What command line or which graphical tool did you use to install the 
nvidia driver? Something seems to resolve the dependencies and 
recommendations differently than in my tests (where I don't see that 
library installed).

I'll try to make the mere presence of libnvidia-cfg1 but no other driver 
components to no longer enable the "current" nvidia alternative (which 
has higher priority than the legacy one).

If you need to make modifications, place them in /etc/X11/xorg.conf.d/ 
otherwise they get overwritten on upgrades.
