Kubuntu 12.04 boot to text mode

    I am attempting to configure Kubuntu 12.04 to boot by default in text mode. The
    power usage and boot delay are slowly becoming unattractive.

    I've modified my grub.cfg (no, not directly) to the tune of:
    Code:
    #GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    GRUB_CMDLINE_LINUX_DEFAULT="text"
    GRUB_TERMINAL=console
    I've run update-grub2, and am certain these settings have taken effect because
    the splash screen no longer displays, but it still boots to KDE.

    I've done some light reading on initscripts/upstart/runlevels, and suspect that
    these will get me what i'm looking for, but don't really know where to make my
    changes without potentially crippling the system.

    I have read a number of threads that report that the grub method was successful,
    but nothing that dealt with Kubuntu or precise pangolin. These are the only
    differences i see that might be causing these results.

    Any help is appreciated.
    Thanks in advance.

    Update:

    Update: Nearly certain that kubuntu is what is making this difficult. Made the same modifications in grub to ubuntu 10.04, and it booted in text mode. Am now comparing boot sequence differences between 10.04 text mode, 10.04 graphical mode, and kubuntu.

    I guess KDE is started by some init script in /etc/init.d/. Can you post the output of
    Code:
    ls -l /etc/init.d/
    ?

    what do you mean to boot in text mode?

    Do you want to see just text at boot up instead of the start image but then still enter KDE

    Or do you want to boot up without start X/KDE?

    Falko: the output of "$ ll /etc/init.d/"

    So the kdm is an upstart job. I took a look at /etc/init/kdm.conf and did some
    more googling on GRUB_CMDLINE_LINUX. According to
    http://askubuntu.com/questions/16371/how-to-disable-x-at-boot-time (because i assume
    the .conf files would be at least vaguely similar across desktop managers),
    there ought to be a statement in kdm.conf that checks for the 'text' argument.
    Here is the original file:
    Code:
    # kdm - KDE Display Manager
    #
    # The display manager service manages the X servers running on the
    # system, providing login and auto-login services
    
    description     "K Display Manager"
    author          "Richard Johnson"  
    
    start on ((filesystem
               and runlevel [!06]
               and started dbus
               and (drm-device-added card0 PRIMARY_DEVICE_FOR_DISPLAY=1
                    or stopped udev-fallback-graphics))
              or runlevel PREVLEVEL=S)
    
    stop on runlevel [016]
    
    emits login-session-start
    emits desktop-session-start
    emits desktop-shutdown
    
    env XORGCONFIG=/etc/X11/xorg.conf
    
    script
        if [ -n "$UPSTART_EVENTS" ]
        then
        [ ! -f /etc/X11/default-display-manager -o "$(cat /etc/X11/default-display-manager 2>/dev/null)" = "/usr/bin/kdm" ] || { stop; exit 0; }
    
            if [ "$RUNLEVEL" = S -o "$RUNLEVEL" = 1 ]
            then
                # Single-user mode
                plymouth quit || :
                exit 0
            fi
        fi
    
        if [ -r /etc/default/locale ]; then
            . /etc/default/locale
            export LANG LANGUAGE LC_MESSAGES
        elif [ -r /etc/environment ]; then
            . /etc/environment
            export LANG LANGUAGE LC_MESSAGES
        fi
        export XORGCONFIG
    
        exec kdm
    end script
    
    post-stop script
        if [ "$UPSTART_STOP_EVENTS" = runlevel ]; then
            initctl emit desktop-shutdown
        fi
    end script
    after reviewing the file, i added the following statement between the upstart arguments
    block and the /etc/default/locale block:
    Code:
        # check kernel command-line for inhibitors, unless we are being called
        # manually
        for ARG in $(cat /proc/cmdline); do
            if [ "$ARG" = "text" ]; then
                plymouth quit || :
                stop
                exit 0
            fi
        done
    This seems to work: i am having some slight issues subsequently restarting kde, and will post any relevant information here.

    Thank you both for your input.
