A month or two ago the Huion H610Pro tablet’s buttons stopped working with the input-remapper macros I set up to do useful things. Considerable searching showed that the Digimend kernel driver project previously handling the buttons went inertial two years ago and, apparently, no longer worked with contemporary kernels. Further searching suggested old Huion tablets, which mine certainly is, should be handled by the native kernel / X drivers, so I uninstalled Digimend.
Which produced a persistent error message from the DKMS machinery telling me something awful was happening with the now-missing Digimend.
An Arch Linux BBS thread suggested manually removing various detritus left behind during successive kernel updates in places like /usr/lib/modules and /var/lib/dkms. Given that my desktop box runs the 6.18 kernel, I felt reasonably confident in removing the 5* kernel directories and anything mentioning digimend from those locations.
After the box started up the next morning, all the tablet buttons once again worked the way they use to.
