Setting Up Huion WH1409 V2 on Ubuntu (20.04)

This is my second experience using a pen tablet on Ubuntu (which works wonderful). Everything works out the box using the previous Digimend v10 installation. The only change I made is to copy Huion H950p configuration to the following content.

#!/bin/sh
# huiowh1409.sh: configuration file for WH1409 on Ubuntu 20.04, run as: $ ./huionwh1409.sh

#Change DVI-I-1 to what monitor you want from running command: xrandr
MONITOR="DP-1"

# Get pad name, use "lsusb" or "xsetwacom list devices"
PAD_NAME='HUION Huion Tablet'

# get stylus ID
ID_STYLUS=$(xinput | grep "$PAD_NAME stylus" | cut -f 2 | cut -c 4-5)

# map pad to first monitor
xinput map-to-output $ID_STYLUS $MONITOR

# Pad button mapping for Xournal

xsetwacom set "$PAD_NAME Pad pad" button 1 key Ctrl z # undo
xsetwacom set "$PAD_NAME Pad pad" button 2 key Ctrl y # redo
xsetwacom set "$PAD_NAME Pad pad" button 3 key Ctrl shift d # default
xsetwacom set "$PAD_NAME Pad pad" button 8 key Ctrl shift p # pen

xsetwacom set "$PAD_NAME Pad pad" button 9 key Ctrl shift e # eraser
xsetwacom set "$PAD_NAME Pad pad" button 10 key Ctrl 1 # shape recognizer
xsetwacom set "$PAD_NAME Pad pad" button 11 key Ctrl 4 # arrow
xsetwacom set "$PAD_NAME Pad pad" button 12 key Ctrl 5 # coordinate

xsetwacom set "$PAD_NAME Pad pad" button 13 key Ctrl c # copy
xsetwacom set "$PAD_NAME Pad pad" button 14 key Ctrl v # paste
xsetwacom set "$PAD_NAME Pad pad" button 15 key Ctrl shift r # select rect 
xsetwacom set "$PAD_NAME Pad pad" button 16 key Ctrl d # new page after

All 12 pad buttons work without any further configuration! Both USB cable and bluetooth connection also work seamlessly. This WH1409 tablet has a smoother pen (PW500 pen) compared to H950P (with PW100 pen). So far, I am very satisifed by its performance, particularly on Linux-based PC.
