I completely removed a pulseaudio mod I installed last year and also completely purged all the audio drivers.I then installed aptitude based on some recommendations and used that to reinstall all the stock ubuntu audio drivers using --purge along with reinstall. Still after that I had no sound.The key was running this command and rebooting:killall pulseaudio; rm -r ~/.config/pulse/* ; rm -r ~/.pulse* I stole that code from the ubuntu help page at: https://help.ubuntu.com/community/SoundTroubleshootingProcedure.If anyone else has problems hope this helps. I still cannot use the dedicated volume buttons on my keyboard. I'll work on that soon, at least my speakers work now.


Good point! You should definitely report this UI design flaw to elementary OS developers @ https://github.com/elementary/wingpanel-indicator-notifications


You're using a GTK theme that's not created for elementary OS.

The only way to fix this is to change back the GTK theme to the default theme (or one that does support elementary OS), or to ask the creator of the theme if he/she wants to add support for elementary OS.


Prevent Spotify notification from making sound

Spotify doesn't register its notifications with the system properly and since its development future appears spotty, my solution for now is to turn off sounds in the "Other" notifications option. This deactivates sounds for all unregistered applications, but such is the way of things.

How to modify scratch text editor bracket completion plugin?

You have two ways to get a new brackets completion plugin.

The first one is to propose to developers a modified version in order they accept it and add it to the next update. You can do that by opening a blueprint in the Scratch website at launchpad.net

To open a new blueprint, visit https://blueprints.launchpad.net/scratch

The other way, if you know Vala, is to copy the plugin code from launchpad.com and make your changes, debug and test your plugin. Once it's ready, you can upload to your Launchpad or Github account and import it to a new branch of Scratch at Launchpad and propose it to merge.

Meanwhile developers decide, you can build it in your system to use it.


Will it break my system (elementary OS Freya 0.3.1) if I completely remove pantheon-files?

Haven't try it yet, but I don't see much of a problem.

elementary OS is build on top of Ubuntu. And Ubuntu works fine without Pantheon Files :D

Just remember to install Nautilus, Dolphin or other file manager if you don't want to see your files only via terminal.

If it happens to remove other features from elementary OS, just reinstall the package elementary-desktop. That should reinstall all the packages needed for elementary, including the pantheon-files.


I am using an R9 270 by Sapphire, so this may or may not apply to you.  I installed the driver by using 'additional drivers'.  I typed 'drivers' in the Applications search box and 'additional drivers' popped up.  It found fglrx AMD/ATI proprietary drivers, clicked install, then rebooted. Everything is working great.  If this doesn't work you you (like you get black screen upon bootup,) you can try pressing Ctrl+Alt+F1 to get to a terminal then try sudo apt-get install fglrx. then sudo reboot.

(If you ever use Ctrl+Alt+F1 to get to a terminal and need to get back to a GUI (assuming your GUI is working properly) you can press Alt+F7)


Getting default Calendar app to work with University account (outside auth)

Yes, go to your account preferences and find a link called App passwords. Click on it, and create a new password profile (name it whatever you want). Google will then generate a new password to use with the app instead of your usual log in password. Hope this helps.


Add to Startup an application that is not showing

In some cases installed applications are not present in the available list of applications that can be added to the startup list, but you could just add the path to your application executable into the "command box" (the little box where you can add a custom command to run)

/path/to/telegram-folder/Telegram --

Press enter and make sure it is ticked to run and you should be fine.


Where to find about arguments/options of Pantheon Terminal?

There is a handy manpage for Terminal:

First of all the only way to upgrade Freya to Loki is to reinstall elementaryOS. So if you didn't fresh install Loki I suggest you to do so, to prevent errors like this one to happen.

Second, in Loki the Software Center was removed to give place to AppCenter.


These symptoms sound like an issue that has been reported and now fixed related to certain plugins crashing Code: https://github.com/elementary/code/issues/619

A new version incorporating the fix was released in early March 2019.

For future reference, it is possible to reset all of Code's preferences to default with the following command in the terminal:

dconf reset -f /io/elementary/code/

This often resolves issues with code relating to plugins or documents its trying to re-open that are causing issues.


In Files is it possible to sort folders together w files, rather than folders separate from files, like how files are sorted in the open/save boxes?

To my knowledge, there is no such option.

In fact, I'd find it very counterintuitive, but maybe it's just me.


There is a daily PPA, and it looks like many of the packages have been updated within the last month:

https://launchpad.net/~elementary-os/+archive/ubuntu/daily


I still cannot say what the problem was, I tried now after a few months and everything works as it should.

A big thank you goes out to Ryan DeBeasi !

Is there a way to set a "scroll zone" on the right side of the touchpad?

You can change it in System Settings (internally called Switchboard) in the Mouse & Touchpad pane.

0.4 Loki

Set the value of "Scrolling" to "Edge".

0.3 Freya

Untick "scroll with two fingers", which in turn will enable edge scrolling.


I would suggest using a partition manager utility such a GParted Live (either the CD or USB version), delete all partitions on the hard drive, reboot, and then try installing it clean.
If that fails, you could also try using a utility such as DBAN (Darik's Boot and Nuke) - that will pretty much guarantee complete hard drive, partition, etc. erasure.  Kinda extreme maybe, but I've encountered drives where either the partitions wouldn't remove properly, or there was a problem with the MBR (master boot record), and DBAN solved it.

Finally, if DBAN doesn't work.  Get another hard drive / SSD.   If you have problems after that... well, maybe the RAM is bad.  (generally replaceable).
 If after all that you're still having problems, then more than likely you're having some other hardware failure, and maybe time to get a new system.


This should do the trick:

sudo add-apt-repository ppa:detly/mactel-utils
sudo apt-get update

If you are missing add-apt-repository:

sudo apt-get install software-properties-common python-software-properties


sudo sh -c 'echo "deb http://archive.getdeb.net/ubuntu xenial-getdeb apps" >> /etc/apt/sources.list.d/getdeb.list'

wget -q -O- http://archive.getdeb.net/getdeb-archive.key | sudo apt-key add -

sudo apt update

sudo apt install vuze

sudo apt remove vuze && sudo apt autoremove


Wacom settings nowhere to be found on Hardware Settings

the switchboard-plug-gcc-wacom 0.2.0-0~77~ubuntu0.4.1 which was installed in Loki is missing in Juno. You can change your Wacom settings with xsetwacom in Terminal.

Open Terminal and type xsetwacom --list devices

If you see your tablet there, you can change it settings. For example:

xsetwacom set "Wacom name of your tablet" Mode Relative

This command changes to Mouse Mode.

After that you can add your command to the Startup Applications in Juno.

Getting started with gtk.grid with error

It looks like the docs are a bit unclear about this. Your fix is absolutely correct. You want to add your Gtk.Grid to a Gtk.Window as the window's widget. By using window.add (grid) you're doing exactly that, so it's fine that way.

Now let's talk about what the docs are actually trying to say in the paragraph about GtkGrid. Most of the time, you don't want to create a Gtk.Window object. You want to create a custom class based on Gtk.Window which configures the Gtk.Window-specific attributes and adds all your widgets. Take a look at how Pantheon Calculator is doing it: This is the MainWindow-class. It's a class which inherits Gtk.Window and handles all the logic inside its constructor. The custom window is used here which is a Granite.Application created by the main function.

this is always referring to the current class you're in - so you can only use this.add (...) when you're actually in the Gtk.Window you're using.

You might notice the linked class actually doesn't use this. Why? Because you can call a function inside a class and it will look for a function named that way in your class and inherited classes. That's why you can simply use add (...) in your window class as well. However, using this might be a nice rule because you are always aware of the function's context you just called.


Intel PRIME profile causes freezing on boot

I've stumbled across a solution that seems to work. The problem seems to stem from the fact that if the discrete Nvidia GPU is switched off before starting Xorg, the system freezes.

The GitHub repo here provides a way to manually disable/enable the discrete card after starting the graphical session.

I followed a different set of instructions reiterated below:

$ sudo apt install git cpio iasl
$ git clone https://github.com/m4ng0squ4sh/razer_blade_14_2016_acpi_fix
$ cd razer_blade_14_2016_acpi_fix
$ sudo make all && sudo make install

Then, modify a boot-time config file

$ sudo vim  /etc/grub.d/10_linux

There is a block of code around line 200 that reads something like

EOF
    fi
    sed "s/^/$submenu_indentation/" << EOF
        initrd  ${intel_ucode} ${rel_dirname}/${initrd}

or

EOF
    fi
    sed "s/^/$submenu_indentation/" << EOF
        initrd  ${rel_dirname}/${initrd}

Edit the line last line to read

initrd  ${rel_dirname}/razer_acpi_fix.img ${rel_dirname}/${initrd}

or

initrd  ${rel_dirname}/razer_acpi_fix.img ${intel_ucode} ${rel_dirname}/${initrd}

depending on the original construction.

