While there have been kernel updates, I didn't think the introduction of this problem corresponded with an update. Indeed, I've just checked and this behaviour occurs with 2.6.31-1-generic, too. > > A piece of information which may be useful to the developers is whether > this also happens without kernel mode setting.

This does not appear with KMS disabled. I'll get those logs. ** Attachment added: "Xorg.0.log" http://launchpadlibrarian.net/28904468/Xorg.0.log -- [GM45] Default 60Hz display mode drives LVDS incorrectly https://bugs.launchpad.net/bugs/398026 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
