This posting is intended to function not only as a tutorial but, also, as a review and commentary on my ‘long-term’ use of spectrwm as my primary window manager (long-term, meaning at least one month of daily use).
I really liked spectrwm the few times I've tried it. My only issue is that it's on Xorg and that means that, much like AwesomeWM and others, they will die with Xorg unless they get ported to Wayland (which is a truly difficult task
Correction: they'll be dead with the next few years. If everything goes to plan by 2027, pretty much everyone will be on Wayland (Because in 2025, all surviving desktops and WMs will be completing full Wayland transitions, and we can give distros and users 2 more years to reflect that). While Xorg will be officially dead when it becomes abandonware after RedHat drops it in 2032 (when the last RHEL 9 version, 9.10, will stop being supported), Xorg will already be all prepped up for its funeral and burial years before then.
Here's a prediction: not even fedora will drop it by 2027.
Wayland still doesn't work for a lot of people, and the ecosystem is nowhere near mature enough. I doubt enterprise distros will consider dropping xorg until their users can actually work on Wayland.
Defaulting to it and dropping it are completely different, and seeing the pace of progress in the last year or 2 makes me feel very confident that Xorg will be abandoned by 2027.
