/sys/class/leds/asus::screenpad/brightness exists, but writing to it has no effect. Occurs on 5.18.12 and 5.18.10. The /lib/modules/5.18.{10,12}/extra folders are empty, which is odd...

The modules are also zst-compressed, could that be an issue?

Thanks in advance for any support you can offer.

I switched to the fallback initramfs image on 5.18.12 and rebooted a few times -- that seemed to work. Don't know what the actual fix is.

Did the acpi_call-dkms method work?

To try it run:

sudo pacman -Syu linux518-headers
pamac install acpi_call-dkms
echo '\_SB.ATKD.WMNB 0x0 0x53564544 b32000500FF000000' | sudo tee /proc/acpi/call

That sets the brightness to 0xFF