Saving the file, ensuring I'm on the intel profile with sudo prime-select intel, updating the grub with sudo update-grub, and finally rebooting seems to avoid the system locking up.

TLDR: Uninstall and remove brave from your source, then run this on the terminal if you are using Juno.

curl https://brave-browser-apt-release.s3.brave.com/brave-core.asc | sudo apt-key add -

echo "deb [arch=amd64] https://brave-browser-apt-release.s3.brave.com/ bionic main" | sudo tee -a /etc/apt/sources.list.d/brave-browser-release-bionic.list

sudo apt update

sudo apt install brave-browser brave-keyring

Why it works

As of nov 2018, official instructions looked like this:

curl https://brave-browser-apt-release.s3.brave.com/brave-core.asc | sudo apt-key add -

echo "deb [arch=amd64] https://brave-browser-apt-release.s3.brave.com/ `lsb_release -sc` main" | sudo tee -a /etc/apt/sources.list.d/brave-browser-release-`lsb_release -sc`.list

sudo apt update

sudo apt install brave-browser brave-keyring

The command lsb_release -sc prints the current version of the OS, in this case juno. But that does not make a valid source as brave does not have that url. However, Juno is based on Ubuntu 18, codename bionic. So we can edit the official instructions to use that as a source.


Add the following at the end of the file:

sudo pantheon-text-editor /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf

vpaths-output = analog-output analog-output-lineout analog-output-speaker analog-output-desktop-speaker
priority = 10
direction = output

sudo pantheon-text-editor /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common

[Element PCM]
switch = on
volume = ignore
override-map.1 = all
override-map.2 = all-left,all-right

Then create this file and add that one line.

pantheon-text-editor ~/.config/pulse/daemon.conf

enable-lfe-remixing = yes

Now install this packages sudo apt install cmt blop ladspa-gtk

Lastly, you need to create this file but now you'll have to change alsa_output.pci-0000_00_1b.0.analog-stereo-21 to the output of pactl list sinks | grep Name (Omiting the "Name" word). If you have more than one, ask me first.

Why I can only launch linssid from terminal using sudo

I think this is because an outaged version of linssid in appcenter (2.9 I guess). The way how to get Super User privileges in GUI has meanwhile probably changed (you will need administrative privileges to sniff network traffic).
You can download an updated version from here and install the deb manually or add a ppa to your system and install via terminal:
sudo apt-add-repository ppa:wseverin/ppa
sudo apt update
sudo apt install linssid

Please consider this (old but still relevant) question and answer when adding external repos to your system.


It's a bug in elementary's patch to remove the app menu. Here is the bug report.


Most of the applications can be removed from the Dock by just click and drag outside of the Dock, but for some of them this do not work. Usualy when you right click (or tap with two fingers if you use a trackpad) over any icon on the dock - there is an option that says keep in Dock. Uncheck it and this should remove the app or folder from the Dock.

If none of these works, open your files manager, Show hidden files with right click inside the right panel, navigate to you home folder > ~/.config/plank/dock1/launchers and delete the corresponding .dockitem file.


What size boot partition does elementary OS 6 Beta need?

209MB for a /boot partition is a little tight. This could make it rather difficult to install kernel updates. Some people are able to get by with a small /boot, though I tend to keep mine at 1GB in size. This allows for a good deal of breathing room so long as you can afford to forfeit the storage space.
As for your second question, it's not a terrible idea to use the recovery partition on a Mac if you are not using macOS very often or do not plan on upgrading the OS. Worst case scenario is that, if you need to re-install macOS from scratch for whatever reason, you make use of the Internet Recovery feature by pressing ⌘ + Option + Alt + R at boot time. Restoring macOS will blow away all partitions on the storage device, though, so be sure to have good backups


Packagekitd is responsible for handling package operations (installation, uninstallation, updating, etc...) for AppCenter. It runs in the background so it can check for updates and await commands to perform actions via AppCenter.

There is a command called pkmon that will show you what actions packagekitd is performing in the background if you wanted to check.


Can no longer long in after trying to apply updates

ok I fixed this by going into the CLI and fixing apt as when I tried to run the update it said the previous update attempt had been interrupted so needed a manual command to resolve.

How to purchase elementary OS on the company? (No option for entering Company Name and VAT Number)

If you pay from a credit card that belongs to your company, and not you personally, maybe it's enough. Talk to an accountant about it, maybe by paying with the company's credit card, even without VAT, you can deduct the expense. Or maybe the accountant can book it as a donation, which technically it is. (I can't give you a definitive answer, bookkeeping varies from country to country.)


Wifi connectivity issue during the installation of Freya

That wifi adapter is based on Realtek 8192CU chipset,  with known bugs on Ubuntu and derivates.

If you can connect to inet from another pc, you must try to download a driver ported to kernel 3.13 and above, from the next address :

Github.com pvaret

Download the. zip file and copy it to a usb drive to paste in your elementary OS pc.

Once it will be in your pc, extract and rename the folder as "realtek8192cu-fixes". Open panthon-files as root and paste this folder to "/opt". Open Readme.md file inside the folder and follow the instructions.

If you need some aditional help, you can comment this answer.

UPDATE:

According to Readme.md file, I'll try to explain the installation steps:

Open a terminal window or simply press Ctrl and T keys.
Then you must execute: sudo pantheon-files and put your password when you ask for it. Now you have opened Files as root.
Copy rtl8192cu-fixes folder to /opt folder.
From /opt , click the right button mouse and choose Open in ... Terminal option. Now you can see a new terminal window prompted to /opt folder.
Execute sudo dkms add ./rtl8192cu-fixes.
If an unknown command error appears, cause you haven't installed dkms , you can download to another computer the dkms trusty packages from: Ubuntu trusty packages. Copy to elementary OS pc and install it with the command: sudo dpkg -i dkms_2.2.0.3-1.1ubuntu5.14.04.5_all.deb. Try again with sudo dkms add ./rtl8192cu-fixes.
Execute sudo dkms install 8192cu/1.10.
Execute sudo depmod -a.
Once your new driver is installed , remove your old one from boot with sudo cp ./rtl8192cu-fixes/blacklist-native-rtl8192.conf /etc/modprobe.d/
And finally you must disable power management executing sudo cp ./rtl8192cu-fixes/8192cu-disable-power-management.conf /etc/modprobe.d/.

Reboot your system and try to connect via wifi to your rooter.

7) Reboot: shutdown -r now


How do I get Elementary OS to detect my display?

I’m also new to Linux and just posted a very similar question recently. I answered my own post with what worked for me. The research was challenging but once discovered the solution was easy. Here is my post link...
How to add 1920x1080 Display option and make it survive restart
Also a link to where I found the answer...
http://ubuntuhandbook.org/index.php/2017/04/custom-screen-resolution-ubuntu-desktop/
If you read the second link first it may give my post some context. If this doesn’t provide enough assistance let me know and I will offer more precise guidance. Sleep is upon me!
Edit:
Here is an additional link with the info you need...
https://www.tecmint.com/set-display-screen-resolution-in-ubuntu/
Please note that in my case, the code used to create the new .sh file in profile.d (namely this code):
sudo vim /etc/profile.d/external_monitor_resol.sh

is to use vim text editor. I think Elementary comes with gedit text editor so I used this code in place of the example:
sudo gedit /etc/profile.d/external_monitor_resol.sh

That opens a new file that you will add the newmode & addmode codes and you simply press save and the file called external_monitor__resol.sh will be created and saved in the profile.d folder within etc.
I hope that is helpful.


gsettings doesn't works to desactivate single-click in pantheon-files

Dual boot elementary OS and Vector Linux

I think the problem is that the grub config is messed up. To solve it, do the following:

sudo pantheon-text-editor /etc/default/grub

The file should have a part like this, make sure the options are the same and that everything else on the file is commented out ( # in the beginning of the line).

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=
#GRUB_HIDDEN_TIMEOUT_QUIET=true
#GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

Then save the file and run sudo update-grub. Check the output, it should say something about every system you have installed (if you don't see anything regarding Vector Linux, there's another problem..).

Also, I've set grub to always show at boot and wait until you select one option. If you want to boot any option automatically, uncomment GRUB_TIMEOUT and set it to any number greater than 0. E.g: GRUB_TIMEOUT=5


I have this sometimes. It appears as if it's just the screen that's turned off. When I type my password and press enter it turns on and I'm logged in again.


I noticed in alsamixer for the sound card of my headset a dedicated volume column to Mic, in the F3: Playback view (and not F4: Capture!), lowering it to 0 solved my problem.


How to encrypt home folder after installing ElementryOS Loki

First, install sudo apt-get install ecryptfs-utils cryptsetup. You'll need to encrypt your home folder while you are logged out,  so u need to change account-it has to be account with sudo privileges.

Login to the other account.

Then run sudo ecryptfs-migrate-home -u user and replace user with name of your account (the one that you want to encrypt).

Ta-da! Your home folder is encrypted. Afterwards:
1.Login to your encrypted account immediately. (Do not reboot before that!)
2. Click *Run this action * to create passphrase

In installation process system encrypts also your swap partition, so to encrypt it use sudo ecryptfs-setup-swap.

That's everything. :)

How do I get rid of a "desktop inside of a desktop" bug?

This worked with Luna, you can try and see if it still works (taken from this answer):

If you install Nemo you might end up with an "un-closable" window in your desktop that you can't close (see here).

To fix this you need to add --no-desktop to the nemo.desktop file so it reads:

Exec=nemo --no-desktop %U

If you right click on any of them it will display the option for marking package for reinstallation,removal, etc. Mark the following packages for reinstallation:

gala, libgala0, libmutter0g

Click Edit > Apply Marked Changes. Click Apply on summary window.

Reboot your computer.

You need to download the files marked with a black line.

Then save it to any folder on your HP 17z laptop.
Press right click> open in terminal and write the following on the window that appears: sudo apt install ./lin*.deb. This should install everything, now you need to reboot and it should be done!


some keyboard buttons don't work(calc and file shortcuts)

Probably you need to add shortcuts for them.
In System Settings >Keyboard you'll find shortcuts for variety of functions and you can change keys to use these functions.

If you want to add a custom shortcut, go to the last tab where you can create your own shortcut - you define terminal command that is performed on event of clicking for example your calc key (maybe open calculator or libre office calc)


It seems that you've upgraded python3 version. As explained here https://askubuntu.com/a/1191220/607679; because of the python3 update, usr/bin/python3 points to a python that does not have apt_pkg.

You can create symlink like below. This should your problem.

ln -s /usr/lib/python3/dist-packages/apt_pkg.cpython-36m-x86_64-linux-gnu.so /usr/lib/python3/dist-packages/apt_pkg.so


elementary OS Juno - desktop vanishes after boot

I run

sudo apt update

sudo apt full-upgrade

reboot

and all good.

I hope this will help somebody else :)


To boot into single user mode you edit the boot instructions for the GRUB menu entry you wish to boot and add the kernel parameter/option single. Brief instructions for how to do this are below.
Turn on laptop and wait when GRUB menu will appear. Select (highlight) the GRUB boot menu entry you wish to use. Use the first one entry in this case.
Press e to edit the GRUB boot commands for the selected boot menu entry.
Look near the bottom of the list of commands for lines similar to

linux /boot/vmlinuz-5.7.0 root=UUID=bc6f8146-1523-46a6-8b
6a-64b819ccf2b7 ro quiet splash initrd /boot/initrd.img-5.7.0

Change the line by removing quiet splash and by adding the kernel boot parameter single to the end of the line (it should look exactly like this: ro single).
For this example you would change:

6a-64b819ccf2b7 ro quiet splash

to

6a-64b819ccf2b7 ro single

Press either Ctrl+X or F10 to boot using these kernel options.
Note: These changes are not persistent. Any change to the kernel boot options made this way will only affect the next boot and only if you start that boot by pressing either Ctrl+X or F10 while still in GRUB edit mode.
Then run the system and see errors on the screen and provide a photo of the screen with errors or information the system shows.
Then you should hit Enter to go into maintenance mode and type in terminal.
journalctl -xb

and hit Enter.
It will show you all information from the boot start process to the end, I mean to the moment you hit Enter to go into maintenance mode. To quit viewing hit q.
Provide screenshots. Use arrows or PgUp PgDown to scroll text in the screen.
To restart type:
systemctl reboot

And hit Enter.
Then you can repeat all steps but instead of hitting Enter, hit Ctrl+d to run the system.
See will it load with default options.
The same effect you will achieve when you will hit Enter instead Ctrl+d and then type:
systemctl default

and hit Enter.


Is there a way to make Noise automatically update music library?

Theoretically, this should be regulated by one of the options in the settings dialogue, as I understand it.

It has not been working for me, however and I have to re-scan the library manually every time I want Music to acknowledge a change I made.


No wingpanel after installing indicator-synapse

First remove the installed indicator synapse:

Open terminal using shortcut (Win + t, if you not modified)

sudo apt-get remove indicator-synapse

Now logout/login. Your wing panel will be back

To install without effecting wingpanel :

I have found similar bug report (status:invalid) here.

From the post:

  The crash seems related to the fact that indicator-synapse was built using libgee 1.0 instead of libgee 0.8.

The solution:

Manually install indicator-synapse.

Download package,  for 64-bit and for 32-bit.
Install from Software Center.

Note: Once you update synapse via package manager the problem of course will reappear.(Quoted from the same link)

To eliminate that, hold the indicator-synapse

Why do I have multiple linux image? How to remove one?

No, you don't. (You have as many Linux operating systems, as you have system root directories, which are usually marked with a forward slash, /.) The items in the list are not different operating systems, but different Linux kernel version images, available to your OS.
On how to remove older kernel versions, refer to this post.
For some reason, newer kernel version hasn't been properly installed. (Despite newer kernel (.64) being available, your system still uses older version (.62). Try:

sudo apt update && sudo apt dist-upgrade && sudo apt autoremove


How to remove notepad from Files/open-with context menu?

As posted in this askubuntu answer:

"wine-notepad creates a local mime association for text/plain and some other types in the file ~/.local/share/applications/mimeinfo.cache; this effectively allows it as an alternative to anything gedit (or your default GUI editor) would otherwise open"

What I did (as also said in a comment under that answer): deleted altogether the file ~/.local/share/applications/mimeinfo.cache. "everything seems to default to my editor of choice".


How do I view attachments in the default email client?

Double click on the email so that the preview/viewing pane opens up and then they're just below that.
I made you a helpful graphic:

You can double-click on the attachment and open it in the default client. If you right click on it, your choices are 'open' and 'save'.
After a few tests, they all showed up. If you're unable to see an expected attachment, I'd suspect that it's a malformed email. I was able to send and receive several emails with attachments in short order.
Tested with eOS Here 5.1.7


after 2 day trying I fixed  it by:
my laptop webcam is 05ca:1839 and the driver is r5u87x.
so I did these steps:

for converting from rpm to deb
sudo add-apt-repository universe
sudo apt-get install alien
sudo alien r5u87x-firmware-0.2.0-15.a9b2171d762b.fc33.aarch64.rpm
for installing deb file:
sudo dpkg -i r5u87x-firmware_0.2.0-16_amd64.deb
adn sudo apt-get install libglib*-dev libusb-dev build-essential gcc automake mercurial
for enabling
xinput --list
xinput enable 7
and
sudo modprobe -v uvcvideo
sudo modprobe uvcvideo
restart and enjoy.


Sounds like you have another install process running. Do you have another package manager like Synaptic running? if nothing else is running try a reboot. Also try updating from the terminal rather than the app center: sudo apt update && sudo apt upgrade

The file you downloaded is a script. After downloading it, you must mark it as executable and then run it in Terminal.

Right-click on the .run file, and go to Properties. Here, go to the Permissions tab and click on the first Execute button and then Close.
Open a Terminal window and then drag-and-drop the .run file inside, and press Enter. Type your password when prompted.

You are correct that most system settings are stored in gsettings which is not plain-text. Typically a tool called dconf Editor is used to manually view and manipulate settings. You can also interact with gsettings using the Terminal command gsettings as you've already discovered.

It's not really meaningful to think of where gsettings are stored in terms of the filesystem. It's more useful to think of where gsettings are stored in terms of Schemas separated by ., like DBus. Take your example above org.pantheon.desktop.gala.behavior hotcorner-topright. This describes a location in a tree. See this screenshot of dconf Editor:

As to where settings are stored by plug, settings aren't really organized in that manner. A plug could change the settings of many different system components. However, many of the plugs will manipulate children of org.gnome.settings-daemon.plugins since that contains settings related to a lot of lower-level system stuff. As an example, the Mouse & Touchpad plug will touch settings in both org.gnome.desktop.peripherals and org.gnome.settings-daemon.peripherals

You can read more about gsettings in its GNOME documentation or on Valadoc.


Low disk space in root file system error

It is solved. I formatted an NTFS partition as ext4 and moved to it many files, so I have enough free space now.


This will be fixed in the next release: https://github.com/elementary/switchboard-plug-applications/pull/15
I don't know whether it will be released in Loki.


How can I change keyboard shortcuts for Epiphany?

After some digging, this appears to be hardcoded. E.g., see "<shift><control>I" when a new shortcut was added. There was also a shortcuts dialog added in July 2016 but it appears to show the shortcuts rather than let you edit them, and I'm not sure whether it made the cut into elementary's Epiphany.

So your best bet (without recompiling from source with your own fixes) is to use sudo apt install autokey, which adds an easy interface for mapping a new shortcut to the existing one. You can also set the keyboard "phrase" to only trigger within Epiphany. Here is GNOME's list of shortcuts.

Sync outlook calendar with the calendar app

Unfortunately I do not believe that is currently possible, Calendar doesn't currently support Exchange although there was some work on that in pantheon accounts, although I don't believe that works currently. Outlook supports publishing the calendar on a webdav server, however it does that without authentication which Calendar doesn't currently support, hopefully support for that can be added soon.

Relevant GitHub issues: Outlook support, Exchange support, ics sync, read only calendar support


Can i update ubuntu from 14.04 to 15.04?

It's Linux. So, there is always a way. However, I would personally recommend that you should not.
Why?
Freya is based on Ubuntu 14.04 (LTS), and you want to go to some unstable version, only for latest and unreliable software!
Wait a while. The next LTS version is coming soon, and you will soon get the next Elementary OS Loki!

Network and VPN consistently disconnect after locking screen for twenty minutes

These are the solutions that worked for me. I went into greater detail to explain myself and each solution.

I did quite a bit of research so I wanted to share this information with this group if someone else may find it to be helpful or useful.

GNOME 3.28 64 bit has a software flaw in which your desktop or notebook PC will go into suspend or sleep mode after you either lock your screen or leave it at idle for twenty minutes. This means that any GNU/Linux distribution or version that uses GNOME 3.28 64 bit is affected including the older Ubuntu 18.04.x 64 bit LTS, Red Hat Fedora Workstation 28 64 bit and others that use it as well. There are separate but related fixes for GNOME 3.28 64 bit and Elementary OS 5 "Juno" 64 bit that are closely related that will solve this problem. I am going to share the solution that worked for me for Elementary OS 5 "Juno" 64 bit GNU/Linux in this post.

To fix the problem with locking your screen that causes your Ethernet or 802.11 Wi-Fi to disconnect after twenty minutes, follow these instructions step by step:

1a. Open up the terminal
1b. Type in sudo -s
1c. Type in your root password
1d. Type in su -s /bin/bash lightdm
1e. Type in dbus-launch gsettings get org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type
1f. Type in dbus-launch gsettings get org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout
1g. Type in exit
1h. Type in exit again
1i. Type in exit once again to close the terminal

To fix the problem with your desktop or notebook PC going to sleep or suspend mode after twenty minutes:

2a. Open up the terminal
2b. Type in dbus-launch gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type nothing
2c. Put in your root password
2d. Type exit to close the terminal
2e. Restart your desktop or notebook PC for these changes to take into effect

To verify that these two important fixes do work, I own three gaming PCs: 1. mid-2017 AVA Direct, 2. mid-2017 ASUS ROG STRIX GL702ZC and 3. mid-2016 Acer Predator 17X (GX-791). Elementary OS 5 "Juno" 64 bit GNU/Linux is installed and updated on each gaming PC not to mention a healthy list of both free and open source and third-party closed source and proprietary software products. I decided to test these solutions by connecting to VPNSecure.Me to different VPN gateway servers in the United States of America and I locked my screens and I waited for thirty minutes. After that period of time elapsed, I unlocked my screens and I double checked to verify that my gaming PCs had not gone into sleep or suspend mode which they did not and that my VPN encrypted tunnels were still connected which they still are connected at this time.

Make sure to restart your desktop or notebook PCs after committing these changes in the terminal so that the changes take into effect after each PC restarts itself.


change font for io.elementary.terminal to cascadia code fails

Try setting it by directly editing the GSettings key:

(Or CascadiaCode or cascadia code: see the installed font name.)
Also check in the built-in Font Viewer that the font is installed correctly.


Unable to log in via GUI if you change GID and UID

My workaround above stopped working after a reboot. I think I found the issue...
/etc/adduser.conf defines the ranges:
FIRST_SYSTEM_UID=100
LAST_SYSTEM_UID=999

FIRST_SYSTEM_GID=100
LAST_SYSTEM_GID=999

# FIRST_[GU]ID to LAST_[GU]ID inclusive is the range of UIDs of dynamically
# allocated user accounts/groups.
FIRST_UID=1000
LAST_UID=59999

FIRST_GID=1000
LAST_GID=59999

It looks like the UI ignores UIDs/GUIs that are outside the non-system range.
It is only a problem for me because I am trying to match UID and GID with macOS (which uses the 500 range for users and 20 for "staff" group.

Is there a way to see changelog of update?

There currently is not, but there is already a filed feature request. At the moment, packages don't provide changelogs, so this would require both adding support in AppCenter for showing appstream release tag data and for apps to implement it


Reinstalling libglib2.0-0 will fix this error in my case.

sudo apt-get install --reinstall libglib2.0-0 libglib2.0-bin libglib2.0-data


The elementary OS is a distro based on a "long term support" (LTS) version of Ubuntu. This LTS versions only have packages with a stable status and strongly tested before the release.

That said, the version of wine at the moment of the release of current Ubuntu LTS, back in April 2014, was wine 1.6. The wine 1.8 was only released in December 2015, so it's not on Ubuntu yet and, therefore, not in elementary OS.

This is so that the distro has a more stable set of packages, at cost of fewer feature updates.

If you want to use the wine 1.8, or even the development version 1.9, you should install it via other sources, like a PPA or building it yourself.

Can't open a new tab or new file on scratch

This is due to a permissions bug that occurs when the first time you've run Scratch is as a privileged user. You end up with a directory in ~/.local/share/scratch-text-editor that you don't own.

To fix this issue:

Make sure you don't have any unsaved files in Scratch when run as root (with the sudo command). This fix will delete those files.
Open Terminal and use root permissions to remove the directory.

sudo rm -rf ~/.local/share/scratch-text-editor
Open Scratch as your own user (do not use the sudo command)

After this, you should no longer encounter the issue. In general, you should not run graphical applications using the sudo command since you can encounter these types of issues.


This is still happening as of November 14 with Firefox 82.0.3. There's a mozilla thread about it that indicates that it's an elementary-OS-specific issue and that it's a regression. They've been kicking the can down the road by marking the problem as "wontfix" for each successive Firefox version rather than addressing it. If this is specifically an elementary OS problem, can the underlying cause be fixed in the OS?


I guess "sudo apt install furiusisomount" did the job.


Can File Manager columns be added/edited?

No you can't.

I searched gsettings for list, and it does have a couple of options, but none for the top bar:

So I wondered if it was somewhere else, so I searched for the names of the

collunms, specificlally name and size. This gave the following:

org.gnome.nautilus.list-view default-visible-columns ['name', 'size', 'type', 'date_modified']
org.gnome.nautilus.list-view default-column-order ['name', 'size', 'type', 'date_modified']

So that shows that only nautilus allows customisation. If you need different information, you could consider installing nautilus.


Problem with Mediatek MT7630E and kernel 4.4

Mediatek MT7630E driver with kernel 4.4 support

In order to compile a new driver, you must open a terminal and execute:

sudo apt-get install --reinstall git linux-headers-$(uname -r) build-essential dkms

In elementary OS Freya you must install too the new gcc compiler. Open a terminal and write:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install g++-5

Now you can try to download the driver from the zip source at:

neurobin github.com

and unzipped it, or you just clone it with git in a terminal:

git clone https://github.com/neurobin/MT7630E.git

After download, you must enter in the new created folder. Open the file README.md and follow instructions to install the new driver.

Settings-Applications-Startup list versus ~/.config/autostart

There are different places from where stuff is autostarted. There are /etc/xdg/autostart and ~/.config/autostart that I know of.

All the stuff, that's not shown in the Startup list is in /etc/xdg/autostart probably.
And the apps that are in the settings list are probably in ~/.config/autostart

~/.config/autostart is for applications that only start on login of the current user, while the ones from etc/xdg/autostart are started for every one.


Can't uninstall Anything, how do I fix this?

So, I find out what to do. First I need to download the vivaldi .deb file from the official website and place it on my home folder. Them run:

dpkg -i vivaldi*

This will install vivaldi agian with the dependencies. Now you can remove it using:

apt-get remove vivaldi-preview


I had a similar problem but not as bad as yours.

