I can confirm that after installing nvidia driver 173.14.27, the problem with the black screen after switching to a new user and logging off is gone!
I have had this problem for a long time! I tested it four times in a row. Prior to installing the new driver, I hit the failure each time after switching to a new user and logging out.
