i have narrowed the hang down to kde using turnstiled. i am running openRC init on Debian with KDE Plasma (wayland). when i use the menu shutdown or reboot command, screen goes black. on either if i hit the power button it would continue shutdown (obviously not a reboot like i might want sometimes) and the program turnstiled would show as shutting down. so it appears turnstiled is the hang. this is new with the testing repos version of kde-plasma as i was running the stable trixie without the prog being loaded into /etc/init.d. the workaround for now is running;
sudo openrc-shutdown -r now
from terminal “-r” for reboot or “-s” for shutdown - if you are trying to keep all system dbus stuff intact from kde install.
with some research, turnstiled seems to be doing something like sddm, but kde is using both now?! i decided to just disable turnstiled with the command
sudo openrc-update del turnstile
if i need to reenable it for some reason:
sudo openrc-update add turnstile default
however, since disabling i have not noticed any issue with user accounts or logging in/out with and the shutdown and restart buttons from menu do what they are supposed to do.
i am assuming that this is due to an openrc/systemd discrepancy, but could be a bug. i am leaving this here for others running openrc and not systemd in case you have the same issues.
