[ubuntu] 12.10 errors ??

view story

http://ubuntuforums.org – Last week i installed 12.10 on my old Vista PC. It seemed to install ok, but since doing all the updates i often get program crashed & error messages. I managed to screen shoot a few as in the attachments. Can anyone help as to what is crashing & why....and can i do anything about it ?? One even happened as i was writing this report out :( Compiz & Unity seem to get mentioned a lot in the errors. Any advice or help would be GREAT :p Attached Images Screenshot from 2013-01-14 15:56:08.jpg (74.0 KB) Screenshot from 2013-01- (Hardware)
