Tiny Core Linux: a 23 MB Linux distro with graphical desktop

Not to disrespect this, but it used to be entirely normal to have a GUI environment on a machine with 2MB of RAM and a 40MB disk.

Or 128K of ram and 400 kb disk for that matter.

A single 1920x1080 framebuffer (which is a low resolution monitor in 2025 IMO) is 2MB. Add any compositing into the mix for multi window displays and it literally doesn’t fit in memory.

Do you really need the framebuffer in RAM? Wouldn't that be entirely in the GPU RAM?

To put it in GPU RAM, you need GPU drivers.

For example, NVIDIA GPU drivers are typically around 800M-1.5G.

That math actually goes wildly in the opposite direction for an optimization argument.

They also pack in a lot of game-specific optimizations for whatever reason. Could likely be a lot smaller without those.

Even the open source drivers without those hacks are massive. Each type of card has its own almost 100MB of firmware that runs on the card on Nvidia.
