGE=en_IN.utf8"

Check again your /etc/default/locale  file matchs the changes. Check Lollypop runs without issues.

Also:

You can manually update your locales specs:

sudo dpkg-reconfigure locales

Notice your language format. It should be "en_IN.utf8" or "en_IN.UTF-8" (*)

Now, edit your enviroment file:

sudo scratch-text-editor /etc/environment

Add a new line with:

LANG="en_IN.UTF-8"
LANGUAGE="en_IN"

Replaced "en_IN.UTF-8" by "en_IN.utf8" according (*).

Save and close the file. Now edit your locale file:

sudo scratch-text-editor /etc/default/locale

Delete all the content and type:

LANG="en_IN.UTF-8"
LANGUAGE="en_IN.UTF-8"
LC_CTYPE="en_IN.UTF-8"
LC_NUMERIC="en_IN.UTF-8"
LC_TIME="en_IN.UTF-8"
LC_COLLATE="en_IN.UTF-8"
LC_MONETARY="en_IN.UTF-8"
LC_MESSAGES="en_IN.UTF-8"
LC_PAPER="en_IN.UTF-8"
LC_NAME="en_IN.UTF-8"
LC_ADDRESS="en_IN.UTF-8"
LC_TELEPHONE="en_IN.UTF-8"
LC_MEASUREMENT="en_IN.UTF-8"
LC_IDENTIFICATION="en_IN.UTF-8"
LC_ALL="en_IN.UTF-8"

Replaced "en_IN.UTF-8" by "en_IN.utf8" according (*). Save and close file.

At last, in terminal:

sudo update-locale

To check that all is well, type in terminal

locale

This command should throw you the same content as we stuck in the last step. If so, reboot and try again with Lollypop.

Taking too much time to boot the system..?

You can disable any service by runinng the command :

sudo systemctl disable Service_name

With this command the service will be disabled at boot. Try disabling the top two services and install a program called preload ( It cuts off boot-up time ) .

For installing it run :

sudo apt-get install preload

To hide the boot messages ( that long list ) : Press ESC or Num 0 when they show up.


To do this in a clean way, you will have to create a custom GNOME session file and a X Server session file (first, install openbox via sudo apt-get install openbox obconf menu of course). Let's take a look at the two files currently present:

/usr/share/xsessions/pantheon.desktop (X Server session file):

[Desktop Entry]
Name=Pantheon
Comment=This session provides elementary experience
Exec=gnome-session --session=pantheon
TryExec=wingpanel
Icon=
Type=Application

/usr/share/gnome-session/sessions/pantheon.session (GNOME session file for Pantheon):

[GNOME Session]
Name=Pantheon
RequiredComponents=gala;gnome-settings-daemon;
FallbackSession=ubuntu
DesktopName=Pantheon

So, to create your own Openbox session, you need to create two new files:

/usr/share/xsessions/pantheon-openbox.desktop

[Desktop Entry]
Name=Pantheon-Openbox
Comment=This session provides a custom Openbox experience
Exec=gnome-session --session=pantheon-openbox
TryExec=wingpanel
Icon=
Type=Application

/usr/share/gnome-session/sessions/pantheon-openbox.session

[GNOME Session]
Name=Pantheon-Openbox
RequiredComponents=openbox;gnome-settings-daemon;
FallbackSession=ubuntu
DesktopName=Pantheon-Openbox

You are now able to select your custom session upon login.

Keep in mind that neither Wingpanel nor the GNOME technology stack is really created for working with such a session - while it might work, you can expect rough edges. I really would not recommend to use it that way, but it's an answer to your question. Use on your own risk, of course. There is no real benefit Openbox is offering over Gala, especially in terms of integration with technologies used by elementary OS.


I decided that it was simpler to reset than continue trying to find a solution. Luckily, I was able to back up my files beforehand.

Mods, feel free to lock this thread if necessary.

How can i enable Canonical Partner in elementary Juno or Is there an application of a similar sort ?

You need to install software-properties-common and software-properties-gtk packages.

Use this command.

sudo apt install software-properties-common software-properties-gtk

After installation is complete, you can just search for 'software and updates' in start menu.

Installing elementary (replacing ubuntu) without having to reinstall applications

You should reinstall elementary to ensure that you get a fully functional system.

However, you can keep a list of the packages installed with

dpkg --get-selections > package-list-file

and backup this file and the packages in /var/cache/apt/archives so that the packages not specific to elementary OS 0.4 would not be downloaded again. This will only work if you have not done any apt-get clean / apt-get autoclean since you have installed the packages.

