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/
?

sjau 4th July 2012 15:33

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?

Update: solved
 
jau: The second; disable X and KDE until i manually run "$ startx" or somesuch.

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...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.
