I am using an ARM version of Ubuntu (Lubuntu specifically) on a pcDuino. I want to use it as more of a server as opposed with a monitor. One of the first obvious things to do would be to disable lightdm/x starting on boot. I googled it and everyone is saying you just need to edit /etc/default/grub but grub is not used to boot the ARM version and is therefore not installed.

Any help would be appreciated. Thanks

Which ARM image did you download for use? – Stephen Michael Kellat Apr 20 '13 at 12:51
The latest version here which I believe is Linaro. – roryhughes Apr 20 '13 at 21:11

Okay, run levels for Ubuntu and flavors is handled by the Upstart system. To bypass going straight to graphical mode, you'll need to change the run level as stipulated in the Upstart cookbook. The Ubuntu default is graphical multi-user plus networking.

To switch to single user mode, you'll need to enter the command sudo nano /etc/init/rc-sysinit.conf and enter the appropriate password to open the file for editing. Once open, hit Control-W to search for env DEFAULT_RUNLEVEL and change what is on the other side of the equal sign to 1. Hit Control-X, and yes to the prompts, and leave nano to finish your editing. Reboot and you should come back up in single user mode without going straight to a GUI.
