This page is about the Laptop ROG Strix AMD laptop. Runs pretty good out of the box, with some minor issues.
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
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;
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"
Then adding the user to the
input group. (Default udev rules override for kbd_backlight, so you can't set them to video as well) AUR is a nice script that can increase and decrease brightness, which can be bound to the media keys.
Fans don't have OS control, and handled by ACPI. Upshot is works out of the box, downside is can't configure them.
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.
Fans turn 100% and computer becomes unresponsive after long idle time
Haven't found a fix for this, but reporting this issue nontheless.
Bluetooth device not found
A patch has been applied for the bluetooth controller, that will prob roll in the 4.18 kernel. See this forum thread; https://bbs.archlinux.org/viewtopic.php?id=234603
