Quack,I was wondering what make my system so peculiar and stumbled onto this bug report:
https://github.com/ckb-next/ckb-next/issues/671
I haven't tried the ckb-next git version yet but it seems strange that simply presenting a device's features differently would break things. If there is a problem in udev or libinput I think it would be good to track before jumping to an easy workaround. So I'm not reassigning yet and I'd be happy to have your input.