Try the following commands in terminal:

$ sudo modprobe -r peaq_wmi

$ sudo modprobe -r eeepc_wmi


The easiest way is to use the graphics-drivers ppa.

You will have to run the following commands in the terminal:

sudo apt install software-properties-common

That will enable you to add ppa's to your repositories. After that you need to run:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update

After running the second command (or rebooting/waiting for the system to update repositories by itself), new drivers will appear in the AppCenter. You can install them there, or alternatively, you can install via terminal.

To find out which driver is the correct one, go to https://www.nvidia.co.uk/Download/index.aspx?lang=en-uk and select your graphics card. E.g. for Titan X (Pascal) it will show you (at time of this writing) the 418 series driver (version 418.56). Generaly you can obtain best results with the version shown. Do not download the driver from there, but rather install the appropriate version from the AppCenter, or in the terminal:

sudo apt install nvidia-driver-418

Reboot your computer, and you should be able to run the NVIDIA X Server Settings app, and your card should appear there correctly...

Note: You can try to install the driver from the Nvidia site, but you can also run into all sort of problems with that and if you are capable to get it working that way, you probably would not ask such questions here. You can also experiment with other driver versions, but you should make sure the relevant driver will support your card. With 1060Ti you can also try the newest 430 series, but that driver is still under development, so it may contain bugs and not be that stable - but on the other hand you may get better performance out of it... The best way how to test various drivers is to first uninstall the previous one and then install the new one. You should not have multiple driver versions installed at the same time.

How can I setup a printer with own ppd file?

elementary OS doesn't have an option like Ubuntu of loading directly from PPD. I would recommend instead downloading the driver directly from the manufacturer's website with their install script and following elementary's prompts.

If you would like to configure additional administrative features, run system-config-printer in your Terminal. Alternatively, you could try a CUPS web install or, if you are a glutton for punishment, CUPS install by text.


How to install wingpanel-slim or super-wingpanel on elementary 0.3 Freya (amd64)?

Both wingpanel-slim and super-wingpanel were developed and maintained by a developer on Launchpad called ~heathbar. Unfortunately, it looks like he abandonded both projects and did not update them to work with Freya (last change to wingpanel-slim was 2013-11-19, last change to super-wingpanel was 2014-03-04).

Therefore, sadly, there is (currently) no way to use one of those on Freya. Maybe development will be resumed by someone else, but at this very moment, it's simply not possible.

File selection with keyboard in file manager

You can hold control to select multiple files. (I believe this works in Windows as wel)
You can also use shift to select consecutive files, though you have to click the little tick at the top of the files.


Please follow these steps,

At first, go to System Settings and click Displays.
After that, click on the gear icon on the top-right side and select None from the drop down menu of Screen Rotation.
At the end, hit Apply and you are done.


help fixing winehq error : hera Release does not have a Release file

The problem is that you have an incorrect repository defined in your sorces list. There is no 'hera' distribution at https://dl.winehq.org/wine-builds/ubuntu/dists/; but there is a bionic one (elementary OS hera is based on Ubuntu 18.04 bionic)

What you'll have to do is to edit the /etc/apt/sources.list file and replace hera with bionic in the line that reads:

deb https://dl.winehq.org/wine-builds/ubuntu/ hera main

so that it becomes

deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main

You'll need sudo privileges for this: right-click the Files app -> New Window as Administrator -> navigate to /etc/apt -> open sources.list in Code -> carefully edit and save -> run sudo apt update to verify the changes.


One is from eos and the other is from Flatpak repository


I had many issues getting my GTX 750 Ti to run on my 21:9 monitor. Without the graphics card, the monitor worked. When I put the graphics card in with no drivers, it gave me a black screen. I installed drivers from the Software Center to get the display to work, but it only displayed at a 4:3 screen ratio. I tried to install proprietary drivers from the Xorg and the display did not work at all. So I took them off.  So how I was able to fix it was; I started with the non-proprietary drivers in and the GPU hooked up, then went to NVIDIA's website to download the files for the latest drivers supporting my card. Then I followed the steps on the following link to get the drivers properly installed:
https://askubuntu.com/questions/149206/how-to-install-nvidia-run

This worked for me with my Elementary OS. Hopefully it works for you too.

...

....

.....

Just a recap in step-by-step writing:

1) install "current version" of non-proprietary drivers

2) download files for latest NVIDIA drivers from their website (note the file path to the file)

3) plug in your graphics card

4) enter x terminal by pressing CTRL+ALT+F1

5) Follow the instruction in the following link:

https://askubuntu.com/questions/149206/how-to-install-nvidia-run

---Command should look something like:

sudo service lightdm stop

sudo init 3

cd [path/to/NVIDIA]

the HP Support Assistant seems not to be available for Linux.
Check https://www8.hp.com/de/de/campaigns/hpsupportassistant/hpsupport.html
and also https://h30434.www3.hp.com/t5/Notebook-Software-and-How-To-Questions/Support-assistant-for-linux/td-p/6718492

Do you need a special Driver for a Device like a Printer or a Bios Update? With BIOS Update there seems only the way to Install Windows and run it from there. Another Solution described here https://h30434.www3.hp.com/t5/Notebook-Operating-System-and-Recovery/How-do-I-update-the-BIOS-in-Linux/td-p/6498633 is to create a USB Bios Recovery Drive and Update it from there.


Mouse pointer stuck in drag mode when using Files and dragging-dropping

The solution is Alt+Tab to files app and then press Alt+F4 to close it. It releases the mouse pointer from drag mode successfully.

The question was originally solved in one of the answers to the question asked here.

It took me a while to discover how to unlock the situation, and not having to hard reboot to get out of it.


Mail (Geary): doesn't remember password, can't delete emails and can't start it with "--hidden"

You may need to enable "less secure" apps in your Gmail settings. See this answer and Google Accounts Help for more details.

I wouldn't be surprised if a future elementary OS release added Google OAuth login to online accounts, which would prevent users from having to do this. (That's of course 100% speculation, but I still hope it happens! )

How can I access "legacy" indicators in Elementary?

Incompatibility between third-party apps and Wingpanel is something that elementary can do little about, as it is third-party devs' job to provide this kind of support. In fact, there has been a lot of talk about moving away from Ayatana indicators for future releases. (see this blueprint for example).

As for the Dropbox indicator, several workarounds have been provided. Search the questions here on StackExchange. What worked for me is this script.


macbook hardware specs INCLUDING battery

You should be able to get some additional information about the battery in your system with the following command in the terminal:

upower -i /org/freedesktop/UPower/devices/battery_BAT0

However, you may be better using something like iFixit's "Identify my Mac" page to get the exact model, and it's also a fairly reputable place to buy replacement batteries from.


Some HTTPS websites give an error with Midori. Why is this?

This is a problem with glib-networking related to certain types of SSL certificates. It should be fixed in the next release of elementary OS or if we can determine that it is safe to update this package.

You can reach elementary.io through http instead of https. Just make sure to remove the "s" from the URL :)


Press the ESC key while on the elementary OS logo. This should work on some computers


Epiphany internal PDF viewer just flickers

There is a button you can use to download it, but the button is part of the internal PDF viewer, so I assume you're unable to use it.

I can guarantee this won't be fixed because nobody has reported a bug. First step would be a bug report on gitlab.gnome.org.


"No detected operating systems" - What should I do?

I thought the same and apparently is because you are trying to install EFI and UEFI, test mode (if your BIOS permits) in LEGACY mode.
Luck!


Does upgrading elementary OS Freya (0.3) result in 0.3.1?

The kind of harsh but true answer is that you will never have the same exact thing as a clean install no matter OS you upgrade. There will always be some minor (and sometimes some major) differences, especially when the new version changes any default configuration files.

Specifically regarding the new hardware enablement stack, this is not pulled down automatically. While theoretically everyone should experience better results, it's possible that the new hardware stack will give certain setups worse results. If you're not experiencing any issues with your hardware, you should probably remain on the 0.3.0 (Trusty-based) stack.

If you need help upgrading to the new hardware stack from 0.3.0, please see this post

iMac and rEFInd: black screen after installation

ATI Radeon Mobility 4670 + iMac? Forget about Linux working properly, just use a VM in specific cases or think about getting another computer.

Also, you can press F2 in rEFInd and  write radeon.modeset=0 if you really want to use it, but it's better not.

It's my desktop PC (unless I am on a late 2009), and it's resolved in AskUbuntu in my question of the same issue.

Also, I like rEFInd, but it's not mandatory.


Searching a little i found that this is a common bug and devs are working to fix : https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1561278

I think you should try to update alsa to latest version

But i don't think will fix


Superuser/root password does not match user password

According the Ubuntu documentation, you can reset your root password following these steps:

Boot your system and hold shift key pressed until you can see the GRUB screen.

