I have a working 2D KDE desktop under Fedora 22 (clean install) with the
nouveau drivers, but 3D things such as steam do not work.
I uninstalled the nouveau driver and installed the nVidia drivers with
dnf remove xorg-x11-drv-nouveau
dnf install xorg-x11-drv-nvidia
dnf install kmod-nvidia
dnf upgrade
On rebooting I get a black screen where the login (sddm) should be, and
have to switch to a text mode console on Ctrl-Alt-F2 et. al. to get any
further.
The Xorg log contained the following error messages:

So, why is Xorg still trying to load the nouveau driver? What
configuration step have I missed to tell it otherwise?
Any help would be greatly appreciated.
Many thanks,
