Problem with Xinerama in xorg.conf
 
I'm Running Ubuntu 13, gnome or KDE. I have 4 monitors on 2 video cards. I got the xorg.conf configured and working in x-windows. But now I want to enable Xinerama. When I do and re-boot the computer, all 4 monitors are enabled but black. I can switch to tty1 un-enable it, re-boot and system comes up. What I want to be able to do is drag from one screen to the next.

Please help.

Check for errors (lines starting with EE) in /var/log/Xorg.0.log and /var/log/Xorg.0.log.old.

smallpond, I forgot to say that there are no errors in the Xorg.0.log or older files, I wish it was that simple

This post suggests you can do it with DisplayPort monitors.

I can get all 4 monitors working, I can move my mouse from screen to screen. KDE has it's Icon in the right hand corner of ever monitor. I just can not move windows from screen to screen.
