Dual monitor with dual graphics cards problems

Apr 01, 2008, 08:19 AM

*sigh* Problems with trying to get a dual monitor setup working right.

Hardware is as follows

NVidia GeForce 6800 driving Sony CPD-100ES monitor, capable of 1400x1050 but I prefer running 1280x1024.

Old Matrox PCI card driving LiteOn B1996NST monitor, capable of quite a resolution, but it has focussing issues. I want to run this at about 800x600, and use it primarily for the TV card. This means it has to support video overlay.

Currently I have the dual monitors working, but with a few problems:

1) The primary monitor has the desktop resolution larger than the screen resolution (causing the desktop to 'scroll' when I move the mouse to the edges).

2) Video overlay on the secondary monitor is working, but not scaling. (Same for the primary monitor)

3) Currently using the nv drivers, I'd like to use the nvidia ones if possible, for 3d acceleration.

EDIT: Ahem, my xorg.conf

Code:
