Wacom Problem - Fedora35

omennia · November 19, 2021, 2:28pm

Hello, I have a wacom tablet that I use mostly to take notes, that has touch capabilities (it works like a touchpad).
For some reason when the tablet is plugged in everything works fine, but when I connect it by bluetooth the writing / drawing gets really awkward.
In other words, when the tablet is plugged in, it seems that the touch function is disabled as long as the pen is near the tablet. And when on bluetooth, it just goes berserk.

Also, I tried to recreate this problem with Ubuntu and I could not.
I am really considering moving to Ubuntu because of my classes
So I am trying to understand if there is a way to fix this, as I love fedora more than Ubuntu

Thanks all

Did you give a try to search about Bluetooth? We do also have some cases about this wacom tablets, did you search about it?

Did you try with an older kernel?

If you have some more questions here, we would definitely need more info about hour hardware:

inxi -Fzx in terminal and post the output as </> Preformatted text here.

Thanks for your answer.
I tried to search as much as possible, and even posted a query in the libwacom page, altough no one has answered yet. About kernel versions, I am not so sure, but I can guarantee this was not working on fedora 34 (and I think kernel version has changed since - I am still a noobie in what concerns these topics).

I have tried to reproduce the problem in Ubuntu and Mint, and both are working fine. So I thought it could possibly be Fedora related? When plugged in it works fine too.

Here is the output of inxi -Fzx

What is the Wacoms exact model ?

omennia · November 21, 2021, 1:19pm

It’s a Wacom Intuos Pro medium model PTH-660.

Hugo

Since your config says you’re using X (and not Wayland), you can use the command xsetwacom to set the wacom tablet options. Use

man xsetwacom

to see what you can do.

Note that options you set via xsetwacom are not persistent. If you find an option that solves the problem and want to make it permanent, you need to make a config file and put it in /etc/X11/xorg.conf.d

If the going beserk you describe only occurs when you try to use the tablet, it could be that touch is not deactivated properly when using the tablet via bluetooth. If you don’t care about touch (and since you use it for notetaking, I assume you don’t), you can try

xsetwacom list devices

to get the device-name of your tablet, then

xsetwacom [device-name] set Touch off

You can try other options using xsetwacom if that doesn’t work.

However, since it works under Ubuntu, it’s almost certainly a kernel issue. Check out

https://discussion.fedoraproject.org/t/installing-an-5-10-lts-kernel-in-fedora-35/18133

for how to install an old LTS kernel on Fedora. (Note kwizart is a Fedora maintainer so his COPR should be trustworthy.)

Hey Jonathan, thanks for your detailed reply.
I have checked the manual, and compared the output of each device when connected by bluetooth and by usb, with the command xsetwacom get "device id" all.
When connected by bluetooth a fourth device appears with the name cursor. I will check ubuntu to try to determine if the issue comes from this “device”. For the other three devices, the output is exactly the same when connected by bluetooth and usb.

Unfortunately what I really wanted was for the touch to work without having to carry too much stuff around. Even if I take the cable, whenever I have to move the laptop I have to take the tablet with me. It shouldn’t be a must.

I’ll be sure to check the lts kernel.

Thanks for your kind answer, all the best!
