I could reproduce it with Karmic. Attached are Xorg.0.log and a screenshot.
The procedure was: boot karmic, disable laptop minotor with gnome- display-properties and enable 1600x1200 on VGA connected monitor. I also tried to boot with montor unplugged and plug it in. Unsurprisingly both yielded the same result. ** Attachment added: "Xorg.0.log" http://launchpadlibrarian.net/29082243/Xorg.0.log -- [i855] Resolution change breaks graphics in Intel 855GM https://bugs.launchpad.net/bugs/393031 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
