Default Re: Quadro FX 880M Stability Problems

I came here for a different reason, but these xorg additions allow me to have backlight control with my Lenovo Y450 laptop with GT 130M graphics. I learned of this after submitting a bug report with ubuntu and googling the "RegistryDwords" stuff that was suggested there

Then restart X and see if brightness controls work.

If they do, please post an nvidia-bug-report.log along with the make and model of your laptop. Thank you.
