Seems that this was really a hardware limitation, so I'll go ahead and mark it fixed.
You can add resolutions manually using xrandr - see this guide: https://wiki.ubuntu.com/X/Troubleshooting/Resolution#Problem:%20%20The%20LCD%27s%20maximum%20resolution%20is%20detected%20automatically,%20but%20lower%20resolutions%20are%20not%20available Regarding the problem that Screen Resolution doesn't provide a way to add additional resolutions, feel free to file a wishlist bug against gnome-control-center if there isn't already a bug report for that. ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Incomplete => Fix Released -- [RV350 9600] Jaunty : Wrong resolution on external monitor https://bugs.launchpad.net/bugs/323426 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
