KDE crash on adjusting volume

This doesn't happen everytime, but it's annoying nevertheless whenever it does - Adjusting the volume crashes KDE and gets me back to SDDM login screen.

If specifics are required : I adjust the volume by holding the keyboard media keys or the the macros on my mouse. The media key is actually Fn+ F12 for vol up and Fn+F11 for vol down (yeah it's a mac friendly kind of keyboard) . I have this keyboard connected via bluetooth.

Is this a known issue? Or is it possible to log this crash?

Send a dmesg log when this happens. Probably a kernel problem (this is not the official kernel)


Umm...sorry linux noob here. Not sure how to do what you just suggested.

I have to use this kernel since it comes with custom patches to enable fan curves on my particular laptop. Otherwise the fans barely spin even on high load. Maybe from kernel 5.16 or 5.17 those patches might get merged with other more widely supported kernels like zen.

When this problem occurs, simply type the following into the terminal as root or sudo:


And write me back with the whole output of this command

I am just logged out and sent to sddm login screen when it happens. Would this count after logging in(brand new session)?

Should be. You can also press ctrl + alt + F3 and log into the tty as root. Since this output might be long, you can do
dmesg > output.txt and then open the file and copy the contents.


@zoeruda @Pheidologeton

Couldn't paste the giant file here. Tried a pastebin. I hope dmesg logs don't contain any sensitive information about my PC and that's why you guys asked for it.

What happened : Booted and logged in, tried watching some video I think, increased volume with media keys on BT keyboard and it crashed.
On relogging, I removed the dmesg warning with some command and outputted the dmesg log. That's all the events which occurred.

This is very strange, I don't see any problem in dmesg. Try boot from the official kernel or linux-tkg from chaotic-aur, and try changing the volume on them.

Sorry for late reply. It is very strange indeed.

I'll consult the maintainers of the kernel if their utility (asusctl) lets the fan curves work on other kernels, and try to replicate the issue on the zen kernel. I don't like the fans being idle on my laptop that's why I have to use this kernel with custom patches.

Is this a new keyboard for you? I have a bluetooth Keychron as well, and it required a little configuration to get the F-keys and multimedia keys working correctly on Linux.

Here's what I found for setting up the K2:

On Linux, the Keychron K2 doesn’t register any of the F1-F12 function keys as actual F keys, instead, treating them as multimedia keys by default. Here’s how to fix it!

They keyboard has 2 modes: Windows/Android and MacOS, but neither mode worked properly out of the box.

To fix this:

Set the keyboard to Windows mode via the side switch
Use Fn + X + L (hold for 4 seconds) to set the function key row to “Function” mode. (usually all that’s necessary on Windows)
echo 0 | sudo tee /sys/module/hid_apple/parameters/fnmode
Once complete, my F1-F12 keys work properly, and holding Fn turns them into multimedia keys. You can use the evtest utility to check how keyboard keys are registering until you get the above combination of settings configured properly.

To persist this change, add a module option for hid_apple:

echo "options hid_apple fnmode=0" | sudo tee -a /etc/modprobe.d/hid_apple.conf
You may need to rebuild your initramfs if hid_apple is included.

ubuntu: sudo update-initramfs -u

arch: mkinitcpio -P

I'm not sure if the issue you are experiencing could be caused by the keyboard not being configured correctly, but I figured I would mention it in case it was something that had been missed.

I've already fixed the function key problem on this keyboard. It is registered as an Apple keyboard so yeah pretty much used the same command as you mentioned.

It's not just an issue with keyboard, I have applied the volume adjustment to my mouse buttons and that crashes it too. After 1 crash, it works fine.
