But I wonder if I can install an LTS kernel in an already existing installation as a fallback?
Yes, that's not very hard and a good idea.
The wiki sounds fairly straight forward, but I get lost where it says "install kernel" without saying how, and to "edit the grub config file" without an explanation, and to "generate the main configuration file".
Not sure whether I am getting in way over my head or if it is actually quite simple. That's what I need to know.
If you use kernel modules that are not part of the stock kernel (like nvidia , catalyst, vhba-modules ) additonal steps are needed.
For now i'll assume you don't have such modules.
- Almost every time an arch wiki page states "install program" , it means one of 2 things : install with pacman install from AUR with makepkg
The lts kernel is in official repos, so you can install it with pacman.
- to be able to boot the lts-kernel , you have to add an entry to your bootloader config for it. Grub stores that info in grub.cfg , grub page lists where it can be found.
As Root : copy grub.cfg to something like grub.cfg.original open the file with your fav tekst editor. Copy the entry for arch stock kernel to a new entry and change what is needed to have that boot the lts-kernel instead of the stock kernel.
Reboot and test if it works.
