There's no reason for programs to daemonize for the desktop session. If they are, it's a bug. Most likely it's just a case of someone thinking their program is l33t because it's a "daemon". > That's why we need to iterate over the process list and send SIGHUP to > processes matching the uid and XDG_SESSION_COOKIE (or other attribute > but XDG_SESSION_COOKIE is what we have right now).

The idea is just to have a binary which monitors X11/DBus, and can fork()/exec() a child binary to monitor. If X11 goes away, it kills the child. Thus the only thing that needs to be modified is that the session startup script is changed from: some-random-daemon --args to: dbus-scope-to-session some-random-daemon --args > > But I think (generally speaking) most > > projects nowadays *should* gain a dbus dep, and if we can explain > > clearly to them why it it useful, they would accept it. > > I think that is what they call wishful thinking. Seriously. Let's be more concrete here - what other apps are buggy? -- Fedora-desktop-list mailing list Fedora-desktop-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-desktop-list
