Well I thought I’d have another play with Nouveau the open source driver for nVidia GPU’s, as it been a while since played around with them. Since the last time I played with Nouveau it was very buggy and unstable and 3D support was even worse, but I very surprised that there is some 3D support via Gallium3D.
Anyways this how I setup my xorg.conf for dual head setup with nouveau under Debian testing (wheezy):
Section "Monitor"
Identifier "monitor0"
Option "PreferredMode" "1920x1080_60.00"
EndSection
Section "Monitor"
Identifier "monitor1"
Option "PreferredMode" "1440x900_60.00"
Option "RightOf" "monitor0"
EndSection
Section "Device"
Identifier "device0"
VendorName "nVidia Corporation"
BoardName "GeForce GT 220"
Driver "nouveau"
Option "Monitor-DVI-I-1" "monitor0"
Option "Monitor-VGA-1" "monitor1"
EndSection
Section "Screen"
Identifier "screen0"
DefaultDepth 24
SubSection "Display"
Depth 24
Virtual 3360 1080
EndSubSection
Device "device0"
EndSection
Section "ServerLayout"
Identifier "layout0"
Screen "screen0"
EndSection
At the moment I am very happy with Nouveau and going to keep using it till it borks it again 🙂
Also if you not want to go through the hassle of xorg.conf you could run or put this in your session startup file, example this what I used for testing with ~/.fluxbox/startup
$ xrandr --output DVI-I-1 --mode 1920x1080 --pos 0x0 && xrandr --output VGA-1 --mode 1440x900 --pos 1920x0 &
The above does the same as the above xorg.conf configuration.
