I'm trying to setup an external monitor to extend my desktop for my Acer Aspire One Netbook running Ubuntu 10.10. It is running an Atom N2600 with an Intel Integrated Graphics Controller.

lspci | grep VGA output is:

 00:02.0 VGA compatible controller: Intel Corporation Device 0be1 (rev 09)

xrandr output is:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 600, current 1024 x 600, maximum 1024 x 600
default connected 1024x600+0+0 0mm x 0mm
   1024x600        0.0*

My external monitor only appears to get a signal when it is connected and I reboot the Netbook, at that time I get a mirrored display.

The resolutions of Netbook's display and external LCD are 1024x600 and 1920x1280 respectively. Xrandr never shows 2 displays.

How can i get Xrandr to see two different displays so that I can configure them?

xrandr: Failed to get size of gamma for output default is not a good sign and is giving me "dejavu" with Set resolution to 1024x600 in eee pc x101CH question.

I've seen several problems like this myself and I've asked Xorg directly for help, to no reply. I think your best bet is to file a bug, using this guide: http://intellinuxgraphics.org/how_to_report_bug.html
