The comment by @KGIII helped me move along in the right direction. I am thankful for the help. It seems that the hanging problem was due to the "cryptsetup" package failing on dependencies. Very strange that AppCenter and its associated processes did not have permissions to overwrite files. I was required to use the "--force-overwrite" option and used "dpkg" to manually fix the issue. Of course, all of this was done by dropping to the command prompt to be able to view the messages. Perhaps they were also written to a log but I did not check.


Minecraft is havinng size problems in elemenry os

I solved the problem.
If you do play Minecraft, the launcher for the game has an issue with it's window shadow. This can be fixed easily. Type in this command in terminal:
sudo nano /usr/share/applications/minecraft-launcher.desktop

find line "Exec"

and add: env GTK_CSD=0

save file and lunch minecraft


How to display folder size in file explorer?

The devs should correct me, but I don't think this is possible. I think you will have to file a bug report on launchpad.

The reason will probably be that it requires a lot of disk reading to find the disk usage of everey directory. For an extreme example opening /: It will have to recursively read the entire filesystem.


Elementary OS Juno and Windows 10 dualboot time is wrong. RTC time is not changing to local

Please execute this in your terminal,

timedatectl set-local-rtc 1 --adjust-system-clock

Do not worry if you see a warning after running timedatectl.


You need to create a .desktop file and put it inside ~/.local/share/applications.
To do that open any text editor and modify the following code to make it work with your app. Please modify the Exec= line with the correct command to launch the app. You can add an icon as well, for that you need to save the file somewhere and add the full path.
Save the following as caja.desktop
[Desktop Entry]
Type=Application
Name='Caja File Manager'
Comment='Open the file explorer'
Exec='caja'
Icon=''

I finally achieved this using the wmctrl command.

sudo apt-get install wmctrl

wmctrl -d

gave me output:

How to install Scratch Text Editor in Ubuntu 16.04

I don't know, this is an elementary forum, not Ubuntu. j/k! I'm sure you could build it from source (https://launchpad.net/scratch) but it's really just a fork of Gedit. You can find that in the repositories in Ubuntu and it should work just as well for you. Besides Scratch might look funny in Unity due to it's client-side decorations.


Finally the best way to solve this problem is installing Nvidia Graphics driver and choose Intel Graphics device in Nvidia X Server Panel. After reboot, now I can shutdown and reboot my laptop normally.


Strange behavior with ctrl + shift + e shortcut

I guess I found solution:

export GTK_IM_MODULE="gtk-im-context-simple"

and then run vscode (or another app) from the same shell.
If that doesnt work try this:
export GTK_IM_MODULE="xim"

As for me second variant works well.

To save this for all application put line into /etc/environment, or per-user in ~/.gnomerc.
(The export command doesn't go in those files, just a new line with GTK_IM_MODULE="xim" or GTK_IM_MODULE="gtk-im-context-simple".)

How heavy is elementary over classic ubuntu?

"additional apps pre-installed" implies that original Ubuntu and Gnome apps are present. Except where no alternative is available, they are not. We don't ship with both the Unity and Pantheon desktop installed, just Pantheon.

The current recommended system specifications are as follows:

Intel i3 or comparable dual-core 64-bit processor
1 GB of system memory (RAM)
15 GB of disk space
Internet access

Without these basics your installation will suffer. That said, Loki (I believe) will turn-off animations to degrade the experience, but improve the performance, of the system once it is release.


Solution to make all videos properly work in Epyphany

I suspect the other videos require the media source extensions API (MSE) in order for you to receive high-quality videos. WebKitGTK+, the web engine powering Epiphany, requires GStreamer 1.14.4 to enable MSE, but unfortunately elementary has an older version of GStreamer and is unlikely update it since it's part of the base system inherited from Ubuntu. Most likely you're out of luck until the next version of elementary based on Ubuntu 20.04 is released, sorry.

How to fix borders in Elementary's file manager?

I had a fresh install of Elementary OS, so I installed nautilus through the app center and what I noticed is that it added a second app icon in the applications menu called Files. One of the two is the correct, desired file manager you wanting and the other is nautilus.

Have you tried simply uninstalling nautilus again? If you cannot uninstall nautilus through the appcenter, then you can uninstall it through the terminal by issuing the following command:

sudo apt-get remove nautilus

I hope this helps.


Can I "convert" a Ubuntu installation to an elementary installation?

You could install the elementary desktop and all the standard applications on top of your existing Unity desktop with these commands:

sudo add-apt-repository ppa:elementary-os/stable
sudo add-apt-repository ppa:elementary-os/os-patches
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install elementary-desktop

You'll probably have to logout and switch to Pantheon in your display manager.


Can i install Broadcom wifi driver offline?

The output of lsusb is not enough to understand the exact model of the wifi card. For more details try

pdfshuffler:

Looks like there is bug report about pdfshuffler on freya :

Launchpad Bug Report

As for the error you are getting :

Gtk-Message: Failed to load module "pantheon-filechooser-module"

A bug report was filed and fixed. pantheon-filechooser-module-bug-report

You might have installed an older version of the application.
Try re-installing the application, but from this link:

pdfshuffler for ubuntu 14.04

Download the package according to your system architecture.

According to this post the user is having a similar problem with a different application, and updating the application to the latest one fixes the problem.

Now, if you are getting an error about not finding a package named poppler:

You need to install poppler python bindings, which will be pypoppler and pypdf(recently changed to pypdf2).

Ohh, and also remember, not to run pdfshuffler as root.

Reffer to these if you want a detailed answer to the poppler problem.

poppler not found solved

could not import pdfshuffler debian bug report

For a different approach to this problem, check if you are getting this error:

Gtk-Message: Failed to load module "canberra-gtk-module"

If you are, then you may find help here: failed to load cranberra-gtk-module

or here : cranberra-gtk-module solved

Now, for the other part of the problem,
radio tray:

I hope you will find help in either of these links. Both show how to make radio tray work in elementary:

or

Hope these links might help you find what you need.

What partitions should I create during installation with legacy bios specification?

For legacy BIOS mode, the very first partition should be a 1 MiB Reserved BIOS boot area.
You have a couple of considerations regarding other partitions.
If you want to encrypt your root filesystem, you need a separate, unencrypted /boot partition.
If you want hibernation, also known as suspend-to-disk, then I recommend a swap partition with at least as much disk space as RAM.
I also recommend that this be encrypted, but that gets a bit more complicated.

There is a PPA for GHC and Cabal, you should check if it is what you need:

https://launchpad.net/~hvr/+archive/ubuntu/ghc

You can add this to your system with

sudo add-apt-repository ppa:hvr/ghc
sudo apt-get update

Or you can install the generic Linux version if you need to use a more recent version of the full Haskell Platform. However this does not take advantage of the elementary OS package system.

0.10.6-1~ubuntu16.04.2
0.9.4-1ubuntu3
0.9.4-1

I would suggest trying to install the latest ones first but installing very old packages might break other packages you have installed in your system.

If all of the packages above have failed, either the issue in upstream Ubuntu hasn't been resolved yet or there are core packages that have incompatibilities with gnome-software-center. If that's the case, you might have to live without gnome-software-center for now until the package maintainers release a fix. (Elementary's default AppCenter is a nice alternative)


How can I have the same applications in the Dock for the Guest session as I have in the Administrator account?

You can customize your guest session under elementary OS. In your case you might only want to copy some of the configuration files of your Administrator account (startup apps, dock apps, etc.) to /etc/guest-session/skel that will be copied for each new guest login.

The customization steps for elementary OS are pretty much the same as for Ubuntu: https://help.ubuntu.com/community/CustomizeGuestSession.

Part of the original tutorial: 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.


You no need to run the script at startup each time you can permanently set resolution like this:

sudo xrandr --output HDMI-1 --mode 2560x1140

You can get list of your display by running:

xrandr -q

Just make sure the resolution you're trying to set is supported by your monitor.


(SOLVED) How to enable HiDPI scaling in the pantheon greeter?

Finally, after all this waiting I found a quite good solution for this problem:

sudo nano /usr/share/glib-2.0/schemas/org.gnome.desktop.interface.gschema.xml

Change the default value to 2 (or your desired scale factor):

<key name="scaling-factor" type="u">
<default>2</default>

now run the command

sudo glib-compile-schemas /usr/share/glib-2.0/schemas

Boom, and my greeter got scaled x2 times, just as the desktop already have been.
Thought it will scale my desktop x2 times additionally, but it didn't :D

Does anyone know how to downgrade elementary Hera back to Juno?

The problem with rolling back to Juno (considering you take LinkPhoenix advice to reinstall Juno from scratch) is that Hera comes as an automatic update, so you wouldn't EVER be able to update anything on your system, or Hera would come along. Not sure this is what you want.


How to enable macOS keyboard shortcuts in Juno?

I can address the copy/paste situation, but the Latin issue may require a more in-depth resolution that involves learning xkb and will be outside the scope of my answer as I have not worked that much with providing compose key or multi-language support.

For copy and paste to work with Juno or most any distro you can use xkeysnail or use my kinto app which will use either xkeysnail or xkb to setup keymap switching like you are wanting.

A short example of some remapping I do with it, but you will need the entirety of kinto if you want it to fully configure things for you as it will also setup xkeysnail as a systemd service, something xkeysnail will not do and the complete kinto.py config file will manage several different keymaps for the proper apps by default.

Recommended Backup Tool for Elementary OS

I'm not sure what the elementary developers would recommend, but I can make a personal recommendation for a nice GTK3 back up app called Backups. It's in the AppCenter and can be easily installed and configured. I use it to back up my /home directory to an external drive, that then gets pushed once a week to Google Drive via a cron job.

There are other backup options out there, but personally I've found Backups to work well for my needs.

Best of luck to you!


It will be fixed in future versions, here is a workaround:

cd /usr/lib/x86_64-linux-gnu
sudo ln -s libxmlbird.so.1.3 libxmlbird.so.1.0


You can easily downgrade ( or upgrade ) to any kernel ( even 4.11 ). You could use the CLI to do so. Or you could get Ukuu Kernel Updater.
To install Ukuu type into terminal :
sudo apt-add-repository -y ppa:teejee2008/ppa

sudo apt-get update

sudo apt-get install ukuu

However after downgrading do not remove your stock kernel. If in case anything goes wrong you could revert back to your old kernel.
( And BTW why would you want to "downgrade" the kernel ? ) .


How do I update elementary OS when new versions come out?

For the moment is impossible to upgrade from one version to other, the problem is that they are based in the LTS versions of ubuntu and you can't upgrade from LTS to LTS, I don't know if the elementary team is working in something to solve this problem in the future, but for the moment is not possible to upgrade the system from one release to other directly. One thing you can do is have you "Home" folder in a separated partition, so every time you reinstall the system your files and config are preserved.


How to reset graphic drivers from command line

Thanks to @cl-netbox for instructions/assistance.

You did not provide any details about the hardware (desktop PC or notebook), especially about the GPU.
But you mentioned in your comment below xserver-xorg-video-nouveau, so I assume you have a NVIDIA GPU.
 I will give you a comprehensive answer which should address nearly every possibility to solve your problem.

NVIDIA provides different versions of graphics drivers.

The current stable drivers are distributed through  the official repositories.
The latest official drivers are distributed through the Proprietary GPU Drivers PPA.

Generally you should use the drivers from the official repositories.
When you have issues with these drivers, you can install the drivers from the GPU Drivers PPA.

This often leads to properly working graphics, especially on very new NVIDIA GEFORCE adapters.

Step 1 : Remove NVIDIA drivers you have installed

Open a terminal and execute :

sudo apt-get purge nvidia*
sudo reboot

Step 2 : Identify the exact graphics adapter model

Open a terminal and execute :

lspci -k | grep -EA2 'VGA|3D'

Step 3: (Re)install NVIDIA drivers to the system

For NVIDIA GEFORCE 400 - 700 I recommend to install NVIDIA drivers version 352.

Open a terminal and execute :

sudo apt-get update
sudo apt-get install nvidia-352
sudo reboot

For NVIDIA GEFORCE 800 - 900 I recommend to install NVIDIA drivers version 358.

Open a terminal and execute :

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-358
sudo reboot

In case you experience a black screen, perform everything from a virtual console.
Highlight the elementary OS entry in the GRUB boot menu and press the E key.
Add nouveau.modeset=0 to the end of the linux line and then press F10 to boot.
On the login screen press Ctrl + Alt + F1   and enter user name and password.
Now execute the commands ...


Recentely installed Elementary giving e Not Found W: Failed to fetch ## 404 For every new ppa

How do you add the PPAs?
When I use sudo apt-add-repository ppa:mpstark/elementary-tweaks-daily and do a sudo apt-get update I'm able to install elementary-tweaks without any problems.

So maybe you're right and something is wrong with your installation file.
Did you check the SHA256 sum after downloading the iso?
According to ElementaryOS Installation docs you should do the following to verify the integrity of your file:

In this example the latest 64-bit eOS ISO has been used.

  sha256sum elementaryos-0.3.2-stable-amd64.20151209.iso
  The output should be:
  ee737ffa6bf33b742c5a7cee17aa26dec5ee3b573cbbc4b53cbe2a2513c9197a

If you still have the copy of the ISO you used to install eOS, you can check if the file is corrupt. If so, you have to download the ISO and install eOS again.

EDIT: The links you posted doesn't work for me either. So maybe you just have to correct these in your /etc/apt/sources.list or the corresponding file in /etc/apt/sources.list.d/....
To be sure, I would remove all the PPAs wich gave you a 404 error and add them with sudo add-apt-repository ppa:example-ppa/abc.

How do I disable the middle click in Loki?

Running the following command in the terminal could solve this:

xmodmap -e "pointer = 1 25 3 4 5 6 7 8 9"

To make this persistent, edit your ~/.Xmodmap with a text editor either from the terminal:

nano ~/.Xmodmap

or with a graphical text editor:

  open files --> go to your home directory --> open .Xmodmap (a hidden
  file) with a right click in "Scratch" or another text editor. If the
  file doesn't exist, create a new file with the name .Xmodmap

and add this line

pointer = 1 25 3 4 5 6 7 8 9

Black screen after wake up from suspend mode

I had this problem not only with elementaryOS, but with Lubuntu as well. Its a driver problem.

Do not use the nvidia drivers included in the AppCenter, this is a known bug that happens with the legacy drivers included in most LTS variations of Ubuntu.

To fix just update your drivers using nvidia's driver repo.

sudo apt-get purge nvidia*

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

Check your Graphics cards for a compatible Driver, for example, my GPU is Nvidia GeForce GTX 1050, so it's compatible with the Latest Short Lived branch which is nvidia-396 as the date this answer was originally written.

sudo apt-get install nvidia-XXX

For Elementary OS 5.0 (and other distros based on 18.04 LTS) the package name changed:

sudo apt-get install nvidia-driver-XXX

Replace XXX with the version your GPU is compatible with. The latest, the better.

Restart, the problem should be fixed.

Proper way is to type in terminal :

Primero quizás deberías actualizar a Loki, Trusty tiene soporte pero no sé si el resto de componentes de Freya lo tenga aún.

Aparte de eso, puedes ejecutar Geary desde una terminal y revisar si aparece algún mensaje de error. También puedes probar abrirlo desde la sesión de invitados: si tampoco inicia, prueba reinstalándolo desde una terminal con sudo apt-get install --reinstall geary; si arranca normal, prueba eliminar las carpetas donde guarda la configuración (~/.config/geary y ~/.local/share/geary).


Can Apache 2.4, PHP be installed and used with elementary OS?

They should run fine! These applications all work on Ubuntu. In general, software that works on Ubuntu also work on elementary.

I'm running Apache and PHP in a virtual server using Vagrant, and that setup works well for me. You should be able to run these applications directly on elementary, if you'd prefer.

The dconf-key is located under /io/elementary/terminal/settings/natural-copy-paste. If you change that value to false, Ctrl+C and Ctrl+V shouldn't be copying/pasting text anymore.


To disable ad-blocking in eOS, you need to open the browser, click on the gear icon, and set the preferences to allow ads.
However, this isn't the kind of fidelity that you're looking for. In Epiphany, the eOS default browser, ad-blocking is binary, meaning that it is either on or it is off. You can't disable it for individual sites while keeping it enabled for other sites.
Your most realistic solution is to install another mainstream browser, such as Firefox or Chrome. Then, install an ad-blocking extension - such as uBlock Origin. With that extension, you can visit the site, click on the extension in the browser's notification area, and disable ad-blocking for individual sites.
There are other browsers (such as Vivaldi, Brave, or Opera) that have built-in ad-blocking. In each of those cases, you also have the fidelity to disable blocking on a per-site basis.


bumblebee vs nvidia-prime? What to use that works with latest nvidia driver?

In my experience bumblebee is a fine balance between performance and battery life. It has been reported, however, that installing nvidia-prime will cause better performance on gaming, for example.

