Ryzen 7490HS laptop, not waking up from sleep

[newuser776]

Hi,

new kubuntu 23.04 install, with the default 6.2 kernel or with the 6.3.4 from https://code.launchpad.net/~cappelik...ive/ubuntu/ppa the system goes to sleep after some time away,
but it does not react to keyboard or mouse to get back alive.

with my last i5 6200 laptop i sometimes had to touch the power button just before moving the mousepad to wake it. Doesn't work either.

i am aware that this is new hardware and probably a kernel or maybe linux-firmware? problem, but since my google queries haven't shown any hits im asking here.

long time linux user with ubuntu - first time kubuntu - love it

Welcome!

Same result with something like this (more up-to-date stuff…)?

Als Live USB System kann ich das ausprobieren, aber laut dieser Seite: https://software.opensuse.org/package/kernel-default gibts dort auch nur den 6.3.2 kernel
Welche anderen libraries/Programm können noch für nicht funktionierenden resume verantwortlich sein?

Translation:

I can try it as a live USB system, but according to this page: https://software.opensuse.org/package/kernel-default there is only the 6.3.2 kernel
What other libraries/programs can still be responsible for non-working resume?

It is mostly hardware support in the kernel AFAIK, but probaly not the kernel alone entirely (Frameworks, settings, etc. … ?).
Linux is mostly worse compared to Windows and both are much worse compared to macOS regarding this.
(Laptop) power saving functions also rely heavily on the UEFI/BIOS (ACPI) and how the manufacturer implements them.

It is merely a suggestion to try a more "leading/bleeding edge" distribution for recent hardware (and the easiest way to do this would be a live medium) to generally check if this makes any difference. And to try going from there with the result of this test.