Use your arrow keys to go to an option marked as "elementary OS, linux...  Recovery mode". Hit enter.

You must see a new screen with some options.  Select the option marked as "root". You will be prompted to  a bash screen where you can see something like:

root@freya:-$

You must make your filesystem writable with the next command:

mount -rw -o remount /

Now you can change your password with the command:

passwd username

Where username is your current user. You must enter the new password twice.

After this, you can continue with normal boot with the command:

init 2

Ubuntu documentation


This is the same with my problem, my laptop is Dell Vostro 1440, when i press WIN + L (lock the computer), after that when i login the cursor will disappear.
I look for this problem and this is the way to fix it but when i logout and login again, i will have the missing cursor again:

gsettings set org.gnome.settings-daemon.plugins.cursor active false
gsettings set org.gnome.settings-daemon.plugins.cursor active true


It's a well-known bug on Freya.

I couldn't fix that, but pressing CTRL+ALT+F1 (you enter the CLI interface) and then CTRL+ALT+F7 (to enter again the GUI) helps.

The problem with cursor appears also after locking and hibernating my computer.

I recommend Loki - I didn't experience any bugs like that. :)


Missing styles when building app using Gtk.CssProvider

I was able to find my own answer.

What I needed to do was install it in CMakeLists.txt

# install css
INSTALL(FILES src/style.css DESTINATION ${PKGDATADIR})

Then in the vala file I needed to call it where the destination would be:

try {
    css_provider.load_from_path(DESTINATION + "/style.css");
  } catch (GLib.Error e) {
    stderr.printf("%s", e.message);
  }

DESTINATION should be the location in the directory where you are saving the file. This can be done by assigning variables or hardcoding it.


To my knowledge, Secure Boot will not allow you to boot a Live USB. And to boot Elementary in Secure Boot after install, you need to set your BIOS Secure Boot option to SETUP MODE. This way, Elementary will be added as Authorized automatically and it will boot. Just worked for me. Check it out and let me know.


How I solve it :

I read only my GTX 1050 is not compatible with ubuntu without a driver.

So :

I during boot I click "e" Button and I wrote after quiet splash This :

  nouveau.modeset=0

after that, I install Elementary os as normal.

For the first start-up, I use just put nouveau.modeset=0 on the boot screen

after I went to the software center and I install Nvidia Drivers.

now Elementary os Works fine.


I have found a similar (may be exact) bug here ibus/+bug.

Removing the /home/[user]/.config/ibus/bus solve the problem.

If still not solved, remove the ibus-unikey

sudo apt-get remove ibus-unikey

Also from comments you used sudo add-apt-repository ppa:ubuntu-vn/ppa so you may get errors while running apt-get update So remove it by

sudo add-apt-repository --remove ppa:ubuntu-vn/ppa
sudo apt-get update

You can install ibus-unikey by the command:

sudo apt-get install ibus-unikey


Possible to combine top panel bar and dock?

As far I know, no. You can change the position of this dock using elementary-tweaks, but if you move it on the top, it will go under the top panel which is not really convenient, because you barely can click items.


According to Wiki, your user must be part of the "autologin" group.

sudo groupadd -r autologin
sudo gpasswd -a sdwhwk autologin


I've encountered the same issue.
I deleted contain of /etc/apt/sources.list.d/ directory by mistake.

Add a file into /etc/apt/sources.list.d/ as named appcenter.list.

Insert the line below into the file that's been created newly:

deb http://packages.elementary.io/appcenter xenial main

then try again:

sudo apt-get update
sudo apt-get install appcenter

I overcame the issue by this way.


USB devices not detected if connected on the fly

Before Edit:Has your problem been solved. I am facing the same issue! This is in addition to printing and screen issues (Running Loki on Asus UX305 (Dual Boot option). Out of the box, the notebook came with windows 10 home). But this one seems to be a deal breaker.

To detect the device, I have to do either of the folowing: a) suspend the system and wake it up (b) turn off the computer and restart. This issue is observed whether I use the USB-3 or USB-2 ports.

Opera is working fine

I just used snap to install it and here you can see the main window

https://snapcraft.io/opera

Now if I disable the sidebar in settings

This is the APT version of Opera, same images

To install it through APT just:

$ wget -qO- https://deb.opera.com/archive.key | sudo apt-key add -
$ sudo add-apt-repository 'deb https://deb.opera.com/opera-stable/ stable non-free'
$ sudo apt-get install opera-stable

https://deb.opera.com/manual.html

(current add-apt-repository run and update after you add a repo, so you need to add the key first)

Maybe your problem is that you have residual settings in your /home?


This is a reported bug. And a fix was recently approved.

The solution to your problem seems to be to wait for an update. :)


What is "Pressure Reveal" in dock preferences?

Pressure reveal is a feature designed to make it harder to accidentally un-hide the dock. Instead of revealing any time the cursor hits the bottom row of pixels on your display, it reveals when you continue to push your cursor past the bottom row of pixels on your display. In this way, it should still be easy to reveal the dock when you actually intend to do so, but harder to accidentally reveal it when you don't intend to.

At the moment, this feature is optional because it doesn't fully cooperate with input devices where you can't push the cursor past the bottom of the display: stuff like drawing tablets.


Can I get bluetooth devices to remain after suspend/resume and/or reboot

To enable bluetooth on every startup you need to add your custom command in etc/rc.local

Open terminal and type

sudo nano /etc/rc.local

Now add the following line before exit 0

rfkill unblock bluetooth

It will start bluetooth on every startup.


50% CPU usage on idle, 100% CPU usage as soon as I open a window

Thanks for the info.
I tried a few linux distribution with different desktops.
Here are the results.
In Linux mint with xfce  the windows move very slow and keep moving even if I let the mouse button go. Wit the option of hiding windows content while moving them, it works fine.
I also tried debian. XFce is the same.
Openbox is also not working. Windows move slow and keep moving if I let the mouse button go. Openbox has no option for hiding windos content while a window is moved, so openbox does not work for me.
I also tried the Mate desktop. To my surprise it works better than Openbox. When I enable window compositing it works the best. That is really a surprise. I think the limitation on this machine is not memory but cpu usage.
So I ended up with debian Mate and windows compositing.
It looks like it is a bit lighter than Linux mint.
I can even play DVD's it only starts chopping when I touch the mouse.

What is surprising to me is that elementary Os is heavier on cpu than Linux Mint and Debian while it is supposed to be light weight!


Make pantheon terminal window appear on all workspaces

You can achieve this by assigning a keyboard shortcut to "Toggle on all Workspaces" in System Settings -> Keyboard. Now when pressing that keyboard combination with your Pantheon Terminal active, the terminal window should appear on all workspaces. Press that same combination again, and the option should get disabled.


Can't change elementary OS resolution on Virtual Box

Solved this just now on a Mac host in Virtualbox 5.0.8 by
in terminal for host:
VBoxManage setextradata global GUI/MaxGuestResolution any

and then in terminal for guest:  all the steps set out at
 install-virtualbox-guest-additions-elementary-os.

required some small experience with using the terminal, reading the text to understand what it was telling me to do about installing dependencies and removing unneeded or broken things.

sudo apt-get update

and

sudo apt-get autoremove

got used a lot, probably more than necessary.

Once I did that, screen sizes are available.

Then I went to the Files window and tried to change from icons to list and everything froze and I had to power cycle the VM, but it seems to still work after restarting it.


Elementary OS 5.1 Hera (based Ubuntu 18.04) automatic logout session occasionally

Same. I am thinking about migration to another linux dist, cause this error is really annoying. I work on ElementaryOS and during my workday (8 hours) system can logout something around 2-3 times. I am preety sure this problem has appeared after last update - 5.1.


Will there be an automatic update function integrated in the final version of elementary OS 6?

Automatic updates would be cool! This feature doesn't appear to be planned for elementary OS 6, but it could be added in the future.
There is a GitHub issue for automatic updates and another issue for automatic security updates. That said, this feature doesn't appear to be in development, and there's no mention of such a feature in this elementary OS 6 update.
The good news is that there are bounties on both of those issues, and the elementary OS team does seem to be in favor of implementing automatic updates.


How can I get my hardware working in Elementary?

Missing panels in Switchboard doesn't really have anything to do with hardware. Most likely, you've installed some third party software, possibly from a third party PPA that conflicts with Switchboard.

You'll need to reinstall the missing switchboard-plug-gcc-* packages from Terminal. For example, for sound:

sudo apt install switchboard-plug-gcc-sound

You can use tab to auto-complete in Terminal to discover the names of other plugs to install.


From screenshot it is clear you have four primary partitions.

Refer Disk partitioning:

  The total data storage space of a PC HDD can contain at most four primary partitions, or alternatively three primary partitions and an extended partition.

