CachyOS can't power off properly and stuck with black screen

Issues & Assistance
1

Hello. I fresh installed the OS but have an issue. After I try to shutdown a PC it stuck on: black screen, black screen with terminal “_”, sometimes I have this text “[ 37.015726] reboot: Power down”. I’ve tried change some ACPI parameters like: off, force, noirq, strict in /etc/default/grub, apm=power_off, tried reinstall system to systemd-boot and do the same in /boot/loader/entries but nothing. Tried in BIOS change ACPI parameters, change them to auto, only CPU, only RAM and both, disable fastboot, quiteboot but nothing too. Is someone have an idea how can I solve his issue?

Can you give some logs from boot session that has failed shutdown?

e.g. for previous boot

journalctl -b -1 | paste-cachyos

Oh wait… Why are you using the handheld kernel? It’s not meant to be used on desktops. Did you install the handheld ISO?

There isn’t really anything obvious in the journal, atleast for me. You can try to use the wayland backend in SDDM by following SDDM - ArchWiki.

If that doesn’t work, try to check if its a kernel regression by updating to the latest (6.10.8) or installing the LTS kernel linux-cachyos-lts.

^^ The steps above are also only relevant if you’ve installed the Desktop ISO on your machine.

It’s strange because I kind of chose the desktop edition… I’ll try install the LTS kernel of CachyOS and see what changes

All the same after install LTS kernel and adding code below to /etc/sddm.conf

[General]
DisplayServer=wayland
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell

[Wayland]
CompositorCommand=kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1

Add this to a new file 10-wayland.conf in /etc/sddm.conf.d, not sddm.conf
