It's not very obvious to new users that 'Use graphical login' was a good
button to press.  It's partly because it's difficult to tell if the button
is already depressed (can't we have checkmarks or something?), and partly
because it's just not the default.

Perhaps it could be depressed if 'Test configuration' works.  Or perhaps
'Test configuration' should do as Xconfigurator does and ask not only if
you can see this message but also if you want a graphical login.

Speaking for the support guys in the UK, we often get calls like 'I just
get the DOS prompt, what now', and it's because of this.
