kcm-wacomtablet does not work with the Wacom One Pen Dispaly 2023 models. The device is correctly detected and operational, but none of the settings on kcm-wacomtablet has any effect. I can still use xsetwacom to change the settings. Older device like Cintiq Pro 24 are not affected. Installing xorg-xinput did not help. xsetwacom list devices Wacom One 13 Touch (DTH134): Wacom One pen display 13.3" with touch Pen stylus id: 21 type: STYLUS Wacom One pen display 13.3" with touch Finger touch id: 22 type: TOUCH Wacom One pen display 13.3" with touch Pen eraser id: 32 type: ERASER Wacom One 12 (DTC121): Wacom One pen display 11.6" Pen stylus id: 21 type: STYLUS Wacom One pen display 11.6" Pen eraser id: 22 type: ERASER Operating System: Manjaro Linux KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.113.0 Qt Version: 5.15.12 Kernel Version: 6.7.0-0-MANJARO (64-bit)
Installing xorg-x11-drv-wacom and libwacom-utils (did not test individually) fixed my issue Thankfully.
