FreeBSD how to change backlight in a user friendly way?

[kriptomahsun]

sudo backlight 100
This works, but this is just weird isn't it? Why sudo for just changing backlight?

As I pointed out in your other Thread 97017, if a normal user is in the "video" group, this user doesn't need special permission to access backlight(8).

% ls -l /dev/backlight/*
lrwxr-xr-x  1 root wheel    23 Mar  3 11:01 /dev/backlight/amdgpu_bl00 -> ../backlight/backlight0
crw-rw----  1 root video 0x19f Mar  3 11:01 /dev/backlight/backlight0

Note bold highlighted line, showing "video" group read-write access to backlight0.


You stated your machines brand and model as Dell Inspiron 15 7559, have you tried to load acpi_video(4) to get the brightness function keys working?
