Unity – Sidebar Disappeared on Ubuntu 14.04

desktop-environmentsunity

For some reason the sidebar and the top bar disappeared on my Ubuntu 14.04. Ctrl+Alt+t does not start a terminal. I tried to remove .config and .cache/compizconfig-1, I tried to restart and reinstall unity, but to no avail.

I have some files on my desktop. If I open them, the corresponding application starts but the menu at the top does not show.

I also tried to use ccsm as suggested here Unity doesn't load, no Launcher, no Dash appears but it did not work.

  1. Open a tty terminal: Ctrl+Alt+F1.

  2. Next, log into your account and run the following commands:

sudo rm -rf ~/.cache/compizconfig-1
sudo rm -rf ~/.compiz
sudo rm -rf ~/.Xauthority
sudo dconf reset -f /org/compiz/
setsid unity
sudo reboot
