I upgraded xserver-xorg-video-ati to 1:6.12.192-2 (from debian, build from src on ubuntu) - problem persisted..
when I upgraded kernel to 2.6.33.1 (config from 2.6.32-17.26 generic flavor) - it seems, no more crashing or freezing... I will try testing more extensively later, to make sure 2.6.33.1 solves the problem... p.s. I guess it is the time to notify kernel teem -- [X700] KMS, amd64: reboot or freeze while trying to launch system > preferences > appearance https://bugs.launchpad.net/bugs/544741 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
