READ BEFORE YOU CREATE AN ISSUE: Arch package is broken
An arch package (not sure if official or AUR) is broken after an update. If you get this problem, just add your user to the video group.
Do not create new issues about this!
Official package switched from setuid to udev.
https://bugs.archlinux.org/task/63621
It's not so visible in the issue tracker link above, but Arch users need to add their system user to the video group (usermod -aG video <your-user>). Don't forget to log out of your desktop session for these changes to apply.
Thank you for creating this issue! Adding myself to the video group worked great!
As was already suggested on the Arch bug tracker, I added an install notice to the package as well, so hopefully nobody will have to go to this repo to find this ticket anymore 🙂
Hi everybody, I updated to the latest version of light but still not able to use it properly even after adding myself to the video group and logging out/logging in.
Any suggestion?
@xEnVrE I did have to restart instead of merely logging out/in.
Verify your user is in the video group with:
getent group | grep <username>
In case this helps anyone:
I had to add my user to the input group to be able to change the keyboard back light.
I got the https://github.com/haikarainen/light/releases/download/v1.2/light_1.2_amd64.deb version on linux mint.
adding my user to both input/video and restarting didn't do a thing. I have to sudo to change the light. Maybe a different group name for debian base?
I can confirm adding myself to the video group and restarting solved the issue for me on arch.
Hello, I added my user to the video group but it still won't change my brightness, I'm on manjaro kde
Can someone please mention this in the readme with the arch installation guide? It took my a lot of searching and then I landed on this issue 😅

Maybe we can just add "Arch users need to add their system user to the video group (usermod -aG video <your-user>)" so it is easier to find. This is also kind of tough to find 😅
It was already in the readme, but I added a clarifying statement under the Arch install section.
Back in the day you needed to have a lot of elbow grease to even install Arch, i.e., be able to read a readme file before opening/commenting on issues. Not sure if that's still the case as I haven't touched it in a few years now (primarily due to wiki mods/higher-up community members being complete degenerates). Hopefully the arch community can improve and get back to what it used to be, because it was a really good distro back in the day.
