Hi everyone.

I can be able to setup the xorg server trough a conf file saved in /etc/X11/xorg.conf.d directory. With this I get the desktop in the Screen 0 and in the Screen 1 I only can move the mouse, but I don't see any wallpaper and can't move any window there.

I have tried to use Xinerama, the problem with this is that I need to configure the same color depth for the two monitors, but when I try to configure it with DefaultDepth 16, the view at Screen 1 is awfull, it only displays the middle of the screen. And with DefaultDepth 24 the xorg server crashes.

Could you help me please?

I am using Fedora 17 with LXDE desktop.

Here is the conf file that I am using:
