What causes a black screen after sleeping in Mountain Lion?

Question

macOS

Very strange crap, I open the lid of Air 2011 after the update, the cursor appears on a black background, although in fact it shows a password entry screen, because. when you enter the password and press Enter, the black screen disappears and the desktop appears. Moreover, after the desktop appears, it can take 5-40 seconds! go to sleep instantly, everything goes out, I press the button and the usual login screen appears, after entering the password in which everything works fine.
Can someone on previous versions of the OS come across?

Answer 1

Disable OpenGL screensaver. If you shamanized with the video driver, go back to the version that comes with the operating system. X-sy does not start to the end, the process hangs, then it is killed by a timeout and the next one starts to be processed - the transition to sleep.
There is also a useful utility - OnyX will remove old caches, sometimes it helps a lot.

Answer 2

As practice shows, until the first update is released, it is not recommended to install a new axis. Each axis is the same.
Try to reset PRAM , it helped me with various glitches. Clean your caches, wait for the first update, set combos and see the results.

Answer 3

I have such a beard occasionally on 10.6.8 on MBP2010.
