It seems that the reason the 1024x768 mode is not available is that there is something wrong with the EDID information. From XorgLog.txt:
(II) intel(0): Not using mode "1024x768" (bad mode clock/interlace/doublescan) There have been a lot of resolution quirks in newer kernels. It is possible that this has already be fixed in Lucid. Could you give Lucid a try? You can download a LiveCD daily image from http://cdimage.ubuntu.com/daily-live/ and the latest milestone from http://cdimage.ubuntu.com/releases/10.04/ . You may also test the latest kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/ (see also https://wiki.ubuntu.com/KernelTeam/MainlineBuilds). If this has been fixed upstream at all, it should work with the latest drm-intel-next kernel. ** Summary changed: - external monitor resolution 800x600 + [i915gm] max external monitor resolution 800x600 instead of 1024x768 -- [i915gm] max external monitor resolution 800x600 instead of 1024x768 https://bugs.launchpad.net/bugs/480825 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
