Linux desktop not working

Can’t start ubuntu-desktop after upgrade to 18.04

After the restart step of upgrading Ubuntu to 18.04, tty is opening instead ubuntu-desktop. And when I enter my login name and password, I am still in the tty. This is happening again in every restart. How can I start the graphical desktop as normal?

Which desktop environment are you selecting from the gear drop down menu next to the Sifn In button? The first four options don’t work for me. Only the bottom option (Unity) works for me.

Using journalctl -f in a terminal and then trying to login again, I was able to see it barfed on a corrupted notifications file. Deleting this file took care of the problem. Possibly caused by a bad shutdown? I’m thinking there might be more such problems. Discovered the solution here: gitlab.gnome.org/GNOME/gnome-shell/-/issues/1552 (Using tmux to scroll back in the terminal was critical.)

Try logging in to your default desktop environment from the tty virtual console.

1. Open a text-only virtual console by using the keyboard shortcut Ctrl + Alt + F3 .
2. At the login: prompt type your username and press Enter .
3. At the Password: prompt type your user password and press Enter .
4. Now you are logged in to a virtual console, and you can run terminal commands from the console.

Run the following command:

sudo systemctl start graphical.target 

If that doesn’t work, switch the login display manager from gdm3 to lightdm.

sudo apt install lightdm sudo dpkg-reconfigure lightdm sudo reboot 

sudo dpkg-reconfigure lightdm will open up a new window allowing you to select lightdm as the default login display manager. Use the arrow keys to select lightdm and press the Tab key to put the focus on and press Enter . Then reboot by running this command: sudo reboot

If that doesn’t work either see if you can at least switch to text mode (for troubleshooting purposes) with no GUI stuff like the X server running.

sudo systemctl start multi-user.target

Ubuntu desktop icons not working

None of the above worked for you then you have to upgrade your Ubuntu for example from Ubuntu 16.04 to Ubuntu 18.04 or Ubuntu 18.04 to Ubuntu 20.04. Don’t worry your data will be safe.

First, open terminal by CTRL+ALT+F1

There are a few things that could be causing the issue with the icons on your Ubuntu desktop not working.

1. Corrupted icon cache: You can try rebuilding the icon cache by running the command “gsettings set org.gnome.desktop.interface icon-theme ‘Name_of_icon_theme’” in the terminal, replacing “Name_of_icon_theme” with the name of the icon theme you’re currently using.
2. Missing dependencies: Make sure that you have all the necessary dependencies installed for the icon theme you’re using. You can install them using the command “sudo apt-get install [dependency]”
3. Permission issues: Check the permissions on the icon files and folders. They should be set to 644 for files and 755 for directories.
4. Conflicting theme: If you have installed multiple icon themes, it may be causing conflicts. Try uninstalling all but one icon theme to see if that resolves the issue.

If none of the above solutions work, you can try reinstalling the desktop environment or reinstalling ubuntu.

If the icons on your Ubuntu 22.04 desktop are not showing, there are a few things you can try to troubleshoot the issue:

3. Check for missing dependencies: Some icon themes may require additional dependencies to work correctly. Make sure that you have all the necessary dependencies installed for the icon theme you’re using.
4. Check for Gnome-shell extensions: Some gnome-shell extensions can cause the icons not to show. Try disabling or uninstalling the extensions and see if that fixes the issue.
5. Delete icon cache files: Sometimes the icon cache files may get corrupted, try deleting the icon cache files located in ~/.cache/icon-cache and ~/.local/share/gvfs-metadata

If none of the above solutions work, you can try reinstalling the Ubuntu desktop environment by running

sudo apt-get install --reinstall ubuntu-desktop

1. Check for updates: Make sure that you have the latest updates installed for your system. You can check for updates by running the command in the terminal.
