I am using Suse 10.1 and have a dual monitor setup which I had setup so that each monitor is it's own desktop. I don't remember what the option is called, but it's not the one where you get two cursors and your actions on one screen is duplicated on the other. So basically I could drag stuff from one monitor to the other.
So last night I installed Xgl on my machine and I'm having a problem where if I maximize a window in one monitor, it will stretch across to the second monitor. I went in the gnome settings for the video and It was on the same option as before. The only other option is the clone one which duplicates what you do on one monitor in the other which seems kind of pointless if you ask me.
So I was wondering if this is an XGL thing or is there something that's not setup correctly? I followed the instructions for setting up XGL from the novell website(http://www.novell.com/coolsolutions/feature/17174.html)

Sorry if I am misunderstanding your question.
What I believe your describing with the window stretching across both screens is the default behaviour of xinerama(dual screens) and XGL. There is no way as of yet as far as I know to have a seperate cube on each desktop. I did notice that there have been several requests for that type of set up. I run kde for instance and most of the window manager options for kde are of no use like where and how you would like windows to appear. This is annoying because very often the window seems to appear right in the middle which is of course where the screens come together. Compiz is the new window manager I guess and I have not run across a way to control where windows appear of how they appear yet. So I think to sum things up you cannot have seperate desktops on each monitor yet because that is not how the setup was originally envisioned I guess,its a cubical desktop in 3d space and it would be impossible to visualize two sides so that both form an ideal square but I am not a metaphysics major
I just downloaded the latest cvs of xgl and on reboot I got twin screens each its own screen."xinerama" "off" was listed in my xorg.conf. I dont know for sure if it was the latest update of xgl that fixed this but I think so. Anyways I am quickly learning there are advantages to both set ups.Windows no longer cover 2 screens unless you unmaximize and spread across the whole screen which is nice but my kiba dock is trapped in the wrong screen

Good to know. I have Xgl disabled because maximizing a window stretched it across both screen which was useless for me and really annoying for web browsing. But now, I might have to see about running an update and give Xgl another try. Thanks for the tip.
-edit-
A bit off topic but I have a quick question....I have my dual monitors setup as [2][1] so screen 2 on the left and screen 1 on the right. But I always wondered why Linux always picks up my screen on the left as screen [2] and my screen on the right as screen [1] but windows picks up my screen on the left as [1] and my screen on the right as [2] so I don't have to tell it to switch the screens around. I'm pretty sure my screen on the left is on card[0] of my nvidia 7800GT card...any suggestions?
