Gnome feedback when adjusting the display brightness

After updating the kernel to 2.6.31.9, I was pleasantly surprised to see
that my laptop's ACPI keys for adjusting the display brightness are now
working, for the first time ever.
On another laptop, whose display brightness ACPI keys have worked for a
while, there's a large icon that pops up on the Gnome desktop when I adjust
the display brightness level. It sort of looks like a big lightbulb, with a
slider underneath that scrolls horizontally, when I change the screen's
brightness level.
On this laptop, the lightbulb does not pop up, only the display brightness
changes. The only difference that I can think of is that the other one is
running compiz (and the big lightbulb comes up as a semi-opaque overlay over
the desktop), and this laptop's video hardware does not have accelerated
support, so no compiz here. Would that be it -- just curious.
