It's not (necessarily) about a PATH being there. Rather about you
putting one there, usually in the form:


(substitute as appropriate). Or append your preferred paths if you
want the usual suspects (/bin, /usr/bin, etc.) to take precedence.
Or both.

Looks pretty standard. Now do try putting a new file into Xsession.d
containing a line as suggested above and named, e.g. "97richards-path"
or something similar (92 means it happens near the end, the rest
is just for you to remember the perpetrator). Decorate it with some
comments. Remember, it's shell text which is "sourced" (i.e. included
as part, not executed in a subshell) by some bigger thing.

I'll believe that when I see it. I don't think they bypass the X11
session mechanism.
