Dual Monitors

[guod]

I am fairly new to linux. I am trying to get my dual monitors working on a Dell Demension 8300 with 2 video cards. A Nvidia GeForce FX 5200 and a Nvidia GeForce 2 MX 400. The monitors are both Dell E173FP. I can get either screen to work by itself by changing the xorg.conf file but both monitors will not work together. One is always black. I am using the System Settings --> Display to setup the dual head. I have installed the 'nvidia' drivers from their site. What ever card I have listed as Videoard0 is the one that works. Does anyone have any clues how to get these monitors to work together. The current config works on wxp. I will attach my xorg.conf, Xorg.0.log, and lspci-l. I have also run the 'Nvidia-xconfig' util from Nvidia but that did not change anything.

It appears that the card that is 'Videocard1' in the xorg.conf is disabled. When i run the lspci -v, the bus that is not working has [disabled] next to the memory adresss. Can the setpci command reenable the pci memory?

The monitor itself says it is in power save mode.

Thanks for your help community

your xorg.conf looks great however looking at the logfile it leads me to the conclusion that the busID is incorrect.


"NVIDIA: No matching Device section for instance (BusID PCI:1:0:0) found"

FYI: you dont need to list the busid of videocard 0 only the 2nd or 3rd etc.. cards

im not 100% but try setting it to 0:1:0 instead of 1:0:0

everything else looks correct to me, hope this helps!

It looks like the pci bus 1:0:0 is the right one. It is the bus listed in the lspci -v and also, if I take the BusID and driver and make it Videocard0, when I startx X, that monitor will come on and the other will turn off when it is listed as Videocard1. I am wondering if it is a probelm of the Demension8300 motherboard and linux. I have tried 2 other video cards and have the sam issue. I have tried it with RHEL4 and FC5 and both have the same issue even after reformatting. I was just wondering if I could run some setpci command to get thae disabled bus to work, thanks for your help