After the installation of elementary OS 0.4 you can copy every .deb file from you backup medium back to /var/cache/apt/archives. Do not forget to add each PPA that you have used on the original system to the new one before as well. After these steps you  restore packages with

sudo dpkg --set-selections < package-list-file

There might be some packages that you have to install/fix a little but it should work for most of the software installed.


Cannot set up network printer in Juno (worked in Loki)

UPDATE

  All of the hp-setup and installation was unnecessary. After new install and updated elementary OS 5.0 Juno, just open up http://localhost:631 in your browser, click on Administration, then Add Printer. Enter your local username and password. Select Discovered Network Printers of choice (in my case HP OfficeJet Pro 8710) and continue with prompts to create printing defaults. This was rather simple printing configuration and the printer was immediately accessible to the applications.

  For scanning, I decided to use my printer feature and save all my scans directly to a network share. This way I don't have to bother with cumbersome setup and my scans are available throughout the local network.

Okay, I had a bunch of problems it seems but have gotten it to work now. Some of these steps may not be required, but it serves as a record of my troubleshooting steps that may help someone.

I started by removing (or trying to remove) printer from System Settings. Sometimes removing the printer via - icon did not do anything. Printer was still listed.
As part of troubleshooting process, I ran hp-makeuri from command line. For record, I have version 3.17.10 installed on Juno. I did not have to install any packages in particular. This was already installed on my system. When I tried to do hp-makeuri <IP> I received some SNMP errors. I fixed these by:

a) installing snmp via sudo apt install snmp command

b) enabling SNMP on my printer: Network, Advanced, SNMP, Enable SNMPv1/v2 Read-Only access.
During troubleshooting I tried to run hp-setup which gave me dependency errors. I resolved these by installing required sudo apt install python-qt4. I've ran hp-setup to set up network printer. This was okay and it showed up in listed printers again, but I was not able to print a test page to it. I was also not able to remove it from listed printers in System Settings.
Unknown to me before is that you can, on your local system, access http://localhost:631/ web page to manage CUPS where you can manage the print server. I clicked on Administration tab, entered my local username and password, and set up my printer via Add Printer button. Once completed, I clicked Manage Printers and clicked on my newly added printer. To my surprise, my printer was showing to be paused and rejecting jobs. In Maintenance drop-down I have clicked Resume Printer and Accept Jobs. After this printing resumed!

Hope this helps someone. Now, off to get the scanner working...


So I solved my problem.

It turned out I did not actually need to use sudo with these commands.

What I did was to save the 2 commands (without sudo) in a bash script in my home folder.  Then I gave it permissions to be executed by me and my group.  Then, in elementary juno, I went to System Settings > Applications > Startup and clicked the + in bottom left to add the script.

This action creates a file in ~/.config/autostart/ with basic info that results in something very similar to my original screenshot, named Custom Command and with a stock icon.  I was able to clean up the look by editing basic info in this file, like name, and adding an icon in ~/.local/share/icons/hicolor/128x128/apps/ called spacenavd.png.

To test is, I include sudo in front of both commands in the bash script, and execute it from terminal, then in terminal, I am prompted for a password.

But when I do not include sudo in front of either command in the script, and execute it from terminal, then this dialogue box pops in and prompts me to enter my password:

When I boot up and login, I am not given this dialogue, and I believe that's because I have just logged in.

Here is how it looks now:

Here is the spacenavd.sh file in my home folder

You can download and use gparted software visually and directly vis AppCenter on the Loki. After partitioning HDD as you want, you can install windows on the region of storage partiotioned for windows. There are a lot of partiotion software on Linux but when you are a novice, I recommend gparted software on Loki and more thing is that you can use softwares such as LibreOffice or OpenOffice on many Linux distros instead of MS Office on windows.


Can I add a folder icon to a custom folder?

There is an outstanding issue about this on Github here - https://github.com/elementary/files/issues/171
An attempt was made to implement custom overlays to folder icons but it was unsuccessful.  It would probably be easier to enable Files to honour a "custom-icon" metadata attribute but whether the UX team would want the user to completely change icons arbitrarily is another question.


In app centre it is showing failed to fetch updates

The tor-browser package in that ppa has not been updated in a very long time, I do not recommend using it. My suggestion is to remove that ppa, to get AppCenter working again, and then install tor from the ubuntu repository (as per the Tor Project's instructions).

