Red Hat Bugzilla – Bug 74625
fails completely on system with two video cards

I have a box which has two video cards, an on-board 810 and a PCI nVidia RIVA TNT2:

I'm only using the nVidia card.
redhat-config-xfree86 fails totally in generating a config for this system. I
could only get an X setup by running XFree86 -configure, copying the output to
/etc/X11/XF86Config, and using that as a starting point for redhat-config-xfree86
Also related to bug 58532.
Is the i810 card disabled in the bios?
The BIOS doesn't support enabling or disabling on-board video (it's a rather
sucky Phoenix BIOS)
Systems whose bioses don't allow you to properly disable the onboard video seems
to be an increasingly common problem.
Can you test with redhat-config-xfree-0.7.0-4 in Rawhide? There have been lots
of changes to the code. I believe that the rhpl libraries now handle multiple
On my wife's Dell, which has an on-board i845 graphics card (with no monitor)
and a PCI Radeon 7500 (which has the monitor attached to it), the program no
longer crashes but it identifies the on-board card instead of the Radeon.
I suspect that this is because kudzu scans the system in PCI bus order and it is
finding the on-board card first, so that's what is getting returned. I'm
willing to bet that on your machine, the GUI will show the i810 card and not the
At least the program doesn't crash anymore. I think that once the GUI is up,
you should be able to go to the Advanced tab and click "Configure" in the
videocard section. This should allow you to select the nVidia card in the video
Detecting which card is correct is a much more difficult problem. We may not
get that level of detection done with the next release.
