I haven't run nVidia druvers from elrepo, and I believe that 340 is now 
beyond EoL from nVidia itself;  but ISTR that when attempting to switch 
between nouveau and nVidia-based drivers the most recently installed one 
will often work.  If your system is currently unusable this might be 
worth a try.
