This page is about the Laptop ROG Strix AMD laptop. Runs pretty good out of the box, with some minor issues.

Backlight

This ASUS model comes with Radeon RX580. Backlight with xbacklight will not work; since Radeon cards don't support RandR. The relevant module seems to be amdgpu_bl0, and asus::kbd_backlight for the keyboard backlight.

You need to set the permissions for the /sys/class/backlight/amdgpu_bl0/brightness and the keyboard version, as they are only editable by root. The page Keyboard backlight suggests a systemd unit or a dbus daemon (that doesn't compile). You can write a DBus daemon yourself, or change permissions some other way. I suggest the following udev rule;

/etc/udev/rules.d/backlight.rules
ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="amdgpu_bl0", RUN+="/bin/chgrp video /sys/class/backlight/%k/brightness"
ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="amdgpu_bl0", RUN+="/bin/chmod g+w /sys/class/backlight/%k/brightness"
ACTION=="add", SUBSYSTEM=="leds", KERNEL=="asus::kbd_backlight", RUN+="/bin/chgrp video /sys/class/leds/%k/brightness"
ACTION=="add", SUBSYSTEM=="leds", KERNEL=="asus::kbd_backlight", RUN+="/bin/chmod g+w /sys/class/leds/%k/brightness"

Then adding the user to the video group. brightnessctlAUR is a nice script that can increase and decrease brightness, which can be bound to the media keys.

Fans

Fans don't have OS control, and handled by ACPI. Upshot is works out of the box, downside is can't configure them.

Troubleshooting

Secure Boot

The BIOS has an utility to load your own BIOS keys, which was glitching for my FAT32 formatted USB drive. Tried using keytool, which bricked the computer. I suggest further work into this.
