3/7     My Ubuntu is running at default of init level 2 (runlevel) and it
        has X running. What the hell is going on? Shouldn't X be run
        level 5?
        \_ init level 3/5 is the way RedHat is.  This does not make it a
           standard.  In debian based systems, runlevel 2 is the standard
           operating unit.  You can choose to enable/disable running X at
           this run level.
