As Julie Lavergne noted today in a post with Subject: 'Back on 13.10 release,' lxsession-edit (Preferences: Desktop Session Settings) has been removed from 13.10. It has been replaced by lxsession-default-apps (Preferences: Default Applications for LXSession). I think you and I had some previous exchange on this topic. But the layout and functionality of lxsession-default-apps seem confusing. You might think that its Autostart tab was intended to replace lxsession-edit's functionality, but as far as I can tell so far, it's major function is to disable/enable whole classes of autostarting apps. There seems to be a provision for manually adding and controlling single apps, but there is no pre-populated list as there was with lxsession-edit. In any case, on the Running Applications tab, I edited Network GUI: nm-applet and set that to NO. This results in only one instance of nm-applet running for that user. The edit must be repeated for all users. [There is undoubtedly a global configuration that would fix that, but it does not seem to be achievable through the GUI, and I have not found documentation for accomplishing that directly in a configuration file.] But I still don't know where the other instance of nm-applet is launching from. /etc/xdg/lxsession/Lubuntu/autostart is empty, as is ~/.config/lxsession/Lubuntu/autostart. And there is no *.desktop entry for nm-applet in the ~/.config/autostart folder. </blockquote> After some further research, I found that the still-enabled instance of nm-applet is auto-starting from /etc/xdg/autostart/Network.desktop. But I also found that /etc/xdg/lxsession/Lubuntu/autostart and ~/.config/lxsession/Lubuntu/autostart are both empty files. So in lxsession-default-apps, when I set changed Network GUI from nm-applet to 'no', what was it writing that setting to? </blockquote> I don't have a full grasp of this, but now know another piece of the puzzle. I already understood that LXSession will autostart apps from these locations: /etc/xdg/lxsession/Lubuntu/autostart (command file) ~/.config/lxsession/Lubuntu/autostart (command file) /etc/xdg/lxsession/Lubuntu/autostart (autostart directory containing *.desktop files) ~/.config/autostart (autostart directory containing *.desktop files) But now I understand that the new LXSession tools will also autostart many apps from these conf files: /etc/xdg/lxsession/Lubuntu/desktop.conf ~/.config/lxsession/Lubuntu/desktop.conf (this is the more important file and takes precedence in case of conflicting entries) With some of the apps that may be started via desktop.conf, there is an autostart option to control whether or not the app autostarts. But in the case of the network manager GUI, if a command is specified (e.g. network_gui/command=nm-applet), it autostarts -- there is no option not to have it do so. Lxsession-default-apps (aka menu Preferences: Default Applications for LXSession) reads-from/writes-to ~/.config/lxsession/Lubuntu/desktop.conf, so settings made this way are per-user.

For instance, the location of desktop.conf, or additionally, that there are actually two locations, and that the user-location version prevails. Also that lxsession-default-apps reads/writes only the user-location version of desktop.conf. In fact, as far as I know, lxsession-default-apps is currently documented very lightly. (I could add for others who are newbies or not-long-exited from that status that all of the above addresses only application autostarts occurring after user login. Service/daemon control uses a whole other scheme.) </body> </html>