Nvidia-prime cannot be activated in a per-app basis, so if that is what you need from it you should go with bemblebee.

You can arguably install the latest drivers with bumblebee provided you install specific ppa for that.


Plank has zoomed to fit screen width after recent update

I'm not sure what caused this on your system, but it looks like you've set the icon size to something enormous, try scaling down the icons by putting your mouse over the plank and using [ctrl] + [scrollwheel].

if that doesn't work try entering plank --preferences into slingshot or a terminal and tweaking the settings yourself: the two you'll be interested in are icon size which has a default of 48px and alignment which should be on center not fill.


Can't get elementary to install on a USB stick

When you click to format it to ext2 also check the box: "format this partition" if not already and in the drop-down box below select the option which just says / (you should see something like /,/home,/root,/boot etc)


Problem with elementary os juno after wake up

srda1989,

Welcome to the Elementary OS forum.

The first thing I would look at would be to determine what processes may (or may not) be hammering your powerful system.  One way to do this is through the terminal.

Go to Applications -> Terminal (or Win+T)
At the terminal prompt type the following command:

top

This will show you (in real time) which processes are hammering away at your system.  The important things to look for are (1) anything that shows a high percentage in the %CPU column and (2) the %Cpu(s): line.  Especially the xx.x id number.  Theoretically, that number should be close to 100 as possible.

If, on the other hand, some process is grabbing a high percentage of the CPU then it gives us some place to focus on solving your unresponsive issue.

Finally, the top command will continue to run until you type the following letter:

q

Good luck!

In case u dont have gksu, type

sudo apt install gksu

DON'T forget to REBOOT !


Pantheon Mail still showing notifications after uninstall

I used sudo apt purge to remove mine and have no problems, but I never signed in to an account. If it was not a clean uninstall perhaps reinstalling and ensuring your accounts are disconnected before removing the program may help.

Flicker using browser and strange behavior with the mouse

SOLUTION: I was able to find a fix for this. It was weeks ago so I had to research again to find the command. Basically it seems to be related to the Intel graphics drivers on the Dell machines. I believe the command I ran was

sudo apt-get purge intel-linux-graphics-installer

Let me know if that works for you.

I have the same issue (Epiphany - Weird glitching and corrupt fullscreen video)

I have notified Daniel and Cassidy but I don't think they have been able to reproduce it. I am also on a Dell, i7579 with a Kaby Lake i5. Though I am only having problems in ephiphany and it's only after I update. On a fresh install it does not happen. It seems to be related to the mouse from what I can tell.

I posted a video, let me know if this is the same issue you are having...

"Cable unplugged" For wireless connection

Apparently sometimes the wifi is getting softblocked by network manager. The solution was unblocking it using nmcli r wifi on. I don't really know how this happened, but it's certainly a bug. I will probably report it to the network switchboard plugin github issues later.


Don't worry about installing the AMD graphics drivers. The open source drivers that come with Elementary OS are the best AMD graphics drivers. What you are trying to install is too old and no longer supported.

You may also update your kernel and see how that works for you.

Alright, buckle up your big boy pants because you are going balls deep today!

We get to play with the terminal. This guide is made assuming that you can get to the terminal [(edit) and the Desktop GUI.] Here is a list of commands that will set you up and upgrade your kernel.

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install software-properties-common

sudo apt-get update

sudo add-apt-repository ppa:teejee2008/ppa

sudo apt-get update

sudo apt-get install ukuu

sudo apt-get upgrade

Now go ahead and use UKUU to update the kernel to 4.11.3
It will say that there are errors the first time you try this, ignore
that.
Reboot your computer.
Go back to UKUU and reinstall 4.11.3 kernel
If the install was successful, go ahead and restart your computer
again.

Now run

sudo apt-get purge ukuu

sudo apt-get update

sudo apt-get upgrade

If you only have access to the terminal use this advice given from Lemonslice

As a workaround, you might want to try to install 4.11 from the Ubuntu mainline kernels.
You can download and install from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.11.4/ the following packages:

sudo dpkg --install linux-headers-4.11.4-041104_4.11.4-041104.201706071003_all.deb \
linux-headers-4.11.4-041104-generic_4.11.4-041104.201706071003_amd64.deb \
linux-image-4.11.4-041104-generic_4.11.4-041104.201706071003_amd64.deb

Now restart your computer when your kernel is installed and continue on.

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

sudo apt-get update

sudo apt-get -f install

sudo apt-get install gcc-6 g++-6

sudo apt-get update

sudo apt-get upgrade

Now reboot your computer again for good measure.

When you computer has restarted go ahead and run

sudo apt-get autoremove

Say yes to any prompts.
Reboot your computer and now try your multimedia keys and possibly
your video drivers.

I have to do this for my laptop and desktop for it to fully function. The 4.11.3 kernel is really good and has not given me issues.

So yeah, it seems like a lot, you can do it. Have confidence!


Have application menu open up with only Windows/Super key

You can assign Super key to open Slingshot-launcher on Loki with following commands:

How to limit the number of wireless networks listed in the wingpanel

There is no such functionality. But there is a bug over there at Github which is similar. Please elaborate there your wishes as in the last comments here. Some of your ideas seems worth to discuss there.


just did a DDG search on "ACPI PCC PROBE FAILED"
and found this page
http://yeites.blogspot.com/2015/05/acpi-pcc-probe-failed-starting-version_29.html

From this ... it appears that there could be an SCPI issue ... I dont remember how to do this on a macbook ... but try turning it off and then see if it works

caveat -- apparently you cannot put to sleep after doing this


How to add folder sharing or sharing options to the File manager context menu?

Sharing Options in Files
I don't believe this is possible directly from Files.
Alternatives
The configuration files for your samba server can be modified with a text editor or graphically with the system-config-samba utility or GNOME Files, packaged as nautilus, with the nautilus-share plugin as you mentioned.
The Ubuntu Wiki's Samba Server Guide serves as a good reference for the various methods of configuring a samba server.
It sounds like you're used to using GNOME Files, so I've included the command to install it with the share plugin here.
sudo apt -y install nautilus nautilus-share

Files Plugins
Plugins for Files can be found with the following command via apt, but this only shows a Dropbox plugin at the moment.
sudo apt search pantheon-files-plugin-

Files Website
The File's GitHub repository can be found here.


Press Ctrl+Alt+F1 and login into the shell.

Now run ls -lA | grep 'Xauth*'. you'll see the line

-rw-------  1 root root   53 Nov 29 10:19 .Xauthority

then you need to do chown username:username .Xauthority and try logging in (you may also need to do the same for for .ICEauthority).

Else, do ls -ld /tmp. Check for the first 10 letters in the left: they should read exactly so: drwxrwxrwt.

drwxrwxrwt 15 root root 4096 Nov 30 04:17 /tmp

Else, you need to do sudo chmod a+wt /tmp and check again.

Now press Ctrl+Alt+F7 to reach the login screen again, and restart.


Why is LibSoup not found when compiling Vala?

I am being told by people more knowledgable than myself for Vala that your compile command is not quite right. Every package needs the --pkg prefix, and you need to specify the full packages name as you have done with gtk+.

Something like valac soup.vala --pkg libsoup-2.4 --pkg gtk+-3.0 should work out a whole lot better for you.


Elementary uses LightDM for login. Please refer to the LightDM arch wiki for info on the GTK+ Greeter and how to change the wallpaper.

https://wiki.archlinux.org/index.php/LightDM

But basically you can run the following:

sudo apt install lightdm-gtk-greeter-settings

Then run the app and make your changes there.


How to remove the window header or decorations?

This is not really possible without forking the application. Decorations are drawn by the toolkit now instead of by the window manager which means that they are actually part of the application and not something separate.


libnss3 package version update (document signing issue)

You can download the .deb package from libnss3_3.45-1ubuntu2_amd64.deb
. After that, you can use Eddy to install it.

Before installing the package:
libnss3 is already the newest version (2:3.35-2ubuntu2.7).

After installing it:

vlad@lenovo-y530:~$ apt list libnss3 -a
Listing... Done
libnss3/now 2:3.45-1ubuntu2 amd64 [installed,local]
libnss3/bionic-updates,bionic-security 2:3.35-2ubuntu2.7 amd64
libnss3/bionic 2:3.35-2ubuntu2 amd64

Please let us know if this solves the signing issue.


Wingpanel adds shadow and defaults to white font after restart on light background

For now until that bug is fixed, you can force the light background state in your ~/.config/gtk-3.0/gtk.css - if the file and subfolder does not exist, just create them.