To remove the obsolete ppa:

sudo add-apt-repository --remove ppa:webupd8team/tor-browser

After that, run sudo apt update to see if the error is gone. If all is well, try running sudo apt upgrade to bring your system up-to-date.

AppCentre fails to fetch updates; sudo apt update gives several errors

It looks as though something has replaced the version codename incorrectly in your apt source files (i.e. /etc/apt/sources.list and the other files in /etc/apt/sources.list.d/)
It is likely that some instructions you followed to add a PPA inadvertently caused this, or one of the packages you installed from one of those PPAs did this automatically.
If you are running Juno or Hera (5.0 or 5.1)
You should be able to fix this by replacing all instances of juno or hera with bionic in /etc/apt/sources.list and all of the files inside /etc/apt/sources.list.d/
If you are running Loki (0.4)
You should be able to fix this by replacing all instances of loki with xenial in /etc/apt/sources.list and all of the files inside /etc/apt/sources.list.d/
Further Information
Where possible, it is recommended to install 3rd party apps like Brave via their Snap packaging format (there's an app called Snaptastic in the AppCenter to help with this). Adding PPAs is essentially giving the owner of that PPA root access to your system, and can lead to issues like this if they are not configured properly.


Cannot rename files within the pantheon-files application

I have this problem also. I've had this problem across 3 installations of Loki.

The problem is that pantheon files doesn't seem to save the new name without you pressing enter.

So long as you press enter after typing the new name it works, but if you click outside of the file you're renaming it fails.


To change the transparency in Terminal you can use gsettings like this:

gsettings set org.pantheon.terminal.settings opacity 90

If you are not happy with the result, you can always change it to a different value or reset it to the default like this:

gsettings reset org.pantheon.terminal.settings opacity

To change the cursor shape, you can execute the following:

gsettings set org.pantheon.terminal.settings cursor-shape I-Beam

Or to find out what other options are supported:

gsettings range org.pantheon.terminal.settings cursor-shape

When you use gsettings to set these options, the changes are applied immediately.

You can change the various colors that are used in Terminal with the palette option, have a look at this setting:

gsettings get org.pantheon.terminal.settings palette

An alternative to using gsettings for changing these settings is the graphical user interface tool dconf-editor.
In elementary OS, dconf-editor is not installed by default however.
So, if you want to use this method, you may have to install the package using either Software Center or by running this in Terminal:

sudo apt-get install dconf-editor

Start dconf-editor and go to:

org > pantheon > terminal > settings

Here you can set the transparency using the opacity option or change the cursor shape by selecting a different value for cursor-shape.


Is there a way to add new docklets to plank?

If you are talking about adding icons like the Terminal app to Plank, you can either right click the icon when it's open and click "Keep to Dock", or you can find it in the Applications menu and do the same thing.


go to System setting->keyboard->shortcuts  click on any function on the right box and choose what shortcut u want to use for that function.

Xbindkeys not working on Elementary OS Juno

I couldn't do column selection using Alt+Ctrl+"arrow up"/"Arrow down". Seems to be the keyboard selection in System Settings, Keyboard, "Switch Layout:". I am a European citizen, using "Euro on Five". Switching keyboard layouts is by default defined as Shift+Alt. In Geany this keyboard combination is defined as column selection. Using Shift+Alt changed the keyboard selection in stead of doing column selection.
I changed it into Left-Shift + Right-Shift. Now I can perform column selection in Geany. Maybe this helps you solve the issue.


I guess you want elementary to use localtime instead of UTC to avoid time differences when dualbooting elementary and Windows.

Just execute on terminal: timedatectl set-local-rtc 1 --adjust-system-clock

You can check if that's working with the command timedatectl (may need to reboot).

Does AppCenter update packages I have installed (such as Node.js)?

Yes, it does update packages from PPAs too.


you can open a terminal window and run:

sudo apt-get install vncviewer

However, the package manager will swap it for xtightvncviewer. Haven't used it in about a month, but it's worked well enough for me. Just make sure you have openbox installed on whatever you VNC into.


How can I make wingpanel look right with a 3rd-party stylesheet?

This is largely a problem in the stylesheet you're using not targeting the right style classes for Freya's wingpanel.

The easiest thing to do would be to just switch back to the default stylesheet.

If not that, the next easiest thing to do would be to upgrade to Loki. Loki's wingpanel should work much better with 3rd-party stylesheets. However you may still encounter issues if the developer of that stylesheet isn't targeting Pantheon as an environment.

