Hi, More information about this issue:
- still happening on an up-to-date Natty - Problem *does not occur* if gnome-display-properties is running at the time - The exact symptoms have changed a little, but still shows the same inability to properly set the external monitor - With gnome-display-properties running, cycling through modes with Fn+F7 looks like this (in order): Mode Internal External ------------------------------------------------ Spanning Desktop On On Clone Mode On Broken Internal Only On Off External Only Off On Spanning (again) On Broken If gnome-display-properties is running, it works properly: Mode Internal External ------------------------------------------------ Spanning Desktop On On Clone Mode On On Internal Only On Off External Only Off On Spanning (again) On on This is on a projector, which doesn't support many modes, so "broken" is basically "black". When run on a fairly flexible external monitor, I noticed that the resolution/refresh as reported by xrandr does not match the actual resolution of the monitor. In the attached photo, you'll see output of xrandr (white on black) saying the monitor is 1920x1200@60Hz, but the monitor's status menu says it's running 1600x1200@60Hz. The GNOME desktop believes that the monitor is 1920 pixels wide, so even though there's a picture on the monitor, much of it is missing.

External monitor is set to incorrect resolution when it's the only active display. xrandr output does not match resolution of external display that is actually set. E.g., xrandr shows "1920x1080@60Hz", but monitor status menu shows 1360 x 768 @ 60Hz, which it does not support. ## Environment - Thinkpad X220 (T61 also fails) - External monitor attached ## Steps to reproduce: - connect external monitor to ThinkPad X220 (or X61) - press Fn+F7 to cycle through modes - on External Monitor Only mode, compare resolution of external monitor as reported by xrandr and the monitor itself.
