Description:
### Is this a new report?

Yes

### System Info

Void 6.5.12_1 x86_64 GenuineIntel uptodate rFFFFFFFFF

### Package(s) Affected

gnome-44.0_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

_No response_

### Expected behaviour

1. Using the slider for changing the brightness, should work.
2. Using the keys for changing the brightness, should work.

### Actual behaviour

Neither the slider nor the keys work for changing backlight.

Using `light -S 10` works for me.

I tried this solution but it didn't work: https://askubuntu.com/a/1402769

### Steps to reproduce

1. Start gnome session from gdm.
2. Try to change backlight.
