Originally my T61 BIOS was set to have a dimmer backlight when on battery power, and not even xbacklight 100% could bring it back up to full brightness. I changed the BIOS, and now have full brightness on battery.
Except when I run mplayer. It seems that if I run mplayer on battery, my backlight brightness drops and stays down, and when I next run mplayer on AC, I get the full brightness back.
This probably relates to the xv acceleration, somehow.
