Building and Installing the Sway Wayland Window Manager on Debian 10 Buster
Wayland isn’t mainstream quite yet, but if you want to experiment with it and you prefer tiling window managers, then Sway is the way to go. However, building it on Debian requires a little work.
I tested the below script on a clean install of Debian Buster installed with just ssh server and standard system tools selected in task select. No desktop system was installed.
The only other packages I had installed were vim-nox, sudo, and open-vm-tools (I did this on a VM - vmware workstation with 3D acceleration enabled).
#!/bin/bash
# show commands as they are ran
set -x
# exit on first error
set -e
# meson must be newer than what's available in Debian packages to build wlroots:

# Additional prerequisites for sway. There are more if you want to be able to
run # X11 apps in Sway using Xwayland, but I just want to run native apps.

To start sway, from a virtual terminal you should be able to just type sway, however, with my hardware/VM, I had to set WLR_NO_HARDWARE_CURSORS=1 otherwise I had no cursor. Also, for Firefox, the MOZ_ENABLE_WAYLAND=1 environment variable must be set. For convenience, I just set that when launching Sway. So my actual command line to launch Sway looks like this:
WLR_NO_HARDWARE_CURSORS=1 MOZ_ENABLE_WAYLAND=1 sway
