Calibrate Huion Kamvas Pro 24 4K on Linux

About a year and a half ago I bought a Huion Kamvas Pro 24 4K as a replacement for an old Wacom Cintiq 21UX that died after being used over 10 years. Wacom no longer makes that model of display and their direct replacements cost over $2000, so I was hesitant to buy another. At some point, the algorithm must have noticed and recommended the Huion Kamvas. There are a few Kamvas models, but the top end one was about half the price of a comparable Cintiq from Wacom, and I managed to get it on sale.

I really like the Kamvas so far, but this issue keeps cropping up where the pen isn’t calibrated to the screen. I have two screens; one is the Huion Kamvas Pro 24 4K and the other is a Samsung 4K monitor. What happens is whenever I update to the latest version of Linux Mint, the calibration gets lost, and like I an idiot, I keep forgetting to write down the steps I took to fix it. By posting this, I’m sure I’ll be back to check the next time I upgrade my PC.


After a system update, the pen is no longer calibrated to the Huion display. On a system with two monitors, moving the pen from one edge of the Kamvas to the other drags the cursor from the edge of one screen to the opposite edge of the other screen.


In Linux Mint, open the Terminal program to get to the command line. Type xrandr. It should return something like

This output shows certain capabilities of the connected monitors, but all we really need to know is which one is the Huion. In this case, the Huion is using the HDMI port, and the system is referring to it as HDMI-A-0.

Next, type xinput into the command line. It should show something similar to the following:

(base) minty@freshness:~$ xinput

The Huion is mentioned in a bunch of different places, but the one we’re looking for the Huion Tablet_GT2401 Pen Pen. The system has given it the ID of 26, which we need for the next and final step.

On the command line, type in xinput map-to-output 26 HDMI-A-0, where 26 is the id of the Huion pen and HDMI-A-0 is the system’s reference for the Huion screen itself. After entering that, the pen is fixed. No reboot required.

In the past, I’ve installed Huion software for Linux and also installed Wacom drivers, which some people recommended as a fix. I’m not sure that’s necessary for this monitor model, since the Huion software was removed when the system was upgraded and I’m not sure the it was helpful even when it was installed. Also, since the Kamvas is made by Huion, I’m not sure the Wacom driver will work since they’re different companies. However, if the steps I mentioned don’t fix the issue, you’ll probably need to continue searching for other possible solutions, including installing the Huion software or installing Wacom drivers.