To rectify this, you would need to remove a partition, replace it with an Extended Partition, then use logical partitions within that Extended Partition to get more than 4 partitions onto the drive.


How to migrate all packages to elementary OS

You can use the tool "apt-clone" for this.
http://manpages.ubuntu.com/manpages/yakkety/man8/apt-clone.8.html

But i would recommend to start fresh and install only those packages you currently use..


AppCenter complains and doesn't work to install anything

So the solution was pretty simple.  Just a matter of removing AppCenter:

sudo apt remove appcenter

and then reinstalling it

sudo apt install appcenter

Et viola, no more errors!  I think it had something to do with reusing a /home partition from a previous elementary OS (and a few other distros too) install.


How do I access files in my Windows Documents folder?

For the OSes to share common folders, you have to edit the fstab file to mount the Windows partition on boot, then change your default documents folder location.

Mount Windows partition on boot

This steps are taken from this answer which also list terminal-only instructions. Here i will just copy the visual way of doing it, for easy access.

Since the answer was for ubuntu, you have to install the Disks application fist, cause elementaryOS does not come with it.

Open the terminal and run this command to install it:

  sudo apt install gnome-disk-utility

Once opened, on its main window, "Disks" graphically shows you your current partition layout.
Now simply choose the NTFS partition of windows that you want to automatically mount on boot, then click on the small gears icon slightly below it. From the menu choose:

  ‘Edit Mount Options…’

From the next window that is shown, move the slider button to the left, next to the ‘Automatic Mount Options’ label, to gain access to the settings. Keep the check-marked option ‘Mount at startup’. Select/Fill the next four options if you wish, like "Mount Point". For example:

  "/home/$Luser/windows/"

Note: $Luser is your elementaryOS user.

Now reboot.

Changing the Documents folder

The locations of every user directory are in "~/.config/user-dirs.dirs".
Open this file in scratch:

  scratch-text-editor ~/.config/user-dirs.dirs

Search for this line in the file:

  XDG_DOCUMENTS_DIR="$HOME/Documents"

Replace "$HOME/Documents" with the path to the Windows Documents folder. So it would be somehing like this:

  XDG_DOCUMENTS_DIR="/home/$Luser/Windows/Users/$Wuser/Documents"

Note: $Wuser is your windows user.

Now just copy all your files in your old documents folder to the new one, then reboot.


how can i create and use multiple terminal configurations simultaneously?

I believe it is not possible, in current version of pantheon-terminal, to have multiple "user profiles", what I believe is the "preferences" you're asking.

If you really need it, a good option is the gnome-terminal that have this feature. (and it's written in gtk so it doesn't look too diferent from the rest of elementary OS)

Just install via

sudo apt-get install gnome-terminal -y

Change your preferences in Edit > Profile Preferences menu. Save multiple preferences in Edit > Profiles...

If you want to use it as the default terminal, run

sudo update-alternative --config x-terminal-emulator

and select it from the list.


Firefox "Reader View" introduces static to my sound

I had this issue on (K)ubuntu 16.04.1 - there seems to be a problem with HDMI for some sound drivers. (I have a Radeon HD 7970 series sound card.)

The first solution here worked for me:
https://askubuntu.com/questions/405071/static-and-crackling-in-my-hdmi-audio

From this discussion https://bbs.archlinux.org/viewtopic.php?id=116172 comes an explanation of the setting:

  tsched=0 disables PulseAudio's timer-based scheduling and uses the classic interrupt-driven approach. Timer-based scheduling allows for better latency management and reduced CPU usage. It puts very strict requirements on the ALSA drivers. Unfortunately, some drivers do not handle it well.

I suspect the problem is immediately caused by the text-to-speech module in Firefox Reader View but not sure how.


This guide helped in my case: https://connectwww.com/how-to-solve-realtek-rtl8723be-weak-wifi-signal-problem-in-ubuntu/4625/

My problem was that my wifi card had 2 antennae but only one was plugged in and the linux drivers were using the wrong one. This downloads new drivers and changes the ant_sel option to 2.

git clone https://github.com/lwfinger/rtlwifi_new
cd rtlwifi_new
sudo make install
sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=2

If it doesn't solve the problem, try with sudo modprobe -v rtl8723be ant_sel=1.

If the problem was resolved, then use this command to make the change permanent across reboots:

echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/50-rtl8723be.conf

(or ant_sel=1, as the case may be).

Be aware that some updates replace the above configuration and so you might have to change this periodically. I made a bash script in my home with the above commands (minus the git clone part, of course) and run it when I see that the internet is unbearable slow.

Also, you might want to try disabling bluetooth. For some reason my laptop cannot connect on the internet if BT is enabled.


Well, you are right, they do not permit to download the old version from the official site.
Anyway, here is the sourceForge link.

How can I change the location of my Personal folders?

Symlinks might be what you are looking for.

Delete (or rename if you want to keep the files within) ~/Downloads folder.
In terminal type out the equivalent of:

ln -s /media/Documents/Documents/Downloads /home/pablo/

This would create a link to your windowsdrive, such that when you use your ~/Downloads folder it would be as using /med../Downloads.

Very handy thing with config files etc. and for example Dropbox, for creating a kind of sync between all your computers.

This would not "Change the location" of the folders. But it would change where the data you altered in these folders would be saved. I think this is essentially what you are after.


Elementary OS Juno - No sound on USB-C monitor

GDog was correct, installing pavucontol is the workaround to this issue for now, Hopefully the Elementary team fixes this in the future!

done.

Thanks GDog!


You can use this:

How to add 1920x1080 Display option and make it survive restart

I now have an answer to my own question. Being new to Linux I am still in the initial learning phase so I made a silly error. The first two code for "xranr newmode" & "xrandr addmode" are correct but I needed to create a new.sh file in  /etc/profile.d/
sudo gedit /etc/profile.d/external_monitor_resol.sh

into which the above newmode & addmode code is entered and the resulting file saved. In the end I now have 1920x1080 as an option in Displays and it survives restarts and shut downs.


Your dpkg (package manager) can't read the listing file, required to install the 'language-pack-uk-base' package because of input/output error. Possible cause:
file system corruption. You can try solutions suggested here, or check your unmounted system partition with fsck from a bootable USB drive.


I was able to replicate your issue.  I am able to start the program from the command line:

mono /usr/share/ssm/Screenshot\ Monitor.exe

This will work as well:

mono '/usr/share/ssm/Screenshot Monitor.exe'

A Log In window appeared.

But I'm not sure why it won't start by clicking on the icon.

I installed it in Ubuntu and it works just fine. You can launch it from the icon. I didn't notice any differences in the respective .desktop files in Ubuntu and elementary OS.

What are the effects of a custom kernel?

elementary OS disappeared. What should I do to prevent this again?

OK, so the problem is with GRUB. It didn't installed properly during the installation.

Why can't you see Linux partitions inside of Windows?

Windows does not support ext4 out of the box. ext4 is the most popular file system for Linux. However, you can see your partitions by installing some third party software (not gonna suggest one of them, but you have plenty of choices).

What's GRUB?

Basically it's the most popular boot selector that supports Linux. When you install Windows, it installs a small partition called Windows Reserved that it uses as a boot loader and boots you directly inside of Windows. GRUB creates another small partition (250 MB I think) where you can see all of your operating systems and lets you select which one you want to boot into.

Where's the problem?

The problem was that you haven't installed GRUB properly. I'm not sure about the automatic "Install elementary OS alongside Windows" option, however, if you select Something else during the partitioning process, you'll see something like this:

I'm not going to talk about the upper part of the window because that's an answer to some other question. What I am going to talk about is that bottom part that says Device for boot loader installation. What you should do here is to select your default hard drive and elementary OS should figure out the rest for itself.

Is it safe to remove all these packages?

What did you do last?

This can happen when you remove a 32-bit package on a 64-bit system.After that the system does not need these libraries and will add them to autoremove.

If it is that then safely remove (but create a system snapshot before so you can restore if anything breaks)

EOS updates causes compiled gvim to get replaced with vim from packages

This was happening because the version of vim in the repos is 2:7.4.1689 while checkinstall was using the date-time string as the version by default 20161021. Thus, the version in the repos was considered as newer (Vim 7.4) and was trying to upgrade the older (Vim 8) package.

This was fixed by explicitly specifying the version in checkinstall as 2:8.0.46

How to install drivers for TP LINK WN822N v4 Wireless USB Adapter?

