The 'ubuntu' flag, which is enabled by default, causes the gnome-screensaver to look for the key 'ubuntu-lock-on-suspend' in the settings scheme 'org.gnome.desktop.screensaver' The exact error is: $ gnome-screensaver (gnome-screensaver:15561): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.screensaver' does not contain a key named 'ubuntu-lock-on-suspend' Trace/breakpoint trap Removing the use flag allows for the screensaver to start as normal.
