Intel GM965 Dual Monitor Dual Head Multiple X Screen
Hi all,
I need some help configuring multiple monitors on my Dell Inspiron 1525 laptop - the laptop display and a external LCD screen.
This laptop has Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller.
The monitors have the output named VGA1 (for the external LCD screen) and LVDS1 (for the laptop display).
I am able to set up a "dual head" configuration where my desktop is spanned across both the monitors with xranrd as follows:
xrandr --output VGA1 --mode 1440x900 --output LVDS1 --mode 1280x800 --left-of VGA1
I can drag application windows from my laptop display to my external screen and vice-versa.
However, this configuration allows me a single X screen (i.e. display :0.0 only).
I would like to configure multiple X screens (i.e. display :0.0 and :0.1) - one for each monitor.
Based on the results of my google searches, this would not allow me to drag windows from one screen to the other; but that is fine.
I would however be able to do something like:
DISPLAY=":0.1" xclock &
The problem is that I get an error when I startx:
(II) Primary Device is: PCI 00@00:02:0
Requested Entity already in use!
(EE) Screen 1 deleted because of no matching config section.
(II) UnloadModule: "intel"
Output of lspci: http://pastebin.com/tx8A1Qjy
My /etc/X11/xorg.conf: http://pastebin.com/S20S2BLY
My /var/log/Xorg.0.log: http://pastebin.com/grYSxHey
Any help/tips/pointers would be appreciated.
Please let me know in case any more information is required.
Thanks!
