Feedback: Works on Macbook Pro 5,1 #42

FYI your gpu-switch script works as expected on a Macbook Pro 5,1. Should not be surprising given it has the same exact video hardware setup as a Macbook Pro 5,2.

One thing that would be really helpful on your README file is a note on how to figure out which GPU you are currently using.

I found this helpful: https://unix.stackexchange.com/questions/16407/how-to-check-which-gpu-is-active

So in my case I documented this note for myself:

Find out which GPU you are currently using
    glxinfo|egrep "OpenGL vendor|OpenGL renderer"
    glxinfo | less # Look for the "Extended renderer info" line.
    --
    "Device: NVAC" = 9400M (Chipset/onboard GPU)
    "Device: NV96" = 9600M GT (Dedicated chip GPU)

Thanks for your script.

Ha, happy to hear that!

Does the windows version also work? Update: For Windows7 it doesn't (The procedure entry point "setFirmwareEnvironmentVariableExW" could not be located in the dynamic link library kernel32.dll)

Is your Windows installed using EFI? It won't work in BIOS mode.

Two comments: 1) After hours of attempting to hack a means of changing the default boot GPU for my Macbook Pro 5,1 from integrated to discrete, I found your script, and it worked perfectly. I am running SparkyLinux Gameover Edition with the Nvidia 340xx legacy drivers. I don't even need a xorg.conf once I selected the discrete card with your script. 2) Thank you. Thank you. Thank you. :smile:
