Running: Ubuntu Studio 12.10
Platform: Acer Aspire One AO751h
Screen: 1366x768
Video: Integrated Intel Graphics Media Accelerator 500

with Dual Monitor:

Monitor: AOC 22
Res: 1920x1080

Ran: $ xrandr --output VGA-0 --mode 1920x1080 --right-of LVDS-0

Got: $ xrandr: screen cannot be larger than 2048x2048 (desired size 3286x1080)

There is no initial xorg.conf file to edit and they changed the location /xorg.conf.d/ to /usr/share/X11 in 12.10.

Please advise me on the best way to get the virtual display (extended desktop) running properly. I use this setup for work and any help would be appreciated
