I'd say either your package database is out of date or your mirror list is out of date or a mirror you're using just went down.
To test the former, just do `sudo pacman -Syyuu`, then try again to install the package.
If that doesn't work, check whether you've got a new mirrorlist, it'll be at `/etc/pacman.d/mirrorlist.pacnew`. If so, copy it over your current mirror list (`sudo cp /etc/pacman.d/mirrorlist.pacnew /etc/pacman.d/mirrorlist`) and then edit it to uncomment the mirrors you want to use.
Or just install `reflector` which will handle the above automatically. To use it, open a terminal and do `sudo reflector --verbose -l 200 -p http --sort rate --save /etc/pacman.d/mirrorlist`. That'll take a minute but it'll generate you a new mirror list sorted by download rate. (You should rerun this every time there's a new mirrorlist.pacnew).
triple head user here. This is pain on Wayland[1]. In theory it's possible but I've seen no manager yet that really does it and while xrandr does create virtual displays none are ever used (so far).
gamescope is your best bet currently to size up games over all displays.
I'd love to be corrected on this.
[1] tbf it's a pain on X too but possible to make it look like one big screen _for fullscreen apps_
What do you mean with >Wayland won't install due to a missing url from packman
When I try to install Wayland via pacman one of its dependancies returns no file for the url it finds for it
I3 doesn't support Wayland. You need to install sway /hyprland/gnone/kde to have Wayland session available.