This adapter is compatible with the rtl8192eu driver, you can install it with the following commands:

sudo apt update
sudo apt install git
git clone https://github.com/jeremyb31/rtl8192eu-linux-driver
cd rtl8192eu-linux-driver
make
sudo make install
sudo modprobe 8192eu


It would be a good idea to install the latest MESA drivers, you could add the official repositories

sudo add-apt-repository ppa:ubuntu-x-swat/updates
sudo apt update
sudo apt dist-upgrade

They work very well in my case, even in games.

When booting up your system (be sure to plug in your ISO USB before booting) you should see a BIOS screen indicating what keyboard button to press to get into the Boot Options, in my case it's F12. From there you should be able to choose to boot into the USB Drive to run from the ISO & give Ubuntu a try. You may have to run your system setup from the BIOS screen (in my case it's F2) to change some settings if you don't see USB as a boot option. These keyboard shortcuts can vary based on computer & hardware manufacturer. I have another laptop that uses the ESC key & other keyboard shortcuts to access the BIOS. Let me know if this helps & if you need further guidance.


That is because of snap version ...I don't have it also but I use Ubuntu 20.04 LTS...with normal version of firefox no problems at all...


Flickering when I log in even though I have the same wallpaper before and after logging in

I suspect it is because login screen (greeter) and the desktop environment are a bit different entities. Lightdm starts the greeter, but desktop is handled by another entity, pantheon. They use same image only because system configures both at the same time when you change it.


New elementary OS install boots to terminal

May not necessarily be your issue; but I had this issue with Luna while back on my laptop - the graphics driver was not installed, I had to manually install it.

This guide may help:

Alright so turns out it is just granite and that package names are listed in parenthesis on valadoc.org when you search for Granite(granite). I do wish it was more clear on the github page how to do this though. I only found it by looking at another project that was using it.


PRINTER HP 3070A HPLIP VERSION NOT SUPPORTED

If it's supported in Ubuntu 16.04, it's also supported on eOS Loki. I had a similar problem with a HP printer. When you first plug it in, you have to select it from a list. The names are approximate. I have a Deskjet Ink Advantage 3785. When I selected from the Ink Advantage series it didn't work, I had to select it from the Deskjet 3700 series. So try reinstalling it with a different series.


NOTE: The following may delete apps or change settings of programs that you've already installed. Make sure to have a backup of the important files.
Open a Terminal and execute the following:

First delete all nvidia drivers with sudo apt autoremove nvidia*

Then install the correct driver for your system with sudo ubuntu-drivers autoinstall

If any of this breaks your desktop, you can install it with sudo apt install elementary-desktop


Has anyone installed Nordvpn in elementary OS 5, if so how?

Please download the version of nordvpn and open a terminal window pressing Ctrl+Alt+T and execute the following commands,

cd ~/Downloads
sudo apt-get install ./nordvpn-release_1.0.0_all.deb
sudo apt-get update

Please note that we are changing directory to "Downloads" because this is where the downloaded files are stored by default and we will have to execute the two following commands from where the file is saved. If you manually saved the norvpn file somewhere else, please change working directory to that directory instead. For example, cd <some_other_dir>.


Ok, have got fingerprint authentication working now in Hera 5.1, with the Thinkpad X1. Maybe others will be luckier than me, but following the instructions on https://github.com/3v1n0/libfprint did not work for me. I tried many variations, but always the same error with fingerprint-gui and fprint-demo: No Device Found.
While this method works, it will not work with either of those GUI applications.
Huge thanks to sysadmin here, @himekifee over on Gitter, and Marco Trevisan for his work on all this.
Here are the steps to get things working.
Install snap:
sudo apt-get install snapd

Install Validity tools and initialise the device:
sudo snap install validity-sensors-tools
sudo snap connect validity-sensors-tools:raw-usb
sudo snap connect validity-sensors-tools:hardware-observe
sudo validity-sensors-tools.initializer

Compile libfprint:
git clone https://github.com/3v1n0/libfprint
meson libfprint libfprint/_build && sudo ninja -C libfprint/_build install

Install libfprint
Install fprintd
Install fprintd from focal release 20.04: (the bionic version would not work)
echo 'deb http://archive.ubuntu.com/ubuntu focal main restricted universe deb-src http://archive.ubuntu.com/ubuntu focal main restricted universe' | sudo tee /etc/apt/sources.list.d/ubuntu-focal.list

echo 'APT::Default-Release "bionic"' | sudo tee /etc/apt/apt.conf.d/01ubuntu-bionic

sudo apt-get install -y -t focal fprintd

Install PAM:
sudo apt-get install libpam0g-dev libpam-fprintd

Configure PAM:
sudo pam-auth-update

Include fingerprint reader as authentication option. Click ok.
Update symbolic link /usr/lib/libfprint.so.0 -> /usr/local/lib/libfprint.so.0.0.0 (to libfprint)

Allow fingerprint enrolling to user:
Create /lib/udev/rules.d/40-libfprint0-custom.rules as follows:
ATTRS{idVendor}=="138a", ATTRS{idProduct}=="0090", MODE="0664", GROUP="plugdev"

**Add your $USER to plugdev group:**

usermod -a -G plugdev $USER

Reboot
Enroll fingerprints:
fprintd-enroll

Verify fingerprint matching:
fprintd-verify

Add fingerprint authentication configuration for login:
Edit /etc/pam.d/common-auth for editing (sudo nano /etc/pam.d/common-auth).
Add: first line
auth    [success=2 default=ignore]  pam_fprintd.so max_tries=1 timeout=10
auth    [success=1 default=ignore]  pam_unix.so nullok_secure

Can also edit /etc/pam.d/sudo (include at the top):
auth    sufficient  pam_unix.so try_first_pass likeauth nullok
auth    sufficient  pam_fprintd.so

In Loki, nimf is perfect for Korean Input Method.
1) $ sudo apt install nimf
2) $ im-config -n nimf
3) Log out & Log in

Now, you need to go nimf-settings on the wingpanel or
run this command in terminal
$ nimf-settings

deactivate those two button "anthy" and "sunpinyin" for input method unless you are using Japanese , and Chinese

and now you need to set Key combination follow by your behaviour
in "libhangul", it is set Hagnul & Hanja key as default key to input Korean & Chinese character for Korean,
I usually use Hangul with Shift + Space for Hangul

If it doesn't work for you , try to change your keyboard layout to Korean or Korean (101/104)


Can I swap the close buttons from the left to the right?

Here is another approach without installing any additional software.
Open a terminal session and run one of the following commands:

Default Button Style

gsettings set org.pantheon.desktop.gala.appearance button-layout close:maximize

Max and Close buttons switched

gsettings set org.pantheon.desktop.gala.appearance button-layout maximize:close

Windows Button Style

gsettings set org.pantheon.desktop.gala.appearance button-layout :minimize,maximize,close

Mac OS X Button Style

gsettings set org.pantheon.desktop.gala.appearance button-layout close,minimize,maximize

You have to logout and login or restart to make the changes take effect.


How can I add multiple timezones to loki?

The new datetime indicator doesn't have this feature yet.


How can I get Thunderbird to work with the messaging menu?

Note: The follwing instructions valid when you loginto your mail via thunderbird. Also this is the normal(default) behavior for thunderbird (also for geary). See note 2.

Instructions:

Open Thunderbird.

Enable the "Messaging Menu ...." and restart.

If you got any message,  the panel icon shows blue dot, like:

Note 2:

AFAIK, thunderbird does not have a background service that will fetch mails and show indicator. You have to loginto your mail to get notifications.


How can I restore the Files app to original settings?

To restore Files original settings you can run sudo apt purge pantheon-files to remove most of the Files configuration files. It will not remove those in your home directory that were created by running the program such as your bookmarks or color tag database but you probably want to keep those. Then reinstall it with sudo apt install pantheon-files (after doing sudo apt update to make sure you get the latest released version).

However, I fear from your description that you have deleted a lot of unrelated files as well which cannot simply be restored unless you have a backup of your home folder.

To restore the whole system default settings open Switchboard and navigate to the "About" plug.  There is a button "Restore Default Settings". Again, this may not work if important files have been deleted.


Updating Hera: Expected bionic but got trusty

1. backup your sources.list
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
2. change repos to bionic
sudoedit /etc/apt/sources.list and replace trusty with bionic. Probably some source lines are not the same for trusty and bionic so if you  still have errors for them you better remove these repositories from your sources list, the safest way is by putting a # in front of each line.


Note - This is not a solution to your problem, rather a way to get Chrome working.

I faced similar issue and just to save some time and effort, looked for Chromium in the new app store. Turns out you have one! The chromium in the new app store is at version 52 and works perfectly fine, without the need to use gdebi, apt-get install, etc.

If you aren't hell bent on installing Google Chrome (the .deb from their webpage) then Chromium (open source) works just fine! I have been using it since installing Loki and no problem whatsoever :)
