I have tried everything I can think of and can't get a multi monitor setup working. Can anyone please point me in the right direction?

VGA-0 is my LG, and LVDS-0 is my laptop screen. They are both working properly right now with no xorg.conf enabled during boot. HDMI-0 is connected to the Samsung and is black. DP-0 will be used with the second LG once I get 2 working!

My /etc/X11/xorg.conf

Is anybody else able to simultaneously use the VGA/DP/HDMI ports on the Asus G75VW with Ubuntu 12.10? I can still only use 1. –  Shaun Dec 19 '12 at 7:52
