Wayland is a modern display server protocol that will eventually replace X11. It is still not quite a hundred percent there, but it has been improving steadily and gaining ground over the past years. It is expected to become the new default display server on Linux systems at some point in the near future… Whatever near means in that context.

This past weekend I had some time to play around with Sway, a window manager and Wayland compositor that mimics i3. How did it go?

My Linux setup (as of 11/2021)

Description of my daily Linux setup as of November 2021

A couple of years ago I wrote a blog post about my Linux setup at the time. Well, understandably a lot of things have changed since then, and instead of updating a two year old post, I think writing a new one from scratch with the same principle and using the same template makes more sense.

One of the things I missed about Polybar is its internal CPU module, which can produce a core load graph directly in your bar by adding the right ramp characters. In this post I’m sharing a simple POSIX shell script I’ve written that does the same and can be used with any text-based bar. Here is what it looks like:

Wacom Intuos graphics tablet

I have a Wacom Intuos graphics tablet for my occasional drawing and signing. By default, the tablet area is mapped to the whole screen area, making it almost unusable if you are using two or more monitors, as your drawing application of choice (Krita in my case) usually resides in one display only. Well, turns out there’s a very easy way to map the tablet to a single display in Linux with xinput.

If you usually develop your software without an IDE, it may come in handy to be able to run a custom command or two whenever a file or a group of files in the file system is modified.
