            Bug ID: 102684
           Summary: Monitor sometimes cuts to black after idling overnight
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: bugs.freedesktop@haasn.xyz

This is a rather difficult issue to reproduce. After leaving my PC idle
overnight (monitor turned off) and waking up the next day, I noticed an odd
issue started happening: The monitor started randomly cutting to black for a
second. It was not entirely unpredictable: it seemed to happen especially when
I triggered a seek in `mpv` -perhaps because this either recreated the
framebuffer or recreated some video textures, I'm not entirely sure. Restarting
X seems to have fixed it. The GPU was in power mode 'auto' overnight.

It sort of reminds me of similar issues I had with the nvidia drivers some
years ago, where leaving them in 'adaptive' performance mode overnight caused
them to fail switching frequencies the next day. Leaving them in 'performance'
mode overnight solved that issue; but it has also been since fixed. But that
was an issue actually related to the performance scaling, whereas this seems
more like an issue with the display connection in general.

I'm not sure where else to take this - I can try reproducing it the next time I
go to sleep, I guess, just to see if it will happen again. Apart from that, I'm
pretty much blind debuggin here.

Xorg version is 1.19.3, mesa version is 17.2, kernel version is 4.12.4, device
is a Sapphire RX 560.
