Other hardware seems also affected, e.g an Nvidia GT330M in this thread: http://ubuntuforums.org/showthread.php?p=10505235 Neither the keyboard keys nor the brightness applet slider works, the applet icon showing a stop sign as usual when brightness adjustment is not available. Adding this to xorg.conf makes it somewhat work again after a reboot. Option "RegistryDwords" "EnableBrightnessControl=1" However, this makes only the adjustment work as such; I still don't get the notification bubble that appeared with previous drivers, and which still appears in Natty when I use the nouveau drivers.
