it's possible with xrandr, not xinerama (which we don't support)

if you run the ubuntu UI, just go in the 'display/monitor settings'
and uncheck 'mirror' option. you can move the relative display
position as well, and/or resize.

note that we have a h/w limit of 2048x2048, for the overall virtual framebuffer.

if you don't have UI, you can use the command line too. something
along these lines should work:

xrandr --output VGA --mode 1280x1024
xrandr --output LVDS --mode 1024x768
xrandr --output VGA --right-of LVDS

of course you need to use the appropriate connector name.
