ok, maybe somebody can help me to configure the 2 video devices in XF86Config. To be able to use two video devices XFree needs to know the BusID of each one.
I've ran ./scanpci and I got this this info about my video devices:
In XF86Config I need to specify the BusID in this format:
# BusID "PCI:0:10:0"
How do I figure out this numbers from the info I get from scanpci?
Thanks!

I took a look at man XF86Config-4 and found that BusID is in the format "PCI:bus:device:function" (so "PCI:0:12:0" and "PCI:1:0:0" for your scanpci output, respectively).
I''ve never setup multiple monitors on one machine (simply because I don''t have enough money for even one good monitor, must less two
), so I can''t give any specific advice. Multiple monitors is fairly routine in the X world though (just throw two monitors, devices, and screens in XF86Config-4, as you''ve probably guessed), so it shouldn''t be too hard and your desktop environment will probably handle it nicely. Good luck

Oh, thank you so much for replying
Ok, I''ve this so far, maybe you can point me out what I''m doing wrong. The two monitors works very well in MSWindows. This is the XF86Config file I wrote so far:

that all seems ok, apart from the server layout section. you just need one like this:
or you can change leftof to rightof to depending on which way round the monitors are.
edit: also, depending on your window manager, you may have to use xinerama, which will treat both of your screens as just one big screen rather than separately. to enable it you'll need to add:

Thank you necromancer, I did what you suggested but it still doesn''t work. There is so little info about this on the web, and I''m so tired... damn. I wish I had more time to do what I like!

i see what problem is, the card number from scanpci is in hexadecimal (the whole 0x.... gives it away), and XF86COnfig wants it in decimal. so you need to change it BusID "PCI:0:18:0" for the permedia card.

Holy **** what ever happened to plug+play?
In Windows you just plug the card in, turn on the comp, install the drivers, reboot, open display properties and you're done. (unless your PCI card is non P&P in which case you also have to switch one option in the BIOS).
Now wasn't that simple?
