Can you run dual screens with Linux?

Hi all,

I just picked up a second monitor for my Linux box and was wondering if there was a way to configure it to run dual. It's running SuSE (10 I think, forget what I ended up with last) and it's got a X800XL vid card with a Samsung 730B on there right now. I want to hook up a Benq FP202W, preferably along with the 730 since I've barely used that one and I already have 2 screens on my main computer.

I'd like to run it spanned across the screens.

Thanks for any help.
 
Yes - I know you can with nVidia. nVidia calls it "Twin View" and it is built into their latest drivers so a drunken monkey can enable this. It was available also on older versions of nVidia but you had to edit the xorg.conf file.

I will never use an ATI chip so I could not help you there...
 
You can do it with out Twin View or xinerama.. if you need too. just configure 2 different screens.

oops.. I didn't see you wanted it to span across screens. I have it setup as 2 separate screens in my conf file.

I am running Ubuntu with dual screens and the desktop spanned accross them both. I would like to seperate them because I can't get any wallpapers to work out right. What do I need to edit to have the screens be seperate? Any down sides to this set up?
 
I'm running a fairly simple setup. I'm not using KDE, or Gnome, so I don't know how it will work with those. I seem to remember not being to drag programs on to the other screen..
It's sort of straight forward. You have to create 2 devices, 2 screens and 2 monitors. I got most of this from gentoo's wiki and Ubuntu's forum I think..

Here's the important parts of my XF86Config

Code: 
Section "ServerLayout"
	Identifier     "XFree86 Configured"
	Screen      0  "Screen0" 0 0
	Screen 	    1  "Screen1" leftOf "Screen0"