Alternatively, you can try to edit the stylesheet yourself. But unless you're familiar with Gtk.CSS and using tools like Gtk Inspector this may be difficult and any updates to this stylesheet could break your changes.


Save custom keyboard shortcuts ~ possibly backup other configurations

They are stored in the dconf system registry in a list stored by the key custom-keybindings under org.gnome.settings-daemon.plugins.media-keys, whereas you have a custom… entry for each custom shortcut (keybinding, command and name), for instance:

TL; DR: so you have to backup the ~/.config/dconf folder


How can I take a screenshot of a window without the background?

You can make beautiful screenshots of windows with shadow using screenshot-tool.

sudo apt-add-repository -r ppa:elementary-os/daily

Example:

Supported only GTK3+ apps.


How do I turn off the backlight (laptop)

You could just open up the terminal and type this:

xset dpms force off

Once you press Enter to execute the command, it'll turn off your monitor instantly. This works with every X server. If you press a key or move a mouse, it goes back on (maybe you want to change a song or something). I'm using this method to listen to the music all of the time.


What about sudo makes it less secure than pkexec?

The commands (pkexec and sudo -i) in and of themselves aren't necessarily harmful. However they do different things in terms of granting permissions to apps.

The sudo ("substitute user do") command allows you to run a process as another user, typically the root user. That is, by default it runs the process as a user with unlimited power.

When you use pkexec, you're using PolicyKit. PolickyKit is the part of the system that keeps track of the types of privileges that certain users and programs should have. It depends on certain policy files being defined that describe these privileges. A policy for Ubuntu Software Center, for example, would grant permission to use apt, but it wouldn't necessarily grant permission to change network settings. This kind of control is what the documentation you referenced means by "minimal known and safe environment". The intention is that PolicyKit does not grant more permissions than are necessary.

Why does this matter to you and is it really less safe to run with sudo?

This depends on both the policy written and the app itself. For an app like Files, running with elevated permissions can be pretty dangerous in any case. But imagine that Files had permission to do things you would never want it to do, like create or delete user accounts. Since Files can have 3rd party plugins, imagine that a malicious third party plugin exists that runs in the background and tries to delete accounts. If you've installed software from a PPA or from a downloaded deb, you could already be infected with this type of malware. With a strong PolicyKit policy, Files would never be able to take this action, rendering the malware ineffective. But with sudo, it would have full permissions to make this malicious change.

But what if the policy isn't strong?

It's true that a policy can be written to essentially do the same thing as sudo. However, policies are managed as part of the system's security updates. So running an app with pkexec can actually get more secure over time with updates as stronger system policies are written. Using sudo will always grant full permissions.


Update:

Ended up fixing the issue. Apparently the switchboard color plugin had been removed. Once I reinstalled that, the color setting appears under the settings window.

You can reinstall the switchboard color plugin by running the following:

sudo apt-get install switchboard-plug-gcc-color

then

sudo apt-get install switchboard-plug-gcc-color-dbg

Hopefully this will help anyone else out if they have this issue!


Changing desktop background in system settings does not update the background

Check what is really written to org.gnome.desktop.background.  I see the effect of changing wallpaper immediately.  But if I change the background to solid colour, it gets always black:

I found, that it writes the colour in rgb(...) format to gnome settings:

If I fix the value format in dconf-editor to #..., I see the right background colour.  Setting primary-color to #d0d0d0 helped in my case.

If you cannot select a picture, you can have a look if the actually written path is correct.

How to re-install windows without breaking my eOS

The Windows installation process generally does mess with Grub, the Linux bootloader. One way to prevent such issues is to install Windows in a virtual machine such as VirtualBox.

This answer has more information on how to install Windows and then get your Linux setup working again.

If you've already backed up your data, the simplest option might be to do a clean install of Windows, replacing elementary, then install elementary alongside Windows. This probably sounds like extra work, but in general it's easier to install Linux onto a Windows machine than it is to install Windows onto a Linux machine.

For more information, see Ubuntu's Windows Dual Boot guide.


As user pole mentioned above, the answer can be found here:
mouse right click double clicks?

In the Firefox address bar, type about:config.

Go to ui.context_menus.after_mouseup and set it to true.

Hat tip to user WebShaped.Biz for providing the answer.


I had the same problem, the simple solution is:
just go to appcenter and search for gbedi package installer.

