Yes, sounds likely to be a broken monitor emitting incorrect EDID information. It looks like you're using a configuration where modesetting is done by the kernel rather than X so reassigning to the kernel. Probably there is a quirk for your monitor in the xserver which wasn't taken into the kernel.
The steps for troubleshooting this class of problem are well documented at http://wiki.ubuntu.com/X/ on the Troubleshooting and Quirks guides; in particular you should gather an EDID dump. The docs explain some common issues with monitor EDID that you can examine. ** Package changed: xorg-server (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- Samsung SyncMaster 920N monitor resolution not correctly detected https://bugs.launchpad.net/bugs/533639 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