.composited-indicator > revealer label,
.composited-indicator > revealer image,
.composited-indicator > revealer spinner,
.panel.color-light .composited-indicator > revealer label,
.panel.color-light .composited-indicator > revealer image,
.panel.color-light .composited-indicator > revealer spinner {
    color: alpha (#000, 0.65);
    text-shadow:
        0 0 2px alpha (#fff, 0.3),
        0 1px 0 alpha (#fff, 0.25);
    -gtk-icon-shadow:
        0 0 2px alpha (#fff, 0.3),
        0 1px 0 alpha (#fff, 0.25);
}

If you'd want to have light on dark background instead, modify it to be:

.composited-indicator > revealer label,
.composited-indicator > revealer image,
.composited-indicator > revealer spinner,
.panel.color-light .composited-indicator > revealer label,
.panel.color-light .composited-indicator > revealer image,
.panel.color-light .composited-indicator > revealer spinner {
    color: #fff;
    font-weight: bold;
    text-shadow:
        0 0 2px alpha (#000, 0.3),
        0 1px 2px alpha (#000, 0.6);
    transition: all 200ms ease-in-out;
    -gtk-icon-shadow:
        0 0 2px alpha (#000, 0.3),
        0 1px 2px alpha (#000, 0.6);
}

The hint at the solution was found on reddit, for history sake a quote:

  Take a look at this css in wingpanel's source. If you were to copy and
  paste that into your ~/.config/gtk-3.0/gtk.css, you should be able to
  override the color of the icons. I've highlighted the part for when
  the panel is on a light background. If you set the properties to the
  same values in both sections, the icons should always be those colors
  (you could copy the values from the first section to the second to
  always have white icons, or copy the values from the second section to
  the first to always have black icons). To demonstrate, I made
  wingpanel have red text and icons.

The source mentioned is here: https://github.com/elementary/wingpanel/blob/master/data/styles/application.css

Is it possible to improve Battery life & Overheat?

You can install TLP to improve it. You will find an answer in Google how to install it in Ubuntu. Because Elementary OS is based on Ubuntu repo, you can install the software identical way in Elementary OS like in Ubuntu.

how to get the grub menu to show when starting computer

In Terminal put in: sudo gedit /etc/default/grub
Do this: GRUB_HIDDEN_TIMEOUT=0 -> #GRUB_HIDDEN_TIMEOUT=0
This allows the the grub menu to be displayed and not hidden.
Save the file
In terminal put in: sudo update-grub

This might not work but is one of the most common reasons for grub to be hiding.

sudo add-apt-repository ppa:elementary-os/os-patches
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install elementary-desktop

Dual boot with Windows 10 on external drive not working

I do not know if it will work, but you can try to type into the elementaryOS terminal sudo update-grub and check out do you have a message similar to Found Windows Boot Manager on /dev/...
This is the official way to add boot entries so if it founds it probably will add it like an option. I type 'probably' because I have no experience with dual external ssd boot. Hope that helps


Maya Calendar right window remains empty

No that is most definitely a bug, you could try running the latest master as there have been quite a lot of fixes recently about events not showing correctly in Calendar, however that would require building it, if not wait for the next release of Calendar. Sorry for the bad news.


Found the issue: There was a BIOS option marked "Secure Boot" or something like that. I'm unsure what it does but I decided to disable it and BINGO.


sudo apt install name-of-package is the right way to do it.

One way to go about this is to double-check that you are giving the right package name.

You can look for the desired package/app with: apt search name-of-package

If that doesn't work for you then reply with the error that you are getting in terminal.

Cheers


Probably be the mirror from your packages, I usually setup to the us servers.

Just go to /etc/apt

Once you are here just open the file source.list, No the one that it's source.list.d

Or you can do it via terminal, using any text editor:

Nano

  sudo nano /etc/apt/source.list

Atom

  sudo atom /etc/apt/source.list

Now you will see all the apt link that Elementary use download the updates

For example:

  deb http://ph.archive.ubuntu.com/ubuntu/ bionic main restricted

Now just change the region from ph to any other, in this case us

  deb http://us.archive.ubuntu.com/ubuntu/ bionic main restricted

Hopefully this works, maybe it's a little bit slower but you can try another servers.

Check the mirror list HERE

Locked out of computer since install crashed

Learn about boot repair and super grub2 disk, and eventually rescatux. For an old mac I recommand to install rEFIt from mac os X if you still have it.

Can you boot from live usb? If yes I think the best choice for you wood be to format your disk ( Create new GPT partition table, and loose all the data on the computer!) and then clean install elementary os 0.3.2 . If you have 0.3 or 0.3.1 downloaded it is important to download again.

An other thing thing that you can try is pressing alt or C during boot process, you will need a wired keyboard (I think).

I am currently using an old macbook.


Is brightness control supposed to work on desktop systems / external displays?

This is not specific to a elementary. External monitors configurations are managed by themselves. You can control your laptops brightness because the monitor is directly managed by your laptops drivers. This applies to Windows and macOS as well.
There are many tools to workaround this but no OS provides this as native functionality.


Emmanuele's position seems to be that there are better alternatives to Vala, so you should use them instead; based on his tweet about LLVM-based languages, I'm guessing he is a fan of Rust.  I've played with Rust a bit, and while I prefer it to JS and Python, I like Vala much better…  For me, Rust isn't a better alternative, it's an worse alternative (though still better than JS or Python).

Every language has its warts.  Emmanuele mentions some of Vala's big ones, but if those warts don't bother you why should you care?  If you're happy with the current gdb support, what does it matter that it's not better?  I may not be a typical user, but I actually prefer debugging the generated C since it gives me a better view of what is really going on.  Vala isn't be seeing a lot of new feature development (especially compared to languages like Rust and JS), but it's still alive.  Personally, I don't feel a great need for most of the features it's lacking, and I find it it much more pleasant than the other options for writing GNOME/GTK+ applications, so I'll continue to develop new applications in Vala where appropriate.

If something major which is lacking from Vala right now is a deal-breaker for you, you probably shouldn't get your hopes up that someone else will add that feature for you down the line, and should instead move on.  Your other choices right now are basically JavaScript, Python, and C (Rust is coming up quickly, I think it will be a viable choice very soon).

Also, ebassi != GNOME.  I have a lot of respect for him (and, therefore, his opinion), but the story isn't "GNOME discourages using Vala for new projects", it's "a prominent GNOME developer discourages using Vala for new projects".  GNOME recommends JavaScript for new projects, and has for a while (a couple years, IIRC) now.  That said, new applications are still being written in Vala, Python, C, and whatever people want to write them in.


Booting elementary OS from USB stick on old Dell Inspiron 8200 with Knoppix in German

The 8200 does not have usb 2.0, and does not support booting from usb

http://en.community.dell.com/support-forums/desktop/f/3514/p/19337400/19715801.aspx#19715801

Your best option will be to burn Freya to a cd rom.

Source: https://superuser.com/questions/629785/old-dell-dimension-8200-running-windows-xp

Then:
you can change the boot sequence in the bios, but the f12 boot menu is much easier. Press f12 on the dell logo, it should give the option to boot normally, from floppy, or from CD/DVD. Just put in the Freya DVD, choose to boot from DVD, and then watch the screen for the "press any key to boot from CD/DVD" message, as soon as you see it, press any key on the keyboard and it should boot to the DVD for you.

Finally try a live session to check everything works fine and proceed to install as the only system in your computer. You can let the system choose the partitions by default which is fine.

Are there any alternatives to the default terminal, pantheon terminal?

Gnome Terminal:
The Gnome terminal supports multiple profiles, you can install from the Software Center or with this command
sudo apt-get install gnome-terminal


If it's an EFI install you can simply use a program like GParted or Gnome Disk Utility to delete the Windows partitions (not including the EFI partition) and then run 'sudo update-grub'. If you run 'sudo ls /boot/efi/EFI/ubuntu' what do you see?


This is what works for me (keeping secure boot enabled), but you will need to do it every time the kernel is updated:

1. Create signing keys

openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -days 36500 -subj "/CN=Descriptive name/"

2.Sign the module (vboxdrv for this example)

sudo /usr/src/linux-headers-$(uname -r)/scripts/sign-file sha256 ./MOK.priv ./MOK.der $(modinfo -n vboxdrv)

3. Register the keys to Secure Boot

sudo mokutil --import MOK.der

Supply a password for later use after reboot

4. Reboot

Reboot

and follow instructions to Enroll MOK (Machine Owner Key). Here's a sample with pictures. The system will reboot one more time. After the reboot, you may also need to

sudo modprobe vboxdrv

to load the module.

