@Terence64w I also have an Aura 15. Just install the flavour of Manjaro you want (I have XFCE) and then install tuxedo-keyboard (this will enable the Fn keys shortcuts) and tuxedo-control-center (this one is used to control fan/cpu speeds). That’s it more or less - you have to use kernel 5.10 though (I tried 5.4 but I get a black screen on boot).

Note that the tuxedo packages are now updated and do work on the Aura.
