I am using Ubuntu Linux (Gutsy Gibbon): $ uname -a Linux loki 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008 i686 GNU/Linux By "single user mode" I talk of, I mean "single" parameter being passed by Grub bootloader during startup: kernel /vmlinuz-2.6.22-14-generic root=UUID=7bb7e9b4-7134-430d-b2bb-cd33c45d0acd ro single initrd /initrd.img-2.6.22-14-generic I am able to also reach this mode by doing "init 1". I understand that this is supposed to be a spartan recovery mode or for situations where you don't want multiple users. But in context of my home setup, I wanted to use this to avoid starting up too many services/X/Gnome etc since all I want to do is run some long-running command line programs (for which screen is more than adequate and in fact, perfect). My intention is to use least amount of CPU/memory. I have noticed that even in this "single" mode, there are services like ntp running and the network interface is already configured so I am able to access internet. So it is not that Nothing is running. > If you want a textual login then start up normally, and choose "Other..." at the login window prompt and enter > ">console" (without quotes).

I don't see these choices when I go into the "Single" user mode or when I start normally and get to GDM (Gnome Display Manager). So not sure how to enable this. As I said, I don't want to run X etc. Hope this information is of help to you for suggesting a/the solution for me :) Regards, Soumen