Is there a way to theme Atom to fit in with elementary?

Yes there is. There's a special UI theme called elementary-light-ui that you can use. The theme was created by one of the main elementary's developers (Cassidy James). To install it, just type in the following command:

apm install elementary-light-ui

After it, just press Ctrl+Shift+P, type change themes, press Enter and select elementary-light-ui as your new UI theme.


Just check a few things.

Enter BIOS and disable Secure boot
Enable USB boot
Set Boot Priority to USB by default

Installation:

Boot your USB and complete basic setup until you reach partition manager. Select the last option "Something else" to proceed with partition manager.
In partition manager,

Select free space, and create a primary 20000MB partition as root denoted by / marked at beginning of space.
Select free space, and create a logical 4000MB partition as swap area from dropdown marked at beginning of space.
Select free space, and create remaining space as a logical partition for home denoted by /home marked at beginning of space.

IMPORTANT..! Select the Windows Boot manager partition (EFI) from the drop down at the end of partition of table. And then click INSTALL.
Click Next and complete the setup. You will recieve a dialog box as REBOOT once installation completes. Just reboot and unplug your USB media.

Enjoy Elementary Loki..!

IF IT STILL ENTERS INTO WINDOWS

Enter into BIOS and change the order of OS Boot manager to Ubuntu/Elementary as default. It should now load the Linux grub loader.


You can install it  from terminal sudo apt install keepassx. I did it that way as I was unable to find it in App Center.


Will Logitech K380 and MX Master work on elementary OS?

Since Ubuntu is the base for Elementary OS anything that works in Ubuntu should work in it's derivatives.  If the mouse and keyboard worked in Ubuntu 16.04 it should work in Elementary Loki


Yes,it's completely normal.

The propietary NVIDIA drivers go trough a process that starts from the NVIDIA devs and ends on the Ubuntu/elementaryOS repos. The version available on the NVIDIA website is not a stable version so you would need to wait a bit more to use that one.

Usually it's safe to install any version from the Ubuntu repositories. Those have already been tested so they should work. You are using the 367 version because that's been tested already but there's a newer one (375) that hasn't been tested so installing it may break your system.


Right-click > New menu is overflowing with unnecessary options

The "New" list in the right-click menu draws from XDG_TEMPLATES_DIR in .config/user-dirs.dirs.
Running the command tail ~/.config/user-dirs.dirs showed that XDG_TEMPLATES_DIR was set as $HOME and hence was trying to use all the various dotfiles in the home directory as templates.

Amending the file so it says XDG_TEMPLATES_DIR="$HOME/Templates" followed by a restart fixed the issue.


What are the rules about developing closed source software for elementary OS?

Please keep in mind I'm no expert: I gathered some information about closed source software, but I cannot guarantee completeness or even truth.

GLib, GTK+, Granite and Vala are licensed under the LPGL. Here is the TL;DR for this license. When your application is dynamically linked to these libraries (which is default when you build an application for elementary OS / Linux in general), you do not have to disclose your source code:

  Derivative works (including modifications or anything statically linked to the library) can only be redistributed under LGPL, but applications that use the library don't have to be.

While the basic libraries I mentioned (which are necessary for creating an elementary OS app) are licensed under LPGL, others might not. So if you are looking for advanced functionality in additional libraries, you should be really careful about the GPL license. The GPL itself requires you to open your source code for every owner of your application and it "infects" software which is using it. So you'd have to release your app under the GPL as well.
Some GPL-licensed projects do provide a GPL linking exception. So, if in doubt, message the developers and ask about their stance.

One thing you should keep in mind though: Linux users are used to open source software. While the closed source state of some software is accepted / tolerated for various reasons (for example nVidia/AMD drivers or Google Chrome), people might reject the idea of a "simple" application being closed source.


Well, first of all, that's not a Geary indicator, that's indicator-messages and it has a lot more functionality than just displaying Geary notifications.

To delete it completely from your system, you can execute this command:

sudo apt-get remove indicator-messages

After it, all you need to do is to re-login (I have just tested this and it works).

Names of other default indicators:

indicator-power (the battery icon)
indicator-bluetooth (the Bluetooth icon)
indicator-datetime (date and time indicator in the center of Wingpanel)
indicator-sound (self-explanatory)
network-manager-gnome (network icon)

Alternatively, if you just want to disable their startup but not remove them from the system, you could try to go to /etc/xdg/autostart and delete their .desktop files (note: I haven't tested this method).


Install

sudo apt install exfat-fuse
sudo apt install exfat-utils

I am just making an answer so that it is solved and people know this.  I always have this problem with every distribution.. except I think Mate may have included it.


Can elementary OS be installed on a laptop that you can't disable Secure Boot?

I was able to install elementary OS with secure boot. During installation, I was partitioning the drive; it recognized that I was in secure boot mode and noticed that I did not have an EFI partition. I repartitioned it with an EFI parition (mounted at /boot/efi) and then elementary OS installed just fine.


Displaylink driver - Turning folder back into .run

I was having trouble with this too so I modified AdnanHodzic's code to run on elementary. You can find the source here https://github.com/jpopesculian/displaylink-debian

Do a git clone: git clone https://github.com/jpopesculian/displaylink-debian.git
And run the file: displaylink-debian/displaylink-debian.sh

Let me know if that works for you!


To speed things up, you may want to report this issue directly to Lyrics or Give Me Lyrics developers.


Elementary OS is unstable when using with a 6th Gen CPU

Running the command sudo apt-get install linux-generic-lts-wily will upgrade your Kernel to 4.2, which solved many of my issues with Skylake.


How to change the window manager's mouse click actions?

You can use gsettings:

gsettings set org.gnome.desktop.wm.preferences action-middle-click-titlebar 'none'

Will disable the feature. To re-enable, use this:

gsettings set org.gnome.desktop.wm.preferences action-middle-click-titlebar 'lower'

These are the options you can set it to:

toggle-shade, which will shade/unshade the window (roll up / down)
toggle-maximize which will maximise/unmaximise the window
toggle-maximize-horizontally and toggle-maximize-vertically which will maximise/unmaximise the window in that direction only
minimize which will minimise the window
shade which will roll the window up
menu which will display the window menu (default for right click)
lower which will put the window behind all the others
none which will not do anything, and effectively disables this action.


Album art can't be seen in Music Application?

Check the folder containing your albums to see if they include an album cover image.


Tried installing EOS tweaks, failed and now apt update doesn't work

Try this:

1) first remove previously added repository:

sudo add-apt-repository --remove ppa:philip.scott/elementary-tweaks/ppa

2) Then add it manually:

right-click Files icon, select New Window as Admin and go to /etc/apt/sources.list.d/;
in that directory, create an empty file and name it philip_scott-ubuntu-elementary-tweaks-bionic.list;
open that file (i.e. in Code or any other text editor) and paste the following two lines into it:

deb http://ppa.launchpad.net/philip.scott/elementary-tweaks/ubuntu bionic main

# deb-src http://ppa.launchpad.net/philip.scott/elementary-tweaks/ubuntu bionic main
save and close the file and try to sudo apt update.


We narrowed the issue down to a single indicator, so the temporary fix is to remove it for now:
sudo apt-get remove wingpanel-indicator-power
I'll report back once the bug is resolved, but I otherwise recommend following the report in case more feedback is needed.


Cut, Copy & Paste shortcuts were not working

Hi i had same problems too after a little search i solved. To solve the problem you have to move English up from the options-->keyboard


Should I download the Loki Beta or Freya Stable?

I'd recommend using Freya for now. The beta version of Loki is buggy and not ready for everyday use. From the release announcement:

  The purpose of releasing a beta is to give developers time to update their apps prior to stable release [...] Beta represents a more-or-less feature-complete release, but it does not represent a stable release.

As far as I know, there wasn't an official upgrade path from Freya beta to Freya stable, and I'd expect the same with Loki. No matter whether you choose Freya or Loki beta, you'll still have to do a clean install to upgrade.

To make upgrading simpler, you could move your home directory to a separate partition. Alternately, you could keep your files in Dropbox or Google Drive.

There are instructions on upgrading from Freya beta to Freya stable, and you might be able to adapt these for Loki. (For example, you'd probably need to change utopic to xenial). That said, I personally wouldn't recommend this approach. It's untested and might result in an unstable system.


