Which terminal emulator do you use? E.g gnome-terminal is implemented as 
a user service and might be affected.

After logging out, how long did you wait before logging in again?
I vaguely remember that there is a timeout before an idle user session 
is terminated.

Or do you have lingering enabled, so user sessions are deliberately not 
terminated?
