I just got a MBPr. When the display switches off, like its going to sleep and I quickly hit a key to wake it back up. It shows a black screen with a cursor for about 15-20 seconds before the login screen appears. Its only if I do it instantly after the screen switches off. If I leave it off for sometime it comes back instantly...
Its not a problem when I don't log back in and let the screen go black from the login prompt.
I also tried to totally disable the show login screen after screensaver/sleep option and it still take a while to go from black to my desktop.
This is a problem if I have an external display plugged in or no displays attached. Its really annoying because I want to stop it from sleeping because I'm reading or something.
Is this normal? How can I troubleshoot?
