My huion tablet is not being detected on kinoite-nvidia (custom image)

General
1

As the title suggests, my graphics tablet (A Huion H640p) is not being detected. The tablet has worked without issues under regular Fedora and Ubuntu, but whenever I switch to Kinoite or Silverblue, it refuses to work.

Output of lsusb shows a device with a empty name

Is there any solution to this problem?

Hi, what is the output that you see when you run

sudo journalctl -f

and plug the tablet into the computer directly afterwards?

Note that the above command shows all events from the system. It is a good idea to use ctrl+c to stop journalctl a few seconds after you have plugged in the tablet.

I’m also curious: How does the tablet interact with the computer? Does it act as a storage device? Or as an additional screen? Or maybe both?

The tablet should act like an input device, buttons are getting recognized by KDE, the pen isn’t it seems.

The tablet was still plugged in when taking this screenshot

This also affects bluefin:latest and aurora:latest as of time of writing. I’m going to dig deeper into this on weekend

@amycatgirl
ok so Bazzite solves this by installing OpenTabletDriver using Arch distrobox, but I’ve went with Flatpak version since it’s a userspace driver.

Here’s the script which will installs it, disables built-in conflicting kernel modules, and launches a daemon. Unfortunately, it starts a GUI config util as well every launch due to flatpak not honoring no-UI arguments… but I can live with that.

#!/usr/bin/bash

flatpak install -y net.opentabletdriver.OpenTabletDriver

echo "blacklist wacom" | sudo tee /etc/modprobe.d/99-opentabletdriver.conf
echo "blacklist hid_uclogic" | sudo tee -a /etc/modprobe.d/99-opentabletdriver.conf    
sudo rmmod wacom hid_uclogic

mkdir -p ~/.config/systemd/user/

Thank you for this post, it has helped me get my tablet working, sort of. Krita isn’t recognizing the pressure I’m putting on the tip, however, the Open Tablet Driver Debug screen shows the pressure applied. That is with or without the tip set to the Left mouse button or None.

9

Well this is annoying, rebooted to see if that was needed to get pressure working in Krita and now it doesn’t detect the tablet

Oh by the way, running this in Bazzite.

10

I get the tablet recognized now after a reboot, but only if I run these commands from the script in the terminal

echo "blacklist wacom" | sudo tee /etc/modprobe.d/99-opentabletdriver.conf

echo "blacklist hid_uclogic" | sudo tee -a /etc/modprobe.d/99-opentabletdriver.conf    

sudo rmmod wacom hid_uclogic

systemctl --user daemon-reload && \
systemctl enable --user --now opentabletdriver.service

However, still can’t get Krita to recognize the pressure on the pen. This is still a good start.

11

Just finished polishing my patch for OpenTabletDriver flatpak (yet to be accepted). Here’s the command you need to run to disable kernel modules on Bazzite and other rpm-ostree-based spins:

rpm-ostree kargs --append=modprobe.blacklist=hid_uclogic --append=modprobe.blacklist=wacom

Then reboot using systemctl reboot

Part with echo "blacklist... won’t work here, I’ve forgot to update the script :blush:

Thank you so much, the detection issue is taken care of. Now to figure out why Krita doesn’t see the pen pressure. :grinning:

I’m still pretty new to the behind the scenes workings of an imutable distro.

13

Meanwhile The GIMP mostly works with speed and pressure. That’s all the advanced stuff this tablet can do

14

Awesome, glad to help! I’ve checked if pressure worked in my Krita, and it turned out it didn’t :sweat_smile:
I’ve launched the OpenTabletDriver GUI and selected “Artist Mode” in the bottom left:
image

Now my Krita “feels” the pressure, check if it works for you :wink:

15

I can only get Krita to draw in Absolute or Relative Modes. Artist Mode doesn’t seem to work. The Tablet Tester in Krita shows output from the pen in all three modes, but not showing pressure. I can manage without pressure control in Krita but a bunch of my custom brushes are better with pressure. Meanwhile The GIMP seems to work with pressure, but it’s super sensitive and opacity maxes out fast, but for some reason I can’t edit the pressure curves in GIMP. Pressure worked fine everywhere in Linux Mint, but took a lot of pressure to work properly.

All said, at least it is recognized now. Thank you again.

Considering this tablet is an old Windows XP Tablet, this is great.

Well after some fiddling and an update to the driver, I’m now getting pressure working in Krita. I’ve done some adjustments to settings and things are working better. The painting doesn’t work consistently due to some funny thing (maybe a Krita issue) where there is a circle around the brush preview and the cursor doesn’t easily move from centre. It will only draw if the cursor can move out to the circle edge, if it doesn’t move to the edge it just moves the cursor around.

Screenshot_20240810_230305

Edit:
Found Tool Options has a “Brush Smoothing” Weighted or Basic seem to work best, “Stabilizer” was unreliable.

Edit 2:
My trouble in Krita may actually be the pen for my tablet, it is an old tablet after all.

Thank you again, this has been a big help.
