Dual-Screen View in ubuntu?

[Davestom]

Hey Everyone, using the following guide, I got both screens to work;
LINK: http://www.ubuntugeek.com/dual-monitors-with-nvidia.html

but my problem is that both screens show the same, and I would like to have 1 screen showing Desktop1 and other Desktop2. How can I do that? (I guess its something with xconf to do ?)

System->Preferences->Screen Resolution? uncheck mirror monitors.
You can have the two monitors showing different things, but when you select your second desktop, both monitors will still switch to a fresh view.

There probably is a way to do what you're saying, and have other desktops displayed on your second monitor, but I don't see why you'd want to do that as opposed to having a single desktop displayed that's two monitors wide, because that way you can a) still have multiple work spaces using desktop switching b) drag windows between monitors without relying on a compiz fusion plugin.

The mirror image is unchecked :-S And if I check it, it says ERROR. - but it detects both screens.. kinda wierd.. Im totally confused.. but found this guide:

Okay.. I got it installed but without all that crap they are writing about,

You can go in nvidia x server and choose what you want (in my case: TwinView), then you can aply (by clicking the (disabled) screen) - but this only works once..
=> So if you want to keep these seetings you have to find the script in Xserver (I can post where when Im on ubuntu) and then replace it with your xconf. -file, but remember to backup your old :)
