Moving from linux kernel 5.4 to 5.10 causes my screen never to show display again once it has gone to sleep.

As one can see in this video, I can call xflock4 which locks the screen and I'm able to go back when the screen goes to I think screensaver mode.

But doing it while waiting only a few seconds later as the screen goes into sleep mode, I can no longer bring it back. It's stuck at 'screen saver' mode and does not respond to any input.

This happens in Linux 5.10, but not in Linux 5.4.

What should I do?

Move to kernel 5.13 and hope for the best?

First of all, how did you change from 5.4 to 5.10? IS that Manjaro's regular kernel upgrade? If not, why don't you stick to 5.4?

Let me quote from this excellent article:

Quote:

Don't rush to claim that you have found a bug

When you are having problems with a piece of software, don't claim you have found a bug unless you are very, very sure of your ground. Hint: unless you can provide a source-code patch that fixes the problem, or a regression test against a previous version that demonstrates incorrect behavior, you are probably not sure enough.

(...)

When asking your question, it is best to write as though you assume you are doing something wrong, even if you are privately pretty sure you have found an actual bug. If there really is a bug, you will hear about it in the answer.

I saw it in the manjaro kernel menu as 'LTS' and 'recommended', so I would think it's supported.

Linux 5.4 has an issue with snapd that has been solved in Linux 5.10.

I'll go back to Linux 5.4 then.

[update]

Okay, now I'm beginning to really need it.

Code:

$ docker run --runtime=sysbox-runc -it dockerfile

docker: Error response from daemon: failed to create shim: OCI runtime create failed: kernel version check failed: manjaro kernel release 5.4.135-1-MANJARO is not supported; need >= 5.5: unknown.

ERRO[0000] error waiting for container: context canceled

Sorry, which one is the LTS, 5.4 or 5.10?
No, scratch that: which one is the Manjaro default kernel: 5.4 or 5.10?
I seem to remember they ship their own kernel, so unless you have a specific reason to change that, you probably shouldn't.

It's actually rather confusing, Since top download https://manjaro.org/downloads/official/xfce/ leads to
https://download.manjaro.org/xfce/21...4-linux510.iso

But then there's also a minimal LTS linux 5.4 version for at the bottom.

I will ask the manjaro forum.

And this is the answer from someone on the manjaro team:

Quote:

Manjaro ships multiple kernels. All that have the LTS badge can be default, but you can use also the maintained kernels that are not LTS. MHWD kernel is a great tool to see that. You can have them all installed if you want, and test what works best for you.

[update]

There's now a second person claiming to face the same issue.

https://forum.manjaro.org/t/manjaro-...crazy/75442/16

If 5.4 works for you and is one of the officially supported LTS kernels, why not just use that?

Meanwhile, you should definitely do more troubleshooting: try to pin it down on either the kernel or the screensaver/locker used (as one of the posters on Manjaro forums suggested).
General advice for providing output etc. in my signature.
