Think twice before abandoning Xorg. Wayland breaks everything!

Hence, if you are interested in existing applications to "just work" without the need for adjustments, then you may be better off avoiding Wayland.

Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating everyone else (e.g., people using just an X11 window manager or something like GNUstep) in the process.

Wayland proponents make it seem like Wayland is "the successor" of Xorg, when in fact it is not. It is merely an incompatible alternative, and not even one that has (nor wants to have) feature parity (missing features). And unlike X11 (the X Window System), Wayland protocol designers actively avoid the concept of "windows" (making up incompr

Connecting to a Raspberry Pi through a VPS using a reverse SSH tunnel

SSH (Secure Shell) to a host existing in an internal network through a reverse-tunneled SSH connection to an externally accessible VPS (Virtual Private Server). This setup is described where the internal host is a Raspberry Pi, but can be generalized for any host on the internal network that runs an OpenSSH server.
