I have the same problem on a IBM Thinkpad T43 (Model 2668Y3U) with an ATI Radeon Mobility X300 with a fresh install of Gutsy. I had the same problem on Feisty.
I thought it was a GPU temperature issue but this not the case: I reached 67 Celsius during glxgears but I couldn't reproduce the problem. I experienced freezes when CPU and GPU temperatures were under 50 Celsius. Disabling desktop effects resolves the problem... I'm, sadly, thinking that enabling compiz by default wasn't a brilliant idea... I've attached my lspci -vn output. ** Attachment added: "lspci.log" http://launchpadlibrarian.net/10064302/lspci.log -- X freezes when compiz is enabled on ATI cards https://bugs.launchpad.net/bugs/108527 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
