How to enable brightness control on Dell Inspiron 15R (N5150)

[Jithin.C.V]

Hi All,
I had just installed the OS X 10.10 Yosemite on my Dell Inspiron 15R (N5150) laptop. I just got enabled the ATI Mobility Radeon HD 5650 through CLOER injection. However, my laptop is running with very low brightness. How to enable the brightness control in Sys Pref==>Display? Kindly guide me to enable the brightness slider on my laptop. I had attached my DSDT here.

Thanks In Adavance,
Jithin Chandran

No. The guide is for Intel graphics as is stated in the post.

According to your profile, all your systems have Intel graphics.

I have no experience with Radeon...

Hi RehabMan,

You probably need a different patch. Search for a different one or patch it yourself.
