Hyprlandの人はArchかNixOSなのだろう。
おまいは駄目たと書かれるUbuntu。

Arch, NixOS and openSUSE Tumbleweed are very supported. For any other distro (not based on Arch/Nix/openSUSE) you might have varying amounts of success. However, since Hyprland is extremely bleeding-edge, distros like Pop!_OS, Ubuntu, etc. might have major issues running Hyprland.
