Unusual X behavior - adding another video card (w/Xinerama)

[aBryce]

I have had a working Xorg installation with dual heads on a single (Matrox) AGP card. All is well with them.
I recently aquired a third LCD monitor and decided to add it. I have a free PCI slot, so I added another video card there. It's a Savage IX, nothing fancy at all but it has 8 MB of VRAM and thus should be able to support 1280x1024 resolution with 24 bit color.

Anyway, I put the new card in my xorg.conf:

I tried making the PCI card the primary one in the bios. This seemed like it would work, at first, but it doesn't... the system starts and runs but the monitor attached to the pci card (previously showing the linux console) doesn't show anything, one of my (identical!) lcd monitors also goes blank and says "out of range" and the other shows jumbled garbage (that looks like some kind of video card misbehavior, e.g. flickering and random data.)


If it helps, the last line in the X log is "(II) Truncating PCI BIOS Length to 53248"


Also, the computer, while apparently hung, is not in fact crashed after the above (both posts) described malfunctions. It will still accept ssh logins, shut down gracefully, etc. Killing X does not fix it however, and it apparently needs to be restarted before the (USB) mouse and keyboard, as well as console, come out of limbo.

Is it likely this is a hardware conflict/problem?
