I am having random freezes (rarely) in Ubuntu 10.04, did in 8.04 to. I have been over at the Ubuntu forums try to figure this out with the others at the Ubuntu forums. This is a common prob. there is a topic about random freezes with 101 pages, no one can connect a source. I just had a thought a few ago, it is crazy, but could Gnome be the prob.? I have 2.30.2.
