I don't believe this! I have I can effect the brightness with xrandr, but the
output name is 'LVDS-0' instead of 'LVDS' (as it is on my other laptops). I
don't know if this could be the whole problem with the normal backlight
controls not working -- anyone have any idea? I'll just modify the xbacklight
script to call xrandr instead of xbacklight and pass it fractional values
between 0.5 and 1.0. Strange indeed.
