That only works if you have a relatively new graphics card and a  
relatively new LCD monitor. Or if you want the default settings for  
various options. If you want to change the defaults, or you have a CRT  
(especially and old one) you need a conf file.

A really bad combination is a relatively modern display card such as  
an NVIDIA or ATI with 128m of RAM or more and and an old CRT.

I don't know if it is an UBUNTU thing or the real default, but control- 
alt-plus and control-alt-minus (switch resolution) and control-alt- 
backspace (kill X) are disabled.  So you can't keep switching until  
you get one that works and then set it permanently, or keep killing X  
until you get  a text screen.
