Public bug reported:

Hello,
on ubuntu 9.04 dual screen worked, but was buggy (the external screen displayed 
only half (vertical split), but the fun was, that putting a window in full 
screen on that external display worked... only window mode had a bug :(

but now i tried my luck on 9.10, and ... it's no more working

my netbook (with intel GMA 950) has a resolution of 1024x600
and the external monitor (a dell one) has a resolution of 1680x1050

so with the System => Preference => display tool (i guess the name, my ubuntu 
is French) i move the screens side by side with clone function disabled.
and then GDM as X won't start


here are the changes that the display tool made in my xorg.cong

SubSection "Display"
               Virtual 2704 1050
EndSubSection

when i start x with startx i receive a message that says "could not add
fb"

so i did a dmesg | grep drm

here is the output :
[    1.695113] [drm] Initialized drm 1.1.0 20060810
