Slow shutdown problems in kde plasma with sddm

Whenever I try to shutdown my pc I get a message like -
"Starting version 249.5-3-arch
/dev/sda3: clean, 458192/30228480 files, 32189479/120907009 blocks "
and it basically takes my pc 2 minutes to shutdown.
People already made a lot of bug request regarding this -

Any clue ?

There's measures in #1460 that should mitigate this issue.

Also in Plasma Workspace we added f377696bff39e35ae0f7ae6104d8732b3856744e exactly for that.

Could you try enabling systemd boot for Plasma and see if it addresses the problem for you?

I wouldn't want to be responsible for your system, let me comment in the bug reports you mentioned.

People having the same issue here I think it is a sddm issue or a kwin issue - https://bbs.archlinux.org/viewtopic.php?id=259577

FTR, I can reproduce this issue with x11 greeter but not wayland greeter. https://bugs.kde.org/show_bug.cgi?id=445449#c23

With X11 greeter, Xorg terminates and SDDM decides to restart it, at which point the shutdown hangs.

Just started having the same issue today, because I switched to Wayland. Screen turns black and backlight doesn't when initiating shutdown/reboot, only after a couple of minutes it completely does. Doesn't happen on X11 session, shutdown/reboot is quick.

Having the same issue on Gentoo https://bugs.gentoo.org/833059

Started having exact same issue yesterday on Arch with KDE Plasma on Wayland

This appears to have been remediated for Fedora Rawhide.
