[chris <1920573@xxxxxxxxxxxxxxxxxx>]

I installed libwacom-dev but result did not change.

I upgraded to kernel 5.11.8-051108-lowlatency and now the stylus works
normally: pressure, and both in-line buttons.

Title:
  20.10 Stylus input (wacom screen) instantly freezes OS

Status in Ubuntu MATE:
  Invalid
Status in libwacom package in Ubuntu:
  New
Status in xf86-input-wacom package in Ubuntu:
  New

Bug description:
  Previously on 20.04 stylus input with Wacom integrated display (not a
  pad or separate device) worked great.

  Currently on 20.10 any stylus input including near hover without
  physically touching will instantly freeze/lockup the OS forcing hard
  reboot/power off/on to recover.

  Kernel might (?) be confusing touch input with stylus input in the
  same moment as described here (???):
  https://www.linuxquestions.org/questions/linux-hardware-18/touching-
  wacom-tablet-crashes-linux-4175571470/.

  Device is HP Envy Note 8 using official HP Stylus, Ubuntu Mate 20.10.
