"Does not work" is not a problem description…

lspci
ls -R /sys/class/backlight

And your xorg log, please. https://wiki.archlinux.org/title/Xorg#General

=> ix.io won't require anyone to download anything.

cat /sys/class/backlight/acpi_video0/*brightness*

The xorg log is from a terminated server and uses the modesetting driver?
Is the /sys/class/backlight/acpi_video0/ stuff from a boot using the nvidia driver or nouveau?
