Description daleville 2006-03-24 10:19:00 EST
I am unable to use my nVidia RIVA TNT2 Model 64 PCI card in combination with any
other video card that I have tried with X. Whenever attempting to load X with
the aforementioned card alongside any other card results in the display becoming
locked, forcing a reboot. I have tried this card on two systems running FC5 with
the same results. One system I tried the combination of the onboard video and
the PCI nVidia card to no avail (dual head with this exact same setup worked in
FC4). Then I tried the same system with an AGP nVidia card along side the PCI
nVidia card with the same results. 

The machine I currently am using and having the problems with I will detail below.

/sbin/lspci -v

Xorg -scanpci

(1:0:0) nVidia Corporation NV11 [GeForce2 MX/MX 400]
(2:9:0) unknown card (0x10de/0x0006) using a nVidia Corporation NV5M64 [RIVA
TNT2 Model 64/Model 64 Pro]

I have attached the resulting Xorg.0.log.

Finally the PCI nVidia card will successfully run X when it is the only card in
the system.
