Yes, I saw a segfault when running «xsetwacom --set $id Button 1 "key $anykey"», which gdb revealed was due to XkbGetKeyboard always returning NULL. The only references that came up in a search mentioned Wayland, so my theory was that Archlinux now using libinput as a default was the cause (I thought libinput somehow backs all the Xorg input, but I realize now that I was mistaken). Using «XkbGetMap» instead fixed the issue for me. However I just realized something entirely different may be the cause. I’m using the AdNW [1] keymap (sort of a German dvorak) as installed by running the script in [2]. When I load a standard keymap such as «setxkbmap de», I can no longer produce the segfault using the unpatched version of xsetwacom. I’m not really familiar with Xorg internals. Are you able to make sense of this by any chance?
