# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"

# If you'd like to switch the positions of your capslock and

Nothing is wrong with the file. However, it may not work with your hardware setup. More info is required.

It took me forever to edit this file so that the system would start and now that It looks liek all is well with the file but the system starts up as if I did nothing to the file, please help. BTW:I have just update my system with all the updates. Isn't Xfree 4 suppose to have a GUI for multi setup? I'm using Gnome.

I googled "XFree 4 multiple monitors" and came across this link:
http://www.unixgods.org/~tilo/linux_Nmonitors.html
It's reptty comprehensive. In fact, he has his XF86Config file posted and explained on the site. The only difference I could see it that he has the Bus ID defined for each video card. Otherwise, it looks like you've got everything else set up fine. Chech out the site, it may be helpful.

Thankz, I've seen the page. I think the problem is that there is no working driver for the video cards that I have (they are both old and shitty) is there anyway that I could get some other drivers that might work with these cards?
I tried removing 2 of my cards and reinstalling linux to see if they would auto detect but they would not. The screen went blank. I'm assuming that linux picks 'the best possible driver' and has no idea weather or not it works.
BTW: I have 3 video ports, 2 video cards and one onboard video port. I think that the Bus ID is for dual head cards.
