Title: Light does not work without sudo
Post by: Artt on 23 August 2023, 13:20:42

Hello everyone,
I do not know why when I run the light command as

light -S 50

it does not work.

Here is my user id:

Code: [Select]

user@host ~ $ id user
uid=1000(user) gid=1000(user) groups=1000(user),998(wheel),996(audio),987(storage),985(video)

When I do it with sudo privleges it works. Do you know what might be the cause?

Yes user is my account and it is in the video group.

Can you recommend another program for controlling screen backlight from command line?

look at wiki (https://wiki.archlinux.org/title/Backlight#Backlight_utilities)
I recommend "xorg-xbacklight". if it does not work then "acpilight"
if you want a lot of useless functionality "clight"

Hello,

I just use acpilight to adjust the brightness.

I created four icons in a panel that automatically retracts:
