[MacBook Air] Blank screen on wake up

Just installed 12.1 KDE on my MacBook Air 3,2.
Most things work rather beautifully out of the box. Only real worry is that when I close the lid the computer goes to sleep, but when I open it up again, although the back-light comes on, all I get is a blank screen.
Does anyone have any idea what I could do/check/report back?
Thanks in advance.

No idea, sorry. I have no problems using opensuse 11.2 - 12.1 on diferent
macbooks, though not an air amongth them.
But I guess you have an nvidia graphics board in it.
Back screen after wakeup is a well known thing if you use the proprietary
driver. Have a try to follow htat path.
Good luck !
