Computer does not shut down completely Kubuntu 25.04

[mchipeur]

I am switching from Windows and I have found that I like the KDE Plasma desktop. I have tried several distros and I like Kubuntu but the shutdown process does not complete - the screen goes black but the LED on the Function key remains on. (I tried KDE Manjero and the laptop completely shut down.)

I searched for info and found references to Ubuntu 22.xx having issues but nothing about Kubuntu 25.04 (something about Nvidia graphics drivers). Unfortunately the instructions were to use command lines to find a log and then do some complicated stuff but I just want switch from Windows - I don't want to learn to operate my computer via command lines. Manjero worked but I thought I might like to use an Ubuntu based distro.

Can someone point me in the right direction to an easy fix?

What do you do to make it shut down?
If you open a terminal and type:

shutdown -h now

What happens?

Also you can turn off the splash screen that shows when you start and shut down so you can see the text messages and see if it hangs up on a certain step in the process.
To do this, edit /etc/default/grub with a text editor like kate and find the line saying

GRUB_CMDLINE_LINUX_DEFAULT='quiet splash'

Edit it by removing the words quiet splash so it reads

GRUB_CMDLINE_LINUX_DEFAULT=''

Save the file and enter your password.

Go to a terminal and type:

sudo update-grub

Enter your password so it can update grub.

Reboot and shut down and watch the text messages during shut down to see if it gets stuck at a certain step.

Thank you bengtang.

To shut off now I press the power button until the LED goes off (about 6 seconds).

I will try your advice but I was afraid that the solution would be command-line fiasco. I was hoping for something as simple as Windows.

I have tried several other Ubuntu based distros since I posted and they all get hung up on shutdown. I may just stick with Manjaro.
