I have the same issue which is described here, but for a Huion h640p tablet instead of the wacom one:
Only half of Wacom Intuos tablet area maps to entire screen horizontally
The width x height of my tablet is 65534 x 32767.
But xsetwacom --get "<tablet ID> Area shows 32767 x 32767, and only the left half of the tablet is mapped to the whole of my screen. The problem persists with external monitor connected and removed.
I tried resetting the area forcibly using ResetArea to what it should be, and half of the tablet was mapped to half of my screen; the right half the tablet and the screen were inaccessible.
My system configuration is:
- Operating System: Kubuntu 20.04
- KDE Plasma Version: 5.18.5
- KDE Frameworks Version: 5.68.0
- Qt Version: 5.12.8
- Kernel Version: 5.11.0-41-generic
- OS Type: 64-bit
The tablet was working fine before I made the following updates through Discover:
