I got a Huion H420 graphics tablet and I need to remap the keys. There are three key, which are mapped as left click, middle click(presumably) and right click.

I need a way to remap these keys to any other key on the keyboard, as I want to use it for graphics design.

I'm running Ubuntu 17.04, and the tablet shows up with ID 17 when I run xinput list.

What worked for me after reading from various places viz. bunnyrules's answer and the links therein, and this:

  1. Install DIGImend drivers first from here. I used the .deb (v7) file and it worked fine. You might also want to remove hid-huion module if you have it installed. Check with lsmod. Also you might need libusb and wacom binaries and libraries.

I had the following installed on 16.04:

libwacom-bin/xenial-updates,now 0.22-1~ubuntu16.04.1 amd64 [installed,automatic]
libwacom-common/xenial-updates,xenial-updates,now 0.22-1~ubuntu16.04.1 all [installed,automatic]
libwacom2/xenial-updates,now 0.22-1~ubuntu16.04.1 amd64 [installed,automatic]
switchboard-plug-gcc-wacom/xenial,now 0.2.0-0~77~ubuntu0.4.1 amd64 [installed,automatic]
xserver-xorg-input-wacom-hwe-16.04/xenial-updates,now 1:0.34.0-0ubuntu2~16.04.1 amd64 [installed]
  1. Configure tablet in X: sudo vim /etc/X11/xorg.conf.d/50-huion.conf.

Use this configuration:

# Huion tablets
Section "InputClass"
    Identifier "Huion class"
    MatchProduct "HUION"
    MatchIsTablet "on"
    MatchDevicePath "/dev/input/event*"
    Driver "wacom"
EndSection
  1. Now logout and login.

xsetwacom should now detect the H420.

% xsetwacom --list
HUION H420 Pen stylus                   id: 10  type: STYLUS
HUION H420 Pad pad                      id: 11  type: PAD
  1. Now you can remap buttons:

ex. if you want to set Button 1 to page up.

xsetwacom --set 'HUION H420 Pad pad' Button 1 "key +pgup"

The format is + for press - for release followed by X11 KeySyms. For the full list see xsetwacom --list modifiers and also man xsetwacom (see PARAMETERS section)

You can also change mappings of the pen stylus buttons :). Button 1 is the pen tip and 2 and 3 are the ones on the pen.

If you screwed up a mapping, you can reset it like this:

xsetwacom --set 'HUION H420 Pen stylus' Button 1 "button +1"
