kde includes some kind of "session management". as far as i know this is
not the icccm compliant standard x11 session management, however, and last
time i checked the whole session management thing was a huge mess and most
applications simply ignored it. session management means that a window
manager/desktop environment can ask applications to save their state and
tell the wm/de how to restart them with the same state they exited before
terminating a session and restarting these applications at the beginning
of the next session. most people do not seem to respect the standard,
however and everyone seems to do his own thing (perhaps this has changed
now, the last time a seriously looked at this was a few years ago). i
don't consider session management a reliable way to terminate a session
without loosing data today and so it's simply not implemented in ude
(better not have the feature than give a false impression of security).
if you want to log off cleanly close your applications manually one by
one, saving open files, and then exid ude/uwm. this is the only really
reliable way i know. if someone knows wether this has changed, don't
hesitate to send me a hint.
