How to Config Graphic Tablet

[Team Fortress 3]

The graphic tablet config (wacom) is missing by default in the Input Devices menu. Here's how to bring it back.

Open a terminal window ctrl+alt+T, then type:

sudo steamos-readonly disable
sudo pacman-key --init
sudo pacman-key --populate archlinux
sudo pacman -S kcm-wacomtablet
sudo steamos-readonly enable

Cool. Cool. You need to set your `sudo steamos-readonly enable` back.
Note: This will likely break with Steam OS updates.

It might be possible to do the same without using distrobox/podman OR a VM ... if you can enable USB pass through.

Thanks for the tip retrogunner, I'll edit my post to include sudo steamos-readonly enable.

Hello, when running the "sudo pacman -S kcm-wacomtablet" line, I get the following error,

error: xf86-input-wacom: signature from "GitLab CI Package Builder <[e-mail]>" is unknown trust

Do you want to delete it? [Y/n] 

Is there anyway around this?

Ive had to reinstall the tablet settings many times at this point, rather frustrating that the deck supports graphics tablets but not the ability to modify them with simple settings.

For this time round i've been getting this error and it seems to be an issue with signature verification.

you can change a few settings in rootfs/etc pacman conf
which disables it and worked for me.
check pacman conf for these 3 settings and change them to this.
SigLevel = Never
#LocalFileSigLevel = Optional
#RemoteFileSigLevel = Required

This being said i'm still not sure on the ramifications of doing this, i'm still quite new to linux and it seems like trying to modify the deck even slightly is trouble and a half even for linux users, I believe it's just a way to determine if your package is legit, but i'm not 100% so be careful with this.

Can you use the tablet as an input method? Like using it as a mouse?

Thank you!

After I changed SigLevel to equal 'Never', I was able to follow the remaining steps posted by OP without any errors.

After a reboot I was able to see the graphics tablet input settings and it was able to detect my wacom tablet.

I then changed SigLevel back to its original setting and everything is still working as it should.
