Public bug reported:

Binary package hint: xorg

I first noticed that my screen was too bright and tried to adjust the
brightness with Fn-F5.  Nothing happened right away, but after that
something that looked like a brightness control bar would pop up on my
screen every minute or so and then disappear.  There was no way I could
get at it.  I also tried using the brightness control in Power
Management, but it did nothing at all.

The tail of xorg.0.log looks like this (it doesn't seem at all helpful):

-hsync -vsync (47.4 kHz)
