Default Re: Quadro FX 880M Stability Problems

Adding this line definitely activates the brightness controls on my Lenovo W510 - they work perfectly now. Ubuntu shows the on-screen display, the brightness level changes, all is well...

My machine does have a bit of a high frequency squeal but nothing that seems to be related to screen brightness. Seems like some W510's make some high frequency noise, some people have gotten their mainboards replaced over it.

My nvidia-bugreport output with working brightness controls is attached!
