Features ↑

• Supports multiple tablet models
• Precise cursor positioning
• Full pressure sensitivity
• Both stylus buttons
• Compatible with multi-monitor setups
• Customizable buttons and scrollbar shortcuts
• Multiple sets of shortcuts
• Optional desktop notifications
• Versatile configuration file

Usage ↑

• Follow the requirements: Install the dependencies and the xorg extra code.
• Download this repository (You only need huion-tablet-driver.py and config.ini).
• Edit config.ini to match your tablet, multi-monitor setup and desired shortcuts.
• Run sudo ./huion-tablet-driver.py (needs superuser privileges)

Requirements ↑

Dependencies ↑

• python version 3.5 or greater

• uclogic-tools (read why)

  # Installation from source: install dependencies, clone, compile & install
  
  $ sudo apt install make automake gcc pkg-config libusb-1.0-0-dev  # For ubuntu
  
  git clone https://github.com/DIGImend/uclogic-tools
  cd uclogic-tools
  autoreconf -i -f && ./configure --prefix=/usr/local/ && make
  sudo make install
  

• xinput

• evdev

• python-evdev

• pyusb

• numexpr

• xdotool (optional, for button shorcuts)

• notify-send (optional, for desktop notifications)

• xrandr (optional, for monitor configuration) (and arandr)

Install packages in Archlinux:

$  pacman -S xorg-xinput xf86-input-evdev python-evdev python-pyusb xdotool \
libnotify xorg-xrandr arandr python-numexpr

Install packages in Ubuntu:

$ sudo apt install xinput xserver-xorg-input-evdev python3-evdev python3-usb \
xdotool libnotify-bin arandr python3-numexpr

Xorg Extra Code ↑

You will likely also need to add some code to the Xorg server. Create a new file in /etc/X11/xorg.conf.d/evdev-tablet.conf with the following content:

Section "InputClass"
	Identifier "evdev tablet catchall"
	MatchIsTablet "on"
	MatchDevicePath "/dev/input/event*"
	Driver "evdev"
EndSection

Troubleshooting ↑

My tablet doesn't provide any inputs despite all my debugging efforts

Maybe you're connecting the table through a USV hub, or USB docking station? This is known to have caused problems in the past. Try plugging the tablet directly to the computer.

/usr/local/bin/uclogic-probe: not found

You eiher need to compile uclogic binaries (see Dependencies), or they are installed in a different location. For example Debian 10 automatically installs them under /usr/bin/. Try updating the path in the config.ini file, which by default is: uclogic_bins = /usr/local/bin.

Config Examples ↑

Multi-Monitor ↑

If you have a multi-monitor setup, edit your copy of config.ini with the correct values for your particular setup.

# Multi Monitor Configuration
enable_multi_monitor  = true
enable_xrandr         = false
current_monitor_setup = [monitor_3]

You'll have to customize your current monitor setup, by modifying one of the existing examples in the section 3 of the config.ini file.

More information about multiple monitors in the wiki

Shortcuts ↑

To customize the shortcuts associated with the buttons and the scrollbar, edit the file config.ini, and use the xdotool syntax for the buttons actions.

First, assign the menu you're going to use as the starting menu.

Example with a Single Buttons Menu

start_menu = [menu_simple_10b]

[menu_simple_10b]

# upper buttons
b0 = key Tab           # hide interface
b1 = key r             # rect select (gimp) & pick layer (krita)
b2 = key ctrl+x        # cut
b3 = key ctrl+c        # copy
b4 = key ctrl+v        # paste

# scrollbar
su = click 4           # mouse wheel up
sd = click 5           # mouse wheel down

# lower buttons
b5 = key ctrl+z        # undo
b6 = key ctrl+y        # redo (gimp)
b7 = key ctrl+shift+z  # redo (krita)
b8 = key 4             # turn left (krita)
b9 = key 6             # turn right (krita)

See an example with multiple menus in the wiki

Ubuntu Example for GT-116 ↑

Tested on Ubuntu LTS 16.04

First, adapt the parameters in config.ini to your tablet model. In case of a Huion Kamvas Pro 12" (GT-116), you could change the following options to use the 5 buttons menu for Gimp and Krita.

current_tablet = [tablet_gt116]
...
enable_multi_pointer = true
...
start_menu = [menu_5b_multi]

After doing all the pre-requisites listed above, copy the 3 files TabletDriver, config.ini and python-tablet-driver.py into /usr/local/huion-linux-driver.

$ sudo mkdir /usr/local/huion-linux-driver
$ sudo cp config.ini /usr/local/huion-linux-driver
$ sudo cp python-table-driver.py /usr/local/huion-linux-driver
$ sudo cp TabletDriver /usr/local/huion-linux-driver

Create a symbolic link to the launcher file TabletDriver:

$ sudo ln -s /usr/local/huion-linux-driver/TabletDriver /usr/local/bin/TabletDriver

Then you can launch the driver:

$ sudo TableDriver

The console screen lists the configuration options and then displays the current active menu. You can change the active menu using the lower left button. This configuration creates 2 pointers: one for the mouse that you can keep on your primary screen and one for the tablet pencil that you use to draw on the tablet. The mouse can move on both screens: if you loose it, it could be on the tablet screen.
