I'm getting the same problem, but i don't have compiz or ati. It won't _let_ me use compiz, even though it was working in feisty.
Symptoms are the bad ones: Everything freezes for no apparent reason, with no apparent regularity and with no warning. Mouse doesn't work, neither does ctrl+alt+backspace. I left it frozen for 2+ hours once just to check if it would start back up on its own, but no such luck. My Setup: Some HP from January. Intel Core2duo Intel Integrated graphics (Intel Corporation 82G965 Integrated Graphics Controller (rev 02) ) Software: Like i said, no compiz. Everything installed from repositories. The only config that i've done that i could even imagine having this effect is that when i installed imwheel i touched xorg.conf, but nothing visual, just the mouse stuff.
