Help with Dual Monitors

English Hardware
#1

Having problems running an extended display on Suse 11.1

Primary monitor is an Asus Z53F, 1280x800
Second is a 32" Samsung TV (DVI) 1280x768

At the moment it only works when they are both running 1024x768.

Compiz/emerald is running fine.

Had problems with this same laptop on Ubuntu 9.04, same issue.

Here is my current Xorg.conf

Any help much appreciated.

It seems your virtual screen size is set to 2048 x 1200. To accommodate two 1280 x 800 screens it should be 2560 x (>=800), or 1280 x 1600 if you want to stack them.

I remember reading about some limitations in virtual screen size, possibly depending on the Xorg version you’re running, you may want to research this first.
