Are you in input group? This requires input group privileges. Or you could just run with sudo.

Still, I am not sure why you got this particular error.

Though I never intended for anyone else to use this. But If people are noticing this project I might as well clean it up and add a README.

Are you in input group?

$ getent group | grep input input:x:107:user

I'd wish to have a screenshot

How the app looks

Gimme 5 minutes. Though its pretty barebones.

Nice. What python version do you use?

[codelif]

3.11.7

I think I got it. The encoding parameter was added in 3.11 for the getoutput function.

I think Ubuntu 22.04 ships with 3.10, so maybe that's the problem. I think a temporary fix would be to just remove that encoding parameter.

I added that because many devices have Chinese characters in their names, so applying a utf-8 encoding would prevent an error.

I didn't know, this was a recently added feature, I try keep my scripts backward compatible. :p

[codelif]

Could you check the output of the command libinput list-devices?

[faveoled]

Wasn't installed. Installed and now app works fine :+1:

Thanks for trying out. It was really insightful for me.
