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 xorg-xbacklight will not work; since Radeon cards don't support RandR. The relevant module for backlight is `amdgpu_bl0`. (Keyboard LED's are interfaced with `asus::kbd_backlight`) light works well, and available in the repos. (The default should be the screen backlight) For example; the following commands will increase/decrease backlight of the screen;

    $ light -A 5
    $ light -U i

For controlling the keyboard LEDS using the same command; the target must be defined;

    $ light -Ars "sysfs/leds/asus::kbd_backlight" 1
    $ light -Urs "sysfs/leds/asus::kbd_backlight" 1

## Fans

lm_sensors do not detect any interfaces for fan control. However, fan control through NBFC works well; and there is a profile for this laptop. Enabling and starting the service files, and applying the configurations are sufficient.

## Troubleshooting

### Secure Boot

The BIOS has an utility to load your own BIOS keys; however loading my own keys in the BIOS using the firmware interface did not work.

### Fans turn 100% and computer becomes unresponsive after long idle time

Haven't found a fix for this, but reporting this issue nonetheless.

### Crashes with MCE

The system will sometimes crash (check the Phoronix thread). The problem seems to be the AMD processor. There is no suggested fix other than RMA; you can check if you are affected by running ryzen kill script. My personal experience is that I have two cores that cause these errors; and I had not have it happen much after configuring fans using `nbfc`.

### Bluetooth and network issues

The wifi card is of model `rtl8822be`. Older kernel versions don't have the bluetooth module for this card (>4.19). Also, on 5.2; the rtl cards wifi modules were merged into `rtlwifi`; which was not working for a while. (See my BBS thread here) Currently, wifi works with the stable kernel; but is noticeably slower than the previous kernel module.
