switch temporarily to headless mode or runlevel 3?

  • 772

I've installed ubuntu 10.10 x86_64 desktop version, which defaults to Xorg login

I want to temporarily switch this machine to server mode, basically i "suspect" this entails setting to runlevel 3 and headless mode somewhere

what are the details of this? Also very important is how do i re enable desktop mode again?

server

  1. AFAIK Ubuntu doesn't use the runlevel, in fact the /etc/rc*.d directory are the same. If your goal is to not run Xorg automatically just edit /etc/default/grub and modify the line:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

    in

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash text"

    then type:

    sudo update-grub

    to switch back delete "text" and re-run sudo update-grub

    If for headless or server mode you mean without graphical interface, it is sufficient to stop gdm:

    sudo stop gdm

    so that you remain only with virtual consoles.

    To enable again the graphical login, start gdm:

    sudo start gdm

    Be aware that this can make your network stop working.

    To avoid this it is probably enough to set the connection as a System connection in network manager

  3. Try running this command:

    sudo telinit 2

    That'll make the system go to runlevel 3, if you want to get back to "normal" re-run the command like this:

    sudo telinit 5
