Note sure if it's a dupe. I'm seeing the problem on Jaunty with a 2.6.28
kernel, so it probably isn't.

One note about this bug: I tried running on kernel 2.6.29-rc4 and with
that kernel the values in
/sys/devices/virtual/backlight/acpi_video0/brightness work properly.
That is, the values from 0 to 13 correspond to the backlight where 0 is
lowest possible and 13 is highest possible. However, the userspace tools
didn't work the way they should. Neither xbacklight, gnome-power-
manager, nor the fn-keys worked well. The changed the backlight in what
seemed to be a random manner.
