Works too on my old Dell C400 with a VGA compatible controller: Intel Corporation 82830M/MG Integrated Graphics Controller (rev 04) Good thing is I have no issues on login screen but I'm using /etc/X11/xorg.conf.d/20-intel.conf not /etc/X11/xorg.conf to store my settings. This configuration resolved (at least for me) a bug with xserver-xorg-video-intel package too: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1186800 F. -- Mailing list: https://launchpad.net/~lubuntu-qa Post to : lubuntu-qa@lists.launchpad.net Unsubscribe : https://launchpad.net/~lubuntu-qa More help : https://help.launchpad.net/ListHelp
