View Full Version : [xubuntu] Twinview over 2 monitors, Spreads like one monitor

Trying to get Twinview working on my xfce4 desktop,. I have Twinview enabled for my two monitors on one graphics card and a separate X screen for my third on separate GPU. I would rather do xinerama but I cant get composite working so I am doing it this way.

My goal is to get xfce to see that there are 2 monitors and act that way.

I know very little about X. It has always kind of been above my head, and when I get it working I just don't mess with it anymore.

Xorg.conf:
