The weird result

When I plug in a external monitor to my netbook I get this rather perculiar result, it persists until I unplug the monitor.

This is on Arch Linux, pacman reports the driver as xf86-video-intel 2.17.0-2

relevent lspci:
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

If you need any further details, just tell me. :)

Are you attempting to use a GL-based compositing WM with a desktop wider than 2048 pixels?
Comment 2 Selig Arkin 2012-03-05 11:35:10 UTC
That may be the case, this is with gnome-shell -- the screenshot is 2400x900 so that would seem to indicate that is the problem

Problem is easy to hit with bdw and a standard desktop configuration.
