I can't see any EDID information in the output of `xrandr --verbose` or Xorg.0.log. What are the correct resolution of your internal laptop monitor (1200x800?) Would it be possible for you to connect your external monitor (1440x900) via DVI and get the Xorg.0.log for that? Since this was working in an earlier version of ubuntu, do you have the possibility to start from an Intrepid LiveCD and attach `xrandr --verbose` output and Xorg.0.log (preferably with the ModeDebug option set)? Are you using your two monitors in mirrored mode or as an extended desktop? Newer versions of xorg (or the driver) rely more heavily on the EDID information provided by the monitor that before. This is a standard that virtually all monitors have supported since around 2001. Unfortunately, many Vaio laptop panels don't support this, and these are the only monitors I know about that don't. Occationally, the EDID information in some models are slightly wrong, but in those cases it is possible to make xorg work around it. Without any EDID information, it is not possible to figure out what is connected at all. -- [i945] i945 don't recognize 1440x900 in ubuntu jaunty https://bugs.launchpad.net/bugs/376722 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
