I'm using debian stable but had similar issues with intel card due to the
fact that most of them do not support 3D when using 2 monitors.
You can try disabling 3d and adding following to you xorg.conf (I'm
attaching my one for convenience)
Section "Device"
Identifier "Intel ....."
....
....
....
Option "DRI" "off"
....
....
Option "MonitorLayout" "LVDS,VGA"
....
EndSection
I noticed X is getting better thus enabling dri and so disabling the second
pipe on intel. Perhaps this solves your problem.
