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, -- Seb
