I thought if you write in the comment of your order to put Manjaro KDE they would do, I am not sure if they have started that or not.
Ok a quick search shows that it is only available for InfinityBook Laptops for now.
Lucky you, received your pulse 15 already while I had to wait for pulse14 hopefully should receive it within a week.
Aura and Pulse is similar just Ryzen 7 4700/4800U and 4700/4800H only difference is U and H version having a difference in power consumption.
sudo pacman -S tuxedo-keyboard will give you tuxedo keyboard pkg.
while
sudo pacman -S tuxedo-control-center will give you tuxedo control center app.
Once I receive the device I will look into all these tuxedo package and maybe update some for the Ryzen series laptops.
Thank you informing
