Comment 10 for bug 367309

I burned the Karmic Koala Alpha 2 64-bit desktop image to a CD-RW, booted off it, and tried reproducing the problem using the steps in comment 0:

 - Brightness keys on the keyboard can now turn the backlight off, which was not previously possible.
 - Brightness keys now navigate a reasonably smooth gradient from full-bright to off.
 - xrandr's BACKLIGHT_CONTROL still defaults to 'native'
 - xrandr's BACKLIGHT property, under 'native' control, still exhibits all the
strange odd/even behaviour mentioned in the original comment.

I would say this bug has become less urgent, since my brightness keys now work properly without intervention, but the underlying problem is still present.
