[i915gm]all displays fail to output applications when virtual is set

[Sami Haahtinen]

Binary package hint: xserver-xorg-video-intel

Display Preferences application writes the following to xorg.conf when mirror display is disabled:

Section "Screen"
        Identifier "Default Screen"
        Monitor "Configured Monitor"
        Device "Configured Video Device"
        SubSection "Display"
                Virtual 2680 1050
        EndSubSection
EndSection

This combined with the latest xserver-xorg-video-intel causes both displays to activate but no applications are shown on either of the displays. For example, in gdm login the mouse cursor is shown on both screens yet both screens remain otherwise black. (the gdm login screen is not displayed).

I'm assuming that this isn't caused by gdm since if i enter my username and password to the blank screen, i can hear the login sound playing.

Does this still occur if you have the external monitor disconnected (but the Virtual set as above)? With the external monitor disconnected, does it still happen if you reduce the first number to 2049? And to 2048?
