Hello. I've recently been trying to get the Xinerama extensions with
XFree86 4.1.0 (stock from Redhat 7.2 install, no updates) working. My
computer is a P2 233, with two video cards:
Onboard Matrox 1064SG, on the PCI bus
Matrox 2064W PCI card in PCI slot
If I use just the 1064SG onboard card, it works flawlessly. If I place
the 2064W card in, it works flawlessly as well. So, I tried to setup
the Xinerama extensions. It appears that I have the configuration file
setup properly, but here is a copy of it (The 1064 card is labeled as
Onboard, the 2064 is labeled as PCI)

When I try to run this, it just hangs. I have the hanging XFree86 log
file attached to this email. Since both cards use the mga driver, I
tried comparing the working 2064W log with the Xinerama log and saw this
problem:

That is really the only problem that I can tell. I've also tried just
running the onboard video card by itself, and it also refuses to run.
It appears to stop in the same place. I was afraid that the onboard
video card might be broken in some way, but I have both cards working
flawlessly in Windows 98 SE. If anyone can shed any light on this, I
would be very very appreciative :)
Thanks in advance,
Josh Hogan
