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

    Video card, probably driver used and similar info would be helpfull... – IBr May 27 '13 at 6:45
  • As I recall you can use the "Display" or "Monitor" tool found under the settings menu. I also recall that I needed to set some offset to align the screens in the way you want. – Kotte May 27 '13 at 6:48
  • @IBr I got Nvidia with nouveau drivers – Petr Mensik May 27 '13 at 7:44
  • Don't you just use the nvidia configuration tool to set these up /usr/bin/nvidia-settings? yolinux.com/TUTORIALS/images/… – slm May 27 '13 at 7:54
  • I think if you are going with nouveau, you can use xrandr tools and/or xinerama. I think this could be helpfull, though not fedora specific, but it should work: wiki.archlinux.org/index.php/… – IBr May 27 '13 at 10:30

I finally solved it with xrandr --output LVDS1 --left-of VGA1, this works as I expected.

  • Old thread but I would like to point out that if you are using virtual box the outputs will be VBOX0 and VBOX1 instead of LVDS1 and VGA1. – atomSmasher Dec 16 '15 at 20:29
