I can't seem to get the screen tu turn back on by pressing any keys.
I'm not sure if this is related to https://bugs.freedesktop.org/show_bug.cgi?id=33968 because I'm using the amdgpu driver.

The monitor (samsung U28E590D) is connected by displayport to a radeon r9 fury.

I have done more tests this morning and it seems like I can get out of "xset dpms force {standby,suspend,off}".

Originally when I first had the problem, I disabled screen blanking with "xset s off". My screen went black and I was blocked again so I supposed this time it was dpms.

This morning I confirmed the screen doesn't come back after I have manually turned off and on the monitor.

Unless it works with the modesetting driver, it's probably a kernel driver issue.
Comment 4 jody.frankowski 2016-01-12 07:15:55 UTC 
I thought it might be, because I also noticed that if I boot with the monitor turned off, and then turn it on, the screen will never turn on.
Comment 5 jody.frankowski 2016-02-08 07:18:43 UTC 
As of 4.4.1 I can turn on and off the monitor properly.
I'll test blanking and dpms now.
Comment 6 jody.frankowski 2016-02-10 16:32:02 UTC 
It seems like I can get out of dpms/blanking now. I'll now try to test them separately.
Comment 7 jody.frankowski 2016-02-14 21:27:54 UTC 
I just had a situation where again I couldn't wake the screen. I'll continue my investigation.
Comment 8 jody.frankowski 2016-07-19 18:14:34 UTC 
Hi,

I'm happy to say that I haven't had any issues with dpms/screen blanking as of the last kernels.

Thank you.
