Public bug reported:

Binary package hint: xserver-xorg-video-intel

I run a dualhead configuration with an external LCD (1680 x 1050) and
the internal laptop display (1280 x 800). If I put the laptop to suspend
with this configuration it shows the following behavior after waking up:

  * The first 1280x800 pixel of the desktop background and the icons,
which are shown on the external display, are repeated on the internal
display. So the internal monitor "clones" a segment of the external
monitor.

  * The mouse pointer is NOT cloned. It can be moved normally across
both screens.

  * Windows placed on the external monitor are NOT cloned to the
internal screen.

  * Windows disappear if they are moved from the external to the
internal screen.


The configuration can be fixed by de-activation and subsequent re-activation of the external screen using xrandr.

I'm using an Intel GM965 controller and Ubuntu 9.10alpha4. Compiz is not
enabled. The accelleration method is set to UXA. The bug described here
did not occur in prior versions of Ubuntu.
