Public bug reported:
Laggy behaviour of the brighness control keys: there is a delay between
key strokes and brightness changes with the brightness control keys, and
at least 2 key strokes are required for any brightness change. This
happens usually on the next boot changing from AC to Battery or vice-
versa, and is only fixed with a reboot; If no change is done to power
method, brightness control works fine;
A way to reproduce is to boot with AC plugged, unplug the AC cord, and
then reboot 1 or 2 times;
Using nvidia-experimental-310, Ubuntu 12.10, and Gnome Shell 3.6, but
such behaviour was already present with nvidia-current and nvidia-
current-updates, and both with Ubuntu 11.10 and 12.04;
This is perhaps hardware-specific. I'm on a Sony Vaio VPC-S13, with
Intel i5-460 and Nvidia 310M;
Brightness control keys are enabled with "Enable BrightnessControl=1" on
/etc/X11/xorg.conf. Sending the file in attachment.
