I use Debian and I also was affected by this Windows update. I was able to boot by disabling secure boot. I also found this option that apparently fixes the problem by changing the sbat policy using mokutil. But I haven’t tried it out yet. Has anyone got any luck with something else besides disabling secure boot?

No, it’s just something I’d like to learn

Thanks! You’ve all convinced me to try Sway. As soon as I have time to dive into the configuration, I’ll give it a shot!

I would like to give a proper try to a tiling window manager. I would like to try QTile, but I haven’t gone through the documentation to understand how to customize it properly. Currently, I use GNOME (and actually, I like it a lot). Also, I love TMUX, and the idea of having the same flexibility and keyboard-centric experience on a broader level makes me think that I will love a tiling window manager when I try it. I’m interested in QTile because I know it’s configured in Python (which is a programming language I already know), and apparently, it can be used on either X or Wayland. Have you ever tried using it on Wayland? Does it work properly? Besides QTile, what else would you recommend?
