True. I remember editing sources to do so in the "distant" past (simple stuff, 
however).

The only reason I am using the nvidia-legacy is problems in KDE, Iceweasel 
hangups and segfaults. Responders to these bugs said forget Nouveau, which BTW 
I do like, and go to the proprietary NVidia. May or may not still be the case.

At one time, I had boot command lines to choose Nvidia vs Nouveau, but things 
have changed, i.e. systemd, no more Xorg.conf, etc. If someone could tell me 
how to accomplish this now, I would be a happy camper. Apparently, a blacklist 
file is all that controls whether or not the included Nouveau driver is 
activated. Simply a missing nvidia driver dkms update will produce an error.
