quit applet: logout does not work on Hardy

[Mark Lee]

Computer Info:

Ubuntu Hardy 8.04.4 (GNOME 2.22)
Awn 0.4.1 bzr revision 690 + fix in Bug #565174
Awn Extras 0.4.1 bzr revision 1289 + fix in Bug #565792
Both installed from ppa:malept/experimental

Bug Info:

When I click on the "logout" icon, nothing happens. I expect that the session logout dialog is shown. I think that this bug is similar to bug #565792, in that the gnome-session in GNOME 2.22 does not provide a DBus interface as it does in later versions, so either detection or execution is failing.

The solution should probably be when the quit applet can't find a DBus interface, it should check for the existence of gnome-session-save (and possibly a GNOME environment variable, much like xdg-open), and if found, it should fall back to executing `gnome-session-save --kill --gui`.

The applet already checks whether it can find the DBus interfaces. Go to /apps/instances/awn-applet-quit/awn-applet-quit-UID/ where UID is a number (use use ps auxf or htop or whatever to find this) and then modify the value of log-out-command and lock-screen-command.

This applies to gconf. For the keyfile backend look in the ini or whatever it uses.

Argh.. it's you. Then I don't need to tell you how this works :p

[Mark Lee (malept)]

Well, I'd argue that it's a usability issue, as people expect these applets to "just work".

Sorry but hardy is just too old for me. I once asked in #awn whether there were people who knew how to detect kde and xfce, but no one answered.

Patches are welcome.

[Mark Lee (malept)]

I can tell you exactly how to detect it, but I won't code it myself.

KDE:
See http://www.purinchu.net/wp/2009/06/12/oh-fun/ for the KDE session manager logout behavior.

Xfce:
cairo-menu has the DBus interface address for the Xfce session manager, in gnome-menu-builder.c.

GNOME:
If the DBus interface for GNOME's session manager isn't found, check for the environment variable GNOME_DESKTOP_SESSION_ID. If that's found and gnome-session-save exists in the PATH, use that.

I'll take a look at it.

I am closing this bug report because Hardy is not supported anymore. Gnome 2.22 is really too old and I am not able to test any code for XFCE and KDE.
