Terry, we try not to top-post on this list. Just a gentle nudge.

Terry's comments are correct. System-level things should autostart at
boot if they're enabled via "systemctl enable blah" or "chkconfig blah
on" and the startup scripts don't abort if old PID or "/var/run" files
are left around. Note these are SYSTEM services--not user-specific
items.

gedit and such are desktop applications and won't autostart unless
they're configured to start on session startup. Session startup won't
occur until you log in as the desktop user OR you have auto-login of
your user set up.

If you've snapshotted your session (e.g. under XFCE, go to
"Applications", then "Settings", then click on "Session and
Startup",
select the "session" tab and click the "Save Session" button), then
your session should be restored to that state when you log in--but only
to the level that the individual applications (and session manager)
support session snapshotting. Not all do. I use XFCE with the
xfce4-session session manager and xfwm4 window manager and they do a
fairly decent job of snapshotting. Not perfect, but reasonably good.