If you want to do it the hard way try

sudo dpkg --add-architecture i386
sudo dpkg --add-architecture amd64
sudo apt-get -i /yourpathhere/skype.deb


The command in terminal is: switchboard settings://notifications

If you enter this command in the Keyboard/Shortcuts as a new shortcut and enter an 'accelerator' (a key combination) this should work.

Error while adding PPA on elementary OS freya

That line 91 line 109 ordeal was a bug. Most of the tickets I found in Launchpad (the bug tracker) went ultimately unresolved, but perhaps they just weren't the main ticket.

Have you tried updating your system and installing "Software & Updates" to install the PPA manually?

sudo apt update
sudo apt upgrade
sudo apt install software-properties-gtk

Has the problem been resolved and does it persist into your Loki upgrade?


Error while compiling latest source of Files

Those two errors are pretty self-explanatory.  Granite.Widgets.StorageBar.with_total_usage and Granite.Widgets.StorageBar.ItemDescription.FILES don't exist in the version of granite you have installed.  You probably need a newer version of granite (quite possibly from git or whatever they use for revision control, if that's where you got files).

Now its normal again, but i'm not sure what made it disappear, this is what i did

run sudo apt-get update -> until this step, warning still shown
restart my laptop -> until this step, warning still shown

And after about one hour, warning disappear, so i think its solved for right now.

Where to propose a new app for elementary OS, discuss design

There were some of such proposals over there at Google Plus. Try it there. Perhaps you will find some developers. However, there is no official platform. Bountysource has an platform for elementary's own applications.

How do I setup and use a USB serial console adapter?

I like using the Parallax USB to serial adapter because it enjoys good support on *NIX operating systems. You can pick them up in the robotics section at Frys electronics in the U.S. for around $17.

After connecting the adapter, run dmesg, you're looking for a few lines at the end like so:

[ 2970.548809] usb 2-1: Detected FT232RL
[ 2970.551218] usb 2-1: FTDI USB Serial Device converter now attached to ttyUSB0

Note the device name 'ttyUSB0'. Run a long list on this to determine which group it is owned by;

$ ls -l /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 Apr  8 09:24 /dev/ttyUSB0

Add your user account to that group. This way you can run the terminal program as a non-root user.

sudo gpasswd -u <username> dialout

Log out and back in for the group change to take effect

Install the picocom terminal utility

sudo apt-get install -y picocom

Connect to the serial console using the appropriate baud rate for your target device and the device name as shown in dmesg earlier

picocom -b 38400 /dev/ttyUSB0

To exit picocom press CTRL-a-x


Whenever dealing with drivers, you first need to remember that elementary os 5.0 is based on Ubuntu 18.04. With this in mind, you might notice that the repository https://download.01.org/gfx/ubuntu/, described in your screenshot, does not contain anything usable above Ubuntu 17.10. You should also know that elementary OS 5.0 already includes the appropriate MESA Intel drivers.

Running the command glxinfo | grep "OpenGL should output something like this:

OpenGL version string: 3.0 Mesa 19.0.8

If, like me, you encountered some issues running some games using the intel graphics adapter, you might benefit from installing the Mesa Vulkan packages:

sudo apt install mesa-vulkan-drivers vulkan-utils vulkan-tools

That being said, if you really need the latest drivers, you could try using the oibaf drivers ppa:

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt-get update
sudo apt-get upgrade

After the upgrade completes, running glxinfo | grep "OpenGL version" again should output the following:

OpenGL version string: 3.0 Mesa 20.0.0-devel (git-3e21e17 2019-12-02 bionic-oibaf-ppa)

EDIT: if, during the update process, you encounter some ppa errors, you might need to do some cleanup first (maybe you added some obsolete repository?). Just run the following command, replacing name-of-the-repository with the name of the one you have to remove:

sudo add-apt-repository --remove ppa:name-of-the-repository
sudo apt update

For example, to remove the one from your screenshot:

sudo add-apt-repository --remove ppa:ubuntu-x-swat/intel-graphics-updates
sudo apt update


Macbook 2010 not booting after update (black screen)

Ok, I found the answer.

Once eOS is installed and booted (stuck on the black screen), Open a tty (find a way to access your command line, like ctrl+alt+fn+F1 on a Mac) and login.
sudo nano /etc/default/grub
Add the parameter nouveau.modeset=0 at the end of GRUB_CMDLINE_LINUX_DEFAULT="".
Save (ctrl+x), run sudo update-grub, and reboot.

Now it works (not sure what are the implications of setting nouveau.modeset=0 performance wise, if any)

After a couple of searches .
The difference between UEFI Boot and Legacy boot is the process that the firmware uses to find the boot target.

