I installed ubuntu on macbook air using these instructions


Now whenever I put my mac on sleep (closing the lid) while using os x, the screen doesn't turn on on wake up. So I have to force it to shut down by holding power key and turn it on again.

What should I do? Your help is much appreciated.

Thanks, Ruturaj


while using os x ??

There is a bug known to do that in Ubuntu .. you can only set brightness to ether 0 or 100 % after suspend ..

but haven't had any problems with OS X ..

It will be better to ask apple's community or their tech support if you are having problems with OS X

  • thank you for the brightness comment! That fixed it for me. Hitting the brightness up button now shows me video. – Dan Herman Aug 16 '16 at 1:39
