Reading the changlog of lubuntu default settings suggests that it might be this package as that loads the pcmanfm desktop for that.
lubuntu-default-settings (0.45) xenial; urgency=medium * src/etc/xdg/lubuntu/libfm/libfm.conf * src/usr/share/lxpanel/profile/Lubuntu-Nexus7/config * src/usr/share/lxpanel/profile/Lubuntu/config - Set lxterminal as the terminal by default, until lxsession-default-terminal is fixed (LP: #1434774). * src/etc/xdg/lubuntu/menus/lxqt-applications.menu - Exclude synaptic-kde.desktop in LXQt menu, until OnlyShowIn is fixed in LXQt (see bug #582). Thanks Ariszlo for the patch. * src/etc/xdg/pcmanfm/lubuntu/desktop-items-0.conf * src/etc/xdg/pcmanfm/lubuntu/pcmanfm.conf - Update some pcmanfm default settings and activate mounted devices on the desktop by default. * debian/control: - Provides lxqt-common to be able to install lxqt-session (lubuntu-default-settings also should provides all functionnalities of lxqt-common). * src/etc/xdg/lxqt/panel.conf - Remove lxqt-panel.conf until xdg dirs are correctly used. * Translations update. -- Julien Lavergne <gi...@ubuntu.com> Sat, 27 Feb 2016 16:13:04 +0100 ** Also affects: lubuntu-default-settings (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1551446 Title: xenial amd64 dialy boots to black wallpaper in live session.
