games-action/prismlauncher depends on xrandr because version of minecraft that use Java 8 use LWJGL which crashes when xrandr isnt installed because it uses it to get screen resolutions proof: is the only answer on stackoverflows URL: /58939641/lwjgl-crashing-at-startup
Xrandr is already mentioned as an optional dependency in the post-install phase. It is only required for minecraft versions <=1.12.2 and as such should not be a hard requirement.
