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
