Public bug reported:
When I engage light-locker to lock my screen, it locks the screen and
disables power to the monitor, as it should. However, I can never get
video back again after that. Power to the monitor is never restored,
and the only way I can get my video back at that point is to restart my
display manager, for instance by SSHing in from another machine. At
that point, the video comes back and I can use the system again.
This problem only happens on my AMDGPU-based Radeon system. I have
another system that uses Intel video that doesn't have this problem. I
should note, though, that in Trusty 14.04 the power save and restore
functions worked perfectly fine, and there was no issue restoring video
when I wanted the system to wake up the video. But of course, at that
point I was using FGLRX as my video driver, which is no longer supported
or available in 16.04.
I'm very willing to help debug this, so if there is anything I can do to
help, please let me know.
Thanks,
Brian
