I would like to set dual screen mode on my Fedora 18 XFCE (what I mean is that I want to be able to display different content on every screen). Currently my screens shows the same, i.e. the secondary one is the mirroring primary one. I have a laptop plugged into the docking station with other monitor if that matters.
I actually tried to play with
xrandr but didn't succeed. This command
xrandr --output VGA1 --left-of LVDS1 does what I want but I still can't drag and drop applications between the screens
