Summary

An informative summary from a physical point of view: https://www.youtube.com/watch?v=wsu-VsnALS8

Adjusting BIOS

You'll need to:

  • Add an admin password.
  • Disable secure boot (I forget if I actually tested if this was necessary, it might not be).
  • Change the hard drives from SATA to AHCI (or else they won't be recognized when running fdisk/gdisk).
  • Disable 'Trusted Computing', this got rid of a temporary hang on start up that mentions IRQ being disabled.

Kernel Parameters

  • No additional kernel parameters required, adding i915.enable_guc=2 will have a negative effect on performance.

Xorg.conf

For the Intel GPU, under the Device section:

  • Set TearFree to "true"

Fan Control

Fans are controlled by the BIOS in this model. At first, you might think the fans aren't turning on - and this might actually be the case, as it was for me. They should turn on when you enter the BIOS. If the BIOS doesn't show the fan spinning above 0 RPM after a few minutes, then your fans probably aren't working after the install. It will take a high temperature to turn them on, > 80C for the CPU sensors.

To fix fans not working after install:

cd /sys/devices/platform/asus-nb-wmi/hwmon/hwmon#/
su #(enter root password)
echo 0 > pwm1_enable #the fan should turn on to ~7000+ RPM
reboot

Enter bios upon reboot, and the BIOS should be able to regain control of the fans, and it will work for your install as well. The fans will persist at ~max speed on reboot, but without entering the BIOS it won't regain control of them.

Extra

Be sure to install linux-firmware or the wifi-card won't be recognized once you leave a live boot.
