Public bug reported:

Binary package hint: xserver-xorg-video-nouveau

I use nouveau driver on my laptop Sony VAIO F13Z1R with GT425M.
When it returns from suspend backlight control does not work.

I use nouveau driver because of more cofmortable baclight (no gradient
or dim at low brightness levels). See comments on
http://code.google.com/p/vaio-f11-linux/wiki/AutoDimmingBacklightDaemon
for better understanding what I mean.
