multiple videocards.. need help.
using centos 4.3
just got myself a:
Matrox Graphics, Inc. Millenium P650/P750
and a:
Matrox Graphics, Inc. Millenium P650 PCIe
lspci sez:
01:00.0 VGA compatible controller: Matrox Graphics, Inc. Millenium P650 PCIe (rev 01)
06:00.0 VGA compatible controller: Matrox Graphics, Inc. Millenium P650/P750 (rev 02)
edited xorg.conf to contain the following lines:
Section "Device"
Identifier "Videocard1"
Driver "mtx"
BuSID "PCI:6:0:0"
VendorName "Videocard vendor"
BoardName "P650/P750"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "mtx"
BuSID "PCI:1:0:0"
VendorName "Videocard vendor"
BoardName "P650 PCIe"
EndSection
restarted X and the xorg.log file now contains the following:
(WW) MTX: No matching Device section for instance (BusID PCI:6:0:0) found
further up in the log file the 2 following lines can be found:
(--) PCI:*(1:0:0) Matrox Graphics, Inc. unknown chipset (0x2538) rev 1, Mem @ 0xe0000000/27, 0xe9000000/13
(--) PCI: (6:0:0) Matrox Graphics, Inc. unknown chipset (0x2537) rev 2, Mem @ 0xf4000000/26, 0xe8a00000/13
conclusion. both cards are found, but i am only able to
install driver for the card on bus id 1:0:0
and not the one on 6:0:0
im sittin here scratchin my head and cant quite figure out what i have missed. any and all help appriciated.
kenneth
ps: afaik both cards use the same drivers even though they
have their own links on matroxes drivers download pages.
(unpacking them yields the same file and file structure)

Have you tried removing the BusID line? Sometimes that helps.

This isn't a bad thing really. Even after properly installing the nVidia drivers you'll probably get the same message for an nVidia card.

Does your computer still boot and run X? Is there any reason why your running two graphics cards at the same time? From what I've read on the warning message, X knows your card is there, it just dosen't know what to do with it. Just what exactly do you expect and/or want X to do with it?

oh yeah. it boots fine and X starts just fine. At the moment im
only using 1 monitor so it really isnt a problem now. But i am
to hook up 4 monitors to my machine eventually, and by that time i need to have the second card working.
on my old machine im also using 2 cards and 3 monitors so this
isnt excactly new to me... but im somewhat baffled as to why
im not able to load drivers for the card on the 6:0:0 bus.
regards
kenneth
