With Ubuntu guest I also get an error, it says "glx" not found and I cannot successfully login in the guest OS, I just get a blank screen with the Ubuntu logo, although with the Nouveau driver I have no problem and the VM OS actually can see the GTX Graphics card. The problems only begin after installing the NVIDIA drivers. So this is a troubleshooting attempt.

It's pretty well guaranteed that a 500 series GeForce does not support
UEFI.  AFAIK, there's not a terribly high success rate with these cards
either.  The 600 series are generally what I consider the bottom end of
working reasonably well.  Otherwise there's not really enough
information in your report to provide any specific advice.  Thanks,
