Black screen after wake

[Roberto Burgos]

I got this issue once a day or so when I close the lid of my laptop to suspend, and when I try to wake it up I get a blank screen where often the only thing that shows up is the mouse cursor. I can't use the mouse nor keyboard, and I can't access virtual consoles (ctrl+alt+f1). I'm forced to shutdown the machine by pressing and holding the machine's power button.

Hi,

I actually started testing the latest v4.6 for another issue I was having with screen flickers after trying to test 4.5.2. So far it seems to be working, but I will have to continue testing since this issue happens daily but at random times.

Roberto Burgos, to clarify your comment https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1577284/comments/4 which kernel specifically did you test?
