I am currently using a nvidia pcie card to control 2 of my displays. I'm using the nvidia "TwinView" option.
This all works fine and dandy, but now my problem is that I want to add another display connected to the onboard ati radeon video.
I used nvidia-xconfig to set up the nvidia stuff, but now I'm having a hard time setting up /etc/X11/xorg.conf to enable the 3rd monitor.
Here is my current xorg.conf
Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 280.13 (buildd@allspice) Thu Aug 11 20:54:45 UTC 2011
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 280.13 (buildmeister@swio-display-x86-rhel47-03.nvidia.com) Wed Jul 27 17:15:58 PDT 2011
