Description Benedikt Winder 2023-12-19 19:05:17 UTC 
Hello all!

I’ve a problem with the wake up from screen sleep and latest kernels. When the computer screen goes to sleep it won’t wake up anymore. No mouse cursor nor i can change the tty (Strg + Alt + F1 …). The journals logs are also empty and only a hard reset helps. I’ve tested it with the lastest Linux Kernel 6.6.6 and 6.6.7. Funnily if the whole computer goes to sleep (for example Sleep, Hybrid Sleep and Hibernate), and i disable Screen Sleep before, the screen wakes up. The problem exists only when the screen goes to sleep. With older kernels (i don't know the exact version) it does work.

Info for my System:

Graphics Platform: X11
Processors: 16 × AMD Ryzen 7 PRO 7840U w/ Radeon 780M Graphics
Memory: 30,1 GiB of RAM
Graphics Processor: AMD Radeon Graphics
Manufacturer: LENOVO
Product Name: 21F80041GE
System Version: ThinkPad T14s Gen 4

Maybe someone have an idea or an tip where i should submit a bug ticket. Thank you very much.

Best regards!

Is it still a problem with the very latest kernel?  Try the one in OBS Kernel:stable repo:
