Bug description:
I get logged off from Ubuntu sometimes. There is no error message or
any indication that it is going to log off. The screen goes black, and
after 2-4 seconds, i get presented with the Ubuntu Log On Screen.
There is no clear pattern (or at least if have not noticed any). One
time i am working with Netbeans, another time i am using firefox. This
also means that at present i can not clearly say what package might be
causing this behaviour.
I am fairly sure the problem lies in 12.04 (or more precise - the
combination of 12.04 and the hardware i am using). I do not have the
same problem running 11.04 or 11.10.
