I've been testing around my black screen post sleep-problem. Just to make sure that my hardware is not defective I installed Windows and tested the sleep on it. Sleep works on Windows.
I'm wondering, if the problem could be HD4600. If the problem was backlight screen should stay totally black, but currently screen wakes for a split second (you can see programs and such on the screen after sleep, and then it goes black) and after that screen "glows black". I mean, like there was fullscreen black image on the screen and backlight seeps through. How I could troubleshoot how graphics driver behaves to track this problem down? Graphics is regocnized as "Intel HD Graphics 4600 1536 MB" - maximum memory you can set in BIOS is 512MB, could this inconsistency have any effect?
