In Knoppix, when one clicks log-out, the window that displays presents an option to "Save session for future logins." Does this option actually work in Knoppix running from a CD? If yes, exactly what does it save?

For example, during a Knoppix session I proceeded to change the wallpaper on my desktop. Later, I logged out of Knoppix and checked the box to "Save session for future logins." When I subsequently started up Knoppix again, the desktop wallpaper had reverted to the Knoppix default.

Thanks and regards,
Howard
