boot ubuntu 10.04 “Lucid Lynx” in text mode

Ubuntu 10.04 “Lucid Lynx” has been released, and what I wrote in my last post is still relevant.

I did another search to find another good way to boot the OS in text mode, getting rid of gdm at boot.

Inbetween several instances of advice like removing /etc/rc2.d/S30gdm, which does not exist any longer since gdm has been moved to upstart, or getting rid of gdm altogether by uninstalling it, which I didn’t want to do, I found something interesting in a comment to an article:

You need to open the /etc/default/grub file, locate the following line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

and change it to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash text"

and don’t forget to run update-grub afterwards to update.

In more general terms, you may want to add the text parameter to the GRUB entry for which you want a text-mode boot. Changing the default GRUB command line postfix, which is appended to all entries, rather than changing a single entry, seems like a brutal solution, but it is also the quickest, and may be just what you want.

A little bit of explanation: the upstart script /etc/init/gdm checks the kernel command-line for inhibitors such as text, and quits if it finds one:

        for ARG in $(cat /proc/cmdline)
        do
            case "${ARG}" in
                text|-s|s|S|single)
                    plymouth quit || :  # We have the ball here
                    exit 0
                    ;;