You may try compiling this drivers from https://github.com/lwfinger/rtlwifi_new like this:

You should try a possible solution I wrote in detail based on https://askubuntu.com/a/990571/890782

Check it out here:

https://elementaryos.stackexchange.com/a/17764/14940


Depending on how you've originally installed eOS there's a good chance you can boot into a 'recovery mode' (via the Grub menu) which is normally accessed by holding down the esc key immediately after turning your system on, or a restart process begins, and then only after any BIOS entry shortcut has timed out. If your system boots into the Grub menu you'll know it - minimal text based menu navigated by arrow keys with menu items labeled with the operating system the selection will boot into.

Recovery mode (if it was installed) would then be under the main menu item labeled 'Advanced elementary os options'. Select that and it should give you a list of secondary boot options - one of which should have 'recovery' in its label.

After selecting a recovery boot option - another minimal looking menu eventually comes up. That one will have options centered around recovery specifics all of which are relatively safe to pick from. Can't say those would fix your login issue - but they're worth a try.


That's a known bug that may be out of the scope of elementary. Anyway the fix is to run the app with GTK_CSD=0. You can do this from the command line:

GTK_CSD=0 playonlinux

And you can also modify the .desktop file so that it works automatically when you open the app. You just need to find the line starting with Exec= and add env GTK_CSD=0 to it so it looks like

Exec=env GTK_CSD=0 /path/to/playonlinux


Wireless Connection disabled in elementary OS on Lenovo t430s. Help?

I had exactly the same problem on a T430 a year ago. I was going nuts until one of my colleagues calmly pointed out the little switch on the right hand side of the base. I slid this across and wifi sprang to life - essentially it wasn't clear which was was on and which was off. I cursed that I hadn't known about that a couple of hours earlier... There is a BIOS switch as well but that had been allowing wifi all the time.

Check https://support.lenovo.com/gb/en/solutions/pd025182 for more details.


Support for Genie is built into the Vala compiler.  You can install the Vala compiler as follows:

$ sudo apt install valac

From this you may compile either Vala or Genie, as, for example:

$ valac example.gs -o example

Then run as:

$ ./example

You can also compile both Vala and Genie as, for example:

$ valac example.vala example.gs -o example

If you are feeling more intrepid, Gnome-Builder is an IDE that can be used to build projects for both Vala and Genie using the Meson build system.

Stackoverflow has a tag for Genie; it can be found here.

The best documentation on the internet may be found at the Elementary OS Developer Center.


Mouse cursor invisible after installing Parallel Tools

So here is the solution if you are using Parallels to install ElementaryOS Loki

There is no Parallel Tools driver issue. It is just Boot Flag setting.

After installation of Parallel Tools, shut down and don't start Loki. Go to

Settings --> Hardware --> Boot Order

There you would see Advanced Settings, where you can set the boot flags. Type there

devices.usb.mouse=1

And now start your Virtual Machine, it would work

if 1 doesn't work then try 0. But for me in Parallels, 1 worked


Where are the screenshots saved to in 0.4?

There is a bug in Loki, which is not allowing to take the screenshot. The Question has been asked here earlier. And the Bug too has been confirmed.


Can I install another desktop environment in elementary OS?

It's probably possible to remove Pantheon/Granite and install GNOME on elementary OS, but it's also a bad idea. :) Installing GNOME would likely result in an unstable OS. In addition, apps that are designed for Pantheon/Granite may break in GNOME.

I'd recommend installing a version of Ubuntu that is configured to work with your desktop environment of choice. For LXDE, there's Lubuntu. For GNOME, there's Ubuntu GNOME. You can install another flavor of Ubuntu alongside elementary, run it on a virtual machine, or boot it from a live CD if you just want to do a test drive.

For way more details, see this question about installing KDE.


GtkStatusIcon is deprecated since GTK 3.14. It is more for Windows and KDE and not supported on elementary OS or Gnome 3.


Bluetooth and laptop speakers working at the same time

you can try to install PulseAudio volume control from the app center and then change the profile in configuration and the output device


I just installed Loki and "The Panel" has disappeared.

Open a terminal type wingpanel. This will start wingpanel process and wingpanel will appear.


Can not update applications because off unauthenticated sources

Yes, I've had this problem in the past. Researching about authentication GPG keys, I found out that there is a limit to how many GPG keys it stores. As a result, some keys are not verified. On the other hand, if you're feeling adventurous at downloading apps in repositories that are not signed, this can also give you the error. Other users suggested Y-PPA Manager. This didn't do the trick. What did do the trick for me, not sure it will work for you, is installing Gconf Cleaner. It cleans GPG keys that are no longer available because if uninstalled apps, reinstalling apps or the repositories no longer give support to those GPG keys. Warning: messing around with the source list on your own can make your situation worst!


Terminal panel color different than other

This is normal, probably it's chosen where it was deemed appropriate. For example a darker border around a Video is less "distracting". Daniel Foré is working on a light theme for Terminal: https://www.youtube.com/watch?v=wOAlqsA0XF0

Not sure why such choices aren't covered in the Human Interface Guidelines
https://elementary.io/docs/human-interface-guidelines


This is a known issue which effects several applications. To fix it edit the ~/.config/autostart/dropbox.desktop file and change the Exec line to this:

Exec=env XDG_CURRENT_DESKTOP=Unity QT_STYLE_OVERRIDE="" dropbox start -i

Log out and back in and the icon should be correct. I have noticed that even with this the menu sometimes does not appear correctly, but usually a second click will work.

My complete .desktop file:

[Desktop Entry]
Name=Dropbox
GenericName=File Synchronizer
Comment=Sync your files across computers and to the web
Exec=env XDG_CURRENT_DESKTOP=Unity QT_STYLE_OVERRIDE="" dropbox start -i
Terminal=false
Type=Application
Icon=dropbox
Categories=Network;FileTransfer;
StartupNotify=false
X-GNOME-Autostart-enabled=true


You can install MegaSync from here (use Eddy if you want to do it from a GUI), and install Ayatana indicators, which will show the 'normal' tray icons. But keep in mind that this is an unsupported change. If you really want to do it, just install this and this and you're good to go.


How to create a desktop or plank shortcut for Musique (Flavio Tordini app)?

Open AppEditor and make a new entry.

It is always recommended to leave the 2 latest versions of the kernel, but to remove other kernel versions I used the following commands:

dpkg -l | fgrep linux-image-

Never remove the kernel shown in uname -r or linux-image-generic-lts-utopic.

Finally sudo apt-get purge <package names> for the kernels you want to remove (see screenshot for reference).

Then sudo update-grub to update the Bootloader.


Determine if Notebook or Desktop in Vala

What makes you think it's not possible to adjust brightness on a desktop?  It may not be possible on your desktop, but that doesn't mean it isn't possible on someone else's…

You're also going to run into the problem of how you define a laptop vs. desktop (and, to take it further, a tablet).  It's common to find laptop parts in desktop computers, especially all-in-one machines, NUCs, etc.  The best thing I can think of is checking to see if /sys/class/power_supply/BAT* exists, but I think connecting a UPS to a desktop computer would populate that…

If I were you I would try to take a look at the API you're using to set the display brightness to see if it provides a way to check whether the display actually supports it.  If so, it would probably be best to use that instead.


Remove these directories

rm .Xauthority .ICEauthority

And clear cache

rm -Rf .cache

These commands helped me solve your problem


for me

sudo apt install remmina-plugin-rdp

worked fine!


How do I make the terminal font a little brighter?

If you want to change the font color, you can use Configurator. Once you've installed the application, you go to org.pantheon.terminal.settings and change the value of foreground to any color you want. The default color in my system is #94a3a5

If you don't want to use Configurator(or dconf-editor) you an use terminal and paste this
gsettings set org.pantheon.terminal.settings foreground '#000' and change #000 with the color you want.

To restore the default color settings , paste this on your terminal
gsettings set org.pantheon.terminal.settings foreground '#94a3a5'


Why can I not use Scratch text editor to create files from the Terminal?

You can set up an alias to create the file if it doesn't exist. First, create the bash file:

touch .bash_aliases
scratch-text-editor .bash_aliases

Then add the following:

scratch() {
    touch $1
    scratch-text-editor $1
}

This will set the command scratch to make the file (with touch) and then edit it with scratch-text-editor. $1 means the first argument given.

This solves the other issue of the command for scratch being annoyingly long. Anyway, restart your terminal, and check the top. If you see an error like this:

bash: /home/tim/.bash_aliases: line 2: unexpected EOF...

or any error about the file, then check you've entered it all correctly.

Google chrome does not appear in installed list in app center

Google Chrome has to be downloaded and installed either with dpkg or a graphical front end, such as Eddy

After installing, you can safely delete the .Deb package, as the application will appear under the 'updates' tab in your AppCenter, and can be removed from there.

