Bug Description
Backlight control on Hardy is dependent on xbacklight, for Sony Vaios with Intel display adapters. In intrepid, backlight dimming does not require xbacklight and Fn keys are properly mapped. In both scenarios running the following command is necessary for the backlight to respond to input.
$ xrandr --output LVDS --set BACKLIGHT_CONTROL native
if you are experiencing bug #258920 (backlight oscillates slowly), this option may be more appropriate:
$ xrandr --output LVDS --set BACKLIGHT_CONTROL legacy
Sony Vaio SZ650N, Intel GM965 / GMA X3100, 'intel' driver.
This bug has been duped and unduped a couple of times with no improvement despite the mother-dupes being fixed, so I'm making it independent again.
