The relevant output of my xrandr configuration:
xrandr -q
Screen 0: minimum 320 x 200, current 2304 x 1024, maximum 8192 x 8192
LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis)
VGA1 connected 1280x1024+1024+0 (normal left inverted right x axis y axis)
Just as an examle; let's say I would launch gvim from the commandline, how could I force the application window to be displayed on output VGA1?
As a desktop environment I am using Unity with compiz enabled. Maybe there's a way to do this within compiz if I can't do it straight from the cli (which I would prefer)?