Such an operation is called sideloading, and while generally discouraged, it is also at time necessary.

UPDATE:
On my computers, chrome doesn't show up in the AppCenter either, after installing it through the above stated methods. They do however, both, run the current version of it, so yes, it does get updates


Maybe this is useful for you:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1784152

First open Terminal and visit your Downloads folder by typing:
cd Downloads

Next you need to depackage(extract) the installed deb files using dpkg as below:

sudo dpkg -i <your-.deb-package-name.deb>

Example: For your installation type sudo dpkg -i google-chrome-stable_current_amd64.deb

Repeat for all .deb files.

ALTERNATIVELY:

Right click the .deb file and select Open with > Software Center


Open AppCentre and go to the updates tab. Wait some seconds til it loads everything and go to the Drivers section.
There install the latest nvidia driver (the one that has a higher number, in my case is 384, it may be different in yours).

When it finishes installing everything, reboot your system. Now go to Applications and search for "NVIDIA X Server Settings" and open it. You can now choose what GPU you want to use. Beware you'll have to logout and login again every time you want to switch GPUs.


Wifi not available on Juno using rtl8812au driver and usb wifi stick

Compiled from comments: The instructions on How to install Realtek rtl8812au WiFi Driver in Linux seem to work for this wifi device. The article refers to a GitHub repo containing a version of the rtl8812au linux driver, updated to compile against newer kernels. Since there is a huge list of USB WiFi adapters built using this chip, we can expect a flow of requests regarding installing it.

Here's a summary:

git clone https://github.com/AstroDrabb/rtl8812au
cd rtl8812au
sudo ./install.sh
**follow the script's instructions**

The above repository also contains instructions on adding the driver to dkms, so that it survives kernel update.


How uninstall apps and choose the firewall?

Everything you do via App center you can do via command line

Linux Rules!!

sudo apt remove epiphany-browser

** if you would like to remove its dependencies the replace remove with autoremove, but it might remove needed depencies as well, so proceed with caution

but I think I've also found it in the app center, it's called "gnome web"

I have had troubles with the videos app as well. You could open it by starting it from the terminal with:

audience

Then copy and paste the output of the command here to give us more info.

You could try installing libdvd-pkg which should install everything you need to play a dvd.

sudo apt-get install libdvd-pkg

You will then need to run the following afterward

sudo dpkg-reconfigure libdvd-pkg

to finish the installation.

Reference:
DVD Issues in 16.04

The link also has additional suggestions you might want to try.

Here are a few things I have noticed:

light-locker needs to be running - I had disabled it and this causes
videos to crash
I need to open files and mount the DVD by clicking on it before I can
open it in videos
Sometimes videos tries to open my LRS_ESP partition (I have a multi-boot system) and play it instead of the DVD drive.  Not sure why.  Usually corrects if I unmount that partition then try again.


Everything works again! No need to reinstall!

I pressed Ctrl+Alt+F1 to boot into tty1 and the $DISPLAY environment variable was empty.

So redefined the DISPLAY variable using export DISPLAY=:0.0 and rebooted. That's it.

P.S. IIRC, I may have uninstalled UXTerm before the running the update.

Incredibly slow Terminal when modifying characters

After looking at the bug tracker linked by @elmato, I found an issue about vim being slow.. following the settings described in this comment fixed this issue for me. Relevant excerpt below:

  I also mentioned a bug about this.
  I have found a solution (maybe not the best, but it works).

  This only works if you have nvidia drivers installed.
  Open the nvidia settings, and under PowerMizer, change to maximum performance.

  I guess the terminal uses the GPU a ton to render, and when it's lowering clock speeds to save power, it's reducing performance of the terminal.

(from i-r-stuff)

Will the Preferences URL Specification pose a security threat?

I have a strong feeling that this question comes from confusion about what the URL scheme is.

The Preferences URL specification is only a way to open settings applications to the correct location. It is not a way to transmit any kind of data.

Settings URLs look like this:

✔ settings://applications/startup

This URL will only open the settings application to the correct location for the user to take further action.

Never like this:

❌ settings://applications/startup?add-app=malicious%20app%20name

The spec does not intend to describe a way to handle data and you're right that doing so would probably not be a good idea.

TL;DR Settings URLs only open the settings app. They do not transmit data. They cannot change settings. They do not interact with any settings backends like gsettings or keyfiles.

How to roll back a video driver from the command line?

An option to revert back is to use AppCenter > Installed, wait until the nvidia drivers become visible on the top, click on the icon of the one that is installed and then uninstall.

Using command prompt only, sudo apt purge nvidia-* or sudo apt remove nvidia-* . For the first command line option to work probably you have to install purge.


How to configure Internet access ONLY through OpenVPN connection

Also not an expert but long story short, it takes a couple of measures.

I've been using the following tool in combination with NordVPN, which seems to performs these measures automatically.
https://github.com/Chadsr/NordVPN-NetworkManager

I'd advice you to look for clients specific for your vpn provider.

I'm hoping we'll get to a place where this is more integrated into the Network manager itself and or more providers create clients that support linux.


Plank has a hidden settings window for developers/OEMs.

Hold down Control and right click anywhere on the dock
Select "Preferences"
Go nuts

Please be aware that some of these options will lead to less-than-optimal experiences. For example, setting the dock to the Top position will make it impossible to unhide in certain situations as well as cover the time, etc. Some of these features are not completely implemented or don't fully work with other parts of the desktop environment or with certain hardware.


A primer on how Wine works

As it name states, "Wine Is Not an Emulator". Wine doesn't create a Windows environment that .exes can live in: it relies on the use of fake libraries to trick .exes into thinking they're talking with Windows, when really it's just the Linux kernel in disguise. As such, it will be faster than an emulator (ie, Virtualbox) but may still be slower than Windows itself.
The fact that your game runs slower is probably a normal behaviour, but you may be able to configure it to run better.

A few hints:

Update your Nvidia drivers (you seem to have an NVIDIA GeForce GT 630M).
Use OpenGL (probably better FPS but lower graphics quality) with your game.
Look up your game in the Wine Application Database, as they may already have a solution to your low frame rates.

How can we help you further?

Give us your configuration, not just the model of your laptop.
Give us more details on your problem (the name of your game, which version of elementary OS you are running...)


First solution is to type in terminal:
sudo -i /bin/systemctl enable wifi-resume.service exit

If this will not work, then below you have solution.
Second solution is to create a file:
sudo nano /etc/pm/sleep.d/10_resume_wifi

Paste below this:
#!/bin/bash
case "${1}" in
   resume|thaw)
    nmcli radio wifi off && nmcli radio wifi on;;
esac

Ctrl+o to save, Ctrl+x to exit.
Then type in terminal:
sudo chmod +x /etc/pm/sleep.d/10_resume_wifi

to make the file executable
If this will not work put this into the file mentioned above:
#!/bin/bash
case $1 in
    resume|thaw)
        nmcli radio wifi off && nmcli radio wifi on;;
esac

If it will not work, put this:
#!/bin/bash
case $1 in
    post|resume|thaw)
        nmcli radio wifi off && nmcli radio wifi on;;
esac


This is me answering my question: simply place the script in /etc/pm/sleep.d and install pm-utils with sudo apt-get install pm-utils

Elementary Hera is slow on older Mac, Puppy 8.0 is fast as is Mac OS. Is there something I can do (that is not too technical)?

You can install other desktop environment (e.g. JWM, IceWM, or Fluxbox).
Doing so allows you to choose your session before you login by pressing gear icon next to the password text field.

I've tried with fluxbox and this works great so far with about 250Mb memory consumption when idle.


Make sure your window is big enough to fit both text fields.


How can I make the dock's icons smaller?

You can hold Ctrl and scroll over the dock to change the icon size.

There is also a hidden preferences window for Plank. Hold Ctrl and right click on the dock to open a context menu, then select "Preferences".

You can also open Terminal and type in

$ plank --preferences

At the bottom of the window there is a slider to adjust the size of the icons.

Bear in mind, that elementary does not provide icons at arbitrary sizes, so your dock icons may appear blurry at some sizes.


Is there a keyboard shortcut for cycling through windows of the same application?

If you have a US Keyboard Alt+Tab cycles through all the windows.

And yes, to cycle within a tabbed application:

Firefox:Ctrl+tab (forwards) Ctrl+Shift+tab (backwards)
Files: Ctrl+tab (forwards) Ctrl+Shift+tab (backwards)

PS: I think shortcuts can also depend upon the application used.


