Gibberish on switching X to console

[Anthony Campbell <a.campbell@doctors.org.uk>]

I've just installed Debian on my son's computer; everything has gone
pretty smoothly except that when I switch from X to a console I
frequently get gibberish. I can't clear it with reset, tty sane, or 
ctrl-v ctrl-c and I have to reboot,

I seem to have read something about this one but I can't remember where.
Any suggestions gratefully received.

Anthony
