Hello,
I've recently moved onto a setup with:
* 3 monitors
Resolutions:
- 1920 x 1080 (2)
- 1680 x 1050 (1)
* 2 videos cards
- GeForce GT 720
- RV730 Pro (Radeon HD 4650)
The two monitors with the same resolution are plugged into the GT 720
and the remaining is plugged into the HD 4650.
After a lot of effort I was able to get the monitor(s) from either card
to function properly with the attached /etc/X11/xorg.conf. The
"Default" layout works well whether I use the Screen section from either
video card. Unfortunately, it fails whenever I attempt to combine the
screens. In the latter case, only the Screen section that is listed
first gets displayed properly, and the other shows a black screen(s)
with an X-shaped cursor whenever the cursor wonders into the area.
Any tips on what is going on? Have others been successful in setting up
a config file for a multiple video card system requiring a mixture of
drivers like nouveau and radeon?
Thanks,
