Comment 56 for bug 562005

The latest certified nvidia blob (304.60) mentions this:

"Added support for the "Backlight" RandR output property for configuring the brightness of some notebook internal panels."

Could it be this is finally the fix we've been waiting for? Anyone tried this latest version yet? I just installed Xubuntu 12.10 and with nvidia 304.51 I still need to add "EnableBrightnessControl=1" to xorg.conf, and the brightness increments on my Thinkpad W510 are large and uneven, as always.
