OKay, I've been fiddling around with a dual head configuration with
Ubuntu 9.04.
Initially I was using the default configuration and these xrandr commands:
xrandr --output TMDS-1 --auto
xrandr --output LVDS --auto
xrandr --output LVDS --left-of TMDS-1
I could have probably just added these to my startup scripts and been
done with it...but I wasn't having any of that.
So I fiddled with the xorg.conf file and came up with this:
Section "Monitor"
=09Identifier=09"VGA"
Option "RightOf" "LVDS"
EndSection
Section "Monitor"
=09Identifier=09"LVDS"
EndSection
Section "Monitor"
=09Identifier=09"TMDS-1"
Option "PreferredMode" "1680x1050"
Option "RightOf" "LVDS"
EndSection
Section "Device"
=09Identifier=09"intel-945"
Option "Monitor-LVDS" "Laptop LCD"
#=09Option=09=09"UseFBDev"=09=09"true"
EndSection
Section "Screen"
=09Identifier=09"Screen0"
=09Monitor=09=09"LVDS"
=09Device=09=09"intel-945"
=09SubSection "Display"
=09=09Virtual=092960 1050
=09EndSubSection
EndSection
I've added some more info below about the video configuration in case =20
it might help
Notice the Option "PreferredMode" "1680x1050". That was added because =20
the second screen (for the intel driver at least) tries to be set at =20
the same size as the initial screen (or the next one down).
This line allows the screen to be defaulted to it's biggest size.
xrandr -v
