Please understand that I haven’t tried or installed Arch Linux yet. From what I understand by reading and watching related videos, Arch is often breaks and a lot of time is required to fix issues. But I have also read comments from arch users who claim that arch has only crashed or caused them problems only a couple of times in a year.
Wouldn’t a stable or non rolling release distro be a great choice for the Steam Deck?? Also, how frequently do the packages get updated on steam os?
Manjaro isn’t great, but for a new Linux user, who doesn’t tinker, it’s quite reliable. Manjaro avoided the Grub crash earlier this year which every other Arch-based distro failed to boot from.
My recommendation is Endeavour, but having the Pamac Manjaro GUI makes things a lot less daunting for those trying Linux for the first time.
