During Knoppix's start-up, I get a fleeting glimpse of about
a half screen-full of text. It goes by so fast I've never been
able to see what it says.

I'm pretty sure its not dmesg or Xorg.o.log or .xsession-errors.

I'd like to know if there is a record after start-up is over
that shows what it said, or failing that, is there a virtual
terminal where it might have been seen for a little longer?
