summary "Screen Resolution applet's Virtual line can break compiz"
So, this isn't a compiz bug. The problem is that your Intel card can't
do DRI with a framebuffer (total display resolution of all monitors
combined) greater than 2048 in either dimension. Since the combined
x-resolution of your two screens is 2760, you're hitting this limit.
Opening a task against gnome-control centre (where the Screen Resolution
capplet lives). It would be nice if the capplet could mention this when
writing the Virtual (framebuffer size) line to your Xorg.conf.
Something like "This hardware/driver does not support 3D with a screen
size > 2048x2048. Enabling this monitor would expand the screen size to
$BAR. Do you want to continue", sort of thing.
