There have been issues with X crashing upon log out. To properly triage this, the Ubuntu X team would need a copy of /var/log/Xorg.0.log.old and a copy of the output of the command "lspci -vvnn" attached to the bug. (Preferably you could test from Kubuntu 9.10, to see if it still happens with the new drivers)
As a separate issue, KDM doesn't restart X on these logout crashes, leaving you with the blank screen symptom: bug 432521. ** Package changed: kdebase-workspace (Ubuntu) => xserver-xorg-video- intel (Ubuntu) ** Changed in: xserver-xorg-video-intel (Ubuntu) Importance: Undecided => Medium ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Incomplete -- KDM Log Out = Blank Screen https://bugs.launchpad.net/bugs/415482 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel 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
