DPMS not work

[csablak]

I changed my PC: ASUS PRIME B450M-A II, Ryzen 5 4600G with Radeon Graphics

Code: Select all

$ lspci -v | grep VGA
09:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Renoir (rev c9) (prog-if 00 [VGA controller])

I also bought a new nvme M2 SSD and installed Mageia 9 with KDE Plasma on it.
It is connected to my Aopen 24CL1Y monitor with the previous HDMI cable. There was no problem with the old motherboard and the same
cable, but now despite this:

Code: Select all

$ grep DPMS /var/log/Xorg.0.log
[    10.713] (II) AMDGPU(0): DPMS capabilities: StandBy Suspend Off
[    10.764] (**) AMDGPU(0): DPMS enabled
[    10.779] (II) Initializing extension DPMS


putting my monitor to standby doesn't work. Or it happens, but at that moment the image comes back. Lightdm
login screen. So the lock is there, but the monitor doesn't stay on standby.

"$ xset dpms force standby" turns off the screen for a moment, but it comes back on even though I don't touch the mouse.
The command "$ sleep 2; xrandr --output HDMI-A-0 --off; read -n1; xrandr --output HDMI-A-0 --auto" also turns off the monitor,
which it also shows by displaying the usual pictogram in the upper left corner. But then the picture comes back, but the command line
doesn't.
As if the program is still running. If I touch the mouse, I get the a prompt back.

If it worked with this cable on my previous machine, I don't blame the cable. There was a twist in the story.
My previous machine had an Nvidia GT710 card, to which I connected two monitors. But since there was only ONE HDMI port
on the card, so I used a dvi-to-hdmi adapter for my primary monitor, which is the current Aopen. And the standby worked mode.

The question arises, why doesn't my monitor stay ready once it's there? UEFI BIOS setting?
I start grub like this:

GRUB_CMDLINE_LINUX="tsc=nowatchdog"
GRUB_CMDLINE_LINUX_DEFAULT="root=UUID=blabla ro quiet noiswmd noresume pti=auto audit=0"
GRUB_CMDLINE_LINUX_RECOVERY="failsafe modeset xdriver=vesa"

I disabled eeepc_vmi because it caused problems.

Please try without the dvi-to-hdmi adapter.

Also for the time where you send your monitor to standby, some journal logs would be required. You can also keep the following running

Code: Select all

kscreen-console monitor

while you send your monitor to standby

Hello doctor5000!
As I wrote, I used the dvi-to-hdmi adapter for the configuration of my previous machine. I don't use it anymore because I don't use two monitors either.
The kscreen-console monitor only prints this and does not return the prompt. I have to cancel with Ctrl-C.
Remember to enable KSRandR or KSRandR11 in kdebugdialog
Okay then, let's find out where this KSRandR is?
There is no kdebugdialog command, only kdebugdialog5. By calling this, a window will appear in which you can select a lot of things, what debug, but there is no randr or screen.

The kscreen-console monitor only prints this and does not return the prompt. I have to cancel with Ctrl-C.

That's what it's meant for, it shows you the events that kscreen acts upon. Leave it running, and trigger the standby as you normally would. Then check the output apart from the first line and post it here.

The first line of output is irrelevant.

Unfortunately, I have bad news. I set the power management to turn off the display for 1 minute and lock the screen for 2 minutes.
After doing that, I started the kscreen-console monitor command and left the machine like that. Before long the monitor went dark and immediately after that the lock screen appeared. I waited another minute and moved the mouse. I typed in the password, and I can see that the console still only shows the irrelevant sentence

Hmmm seems kscreen-console does not output anything more at all, also not for config or outputs. Only for bug which is just the output of xrandr.

So some regular journal logs would be helpful.
