Public bug reported: The dm-tool "lock" command does not bring up the normal lock screen (achieved when using Unity by hitting Ctrl+l), but rather a user switcher screen that allows for logging in as another user. It also has a few other different properties, like showing an accessibility icon (not displayed in the regular lock screen and stopping any playing music (which continues to play in the regular lock screen).
It seems to do the exact same thing as the command "dm-tool switch-to- greeter." This has the side effect of, since Ubuntu 14.04, making it impossible to lock the screen from the terminal. See here for a discussion of older methods that no longer work: http://askubuntu.com/questions/457204/how-can-i-lock-the-screen-using-the-new-lockscreen-from-the-command-line Thanks.
