NVIDIA X Server Settings thinks I'm not running NVIDIA driver, but I do.

[Oliver Ruebenacker]

     Hello,

  I installed the nvidia driver via yum from RPMFusion and lsmod confirms
that nvidia is loaded and nouveau is not.

  But when I run the NVIDIA X Server Settings (KDE on F20), it claims I do
not appear to be running the NVIDIA driver and should configure it by
running nvidia-xconfig as root and restarting the X server.

  nvidia-xconfig creates an new /etc/X11/xorg.conf file (see below).
Previously, no /etc/X11/xorg.conf file existed.

  Then, when I try to re-start X, it will not start saying no screens
found, until I remove the xorg.conf file and then everything is back to
normal, including NVIDIA X Server Settings saying that I do not appear to
be running the NVIDIA driver.

  Did some googling and followed some advice to set the BusID in xorg.conf,
but did not help.

  Any ideas? Thanks!

     Best,
     Oliver
