Which version of xrandr do you have installed? Those don't seem to even
options in the FC7 one I have:
continuity> xrandr --help
usage: xrandr [options]
where options are:
-display <display> or -d <display>
-help
-o <normal,inverted,left,right,0,1,2,3>
or --orientation <normal,inverted,left,right,0,1,2,3>
-q or --query
-s <size>/<width>x<height> or --size <size>/<width>x<height>
-r <rate> or --rate <rate>
-v or --version
-x (reflect in x)
-y (reflect in y)
--screen <screen>
--verbose
continuity>
I've got a laptop with I945 video and I tried several variations and it
doesn't seem like my laptop even see the other monitor when I connect
it. The most telling is this error:
continuity> xrandr --verbose --screen 1 --size 1920x1200 --orientation right
Invalid screen number 1 (display has 1)
continuity>
Thanks,
