    When using KDE, you have the option to start a new session in the start menu. You are then presented with a new login screen.
    The annoying thing though, is that you have no info on who is already logged in into one of those additional X Sessions.

      Open a terminal shell (bash, xterm, etc). Type the letter “w”, press enter… Shows you who’s logged in. No matter what tty they’re logged in to. You don’t have to be root to run the command. It will even show remote users logged in to your machine.
      Cheers ;)

    Hello,

    If You want launch a simple Xorg session with the next command line :

    # Xorg :0 (control+alt+F7)
    # Xorg :1 (control+alt+F8)

    (which is lauched by startx — :1)
