As Tyson mentioned in comment #28, this is a timing issue that gsettings-data-convert.desktop is executed before gconf value is set for guest session.
One of workaround to use gsettings is to put a prefs.sh in /etc/guest- session which does: echo "[Desktop Entry]\nType=Application\nName=Disable Lock Screen in Guest Session\nOnlyShowIn=GNOME;Unity;\n\ X-GNOME-Autostart-Phase=Initialization\nTerminal=false\n\ Exec=gsettings set org.gnome.desktop.lockdown disable-lock-screen true\nNoDisplay=true" \ > $HOME/.config/autostart/disable-lock-screen.desktop chown $USER:$USER $HOME/.config/autostart/* This will make sure the gsettings value of disable-lock-screen can always be true for guest session. ** Attachment added: "prefs.sh" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/951000/+attachment/3707106/+files/prefs.sh -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/951000 Title: disable guest session screen lock using gsettings To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/951000/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
