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.

dconf reset -f /org/compiz/

then enter:

unity --reset-icons &disown

this works, but keep in mind that it will reset the launcher! – maephisto Aug 14 '13 at 10:32
this did not work for me. The menus appeared for a second, after the restart, then disappeared. – dranxo Oct 31 '13 at 00:20
works when I run like that dconf reset -f /org/compiz/ && unity --reset-icons &disown at the second time. – Claudio Santos Dec 17 '13 at 22:30

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.

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.

This will erase user configuration files for A LOT of programs. Don't do it unless you are sure. I would downvote but I don't have enough reputation. – YuppieNetworking Jul 18 '13 at 10:37

Deleting ~/.config did the trick for me. – Bram Aug 13 '13 at 03:42
