Hi guys,

Does anybody have any pointers on how I get an extended desktop working on Kubuntu 9.10? (ATI x700)

I can get it mirrored quite easily - System settings > Display > Size and Orientation.

But if I click on multiple monitors I get: "This module is only for configuring systems with a single desktop spread across multiple monitors. You do not appear to have this configuration."

So, I run
xrandr -q

Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280
VGA-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1152x864 60.0
1024x768 60.0*
800x600 60.3
640x480 59.9
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 330mm x 210mm
1280x800 60.1*+
1280x720 59.9
1152x768 59.8
1024x768 59.9
800x600 59.9
640x480 59.4
DVI-0 disconnected (normal left inverted right x axis y axis)

__________________________________________

So, I run the following:


xrandr --output VGA-0 --off


xrandr --output LVDS --auto --output VGA-0 --auto --right-of LVDS

And I get told that "xrandr: screen cannot be larger than 1280x1280 (desired size 2304x800)"

So I have manually creates an xorg.conf file, and added "Virtual 2304 800" so the relevant section reads:
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
Virtual 2304 800
EndSection

Restarted the computer, but I still get the same result... any pointers?!
