S3 Sleep on AMD always freezing the Desktop (feddit.de)

I dont know if this is pretty common? I reported a bug about this an eternity ago on Fedora, but it is still happening.

I am also not sure what project is responsible, mesa?

Whenever I sleep my Fedora KDE Laptop, close the lid, open it and it turns on but no input works.

Sometimes my entire screen is corrupted too, like this and often only a hard shutdown fixes it, sometimes it reacts by itself.

Do you know something similar? Where should I report it and how can I circumvent this by now, disable S3 sleep?

Many modern laptops no longer support S3 sleep at all. It is likely to be an issue with the bios rather than a linux project. On my laptop, with Ryzen 7 5825U, I had to give up on S3 and use s2idle. Also had to pass "pcie_aspm=off" as a kernel parameter because it would take ages to wake the ssd without it. Overall works ok. Not as good as S3 but better than nothing.

    Thank you! How do you activate s2idle?

    So to check what suspend states your laptop supports run cat /sys/power/mem_sleep. It should print something like s2idle shallow [deep] with the option that is enabled having [] around it. To change the enabled option run echo "s2idle" > /sys/power/mem_sleep.
