dual display - slack 10.1.0
I was wondering if it is possible to have multiple display support through X, when using 2 different video cards (one matrox, one ATI). I know that it is possible with one dual-head card, but i am not willing (currently) to go spend the money on one...can someone point me in the right direction? All the info i have found so far relates to a dual-head card

camh - Have you tried it with the 2 cards? I think it will work.

How I'de do it:
cd /usr/X11/
cp xorg.conf xorg.conf.original
(make backup of xorg.conf)

Then edit xorg.conf accordingly If it crashes going into X (startx):
cp xorg.conf.original xorg.conf
Then you can go back into X and research if you have too and edit your xorg.conf from there.
Then try again.

The section for the graphic devices should look like this (about):

Section "Device"
Identifier "myvideo1"
Driver "mga"
#VideoRam 16384
# Option "mga_sdram"
# Option "MGASDRAM"
BusID "PCI:1.0.0"
# Insert Clocks lines here if appropriate
Screen 0

Section "Device"
Identifier "myvideo2"
Driver "ati"
BusID "PCI:0.X.X"
# Insert Clocks lines here if appropriate
Screen 1
Make sure you lspci to get the right "BusID" for each card. Then just make the
necessary changes for the monitors, screens, layout, etc. But I'm thinking using
the 2 cards should work. good luck!

awesome thanks for your help. i haven't had a chance to try it yet, as my computer is currently packed away (i'm moving) but i will give that a shot as soon as i'm back up and running.

and how about dual display with an ATI Radeon 9200?
It has 2 outputs: serial and S-Video/Composite, in Windows XP it is very easily to set up for dual display having Monitor1 showing different from Monitor2 if wanted, how easily is this achieved in Mandrake 9.1/10.1??

i only used mandrake 10.1 for a day or 2 and the dual head support that was built in for the radeon cards seemed a bit iffy. after downloading and installing the drivers from the ati website (and reading the instructions for install very carefully) then running fglrxconfig i got much better results. getting it running on my current slack distro was a bit easier but in general the ati drivers for linux are below standard compared with the windows counterparts
