Blank screen at resume after sustend to RAM

English Install/Boot/Login

Hello there,
After update 3 days ago, I get a blank screen at resume after suspend to RAM.
I can ssh the box tried top when working fine and when there is the issue. At first both output are same.

Do you have a screen saver enabled? If so could you try disabling it an try again?

4

Yes I had screensaver on.
I switched it OFF and tried few times, unfortunately same issue, black screen.
The OS is working, I have to key Ctrl-AltGr-Delete and press twice left arrow to restart the box.
Any other idea?

5

I very infrequently run into something like that myself but without suspend to RAM , just the monitor goes to sleep and does not wake up.

I have tried switching off/on the monitor with the button on the monitor but that does typically not help, what helps is disconnecting the cable and reconnecting it. Not really a nice solution but can you give these two methods a try?

6

I tried different cases but nothing better.
While the issue, monitor connected, screen black, I switch OFF the monitor then ON, it says “No signal”.

7

Assuming you tried also unplugging the monitor cable and replugging it and that that also did not work I am not sure I can further help.

If the problem is only now and then it would make sense to study the difference in the journal for a successful resume versus on where the screen keeps blank.

As you have ssh access it would also make sense to use the ssh session to suspend the session once more an see if the next resume results in a working monitor.

Searching “monitor does not come up after resume” on the Internet gives also all kind of suggestions but most of them seem to be specific for certain hardware.

Thanks marel for your help.
I tried the previous kernel in the boot; Nothing better.
Then I tried the current kernel but in recovery mode; Resume is good, screen working.
In the /var/log/Xorg.0.log file when normal boot there is no EDID message nether after resume but in the recovery boot there are a lot of EDID messages and after resume one EDID message.

Unfortunately I have no knowledge to go further.
Any help
Thanks

I did a bit further searching, this time on “amdgpu driver wake up” and the tells me your are not the only only with these kind of problems. Not sure if they are the same but what is suggested on this page might be worth a try: AMD GPU Wake from sleep intermittent issue (unresponsive, related to vblank) - Graphics & Display - Manjaro Linux Forum

I also found there is a amdgpu_top tool, no OpenSuse package but you can build it yourself. Would be good to give that a try when the monitor does not come up and using ssh to get into the machine.

I just upgraded the box to Leap 15.5
I had an issue, long time, ~25s between background image and icon.
Now issue is gone.
However, the issue in this thread is still present.
From here, I tried

I don’t know how to install amdgpu_top. Could you help?

On that you should do really some searching, my search gives among others:

I am not surprised you can not install amdgpu_top, see my previous reply, “you can build it yourself”.

From the link you provided
https://davidtsadler.com/posts/linux/2021-06-05/xrandr-failed-to-get-size-of-gamma-for-output-default/
I removed “nomodeset” from grub

sudo vim /etc/default/grub

Now I have

GRUB_CMDLINE_LINUX_DEFAULT="splash=silent resume=/dev/disk/by-uuid/9ebf81e0-1f57-4d3d-8434-3da6e898daa6 preempt=full quiet security=apparmor mitigations=auto"

After reboot everything work fine.

Thanks a lot marel for your help.
