(https://ibb.co/G28MNXx) OBSERVED RESULT Only 8 buttons are configurable. EXPECTED RESULT Ability to configure all 12 buttons. SOFTWARE/OS VERSIONS Operating System: Fedora Linux 40 KDE Plasma Version: 6.1.1 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 Kernel Version: 6.9.5-200.fc40.x86_64 (64-bit) Graphics Platform: Wayland
This is most likely a libinput issue, but to make sure I suggest running something like `libinput debug-events` and press your buttons one-by-one to see if they're picked up. I think `evtest` may help here as well.
(In reply to Joshua Goins from comment #1) > This is most likely a libinput issue Thanks for the reply. You are right, I checked their issue tracker and found an existing issue ( https://gitlab.freedesktop.org/libinput/libinput/-/issues/908#note_2305882 ), just in case someone needs it, the next comment in the linked issue has a workaround. `libinput debug-events` did not print anything for buttons that are not present in the systemsettings, `evtest` did print something, output is the same as in the linked issue.
Thanks for going as to seek out the upstream libinput issue, that really helps
