I also have some stange problems with the intel driver and external output.

It all started the other day when I tried to make GDM show in a higher resolution. I tried doing "xrandr ---output LDMS --auto --output TDMS-1 --auto" in the end of /etc/gdm/Init/Default. This seemed to work fine, restarted, resolution was correct on both monitors, pulled out the external screen, restarted, everything seemed to work fine. Then came the choke - putting back the external screen and restarting resulted in picture on the laptop screen only. Since then I revoked the oneliner and tested again, but the problems now seem to be permanent, I can't get display on my external monitor back.

I ran xrandr and only got

Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280
VGA disconnected (normal left inverted right x axis y axis)
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 261mm x 163mm
   1280x800 59.9*+ 60.0
   1280x768 60.0
   1024x768 60.0
   800x600 60.3
   640x480 59.9
TV disconnected (normal left inverted right x axis y axis)

That is, no TDMS-1 detected at all!

I'm really at a blank here....

Oh by the way, If you think this i separate bug please feel free to open a new one.
