Hi,
I have been customizing my own Knoppix CD, but in one thing I am failing: I want to have all my graphic adapters recognized and put together as Xinerama screens one "RightOf" the other.
I began with the problem to find the PCI addresses of the vga cards, and I found the following:
Code:
lspci -m|grep VGA|cut -b 1-7|sed -e s/\\./:/
But I don't really understand how Knoppix gets its XF86Config-4 file, where the information comes from and stuff. Could you explain to me how the X configuration system works and how I can change it to support multiple screen environments if more than one graphic card is installed?

Thanks in advance, Mathis

EDIT:
Just to clarify, I am trying to make a bootable Knoppix CD which can automatically discover one, two, three... graphic cards and configure them nicely with KDE to be right of the previous one.
I am aware of existing topics which seem to be about this problem, but it seems to me that some of them have a HD install of knoppix and the others have one graphic card with dual head support.
