You may have accidentally removed some packages (or some dependencies which caused the package to uninstall). In any case, you may try installing (or re installing) the package ubuntu-desktop. Correct any accidental package uninstallation by:
sudo apt-get install ubuntu-desktop
Uninstall and then reinstall System Settings (unity-control-center) from the Ubuntu Software Center application.
Or run this command in terminal
sudo apt-get remove unity-control-center
sudo apt-get install unity-control-center
Your Gnome-Control-Center might need reinstalling. Open your terminal and enter these commands:
sudo apt-get update
sudo apt-get install --reinstall gnome-control-center
And then the commands for opening the display and system settings, respectively, would be:
These commands will change the desktop ...
I had exactly the same problem - same icons missing as well. I had stupidly uninstalled gnome-bluetooth, and nothing was fixing it. So I did what user282306 (r00t) suggested -
sudo apt-get install ubuntu-desktop
And I've got them all back again.
Kudos @user282306 (previously r00t) for the suggestion.
And if you are trying to do this with Ubuntu 18.04, try this:
sudo apt-get remove gnome-control-center
sudo apt autoremove
sudo apt-get install gnome-control-center
This is because Ubuntu decided to switch their user interface from Unity to Gnome.
Finally I found the option. I had to install Tweaks and go to
Keyboard and mouse > Additional layout options > switching to another layout
The strange thing is that there is that the default shortcut super+space was not selected in that window, only the alternative shortcut.
dconf-editor uses schema path to show settings data tree. Same structure used to store data in GVariant database.
gsettings (from glib-2.0) uses schema id to show/get settings data. Same way as any other application should do which uses GSetttings API.
It's up to the application developer to set both as he/she would like. (with some restriction for canonical ...
You have to install a few packages first with:
sudo apt install openvpn network-manager-openvpn network-manager-openvpn-gnome
then, restart network-manager
sudo service network-manager restart
and try again. If it doesn't work, then try logging out and back in, if not, then try rebooting.
If reinstalling ubuntu-desktop still doesn't cut it for you, you may be accessing system settings in a wrong way. Try to open them directly from a terminal (rather than a bogus shortcut like I was):
Using dconf editor
To disable alert sounds on Ubuntu 19.04 you could install dconf editor, either from terminal or from activities/software center. From terminal
sudo apt install dconf-editor
Next, launch dconf editor and navigate to org/gnome/desktop/sound/event-sounds and flip the switch to off - alternatively, click on event-sounds and set custom value ...
This solution did not work for me for Ubuntu 18.04. But as I executed
pactl load-module module-detect
the missing built-in Audio Analog Stereo suddenly appeared in the sound settings menu. As I chose it, I was able to hear the sound.
If you want this setting permanent, add the line load-module module-detect to the default modules in /etc/pulse/default.pa
I've found 2 ways to do this.
from the command line
dconf write /org/gnome/desktop/interface/clock-show-date 'true'
Install gnome-tweaks and in it there is a setting to show the day/date along with the time in the top bar. To install, do:
sudo apt install gnome-tweak-tool
After the install, when you run tweaks, you will see on the far left column "...
This issue was resolved for me by (re-)installing unity-control-center
apt-get install unity-control-center.
I didn't want to re-install the whole ubuntu-desktop because it was going to install a bunch of packages I didn't want/need and use another 100MB of space.
Compared to just 4MB with unity-control-center
After a long struggle I have been able to fix this with the help of previous answers and trial and errors.
I booted into Advanced mode while booting Ubuntu press F2 when you see grub2 bootloader. On some systems you may need to press Shift to get to advanced boot menu.
In my case since I was in a VMware Workstation environment I pressed Shift or F2 to get to ...
Strange, but I found answer first!
$ xrandr --output $monitorName --rotate $direction
where $monitorName can be found in output of
and $direction is left for counter-clockwise or right for clockwise.
Edit: Using grep, it is possible to write a script like this:
descr=$(xrandr | grep "$screen")
if echo "$...
I found the answer: sudo apt-get install ubuntu-desktop
This gave me the following:
The following NEW packages will be installed:
apturl apturl-common nautilus-share software-properties-gtk ubuntu-desktop
I have no idea how these got deleted, but they're back now.
The Language Support utility is provided by the language-selector-gnome package
sudo apt-get install language-selector-gnome
Once you install that package, you'll see the language option in the System Settings again.
GNOME's background customisation option is very limited. Along with system background images and solid colours, it allows the user to choose images only from Pictures, not even from any subfolder of Pictures. You may do one on the following:
Place the image you want to set as background in Pictures folder, not inside any subfolder.
Recommended option: Use ...
I managed to solve this, although not a optimal solution, it'll work.
I installed PulseAudio Volume Control. Then went to "Configuration" and under the correct sound card, I chose the correct output (Analog 5.1).
Then it shows up in sound settings again. Although, if I change the device in Sound Settings, I sometimes have to open PulseAudio Volume Control ...
First reinstall locale package:
sudo apt --reinstall install locales
Open this file:
sudo nano /etc/locale.gen
Find this line: # de_DE.UTF-8 UTF-8, uncomment it so it's now: de_DE.UTF-8 UTF-8. Save the file and run:
see if you have German now.
