[SOLVED] nvidia dual screens

[SuperSonic4]

I am running Mandriva One 2009.0 using KDE4. As such the nvidia driver is 177.80 (I'll check on my Mandriva partition tomorrow).

The problem is that whenever I try to use a dual screen it ends up being a black background with a cross for the mouse icon whenever I hover over it.

This is more of an inconvenience than a reason to change distro but it would be nice to have both screens.

I'll post my xorg.conf when I get back to my linux box

It is 177.80 and below me is xorg.conf

I'm not sure (I haven't used a dual NVIDIA setup for ages), but - how did you install 177.80? From /backports , or from upstream?

[SuperSonic4]

I found it in the repositories so it would have been from /backports (I did enable it)

[AdamWill]

Ah. I'm not really sure, in that case . Sorry. One thing you can try is to read the NVIDIA driver docs - which are really good - and then set up xorg.conf by hand. That's how I used to do it when I had a dual-screen NVIDIA setup (although that was mainly because nvidia-settings didn't exist at that time).

[bartos]

You should be able to run nvidia-settings as root. Set the screens how you like and then click Apply and Save to Xorg File

This is how I setup dual screen on my Dell desktop when I ran Mandriva2009 on it (gnome). I didn't have to manually install anything; Mandriva installed the needed drivers during install. Once I booted into the system I ran nvidia-settings (as root) and enabled my secondary monitor.

[SuperSonic4]

I tried that but it either gave me a blank screen with a black X on or the resolutions don't match. Full screen video isn't working which is a pre-requisite =/

[bartos]

I forgot to ask if you went to System -Preferences -Screen Resolutiions and put a check mark in Mirror Screens. Do this first and then setup twinview in nvidia-settings as root.

[SuperSonic4]

Cheers but I don't want Twinview since they're two different monitors. Separate X screens is a must
