I have an Acer laptop with a port replicator, the Easyport IV.
- Acer laptop, Travelmate 8172
- Intel HD graphics
- Ubuntu 12.10
I have two VGA ports. One directly on my laptop and one on my easyport of course.
Most of the times I am forced to use the VGA socket on my laptop, which somehow defeats the purpose of a having port replicator.
xrandr -q doesn't list it as a different device of course. Also I don't get a
udev signal. Sometimes, on rare occasions it will mystically pick the VGA on my Easyport, but I can't trigger that.
How can I choose the VGA output on my port replicator?
