Since beginning of September the bug disappeared for me. I'm not sure
what update caused it but the usual suspects are: linux-
image-5.4.0-45-generic:amd64 (5.4.0-45.49~18.04.2, automatic) with its
kernel module amdgpu.ko or some xorg-...-hwe parts or a combination of
them.
But I tried with a
For all who used the workaround #61: The current update xserver-xorg-
video-amdgpu-hwe-18.04:amd64 19.0.1-1ubuntu1~18.04.1 19.1.0-1~18.04.1
overwrites the file /usr/lib/xorg/modules/drivers/amdgpu_drv.so (file
date May 21 09:16) and the bug returns again.
It is one step forward one step back ...
I can confirm that #61 removes the bug.
I'm running Kubuntu 18.04 with a hwe kernel 5.3.0-51-generic
#44~18.04.2-Ubuntu. (Not 5.3.0-53 because it contains a power off bug.)
Great! Now I hope it will find a way to an "official" update.

@jose: The above workaround seems to be related with your patch
mentioned at #42.
The function "amdgpu_present_check_flip()" returns prematurely if the
variable "info->allowPageFlip" is set to false. "info->allowPageFlip"
contains the evaluation of the configuration "OPTION_PAGE_FLIP"

At least for me I found a reproducible workaround for the resume bug. I
found it more or less with try and error.
I added the option "EnablePageFlip" to the configuration file
"/usr/share/X11/xorg.conf.d/10-amdgpu.conf" like this:
Section "OutputClass"
Identifier "AMDgpu"

My package manager claims that I have installed "xserver-xorg-video-

I tried your suggestion without luck. The screen remains black, the
backlight was switched on. To verify I tried multiple times.
The only true workaround (with KDE) is to switch the compositor off
before turning into sleep. You have to switch the compositor on after
return from
@jose: I'm not able to manage a setup to verify your reported bug fix.
Sorry.

I can confirm that with switched off compositor (KDE, Shift-ALT-F12)
resume is working. But I think the compositor act as trigger only and is
not the reason for the bug.
I've attached the relevant journalctl output of a current unsuccessful
resume. I started the sleep at 13th april about 20:28:06
P.B. I tried to verify your observation. Without luck. First I generated
a Windows-10 bootable USB drive and managed to install and run the "AMD
Driver Auto-detect tool". On Windows it was successful to set the
computer into standby and resume. Then I've done a warm-start of the
computer an booted
This is a very interesting observation! In one of my previous posts I described
the fact that after the first unsuccessful resume and a following soft-reset
with Alt+SysReq+B all subsequent resumes will succeed.
My guess was that there was something changed in the GPU's hardware registers
The above mentioned workaround (#27) is working again after this

Yes it was only a workaround. The workaround running well for a few days
until this update:

Sorry, I made a mistake I'm running kubuntu (not Ubuntu like mentioned
in #24).
Indeed I can confirm that with a switched off compositor resume will
work. And I can confirm that resume only fails the first time after a
power up reset of the computer. When the screen turn blank after the

I'm running Ubuntu 18.04.4 LTS on a Lenovo Desktop V530-15ARR with AMD
Ryzen 5 2400G with Vega 11 Graphics and a kernel 5.3.0-28-generic.
With a kernel 5.0.0-29 suspend and resume were perfect (from the users point of
view). But I had sometimes graphic freezes during
