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
  • Thanks a lot! sudo rm -rf ~/.Xauthority was the only thing I had not tried. – Pantelis Sopasakis Aug 7 '17 at 19:40

You just need to open Settings → Dock → Position on Screen and choose one of them. The icons will reappear.
