You have been subscribed to a public bug: I'm running Ubuntu 16.04.2 on an unibody iMac from 2009. However, even with the most recent HWE stack (kernel 4.8), the display stays black after suspend. I can ssh into the machine, so wakeup is OK, but the display doesn't do anything anymore. Blindly switching to the console and back also does not help.
I will update this report with information from https://wiki.ubuntu.com/Kernel/Debugging/Backlight once I get around to it.
