Oh, right, I completely forgot I had to change xorg.conf Also need to be noted that if you want to use desktop effects (compiz) you must not exceed 2048 in any direction. In my case putting them side by side makes it impossible to run compiz as 1024+1280 = 2304 > 2048 for me. (Virtual 2304 1024) I tested that putting one above the other works with compiz as 768+1024 < 2048 (Virtual 1280 1792 and xrandr --output VGA --above LVDS) Simo. -- | Simo S Sorce | | Sr.Soft.Eng. | | Red Hat, Inc | | New York, NY | -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
