X200 Tablet Pen not recognized
Wacom Pen in Lenovo Thinkpad X200 Tablet is not recognized by libinput. It works fine on X11. This issue is probably missing some information that you need, but I don't know what exactly you need and where to get it.
Steps to reproduce
Boot Linux on a X200 Tablet and list devices known to libinput. It does not appear.
libinput version you encountered the bug on
Lenovo Thinkpad X200 Tablet, running Void Linux with kernel 5.0.17
I couldn't find any mention of the device in any logs, not even something about missing tablet capabilities.
