laptop backlight is dim after I wake it from a dpms off

Hi,

After a "xset dpms force off" (or a timeout from X that turns off my screen), when I wake it with a mouse/keyboard, my backlight is at the lowest setting.  I have to manually turn the brightness up every time even when the brightness is at 100% when the screen turns off.  I am not using xscreensaver or anything like this, I'm just setting timeouts with xset dpms.

Any thoughts?

Thanks,
Erik

xrandr --output LVDS --set BACKLIGHT_CONTROL legacy

This fixes the issue, but I still don't know why, and I don't like the fact that I have to use "legacy".  If anyone can clue me in on more info that would be great.
