Multiload-Qubes

2026-11-01

During the last ten years or so, I got really comfortable with the good old indicator-multiload by Michael Hofmann: a compact system monitor charts right in the desktop panel.

At some point it stopped working normally in modern DEs, and Mario Cianciolo has reimplemented it as multiload-ng.

And then, as part of my efforts to learn Qubes OS (and maybe migrate to it eventually), I had to find out that none of these existing projects are usable on Qubes because of its security-focused architecture; a very different approach is needed to implement the same functionality.

No one has done that, and since as I said I got too comfortable with it and didn't want to give it up, I had to implement it myself:

Check it out on github: multiload-qubes
