New User needs help with the Tutorial

[Paul E Condon]

Thanks for the beautiful documentation, but this new user still manages to have problems:

I'm working thru the Tutorial. I've gotten to the place where I'm asked to type in 'Introduction' and change it's environment to Section (in section 2.2.1 of the Turorial)
The Tutorial says 'LyX numbers the section "1" and typesets ...'. But no number appears on the screen, or in the DVI output display. It seems to me that I should see a numeral "1".

This is a recent install of lyx from the Debian package in Debian Sarge. Install under Debian is such a straight forward process that I don't see how I could have messed up, but who knows. I have been known to do really stupid things.

Should I see a "1"?
If yes, where should I look for controls to turn it on?

Thanks,
Paul
