Somewhat to my surprise, xterm isn't recognized as a command
on the RasPiOS end. The default terminal emulator is lxterminal,
but I thought xterm would still be recognized. Evidently not.

The RasPiOS system boots to the command line and the windowing
system is started up using startx. The man page for startx seems
to imply that the Pi is using some flavor of X, but I'm not sure
which one. Xwayland is available, but not installed.
