Lubuntu - root password at install time?

[mahesh]

like the title says.

I've just installed Lubuntu and am trying to set up Samba and Apache. I'm fed up of typing "sudo" befor every command, so would like to switch to being root. I assumed no password at install time but this does not work. I tried my username password and "password" - those don't work either. Can anyone enlighten me, please?
