This is probably just a typo in your e-mail, but the service is 
name inputattach-service-type (no third hyphen).

I don't own an X200T, and I don't know which guide your following, 
but a random search led me here[0].  They use ‘--w8001’ while our 
service defaults to ‘--wacom’.

Does passing ‘(type "w8001")’ to inputattach-configuration change 
a thing?
