Panel and Launcher are missing in Ubuntu 13.04

Question

i have upgraded Ubuntu desktop from 12.10 to 13.04. Since then I can't see the Panel or Launcher, but I'm able to open the terminal using the keyboard shortcut Ctrl+Alt+T.

When I use the Guest login there is no such problem. I am facing the problem only with administrator account. I have tried this Launcher, top Panel, and window decorations missing after 12.04 upgrade, but I couldn't find the result.

Answer 1

This worked for me:

dconf reset -f /org/compiz/ 

then enter:

unity --reset-icons &disown

Answer 2

Try deleting ~/.cache or~/.gconf. Realize however that if you made any edits to the system using dconf (or gconf)-editor, they will be reset.

Another alternative is to also delete ~/.config but that would reset any and all application preferences throughout Ubuntu for your user.

Answer 3

try this:

sudo apt-get purge fglrx lightdm && sudo apt-get install lightdm ubuntu-desktop

and then reboot

Answer 4

This happened to me and I moved the .config directory and re-logged in and it is working fine for me now.

mv ~/.config ~/.config_old

I had to use the old Ctrl+Alt+F1 to get to a terminal because the guest terminal wouldn't allow me to sudo for some reason. Then I did a Ctrl+Alt+F7 to get back to my login session.
