I'm having an issue with session saving in Xubuntu 13.10. It saves the session on logout and opens up all kinds of programs when I first log in. The strange part is that some programs that weren't even open when I logged out still open at login. The settings in Settings Manager > Session and Startup > General are all set to disable session saving, but it still happens every time. If I go into Settings Manager > Sessions and Startup > Session, and delete the saved sessions the next login works fine. This may or may not be related to my other problem of some of the programs that are set to run at login using Settings Manager > Session and Startup > Session seem to start up for a second after login, but immediately quit. In particular, this is happening to Conky and Gtk-Redshift. I would really appreciate any help with this, since I have tried everything I can think of.

It's a bit extreme, and may mess things up for other users, but have you considered deleting some of the files in /etc/xdg/autostart? Also, I'm currently running LXDE, and the file /etc/xdg/lxsession/LXDE/autostart lists some autostarting applications
