KMS and DRM have nothing to do with input devices.
The lowest level test for input devices is evtest (sudo apt install evtest), which will print out all incoming events for the selected input device.
Depending on which libraries you're using, many will then go through libinput. "libinput debug-events" will print out all events that it handles.
It is not uncommon for HDMI touchscreens to have a "mouse mode" as well as "touch mode", and that will change the type of events that it generates.
