Setting Up GT-156HD V2 Huion Tablet on Ubuntu
Hi there, so you bought a GT-156HD V2 Huion tablet as well?
Well, it is great that there are ready-made drivers which Huion already made available for Windows. However, what if you are using a Linux operating system like Ubuntu?
This is a step-by-step guide on how to install the appropriate linux drivers required to start using GT-156HD V2 tablet on Ubuntu. Note that there are no official drivers specifically made for this tablet model.
Steps:
2. Run $ sudo dpkg -i name_of_debian_file.deb. (This installs the Digimend Linux Drivers)
3. Connect your tablet properly and it should be ready for use.
Encountering Issues
If you have a multi-monitor setup, you might find that, after installing the drivers, the cursor does not follow exactly when your tablet pen goes, resulting in an inaccurate offset.
If this happens (like it did for me), this could be because your drivers has mapped the entire layout of your multi-monitor setup. Take note that the default monitor setting for Digimend drivers are of a single monitor setup.
To fix this, simply go to the linuxwacom's github page on Dual and Multi Monitor Setup. Depending on what kind of multi-monitor setup you have, simply follow the instructions provided on the page to configure the proper mapping settings for your tablet pen. Here is a reference guide on how to use their instructions to restrict your stylus to just one monitor and rectify the offset.
Steps:
1. Identify the number of monitor you are using in your setup and their individual resolution.
Number of Monitors: Use your eyes.
Monitor Resolution: Open Displays in your Ubuntu task bar menu. There, you should be able to see each monitors' respective resolution and modify them to your needs.
[My setup was a Dual Monitor with same resolution.]
2. Identify the name of your tablet pen by running the following command:
$ xinput
[This should be bring up a list of connected devices. The tablet pen device should be labelled intuitively.]
[My tablet pen was "Tablet Monitor Pen".]
3. Depending on which monitor is your tablet monitor, you can restrict the mapping of the stylus to the one you want.
For my case, it was the right monitor. So I followed the instruction provided on the page mentioned earlier and used the following command.
$ xinput set-prop "Tablet Monitor Pen" --type=float "Coordinate Transformation Matrix" 0.5 0 0.5 0 1 0 0 0 1
4. The cursor offset should be fixed at this step and the cursor should follow exactly where your stylus is.
Thank you. If you found this guide helpful, be sure to follow me on Instagram or Facebook. If you have any issues, do leave a comment and I will see how I can help.
Cautionary Note: As far as I know, there are no official linux support for non-wacom graphic tablet devices which are currently properly maintained. Digimend, despite being used in the guide, does not support this exact tablet model and their development has been discontinued for any newer models, as evinced by multiple github repositories housing workarounds (eg. benthor's GT191 Linux Drivers Workaround).
