Problem with dual display



Ok so i installed Zenwalk Linux with just enough knowledge to use bash and install packages thinking that there may be a few bumps on the way but i would solve them eventually. I was pretty much right bar one problem:

I have a 13" CRT piece of crap that cost me a whole $2. If my multi monitor setup hadn't worked perfectly on windows then i would blame it on my bullshit second monitor.
It's plugged into my digital port on my GT6600 using a digital to anologue converter, and when i start up Xwindows it looks something like this:
images2.dmusic.com/users/a/z/h/azhazhellfire/50674.jpg
What I ideally want is a 2048x768 desktop spread over two monitors like i have on windows.

I've tried every multi display tutorial google can find but every single one has either miserably failed or has been way way too complicated for me to understand. But having made many mistakes and changes to xorg.conf i'm back at square one with my original xorg.conf.

Please help.

Can we see your xorg.conf file? Are you using twin-view or xinerama?

If it helps, I have an xorg.conf file available on my server that drives my dual-head setup, but I have identical monitors so you will have to edit it to your circumstances:

Hey. No I don't have two cards, I have a dual-head nVidia card. Same as you no? Is the GT6600 a dual-head nVidia card? Does it support twin-view?

Basically you have two choices. If your card supports twin-view you need to install the binary nVidia video driver. This may be a difficult step in itself, but once that is done it is trivial to set up the two monitors.

Otherwise you need to use xinerama. I can'treally help too much with xinerama, because I have never used it.

So: let me know how you want to do this and we will go from there.

Ok so I got the install, tried to run it but failed. It says my kernel is not supported, then tries to compile a new kernel or something like that but can't find kernel.h. So being an impatient retard i decided to just search for kernel.h and point it in its direction so here's what happened:

sh [installer path] --kernel-source-path /usr/include/linux
/usr/include/linux/include/linux/kernel.h does not exist.

So logically:

sh [installer path] --kernel-source-path /usr
/usr is not a valid kernel path (or something like that)

So probably my best option is to find out the details of my kernel and get the source. how would i do that? and do you have any other suggestions?
