Hey all,

So since I've installed KDE Neon I've had this hang when turning off or rebooting for about 10 seconds, unsure why. However I wondered if anyone else is having this issue and what I can do to find out why.

I am using a custom kernel called linux-surface because the surface device doesn't work well without it, overheats, doesn't support touch screen etc.

Thanks!

An update to this, when I use poweroff in terminal, that shuts down instantly, however when I use the shutdown button on the start menu, it hangs for about 10 seconds on the desktop after it closes everything, it then moves to a black screen showing me shutting down services, however it moves too quickly for me to see what it might've hung on.

I was following some solutions on here which didn't work unfortunately: https://ubuntu-mate.community/t/20-04-h ... tart/23269

That problem is persistent on god knows how many setups. I don't have the prob anymore, but I did before. At the time there was no bug fix ( still isn't for that matter) and I posted a workaround here which involved a zenity script for logout/shutdown/reboot. Works flawlessly. There's also a compact shutdown widget https://store.kde.org/p/1483671/ which seems to do the trick.

That is because when you click on, for example, restart button, it does:

Code: Select all

qdbus org.kde.ksmserver /KSMServer logout 0 1 1

more about https://itectec.com/ubuntu/ubuntu-how-to-safely-shutdown-reboot-logout-kde-from-the-command-line/
which saves the session, ends all processes safely etc.
And when you type

Code: Select all

reboot

in terminal it just reboots.

Now i would like to know, if there was a way to map the button to do the

Code: Select all

reboot

command instead of

Code: Select all

qdbus org.kde.ksmserver /KSMServer logout 0 1 1

?

I'm not currently on kde, but you could have a look in system settings>startup/shutdown>ssdm. At the bottom, click "behaviour". If I recall correctly, there's something like a shutdown and reboot command. If I'm not wrong about that optional setting, using systemctl reboot and systemctl poweroff could do the trick. You'd probably have to make a little script fot it. Nothing fancy. Something like:
#! /bin/bash
systemctl reboot
..for the reboot. Make it executable and point the command in ssdm to that script.

Quickly grabbed a kde lappie.

Unfortunately that didn't work.

After some update, that same problem is back. Regular logout/reboot whatever worked normally for a while but the "hang for...secs" is back on mine. Reverted back to my script and works just fine, no lag. https://imgur.com/a/oEG3815
This is the bash (requires zenity)
#!/bin/bash

shot_type=$(zenity --list --radiolist --height=200 \
--column "Select" --column "One of these..." --width=250 \
TRUE "Logout !" \
FALSE "**** reboot !" \
FALSE "Shutdown Goddammit !" \
--separator=":");

case $shot_type in
"Logout !")
loginctl terminate-user "username"
;;
"**** reboot !")
systemctl reboot
;;
"Shutdown Goddammit !")
systemctl poweroff
;;
*)
esac

I've read somewhere thats the cause of this problem is KDE Connect. I unninstal KDE Connect with Muon and now both shutdown and reboot options work like they have to do. Fast.

Well, if you don't use connect, it's a sollution.
