Thanks for the bug report.  We have reviewed the information you have provided

Xorg.0.log

Here's the log from starting X without xorg.conf - btw, is that ok that the "nv"
driver is selected? (I thought that "nouveau" is preferred ...)

No, nouveau is not considered stable enough.

Same problem here:

No xorg.conf, but X autodetects the display just fine:

I've got the same problem but I'm using the nvidia proprietary driver from rpm fusion repository. I'm running fedora 10. Here's the output:

amrlima@Gert:~$ system-config-display

This is by the way my first bug comment in Fedora.

Fixed in rhpxl 1.10, coming soon to a rawhide near you.
