Matrox G550 PCI DualView and xorg.conf

FabX · External Since: Dec 28, 2006 Posts: 29

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
Screen 0
Screen 1
in Device section I can see only freezing screens!

Have you any suggestion??
THANKS!

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!

FabX,

Please clarify: is the i810 a *built-in* onboard grafix card? Or is it
in a PCI slot of its own? IIRC, one may have to disable the onboard
video to allow a PCI card (the Matrox, Neo) to do the video work. For
you to get a max of 4 monitors running, if what I said is true, then
you need to have another dualhead-capable card in another PCI slot.

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.

When looking at your xorg.conf, it looks like you are trying to get 6 monitors
out, I'm not sure the driver really supports that many outputs per card, which
may cause your trouble.

Change that one to:
Option "MonitorLayout" "CRT"

i810 is a built-in video card with 2 output: VGA and TV-OUT.
I like to enable both of them (fully working) and both output
of Matrox G550.
At this moment I have VGA and TV-OUT of i810 working.
I have also VGA of Matrox working but showing the same screen...
so in total 3 monitors. I like to have 2 separated VGA of Matrox.

I just tried that but built in video card "i810" is working good. Also
MonitorLayout specify what you want to enable of your video card so
I specified both "CRT and TV". Display option specific what Device
section is for... so in one case it's for "TV" and in the other one is
for
"CRT".
This is what I understood reading xorg.conf.

So,
the problem remain in Matrox card which shows the same screen
on both the outputs.

I tried to use many options like what you suggest.
But all this cases require to specify
Screen 0
or
Screen 1
for each device section.
The problem is that if I try to include
Screen 0 or Screen 1
in my xorg.conf, I can only view freezing screens for matrox.
However playing attention looking at the freezing screens they are
in clone mode the same.

Did you ever do what I suggested or you just ignoring advice?

In those drivers which supports MonitorLayout, you generally have the following:

If you use 'MonitorLayout "monitor1,monitor2"', then only one device-section

if you use 'MonitorLayout "monitor1"', then you need two device-sections, one
for each monitor.

In your case I think xorg is kind enough to ignore the second device-section
for your i810 and this could of course cause troubles for your matrox.

MonitoryLayout is supported only if you have 830M chipset or later.

Looking again at the mga driver supported options,
http://xorg.freedesktop.org/releases/X11R7.0/doc/html/mga.4.html
you find it don't support MonitorLayout, the same for all the other optional
drivers you could choose to use.

Looking at the example configuration that matrox has in it's driver readme
(not sure if this is the same driver that comes with Xorg),
ftp://ftp.matrox.com/pub/mga/archive/linux/2006/readme-mga-4.4.0.txt

It don't say if it can create separate views or if it's just clones, if the
second head on your card is a tv-out, then in the device section try with

Option "Tv" "yes"

Did you specify Xinerama as 'true' (step 9 in this thread
http://www.ubuntuforums.org/showthread.php?p=1773624)? Follow this
thread but I still think x has to know which is Screen 0 for the
monitors connected to Matrox. And I found the Gentoo wiki which has
separate sections for different brands of graphics cards Smile
