Can I add a 'me too' to this bug please.  I've been wondering why my
screen doesn't turn off properly - i.e. it goes blank but with the
backlight on still - and Colin's message suggests that what I'm seeing
is a bug.

I'm seeing the same on both a desktop machine (with Intel graphics) and
on a laptop (Acer Aspire), both running xubuntu 11.10.
