How do I make X start at boot? [SOLVED]

[cantab]

I'd configured my computer to not start X at boot (because it was running as a server for a while). And now, I've forgotten what I did. How do I make it start X at boot?

UPDATE:

Solved by running the following

sudo update-rc.d gdm defaults

(If running kdm it would be that instead of gdm)

Re: How do I make X start at boot?

I am not sure how you did it, but what causes it to start in Kubuntu is a link in /etc/rc2.d to /etc/init.d/kdm. If you are using Gnome you are probably using GDM instead of KDM and you may have used some GUI tool for editing the SysV links. In Kubuntu 8.10 you would "cd /etc/rc2.d" and ls -l should show

lrwxrwxrwx 1 root root 13 2009-02-24 13:02 S30kdm -> ../init.d/kdm

If it does not, create the link with
sudo ln -s ../init.d/kdm S30kdm

If you need gdm instead, just substitute gdm for kdm.

sudo ln -s ../init.d/gdm S30gdm

If you used a GUI SysV editor to disable it you should probably use that to enable it also.
