Twinview Problem

[da_seeb]

Hi

I've got a strange Twinview problem. While there is shown the login screen, my second monitor is showing a picture. After login, when kde starts loading the second monitor turns off.


Any help? very strange, because X seems to be configured correctly, looks like a KDE problem

Here is my xorg.conf:

Re: Twinview Problem

I got Twinview working with Xinerama but this doesn't seem to be a perfect solution. Scrolling is slow and not smooth, transparent menus appear slowly...

Is there a possibility to enable 3d/2d acceleration?

What exactly is the difference between using Nvidia Twinview and Xinerama?
