[Bug 562005] Re: Backlight controls of laptops with NVIDIA NVS and Quadro FX 880M GPUs no longer function while using proprietary drivers

 

I tried commenting out the "EnableBrightnessControl=1" line and I'm unable to control the brightness. The on-screen popup shows me that the buttons are working and I'm changing the value, but screen brightness does not change.
So please consider my testimony in bug #613638 as incorrect, this does not seem to have something to do with the hibernate/suspend.
(Unless attaching an external monitor influences this behaviour. I had an external monitor connected when testing this. Will verify, but was probably just confused.)
