It’s astounding to me that in Linux, in 2025, I can’t just simply output a custom resolution. You are probably typing a response right now with some xrandr nonsense and I PROMISE you, it won’t do it. I can’t even scale my screen within a normal resolution to make it fit within a boundary. But I can do this in windows with an nvidis gpu. Crazy

You don't have to use xrandr to create a custom framebuffer with scaling and/or centering, although it is capable of doing so. You can also use Gamescope (https://wiki.archlinux.org/title/Gamescope), which works on both X11 and Wayland, and with any GPU.

Traditionally it's used to launch a full-screen application, usually a game, but you can launch your window manager through it, if you want your desktop session to use a custom resolution with custom scaling and/or letterboxing.
