Random log off in Ubuntu 12.04.1 LTS

[Kirils Solovjovs]

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.

This first started happening to me not more than a week ago.

Symptoms are very similar to https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/980519

I am using Module fglrxdrm: vendor="FireGL - ATI Technologies Inc."

My system info is attached here: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/980519/+attachment/3344430/+files/lshw.txt

Are there any changes recently commited that could have caused this?

I am using the up-to-date versions.
