[Lxde-list] lxsession issues

[Marty Jack <martyj19@co...>]

I posted a patch for the missing lxsession-logout icons.

The wiki says that dbus/hal are required to get restart, shutdown, suspend buttons.  As best I can tell, this is incorrect.  Only suspend depends on hal, and restart and shutdown depend on having the GDM control socket.  The second issue is that the GDM control socket appears to have been removed starting after GDM 2.20 when it was rewritten to use dbus.  I do not have GDM so cannot confirm this.  Maybe someone else on the list can comment.  If true, at some point the code in lxsession that tries to interface to GDM should either be removed or rewritten (that might make a nice learning project for someone).

The other lxsession issue we have is that applications are rudely terminated when you log out.  This is easy to reproduce (start firefox, log out, log in, start firefox, it complains it crashed).  My research indicates that GNOME sends SIGTERM, and KDE uses DCOP (or whatever the KDE4 equivalent is) to get applications shut down.  We need to discuss and decide whether LXDE should make any attempt to do a more graceful shutdown.
