ktrl doesn't work on Gnome

[sabitm]

I'm using ktrl installed from crates.io and trying to test it using example configuration based on steps from README, but it doesn't work. When i press any key from my keyboard, it doesn't appear in my monitor. It's like the keyboard just unplugged until i stopped the systemd service and then it worked again. This is my setup

OS: Arch Linux x86_64
Kernel: 5.10.19-1-lts
DE: GNOME 3.38.3 (Wayland)
WM: Mutter

It doesn't output any error in program log. But here some error related to ktrl from journalctl:

kernel: input: ktrl as /devices/virtual/input/input41
systemd-logind[1554]: Watching system buttons on /dev/input/event18 (ktrl)
gnome-shell[2630]: Could not open device /dev/input/event18: GDBus.Error:System.Error.ENODEV: No such device

Hello Sabit!

Are you running ktrl as a systemd service?
Regardless, I'd advise checking two things -

1. The user you're running ktrl with has sufficient permissions (root / a 'ktrl' owned user you've created)
2. You've located and provided the path to the correct input device :)

Yes, i'm running ktrl as systemd service based on README

1. I created a new user named 'ktrl' as instructed on the README, that have this permission

$ groups ktrl
audio input uinput ktrl

and when i run it as systemd service, it has the right owner

$ ps aux | grep -i ktrl
ktrl       34048  0.0  0.0   3972  2300 ?        Ss   21:00   0:00 /usr/local/bin/ktrl -d /dev/input/by-path/pci-0000:00:14.0-usb-0:2.2:1.0-event-kbd

2. I test my keyboard in /dev/input/by-path using cat. And it's outputting something when i press the key on my keyboard. So, i think it's not the problem

Ah! In that case, I probably messed up somewhere haha.
Unfortunately, I'm currently preoccupied with other obligations so I'm not sure when I'll be able to investigate this.

So, if you're up to it, I'd really appreciate your help here.
I always welcome PRs and would love any assistance with this issue.

I'm having the same issue, setup information below.

I've setup everything as per the README (custom ktrl user, all files in /opt/ktrl, running via systemd service). However, I'm not seeing any issues in journalctl output like @sabitm is.
