Having problems with suspend on a Macbook Air 4.2 (Samsung LCD & 256GB SSD).
When I'm closing the lid the apple would stay lit for a sec and then backlight is switches off.
If I open the lid - everything is ok, I'm promted for a password.
But in above situation, if I won't open the lid immediately, after a couple of seconds the logo would lights and dims again. Then when I'm opening the lid afterwards the screen behaves crazy: either I can see the desktop but everything is laggy, have a lot of special effects or I just get a screen of random waves of light like northern lights.
I have been trying to install Ubuntu on this machine for about a week now. And it seems that I'm the only one having this issue.