Legacy Boot is the boot process used by BIOS firmware. The firmware maintains a list of installed storage devices that may be bootable (Floppy Disk Drives, Hard Disk Drives, Optical Disk Drives, Tape Drives, etc...) and enumerates them in a configurable order of priority. One the POST procedure has completed, the firmware loads the first sector of each of the storage targets into memory and scans it for a valid Master Boot Record (MBR). If a valid MBR is found, the firmware passes execution to the boot loader code found in the MBR which allows the user to select a partition to boot from. If one is not found, it proceeds to the next device in the boot order. If no MBR is found at all, the user is presented with the famous "Please insert system disk yadda yadda yadda"

UEFI boot is the boot process used by UEFI firmware. The firmware maintains a list of valid boot volumes called EFI Service Partitions. During the POST procedure the UEFI firmware scans all of the bootable storage devices that are connected to the system for a valid GUID Partition Table (GPT). Unlike a MBR, a GPT does not contain a boot loader. The firmware itself scans the GPTs to find an EFI Service Partition to boot from. If no EFI bootable partition is found, the firmware can fall back on the Legacy Boot method. If both UEFI boot and Legacy boot fail, the famous "Please insert system disk yadda yadda yadda" will be presented.

In general, UEFI boot is more desirable.

So i let the options as the Default choice (Legacy in my case).

The steps of my installation :

Shrink one of my partitions in windows 10 disk management (30GB) and creating a new partition (E: like exemple).
Create a bootable USB Using rufus (elementary OS Loki 0.4)
Restarting the computer and boot from the USB
install elementary OS ... Choosing the language connect to network (optional)
In the choices of installation in my case i didn't find install alongside win10 so i chose something else
I deleted the partition that i create in step 1 and now i have a 30GB free space, i created one partition for swap (2GB in my case) and one for /home (5GB in my case), the rest for the / partition .
and i can dual boot elementary OS Loki Alongside win10


Can you port elementary's default apps to Ubuntu?

Short answer: Yes.

ElementaryOS uses a framework called Granite in which all its apps heavily relay on. If you manage to install the Granite Framework and its dependencies on Ubuntu (GNOME) yes, theoretically you could have eOS apps on Ubuntu.


Compatibilty Brother DCP-J152W with Linux Elementary

Try to download the linux (deb) drivers from Support page. (I would try it with the Driver Install Tool from this mentioned support page.) Maybe you need to install a deb package manager first (sudo apt install eddy), but I did not try to install the printer drivers.

Then follow the install instructions on the support page:

  Step1. Download the tool.(linux-brprinter-installer-..-.gz)

  The tool will be downloaded into the default "Download" directory.
  (The directory location varies depending on your Linux distribution.)
  e.g. /home/(LoginName)/Download

  Step2. Open a terminal window.

  Step3. Go to the directory you downloaded the file to in the last
  step. By using the cd command.

  e.g. cd Downloads

  Step4. Enter this command to extract the downloaded file:

  Command: gunzip linux-brprinter-installer-..-.gz

  e.g. gunzip linux-brprinter-installer-2.1.1-1.gz

  Step5. Get superuser authorization with the "su" command or "sudo su"
  command.

  Step6. Run the tool:

  Command: bash linux-brprinter-installer-..- Brother machine name
  e.g. sudo bash linux-brprinter-installer-2.1.1-1 MFC-J880DW

  Step7. The driver installation will start. Follow the installation
  screen directions.

  When you see the message "Will you specify the DeviceURI ?",

  For USB Users: Choose N(No)   For Network Users: Choose Y(Yes) and
  DeviceURI number.

  The install process may take some time. Please wait until it is
  complete.


Wing panel and dock disappeared elementary os Loki


I did more research and discovered that the Adafruit boards like the Trinket, Pro Trinket, Gemma, etc. do not show up in the serial port menu when connected via USB. You select the proper board, set the Programmer option to "USBtinyISP" then press the reset button on the board to enter bootloader mode and upload the sketch.

The older tutorials Adafruit and Arduino websites all mention selecting the connected board from the Port menu. This is still true for boards with USB chips like the UNO. I was way over thinking this. Sometimes the answer is so simple it seems it can't be correct.

