SUMMARY I am using the digimend drivers with the Huion H640P tablet (https://github.com/DIGImend/digimend-kernel-drivers, which I built the latest version of just now). There are four devices exposed by the drivers for this device: ~ » xsetwacom --list devices Tablet Monitor stylus id: 11 type: STYLUS Tablet Monitor Pad pad id: 12 type: PAD Tablet Monitor Touch Strip pad id: 13 type: PAD Tablet Monitor Dial pad id: 14 type: PAD By inspection, I found that kcm-wacomtablet set the buttons on device 14, which makes them not do anything. I then tried setting it on the other devices exposed by the tablet, and found that setting it on device 12 is correct: ~ » xsetwacom --get 14 'Button' 1 key +Control_L +Shift_L +p -p ^^^^ this is what I have in the kcm settings ~ » xsetwacom --set 14 'Button' 1 'key z' *press it* (nothing) ~ » xsetwacom --set 13 'Button' 1 'key z' *press it* (nothing) ~ » xsetwacom --set 12 'Button' 1 'key z' *press it* (z) STEPS TO REPRODUCE 1. Set an Express Button in "Graphic Tablet - System Settings" on a Huion H640P 2. Press the button OBSERVED RESULT Nothing happens, because the settings panel set it on the wrong device. EXPECTED RESULT I would like it to set on the correct device. I know that this device is sorta a weird thing and might need some workaround code :/ SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.25.3 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 Kernel Version: 5.15.55-2-lts (64-bit) Graphics Platform: X11 ADDITIONAL INFORMATION
Oh, bonus madness: the buttons are in discontinuous order!! The buttons that exist are 1, 2, 3, 8, 9, 10, which are just the six buttons on the left in order top to bottom. There is no obvious reason that they are in a weird order. But this might be something this implementation might run into as well.
