Hi, there, I have Huion Kamvas 13 (2020) which I'm using with my Gentoo systems.
I've tried to find as much information however getting hardware working isn't well documented.
For my setups using Plasma Wayland, I have done the following:
- | Code: | | CONFIG_HID_UCLOGIC=y |
as per: https://forums.gentoo.org/viewtopic-p-8774940.html#8774940
- | Code: | | # emerge -av dev-libs/libwacom |
- libwacom isn't just for Wacom devices, the name is historical and now it includes multiple other devices: https://github.com/linuxwacom/libwacom
Observations:
- Krita is handling the pressure sensitivity well
- Plasma's Drawing Tablet section picks it up and you can adjust the mapping of where the stylus output will be placed
- OpenTabletDriver is interfering with libwacom -> the tablet won't work if both are present
- I am unable to directly assign the tablet keys as shortcuts to Krita -> I have to pass through KDE's drawing tablet (libwacom) settings and assign to the same keys
I'm not certain about which kernel flags are required - any pointers on how to do so are welcome!
Other:
- At one point the tablet couldn't be recognized and I had to restart before it was picked up as expected again. I'm not sure what caused the problem and can't replicate for now.
Hope that helps for other people who have the same or similar enough drawing tablet. |

I think I found how it got to this state.
I disconnected the tablet and attempted to reconnect.
The display part was picked up correctly.
The drawing tablet part wasn't picked up when reconnecting. Will try to find what needs to be restarted.
PS:
As I am using the USB-C port on my RX6800, I'm not sure if I should be looking there as well. |

Thanks for the info! I've seen the digimend driver and used it at one point.
Took me awhile to get back to it however the problem is indeed the USB-C port on my reference RX6800.
For whatever reason, it's not keen to provide data when hot plugging. I observe the same odd behaviour when connecting to something else as well - my Android devices aren't picked up by adb after reconnecting.
iirc AMD marked the port for use with VR headset only after the release or something of the like.
Using the hydra cable with HDMI && 2 USB A ports is consistent and the Huion is picked up as expected every time.
On my Ryzen ThinkPad using the same setup with libwacom, reconnecting works great when using the USB-C port.
Overall, for me, using libwacom is more than enough - it doesn't need maintenance or setting up the digimend drivers. |
