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 boot
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.

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 ...
@jose: It seems that I already have installed a "amdgpu_drv.so"
containing your mentioned patch.
My package manager claims that I have installed "xserver-xorg-video-
amdgpu-hwe-18.04_19.0.1-1ubuntu1~18.04.1_amd64.deb" with version
"19.0.1-1ubuntu1~18.04.1". I compared the binary deb-package of my
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"
MatchDri
@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"
evaluated fr
@Richard: Did you mean Ubuntu 20.04? What kernel have you running (uname
-r)?

Title:

@Richard:
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 suspend.
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
first time
Yes it was only a workaround. The workaround running well for a few days
until this update:

Back to freeze on resume.
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 no

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

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
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
