Re: Matrox G550 PCI DualView and xorg.conf

Here I report my xorg.conf
It's a bit complicated because I need to have 4 monitors enabled and
I've 2 video cards.

If I enable
Screen 0
Screen 1
in corrispective Device sections for Matrox card
I have Matrox output freezing!

At this moment I have Screen2 and Screen3 (Matrox) with the same view!
:(

I'm using Matrox G550 PCI version with dual view support.
My kernel is 2.6.18-1.2798 from Fedora Core 6.

lspci show me only one BusID:
PCI:2:0:0 VGA compatible controller: Matrox Graphics....
I can't see two BusID from lspci and if I enable

It's the same BusID for the both heads, you still only using one PCI slot.
Do set BusID in both device-sections.

For supported options, take a look at
http://xorg.freedesktop.org/releases/X11R7.0/doc/html/mga.4.html

I do suggest you make a search on the net on dualhead matrox to find examples
of a proper xorg.conf.
