I just rebooted my computer and have no interface (except my desktop background and desktop files), which means no unity and no notification bar.
Also, Ctrl+Alt+T doesn't work.
Ctrl+Alt+F1, does however.
If anyone has a clue, I would be very grateful! I really want to get into Ubuntu, but it feels so fragile and easy to break :(
I used Ctrl+Alt+F1 to get into TTY1, logged in with my username and password, and then typed :
sudo apt-get install ubuntu-desktop
It rapidly removed Virtualbox which i had just installed. Seems Virtualbox was behind the issue.
sudo reboot and i was ready to go again.
Thank you @Radu for your help.
Now I just have to figure out why Virtualbox broke ubuntu in the first place ...
Go in tty1 (Ctrl+Alt+F1), login with your username and password and run this comands: that reset compiz and unity:
sudo dconf reset -f /org/compiz/
sudo unity --reset-icons &disown
After these, restart your system and should work like a charm:
sudo reboot
