I would NOT advise modifying the files in /etc/X11, especially if you
aren't 100% sure what you're doing.  There are lot of subtle and delicate
moving parts in there.

Whatever you end up doing to get your PATH set properly at login should
happen only in your $HOME directory.

Start with .xsessionrc (the Debian hack) and see if that works.  Put a
PATH modification in there, and also put something like

export GENETEST=hello

and see if that's present in a shell inside a newly spawned xterm.
If it is, then you know that .xsessionrc is being read during login,
even if the PATH modification is lost.

If GENETEST is present but the PATH modification is not, then you know
something's changing your PATH after .xsessionrc has been read.  In that
case you need to track it down inside your desktop environment.

If neither one is present, then you're not using a Debian X session.

Whatever the results are, you'll have learned *something*.
