Description mightymochigames 2025-12-12 01:37:56 UTC 
SUMMARY
In Fedora 42 KDE Plasma, I am unable to remap the buttons on my drawing tablet pens. This happens on two different systems with different pen tablet manufacturers. The interface looks like it allows me to remap the buttons, but the buttons do not behave any differently. I have tried this with a Wacom Cintiq Pro 24 on a desktop and with a MPP 2.0 pen on an Asus Flow Z13.

STEPS TO REPRODUCE
1. Go to Drawing Tablet settings.
2. Change the intended pen button behavior.
3. Test behavior. I have tested in the OS, Blender, and Krita.

OBSERVED RESULT
Changing the settings has no effect on the pen button behaviors.

EXPECTED RESULT
Changing the settings should actually change the pen button behaviors.

Comment 1 mightymochigames 2025-12-12 01:46:36 UTC 
I noticed I had updates available so I did update, the problem persists.
Comment 2 mightymochigames 2025-12-12 04:21:54 UTC 
I just tested on another laptop with Fedora 43 KDE and a huion Kamavas 16. The same issue persists.

Please run libinput list-devices, and I'll see if there's an obvious issue there.

Huion devices are complex and this is probably broken for a different reason. Please see https://bugs.kde.org/show_bug.cgi?id=513282 for a solution there.

A recent update seems to have solved the wacom cintiq issue as I can now remap the pen buttons for that. But the MPP pen on the Asus Flow Z13 is still not taking new inputs from KDE settings and defaults to Application Defined behavior. Here is the libinput list-devices:

Comment 5 mightymochigames 2025-12-20 01:13:45 UTC 
When running the huion tablet, I now can see one of the buttons remapped to mouse right click on the desktop, but inside applications it either defaults to application defined behavior or appears to stop working. I'm not sure how to quantify that yet aside from it looks like settings are fighting each other depending on what application is open.
