Monitor was physically failing, cannot reproduce on other monitors available.

Thanks for the reply Michel, I had tried that earlier to no avail.

Unfortunately I may have wasted everyone's time, the monitor in question
appears to be failing.  It cannot display an image for more than 3 seconds
before going totally black.  

My guess is that the monitor is close to outright dying, so even if I did
experience a bug, I can no longer use the monitor and therefore cannot continue
testing this problem.

I have a similar pb: once my monitor (iiyama g-master) gets into DPMS off mode
from the xserver, _often_ (it does work sometimes) the monitor video mode won't
be re-programmed and will display "no signal" (displayport whatever the refresh
rate). But I can blindly type on the keyboard to reboot the computer when it
happens.

I am not really investigating since my monitor going in dpms off is quite rare
in my computer usage. Just giving the info that there is maybe a lil pb here
related to this bug.
AMD TAHITI XT
xserver: git
mesa: git 
xf86-video-amdgpu: git
linux amdgpu: amd-staging-next
(I did update with git source code yesterday and performed no test yet on this
matter with the new code).

Nothing abnormal was reported in the logs (if you really want them, I'll
reproduce the pb).

[Bug 106589] HP w2207 monitor not waking from sleep

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=106589

Bug ID: 106589
   Summary: HP w2207 monitor not waking from sleep
   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: tseew...@gmail.com

Created attachment 139653
  --> https://bugs.freedesktop.org/attachment.cgi?id=139653=edit
dmesg on 4.17-rc6

Problem:
After allowing both of my monitors to go to sleep, my HP w2207 is no longer
detected as being connected to the computer, and cannot be woken up. Its
display cable must be removed and reinserted into my AMD gpu for it to be
detected.

Expected:
The monitor, like my other samsung, will wake up and the OS will see it as
connected.

Why I think this is possible to fix in software:
The problem does not occur when using my 660Ti with Nvidia's 390.x driver.

Hardware:
GPU: RX 560 4GB
Monitor 1: HP w2207 (Affected)
Monitor 2: Samsung S23A700 (*Not* affected)

I have tried DVI->DVI and DVI->HDMI cables with the HP w2207, no change in
behavior.

The monitor will not wake even when it is the only monitor connected.

I have tested another monitor (an ancient 4:3 dell) in conjunction with the
S23A700, and both wake normally.

Software:
Mesa version: 18.0
X11 version: 1.19.6
Kernel commandline: See attachment for one example (I have tried disabling
amdgpu.dpm and amdgpu.dc to no effect)
EDID: See attachments
Kernel config: see attachments

The only dmesg output before and after the sleep is:
[drm] SADs count is: -2, don't need to read it
[drm] SADs count is: -2, don't need to read it

Kernels tested:
4.16.9
4.16.10
4.17-rc6
amd-drm-staging-next (current as of May 18th 2018)

No changes between any of them.

I also see that the kernel renames the display after a reconnect, I'm not sure
if that is normal either.

e.g. 

At boot: card1-HDMI-A-3
After unplugging/replugging: card1-HDMI-A-4


Please let me know what additional information or troubleshooting steps you
would like me to take.

Thanks for your time.
