** Summary changed:

- Cannot shutdown or restart from user session with nvidia drivers via 
nvidia-prime installed
+ Cannot shutdown or restart from user session with nvidia drivers in an xorg 
session

** Description changed:

  Fresh install of 09/07 image on Lenovo y510p laptop GK107M [GeForce GT 755M]
  nvidia-375 drivers installed, tested.
  Then fully updated
  Absolutely nothing else done..
  
  Note: this occurred both before & after the gdm3 update.
  
  What happens:
  Attempting to restart from either the gui or in terminal leads to a black 
screen with blinking cursor. Waiting does nothing.
  Going to tty1 shows wall of text, cursor just blinks there also.
  
  However if I go to tty7 then the shutdown immediately proceeds &
  finishes.
  
  What also works is instead of attempting shutdown  normally going to
  tty2 & issuing command there.
  
+ This is also reported to happen to Desktop nvidia gpu users whose
+ hardware is better with nvidia drivers 3.40 or earlier, i.e. they can't
+ use wayland either.
+ 
  As A side note this does not occur with lightdm