Cant install 7zip on elementary OS 5.1 Hera

This error means that snap is doing something in the background. You can see what is going on by typing the following in the terminal:

snap changes

If after some time the situation doesn't resolve itself you can abort any of the processes that are listed by typing:

sudo snap abort id

NOTE:  "id" should be replaced by the number at the beginning of the row of the process you want to abort (e.g. sudo snap abort 123)


First ensure you have Allow louder than 100% unchecked in the sound settings, as peaking audio is generally the cause of terrible audio quality, and can damage speakers sometimes.

Second, you can try editing your deamon config file (although back it up it first):
Local version: ~/.config/pulse/daemon.conf
System wide version: sudo nano /etc/pulse/daemon.conf

You will probably not have a local version so you can cp /etc/pulse/daemon.conf ~/.config/pulse/daemon.conf first and then try and edit it.

Here are some possible changes (suggested here):

default-sample-format = float32le
default-sample-rate = 48000
alternate-sample-rate = 44100
default-sample-channels = 2
default-channel-map = front-left,front-right

default-fragments = 2
default-fragment-size-msec = 125
resample-method = soxr-vhq
enable-lfe-remixing = no
high-priority = yes
nice-level = -11
realtime-scheduling = yes
realtime-priority = 9
daemonize = no

Now to test new settings:

pulseaudio -k
pulseaudio -D

Hope that helps!


Why can't I enable the various upstream repositories?

Try opening the "Software Updater" app instead of "Software & Updates". Does a list of updates appear? (After a fresh install of Freya, you should see a bunch of updates.) If you click "Details of Updates", do you see anything other than "Elementary Base"? If so, those are most likely from trusty-updates or trusty-security.

If you answered "yes" to both of those questions, then your updates are working properly, and the Software & Updates app has a UI bug. It's frustrating for sure, but I believe this app is slated to be removed in the next version of Elementary and replaced with Elementary's own software center.

The good news is that unless you plan to add third-party PPAs, you can generally ignore the "Software & Updates" app. The fact that Ubuntu has a Software Center and two different "Software Update" apps drives me bananas, personally! :)

I'm experiencing this issue, and Software Updater is telling me I have no updates. As far as I can tell, third-party PPAs that I added are misbehaving, and Software & Updates is doing a poor job of explaining exactly what has happened. Here's how I fixed it:

Open the "Software and Updates" application.
Go to the "Other Software" tab.
Look for third-party PPAs, and disable them. The third-party ones will have a URL (not a name such as "Recommended updates"), and that URL won't start with http://ppa.launchpad.net/elementary-os.
The checkboxes in the updates tab still won't check. This is totally fine.
Run the "Software Updater" application. You should now be able to get updates. If you click "Details of Updates", you can see the actual packages that will be updated.

Optionally, after things are fixed, go back and re-enable PPAs one by one and see if anything breaks.

Possibly related: this bug in Launchpad.

Edit: Here's an Elementary ticket for this bug. Looks like the bug will be fixed in 0.4.

How do you access the command line boot menu when not dual booting?

You have to pres Esc key once before the elementary logo appears.
Or, if you're not fast enough, edit grub file:

sudo nano /etc/default/grub

Comment (place a # before) the two timeout lines, just like in the image bellow:

Ctrl + o to save the modifications

Ctrl + x to exit nano

sudo update-grub

sudo reboot

Now you'll get the GRUB screen, with a 5 seconds delay and you'll be able to do your thing. To revert, just un-comment those two lines and run update-grub again. I recommend not modifying anything else, unless you know what you're doing...


Remove Spotify sudo apt remove --purge spotify
Then install Spotify using a flatpak. There are plenty tutorials in the Google how to do this via flatpak.


I do not really understand what you want to do very well. if you intend to install the software "(driver)" from amd en wine, I regret to tell you that it will not work, if what you want to install is the driver provided by amd you should do this:

Download the driver from the official website of amd.

Depending on the version of the driver you will need to edit the system file / etc / os-release on line 3 ID=elementary to ID=ubuntu on line 6 of VERSION_ID = "5.0" to VERSION_ID = "18.04" (open "files" with administrator privileges for to be able to make the change).

If you do not know that, it will say OS not supported.

After that open the folder where the driver is with the terminal and put there:

./amdgpu-pro-install -y

(this installs Base kernel, Accelerated graphics, Multimedia table, OpenGL Pro, Pro Vulkan, Pro OpenCL).

After installing everything correctly edit the system file / etc / os-release again, on line 3 ID=elementary on line 6 of VERSION_ID = "18.04" to VERSION_ID = "5.0" to leave that file as it was before.

