display brightens unexpectedly on input running with battery

[Jerry Quinn]

Binary package hint: gnome-power-manager

While on battery power, I'm observing that screen brightness misbehaves. The machine is an ASUS 1000HA.

I manually push the brightness down all the way using Fn-F5. I am reading a document and periodically scrolling or paging using either keys or touchpad scroll feature. Sometimes when I provide an input (it doesn't matter whether it's keyboard or touchpad) the brightness will go up to full and I have to manually force the brightness all the way down again.

If I've told the system I want the display fully dimmed, it should never exceed that setting even when it sees I'm no longer idle.

I am using the default settings for the power manager.
