Also, it's not guaranteed that any particular script is executed, since
that's all configurable. I don't know if any of the traditional X11
startup scripts are running on my Ubuntu system, but I used the Ubuntu
MythTV guide to add a new gdm session in /usr/share/xsessions which runs
a script I wrote to start mythfrontend. I think that this path is
supposed to hold session definitions for more than just gdm, so kdm
might use them as well, but I haven't tried it.

Unfortunately, there are so many different ways to start an X session
and so many different scripts and executables involved that it can be
difficult to determine exactly what's running when. One method for
testing is to put something like "xmessage test!" in a script where you
want to run something like "xset s" and watch for a small dialog box
with "test!" in it to appear. If it shows up right at the beginning of
the X session, that's probably a good place to put xset commands. Also,
if there are any commands after xmessage, they won't run until you click
"okay".
