Bug Description

It would be most wonderful if an equivelent to casper-udeb/runlevel was introduced that allowed one to disable X and GDM/KDM from the LiveCD.

The runlevel option seems to have been removed. Likely because runlevels are meaningless with upstart. Even so, there doesn't seem to be any built in way to boot the LiveCD to a text console only.

Specifically, I have a server which I need to boot up with a removable media. My first thought was to use the LiveCD, but mearly starting X on this server causes it to hard lock, making it unable to return to the console.

As a temporary suggestion, I suggest a simple casper-udeb/textmode=true template which simply removes gdm/kdm rc scripts. Nothing more is required now.

When upstart starts handling service startup, maybe we could introduce support for micromanaging service state generically: casper-udeb/disable-jobs=gdm,kdm

It would be nice to have an ability to start another X-session by specifying some startup parameter.
For example on system with less than 256 MB RAM Ubuntu still can be installed from Live-CD by choosing XtermFailsafeSession (look at gdm.conf about this session description).
At least it would be nice to have an ability to run only X-Window system and Ubiquity installer, without starting whole GNOME with memory-hungry nautilus, gnome-panel, gnome-cups-icon, etc...

  * Fix gconf keys for suspend and hibernate (thanks, Oliver Grawert;
    LP: #144790).
  * Enable suspend again since as far as I can see we no longer need to
    probe DMI while figuring out whether to enable it (see #61535).
  * Add a 'textonly' boot option to disable X (LP: #65818).
  * Write the please-remove-CD message to /dev/console so that it works even
    if usplash isn't running, and make sure to set /dev/console into a sane
    state so that pressing Enter doesn't just result in ^M being displayed.
