Looks like you might have the same problem I have -- the new
driver/server has trouble reading EDID from the external display.
My xorg.conf contains this:
Identifier "Dell TFT"
Modeline "1680x1050" 149.00 1680 1760 1944 2280 1050 1050 1052 1089
Identifier "Default Screen"
Device "Intel Corporation Mobile Integrated Graphics Controller"
Monitor "Generic Monitor"
Option "monitor-VGA" "Dell TFT"
Virtual 1680 1050
Which tells the intel driver to add the specified modeline to the list
of valid modes on the VGA output. With this I can randr up to 1680x1050
on the external display if I turn off the local panel.
