In case someone doesn’t know it yet:
If you update your Arch Linux system with a kernel upgrade, the kernel modules will NOT be loaded again automatically by default and things like FUSE (used in AppImages for example or other FUSE based mounts) will not work without intervention
simple rebooting is the foolproof way or setting up kernel module reload hooks: https://archlinux.org/packages/extra/any/kernel-modules-hook/
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)