How do I edit protected .ini configuration files

The area the file resides in requires elevated privileges to be able to modify it.
You can edit is as follows:
From the command line enter:

sudo scratch-text-editor /usr/share/Fakturama/configuration/config.ini

You will be able to edit and save the file this way.


This is the nvidia driver installation question on elementary OS Loki

Install elementary OS as a VM in VirtualBox (OSX host)?

If you want to install

elementary OS as guest on OS X ( host)

In this case, you no need to create a live usb or something to install. The only one you need is .iso file.

Here are instructions to install:

Create Virtual Machine

Open VBox --> Select New --> click on Next until you create VM.
(If you want to do any changes to default options, you can change)
Now we need to install directly from .iso (to avoid creating live usb/cd)

  If you have only live usb, and no .iso then head straight to Note at the bottom)

First place .iso file in a particular location.

Now close Virtual Machine (not VBox) and

open settings --> storage  --> select Adds Optical Drive (green + with disk image)

!

Clicl on  Choose disk  and navigate to location of .iso file.
Select .iso file and click on  Open  and then click on OK
Now close settings and start Virtual Machine

Note:

VirtualBox itself does not support booting from a USB device. But there is a way, for that see my post in Ask Ubuntu.

How to copy old files in old partition to primary partition?

On elementary OS, and every other linux, and every other Unix. Files are organized in a special directory structure.

Type man hier or ask Wikipedia or look at this question to learn about this.

On windows you would not try to put your files under C:\windows\. The same way you would not put your files under /(the root directory) on linux.

On linux it is your home directory where your files live and where you have the right to do pretty much anything. Most of the other directories are system directories and you do not have permissions to write there.


Where can I find applications created specifically for elementary OS?

There are two maintained resources at the moment.

Made for elementary
elementary-apps

The first one contains only applications that are stable or close to being stable. The second one contains those applications as well, but it also contains applications that are early in their development process.

Both of resources include only open source software as there is currently no proprietary applications made specifically for elementary OS.


Nvidia drivers cause freeze when resuming from suspend

First of all, I would check to see if the drivers are correct for your computer.

For this in the terminal enter the following command:

ubuntu-drivers devices

Then with the information of which graphic card you have, enter the repository, update and finally install the driver for your graphic card.

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt install nvidia-XXX (You replace the XXX with your card number.)

Sorry for how I write, my native language is not English.


First, verify your ISO image (check the hash of the image as described here)
Flash the elementaryOS iso again on another USB (if possible).

If that doesn't help, next step is to boot into live session, go to the /boot/efi and rename grubx64.efi to mmx64.efi as answered here.

Another solution I found on this forum, where he used 2 USB keys to boot from one and install from another.


In which programming language elementary OS terminal is written?

The terminal in elementary OS is written in Vala.

You can see information about Pantheon Terminal and even read the source code on its Launchpad page.


I've noticed that who encountered this problem is italian (including me) and thinking about it I've figured out how to solve the problem!

Editing the file (with sudo): /usr/share/applications/gala-multitaskingview.desktop
and replacing the row Icon[it]=vista-multitasking with Icon[it]=multitasking-view
solved the problem!

Ho notato che tutti noi che abbiamo riscontrato questo problema siamo italiani, e da lì mi è venuta l'illuminazione:

Andando infatti a modificare il file (con sudo): /usr/share/applications/gala-multitaskingview.desktop
e sostituendo la riga Icon[it]=vista-multitasking con Icon[it]=multitasking-view
si risolve il problema!
Probabilmente il file relativo all'icona italiana è mancante o chissà cos'altro.


ElementaryOS Loki - window shadow offset

Install dconf-tools

sudo apt-get install dconf-tools

Now start

dconf-editor

Goto org->pantheon->desktop->gala->shadows

You can change values here. Not all windows are effects. Looks like not allow windows can change shadow settigs from this location but many applications do pick up shadow settings from here


There are two solutions that come to my mind:

First one is to use the old kernel. On boot you need to open Grub >> Advanced options. There you can find the older versions.

Second solution is using "xbacklight". It's a command line tool to change the display brightness. For installation:

sudo apt-get install xbacklight

An example to change the brightness to 15 percent:

xbacklight -set 15

That are only workarounds and don't solve the the problem completely.


To install a downloaded .deb file, you have to use the command dpkg.

sudo dpkg -i <distination>/<package>.deb

Or install Eddy, it's point and click for .deb files.

Will the new indicators be released for freya?

The new indicators will most likely be available with the next elementary OS version.


How can I change the background color of the text in the terminal?

It's basically because the permission of the file. Your folder has green background and blue foreground which means that dir is other-writeable(o+w) and not sticky.
If you want to know the color represent what the file type is, you can print dircolors to a file, like this:

dircolors -p > ~/.dircolors

Back to your problem, to change the color of that dir you can remove the write permission of the others group:

chmod -R o-w redentor

You surely want to remove the background color of all dirs inside redentor too, so -R helps you do that recursively.


noacpi must be added in /etc/default/grub then grub must be rebuilt.


Oops, the problem was not coming from Elementary but... from Windows.
I mounted the device manually with sudo mount and it says:
The disk contains an unclean file system (0,0).
The file system wasn't safely closed on windows. Fixing.

It was the same problem for both my usb-key and my hard-disk.
Now everything works fine as before.


Wingpanel clock to display in 12-hour format?

To select the 12-hour format:

gsettings set com.canonical.indicator.datetime time-format 12-hour

To return to the 24-hour format:

gsettings set com.canonical.indicator.datetime time-format 24-hour


black screen with the dock appearing just a few instants

A first auto-answer.
To disable Nouveau driver follow https://linuxconfig.org/how-to-disable-nouveau-nvidia-driver-on-ubuntu-18-04-bionic-beaver-linux

Now Elementary starts with the graphic page.

Nest step, I guess, is to install the correct graphic driver for the hw.


How to upgrade to a newer version of elementary os?

apt dist-upgrade does not upgrade your system to a different release, rather it upgrades existing packages, and installs any new dependencies which may be required by these packages. See my answer here if you want a more detailed explanation.

do-release-upgrade is used to upgrade to a new OS release on Ubuntu, however this does not work on elementary. Instead, elementary currently requires a clean install each time you move between major OS versions (e.g. Freya to Loki).


Where is the printer sharing setting dialog?

First open a terminal and launch system-config-printers or search Slingshot for "System-Config".
When it's open it looks like this:

Right click and check it is shared:

Now we have to change the server settings as per this instruction:

And then check the two check marks Publish shared printers connected to this system and optionally Allow printing from the internet.

Then any computer on the network should be able to see it.


I could resolve the issue by just restarting the network-manager after installing.
sudo service network-manager restart


Can I install elementary os on a atom x5Z8350 and will it run well?

Here are the specs you need:

Recent Intel i3 or comparable dual-core 64-bit processor
4 GB of system memory (RAM)
Solid state drive (SSD) with 15 GB of free space
1024×768 display

https://elementary.io/docs/installation#installation

Your RAM and Hard Drive meet the requirements. Looks like your processor is a Quad-core 64-bit.  I'd say elementary OS will run on your machine.


Installing elementary OS on XPS 15 9550 with Intel SSD in dual boot Windows 10

I looked up your laptop from the Dell website. The HDD is in fact a hybrid drive with a 32 gb ssd inside of the 500 gb mechanical drive. This is the reason that you need the Intel RST driver to work. There is a fix for Ubuntu, and as eOS is a derivative of Ubuntu, it should work. Ubuntu fix for Intel RST


Script or terminal command for enable or disable keyboard backlight

I am using a Toshiba Chromebook 2 with Loki 0.4, I've installed Tweaks and used this to fix my top row key commands "http://www.fascinatingcaptain.com/blog/automate-chromebook-fixes-for-linux/" The brightness keys work however they don't affect anything other than the overlay that increases or decreases the brightness, and the keyboard backlight is broken on top of this.


The elementary apps are still in the process of standardization and I don't believe there are any hooks to easily add the feature you seek without rebuilding your own version of the software from the source. But, hey, if you do it, push the code upstream so that other developers can use it!


How can I disable the rounded display corners Gala plugin?

This was a design decision made by the developers for Freya. There are some settings for Gala (the window manager in elementary OS) that control the corner masking. You can install dconf-editor (sudo apt-get install dconf-editor) to change the settings via a GUI, or use the built-in gsettings command from a terminal. You need to set the enable property to false in the org.pantheon.desktop.gala.mask-corners schema. The gsettings command for this is:

gsettings set org.pantheon.desktop.gala.mask-corners enable false

You can later reset to default with:

gsettings reset org.pantheon.desktop.gala.mask-corners enable
