Just started my Gnome Ubuntu box. After logging in, this error surfaced.
In the 'report a problem' interface, it showed me the Xorg error.
However I think this might has to do with Compiz. I noticed the following message in the error summary display:
No value set for `/apps/compiz-1/general/screen0/options/active_plugins'.
Then I searched the problem on the internet. Found a post which I thought was a good starting point for the investigation:
http://askubuntu.com/questions/74313/list-and-enable-disable-compiz-plugins-on-command-line
Turns out compiz is not even installed, i checked this with aptitude.
