Public bug reported:
I'm not sure if this is a bug or just there is no support yet for my system.
I have a Sony Vaio Z1190, Core i7, Hybrid graphics Intel Arrandale/nVidia GT
330M. I am running Ubuntu 9.10 Karmic AMD64, kernel version 2.6.31-20-generic,
nVidia drivers 195.36.15.

I try booting 'noapic acpi_backlight=vendor', unload or blacklist the
sony-laptop module (which also fails to adjust the backlight, ditto the
acpi video module, additionally I have tried to add the
"EnableBrightnessControl=1" to Xorg.org), then when I adjust the
backlight either via keyboard or directly with
/sys/class/backlight/nvidia_backlight/brightness, the system believes it
has made the change but no effect is seen.
Here is the effect to the kernel of nvidia-bl running 'debug=1' and changing
backlight to 0:

Please let me know if there is any more info that could help you to help
me out. Thanks!
