MacBookPro11,3 - No supported Nvidia graphics adapter found

[cstrahan]

I'm having some trouble with my brand new Retina Macbook Pro.

I wrote and applied the following patch:

And here's some debug info:

Any idea whether nvidiabl should work with my model? And if it should, any idea what's going wrong here?

[cstrahan]

Oops! I thought I had the latest release. So, I built with 0.87, and now /sys/class/backlight/nvidia_backlight is registered, but trying to manipulate the backlight has no effect.

Hmmm... I wonder if this is a conflict with apple_bl. I can't seem to blacklist the module - perhaps that because apple_gmux depends on it? (I'm now a bit out of my depth here when it comes to kernel modules).

[cstrahan@nixos:~]$ lsmod | grep gmux
apple_gmux              6243  0 
apple_bl                3048  1 apple_gmux
video                  11692  1 apple_gmux

From looking at https://wiki.archlinux.org/index.php/MacBookPro11,x, it looks like all I need to do is run:

setpci -v -H1 -s 00:01.00 BRIDGE_CONTROL=0

Looks like I won't need nvidiabl in my case.