How can i dual boot elementary OS Freya and Windows 10

I had the same problem as you have. I read at many places including StackOverflow that I need to disable the "Fast Boot (Startup)" and "Hibernate" options in the power options when I'm logged into Windows. I did that, but the problem was not solved. elementary OS was still not able to detect the Windows installation. So here's what I did:

While logged into Windows, disable fast boot and hibernation in the power settings.
Open disk management (you can go there by pressing  keys or just type disk management in the start search). Here you need to have a big enough space that is unallocated (shown in black color). If you do not, then make some space by deleting and moving partitions. Make sure you don't have too many partitions.
Boot with elementary OS live drive and while installing, choose "Do something else", instead of "Erase everything ..."
Create two partitions from the unallocated empty space that you see (we created this earlier in step 2). The first partition will be of type "swap" and about 2-3 GB should do good here. The second partition is your linux partition, which you can set to use all the remaining available space. Set the mount point as "/" (root) for the second partition and set it to type "ext4"
Now continue with the installation, all should work fine. Be careful not to erase a partition with data when making empty space in step 2.

Hope this helps! Cheers.


Freya cannot shutdown. init: wait for state plymouth shutdownlightdm killed by TERM signal

Try sudo shutdown -h <time in minute>

Example sudo shutdown -h 0

Try sudo shutdown -r <time in minute> for reboot in time.
Reboot can also use sudo reboot

Solution 1:
Edit /etc/default/grub file

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash reboot=pci"

Then run sudo update-grub

Source -- Link

Solution 2:
Edit /etc/default/grub file

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT=""

Then run sudo update-grub


Running "operating system updates" in appcenter of Elementary gets cancelled

I found this solution here:

sudo rm /usr/share/doc/libperl5.22/changelog.Debian.gz
sudo apt install -f

I hope this fixes it for you too!


Sometimes the dock and top bar do not appear on elementary Loki. What to do?

I usually just Ctrl+Alt+F2 login to command line and reboot. It then goes away.


Download a Ubuntu live CD, extract it on a pen drive with unetbootin or any similar tool and start the installation process.

Don't forget to backup your data.


You can install redshift from repository ufficial of Ubuntu/Elementary OS.
Just run it in your terminal:

$ sudo apt-get install redshift redshift-gtk
$ sudo apt-get install libxcb1-dev libxcb-randr0-dev libx11-dev
$ sudo apt-get update
$ redshift

I've run it and work!
You can use redshift -h for help, and you can run redshift -m list  and use randr/vidmode.

For other help you can use documentation from terminal with man redshift.


How do I type in multiple languages on elementary OS?

Go to Settings - Keyboard - Layout (3rd tab). Add a new language by clicking the plus sign (+) at the bottom left and selecting it from a list.

-Tip: You can quickly change between distributions by pressing Alt+Spacebar. The shortkey can be edited under Settings - Keyboard - Shortcuts - Universal Access - Next Keyboard Layout

Also, after adding multiple keyboard layouts, they should be accessible in a panel applet and be switched from there too with the mouse.


How does The login sceen knows my custom wallpaper if i have my home folder permission to 700?

The answear is that it makes a copy with the same permissions in the root folder /var/lib/lightdm-data/.

This way no matter what your home folder permissions are you will always have the choice to show or not your wallpaper on the login screen by giving the wallpaper file read permissions to others.


If you type 0 in the Custom box, the Purchase button turns into a Download button.


The answer is no I am afraid, you will need to perform a clean install. Download Juno from here, https://elementary.io. Don't forget to backup your data.


This answer is after the discussion in chat

Here you have to do two things ,

1 . Deleting the /swapspace file created using AU question.
2 . Creating swap in unallocated space.

1 . Open terminal and run the commands:

sudo swapoff /swapspace
sudo rm /swapspace

2 .  Install gparted,

sudo apt-get install gparted

Note Careful while selecting partition.

Open gparted and select unallocated space.

Right click on it , select new

Then select file system as linux-swap and logical partition(If not possible select primary partition)

Then , right click on partition and make swapon

Note Don't forget to apply changes

You can verify swap by the command

cat /proc/swaps

Next, add the following line to /etc/fstab to activate the new swap at boot:

/dev/sdb3 none swap defaults 0 0

(Replace /dev/sdb3 with your swap partition)


How to set audio input to internal mic when plugging headset?

A workaround for me is using pavucontrol. Install it via AppCenter or

sudo apt-get install pavucontrol

Start it and choose your internal mic. Try to mute your external and unmute your internal mic via the button in the screenshot.
