I have a user who wants to have 4 monitors attached to his CentOS 6.4 system. I know that you can't use both on-board video and a PCI video card at the same time, but what about two PCI video cards? The system seems to recognize them as shown by the lspci -v output below, but I can't get Xorg to use the second card. Has anyone done this? If so, what is the trick to get it to work?
What does xrandr report?
(I've used Matrox M9140 and the matrox prop driver. That combo provides quad monitors with one graphics card.)
