Dual monitor on SUSE Linux 10.0, Matrox G550


Hello, I am trying to get dual monitor support working on my Linux system.

My graphics card is supported in Linux, and SUSE installed the newest driver. But I am not able to see my left screen (the 955DF monitor).

I'm using:
Matrox Millenium G550 Dualhead
Samsung 955SL 19" CRT
Samsung 955DF 19" CRT

Any help is appreciated, thanks!

I wiped out my xorg.conf, and recreated it manually, but it still does not turn on. Is there a way to 'activate' it in the config?

Xorg.0.log looks like it could be showing some problems, I can't post it, unfortunately, because it is too long.

Suse comes with yast, configuring tool, or even directer sax2
there you are able to configure monitors, graph. cards etc.
as I remember under Multihead there is a xinerama opion, a single head and another I think?

check those settings,

you can try to make the monitor work by changing resolutions and colors then test after. because fist your monitor must work fine, then both your screens together.

Now since I created a second "Device", I can see two display tabs in sax2. But I cannot activate the second device because when I try to test/save I get an error message: "Data incomplete in file /var/lib/sax/xorg.conf Undefined Screen Screen[0] referenced by ServerLayout "layout[all]"

I believe this is because I manually edited /etc/X11/xorg.conf instead of using sax , so it is messed up.

User error!

User error!

I was actually viewing the wrong console on my KVM.

It works beautifully now, one big desktop @ 2720x1024.

And the best part is, I didn't have to research my monitor information -- I searched Google for '955DF xorg.conf' and found the correct horizsync & vertrefresh

hmmm, all you had to do was add a second device to get the second monitor recognized?
cool. where did you add it in the xorg.conf?

i've got a 5500 fx i'd like to do this with. 2 CRT's though, maybe it'll be different.

If that's a dual head card (video card with two plugs), you want to edit your xorg.conf and see if you have two [Device] sections. If you only have one, just copy it and paste it, and change the identiifer & screen #. Here are my two device entries:

Code:
Section "Device"
  BoardName    "G550"
  BusID        "1:5:0"
  Driver       "mga"
  Identifier   "Device[0]"
  Screen       0
  VendorName   "Matrox"
EndSection

Section "Device"
  BoardName    "G550-L"
  BusID        "1:5:0"
  Driver       "mga"
  Identifier   "Device[1]"
  Screen       1
  VendorName   "Matrox"
EndSection
Then restart X and you can go into your GUI config software to have your monitor & screen set up. If that doesn't work you will need to manually edit your xorg.conf again and add a similar screen and monitor sections, and finally add the screen to the ServerLayout section. eg:

Code:
Section "ServerLayout"
  Identifier   "Layout[all]"
  InputDevice  "Keyboard[0]" "CoreKeyboard"
  InputDevice  "Mouse[1]" "CorePointer"
  Option       "Clone" "off"
  Option       "Xinerama" "on"
  Screen       "Screen[0]"
  Screen       "Screen[1]" LeftOf "Screen[0]"
EndSection
