I had this on my 16.04 system and it was INFURIATING - was taking 30s or so to 
login after a lock screen. 
I *think* I've found a workaround...
Changing the driver to neuveu reboot ( deal with the failure to detect 
resolution if needed )
change back to nvidia driver reboot
back to normal :) ( for the last 3 locks at least... fingers crossed!
