Install Huion Kamvas 13 graphics tablet on Ubuntu¶

Sunday, September 13, 2026

I’m still trying to get our new Huion Kamvas 13 graphics tablet to work on Ubuntu 26.04. More precisely the model is named GS 1331.

The opentabletdriver is installed, but the pencil isn’t detected at all (it doesn’t cause a mouse cursor to appear). I followed the instructions in https://opentabletdriver.net/Wiki/FAQ/General, and lsusb sees and reports it the tablet:

Bus 001 Device 011: ID 256c:006d HUION Huion Tablet_GS1331

The name “Tablet_GS1331” is indeed not in the list of supported tablets.

Gemini told me this:

Since OpenTabletDriver works entirely in user-space, it relies on explicit layout files (.json) for every specific device revision. Your HUION Kamvas 13 (GS1331) under the 256c:006d identifier is a known variant. Support for it was officially tracked and added in OpenTabletDriver Pull Request #3178, but depending on your exact version package on Ubuntu 26, it may not be natively bundled yet. [1] (https://github.com/OpenTabletDriver/OpenTabletDriver/issues/3447), [2] (https://support.huion.com/en/support/solutions/articles/44001769972-does-huion-have-a-tablet-driver-that-supports-linux-), [3] (https://github.com/OpenTabletDriver/OpenTabletDriver/releases)

You can get your pen working immediately by manually dropping the device configuration file into your local path and ensuring conflicting kernel modules are cleared.

(Followed by instructions)

mkdir -p ~/.local/share/OpenTabletDriver/Configurations
nano ~/.local/share/OpenTabletDriver/Configurations/Huion_GS1331.json

And then pasted the suggested JSON suggested by Gemini (taken from some thread on GitHub) into the file:

{
  "Name": "Huion Kamvas 13 (GS1331)",
  "SupportedIdentifiers": [
    {
      "VendorID": 9580,
      "ProductID": 109
    }
  ],
  "Digitizer": {
    "Width": 293.76,
    "Height": 165.24,
    "MaxX": 58752,
    "MaxY": 33048
  },
  "Pen": {
    "MaxPressure": 8191,
    "Buttons": {
      "ButtonCount": 2
    }
  },
  "ReportParser": "OpenTabletDriver.Configurations.Parsers.UCLogic.UCLogicTiltReportParser"
}

I also added two lines to my /etc/modprobe.d/blacklist.conf file as suggested by Gemini:

blacklist hid_uclogic
blacklist wacom

Though this might be complete nonsense in my case. TODO: remove them later and test whether it works without them.

I then discovered that actually my otd-daemon service fails to load. “sudo journalctl -t otd-daemon” reports:

sept  13 21:55:53 ding otd-daemon[334263]: Failed to resolve libhostfxr.so [not found]. Error code: 0x80008083

I have installed two versions of .NET: dotnet-runtime-10.0, which is part of the Ubuntu 26.04 distribution, and dotnet-runtime-8.0, which I installed manually as instructed in the Microsoft documentation, because “apt install opentabletdriver” failed when only version 10 was installed. It reported no errors when version 8 was installed as well.

After reading this I thought okay, it’s trying to use the default version (10), let’s set DOTNET_ROOT so that it finds the old version.

Indeed I have the following:

$ cat /etc/dotnet/install_location
/usr/lib/dotnet

I said “locate dotnet” to find out that I have a directory /usr/share/dotnet/shared/Microsoft.NETCore.App/8.0.31, which seems to be the root directory of the version 8 because it contains a lot of files.

I then (after reading this) said “sudo nano /usr/lib/systemd/user/opentabletdriver.service” and added the following line in the [Service] section:

Environment="DOTNET_ROOT=/usr/share/dotnet"

Now the driver loads, and the pencil works! But the mouse pointer is about 4 cm to the right of where it should be. And it doesn’t click. Seems that it needs calibration or something.

I need to open the OTD GUI. Usually this would go using:

otd-gui

But because OTD requires the old .NET version, I must use the same trick as with the driver:

DOTNET_ROOT=/usr/share/dotnet otd-gui

Gemini tells me:

If the cursor moves but tapping the pen on the glass doesn’t left-click, OpenTabletDriver isn’t passing the pressure threshold as a digital click event to Linux. [1] (https://opentabletdriver.net/Wiki/FAQ/Linux)

In the OTD GUI, click on the Pen Settings tab. Look at the Tip Binding configuration. Click the … (Advanced Binding Editor) next to Tip.

These instructions don’t work exactly as is, but today I’m too tired to play with such things. That’s for tomorrow.
