Comment 9 for bug 297962

Jaunty jackalope can operate backlight as long as user doesn't install nvidia drivers. I noticed that when I launched live cd and installed it on my laptop. Backlight was changing when power was unplugged as well as I could operate it by using brightness applet (however it claimed it cannot read the brightness level). As soon as nvidia drivers (180.44) were installed, I lost control over the backlight.
