sowm VS hello-wayland

To add to the comment above, if memory is all you care about, I managed to get it down to 75MB once with custom kernel and sowm.

You can check https://github.com/dylanaraps/sowm It will be handy to you to understand how Dwm works

Or sowm.

I managed to get 75mb with X session on Void. (sowm + minimal kernel)

Then perhaps you should have a look at sowm. It is a fork (if you can still call it that) of dwm that has no tiling support and no bar.

If you are r/linux4noobs then you probably won't be able to get it running but... I managed to get voidlinux with sowm and a custom kernel to 70MB memory usage.

This is a great article and I remember reading it numerous times while I was implementing my own window manager.

For someone interested in working on a really fun and rewarding hobby project a WM is a great one to look into since there are so many resources starting from really small implementations:

- https://github.com/mackstann/tinywm

- https://github.com/venam/2bwm

- https://github.com/dylanaraps/sowm

- https://github.com/dcat/swm

- https://github.com/JLErvin/berry

Which are great at introducing the concepts and allowing you to grok the required libraries.

There are also a bunch of more full featured window managers which will introduce you to more advanced topics:

- https://github.com/baskerville/bspwm

- https://github.com/herbstluftwm/herbstluftwm

- https://www.nongnu.org/ratpoison/

- https://github.com/conformal/spectrwm

Gradually as you get more familiar with the ecosystem a few questions will come up:

Should I use X11 or XCB? - I personally used XCB and didn't find it too difficult to interface with, and there are a large number of implementations which use it (2bwm, bspwm, ratpoison, etc) so you shouldn't have an issue with learning more about it. But the documentation is pretty limited. If you are just wanting to write a toy WM than X11 is perfectly fine.

X or Wayland? - If you're wanting to write your first WM as a hobby project than I would recommend X over wayland just due to the much larger amount of reference material and documentation. You will have a much easier time getting your feet wet. Ignore the comments about X dying as it doesn't really matter for a hobby project, since the whole point is to have fun.

Feel free to check out my window manager which is an example of what just reading this blog post and getting inspired can result in: https://github.com/cfrank/natwm

I first saw the trick at https://github.com/emersion/hello-wayland

hello-wayland and tinywl are simple wayland client and server respectively. Also wayland-book

You think this is bad? Just look at a native Wayland "Hello World" client [1]. This doesn't even print hello world. You have to do the text rendering yourself. And you need at least 500 more lines to implement the equivalent to a simple XGetImage() call.
