OK.... The puzzle deepens.....
"warning: output VGA-1 not found; ignoring"
So, when you just do a "xrandr" on the console of tao there is no section reading something like..
Screen 0: minimum 8 x 8, current 2048 x 1152, maximum 8192 x 8192
DVI-I-0 disconnected (normal left inverted right x axis y axis)
VGA-0 disconnected (normal left inverted right x axis y axis)
DVI-I-1 connected 2048x1152+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
????
When using the --output parameter you need to specify an existing output. In my case there are 3 as shown above.
You don't have a single monitor connected to 2 systems via a KVM do you?
