If your AMD card is older than your latest linux distro release it’s plug and play, no driver installation required
Wayland works pretty well on most desktop environments too

beware fresh released AMD cards in combination with long term release distros like Debian stable, you most likely will need the driver from the AMD website (not recommended)

Arch Linux (like some other distros) also has a security tracker: https://security.archlinux.org/

the init command probably only works in Debian nowadays givin it’s a thing from the sysvinit era

Latte Dock users will need to say goodbye then

you probably have old hardware in that case
the latest kernel releases greatly helped with the effiency of newer AMD and Intel (Hybrid) CPUs which can give you a longer battery usage on laptops
