I'm new to Ubuntu..
I'm not sure what just happened, but the screen just went black with the text: Ubuntu 11.10 "my computer name" tty4
and I was asked to log on.
It happened when I closed Chrome (Alt+F4). This is the second time it has happened, and I cant make it go away :) Even if I log on. Only thing that works is to press Ctrl+Alt+Delete, which makes my PC restart.
Any idea what is causing this?
