Long black screen after login and KDE session crash after some minutes

[Takinya]

Cachy OS randomly lockscreen and freeze

Okay, I have now disabled my iGPU in the BIOS settings and set Cachyos/KDE to always start a new session after restarting and not try to restore an old one. I have now been able to restart twice without any blackscreens or freezes. I sincerely hope that this helped.

Maybe worth trying out. Currently i do not have the blackscreen and freezes any longer. (Fingers crossed it stays this way :D)
