For this, first you need to install xinput-calibrator (check in your package manager it may be named a bit differently, with – or _ in the middle…)

Now, you’ll need the name or ID of your device, so list devices with this command line:

xinput_calibrator --list | grep H610

Then I noticed the huion report two different devices with the same name, just different ID. So to find out which is the one corresponding to the actual stylus tablet area, get devices values with this command line:

xinput_calibrator --device 10

(adapt id number the the values you found on previous step…)

It will open a sort of calibration window, don’t click the crosses, just press any key to abort. Then you can see the default values of the device appeared in the console. One devices has much bigger max values (0 40000 0 25000), this is the one you should get the ID number. (in my case here was ID 10 )

Then calculate the values to set the active area to the same ratio as screen..
For example, for a 1920×1080 screen, I did this operation: 40000*1080/1920=22500

And finally set the calibration values (TopX BottomX TopY BottomY) like this:
xinput set-prop 10 “Evdev Axis Calibration” 0 40000 0 22500

xinput set-prop 10 --type=float "Coordinate Transformation Matrix" 0.5 0 0.5 0 1 0 0 0 1

xinput set-prop 10 --type=float "Coordinate Transformation Matrix" 0.5 0 0 0 1 0 0 0 1
