Hello all!

I’ve a problem with the wake up from screen sleep (not whole computer sleeo,
only display) and latest kernels. When the computer screen goes to sleep it
won’t wake up anymore. No mouse cursor nor i can change to 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 or 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, i
think before 6.6.x) it does work. I've tested the same behaviour on OpenSUSE
Tumbleweed and Arch Linux. Also i changed to Wayland, but the same problem.

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. Thank you very much.

Best regards!
