# To see if the tablet and pen are recognized :
# xsetwacom list devices
#
# To look at the actual config of a component :
# xsetwacom -s get "<component>" all
# The s option can be ommitted, I use it because you need it to see button mapping.
#
# To look at the different paramaters you can configure :
# xsetwacom list param
#
# To look at the keys you can use for the mapping process :
# xsetwacom list modifiers

#
# You can look at the disposition and other stuffs of you tablet on /usr/share/libwacom/<brand>-<model>.tablet
# Exemple, for a Huion H420 :
# cat /usr/share/libwacom/huion-h420.tablet
# There's also a possibility to see an SVG file of the drawing at /usr/share/libwacom/layouts/<brand>-<model>.svg

# Setting up the buttons

# on the tablet (pad)
xsetwacom set "HUION H420 Pad pad" Button 1 key "ctrl" key "s" #top
xsetwacom set "HUION H420 Pad pad" Button 2 key "ctrl" key "shift" key "z" #middle
xsetwacom set "HUION H420 Pad pad" Button 3 key "ctrl" key "z" #bot

# on the pen
xsetwacom set "HUION H420 stylus" Button 3 key "e" #button facing up (not the click button on the top)

# Matching surface area to resolution of the main screen
xsetwacom set "HUION H420 stylus" MapToOutput eDP-1 #eDP-1 is the screen of the laptop, look at xrandr -q to see the one you want
