Macbook 10.1 issue

Open mapringg opened this issue 10 years ago • 4 comments

I install gpu-switch correctly but after applying the fix the dedicated is still in used. Must I do something first to disable this and enable the intel card. I only have around 4 hr with the dedicated card.

Thank you

I only know how to disable the dedicated GPU under Linux (echo OFF > /sys/kernel/debug/vgaswitcheroo/switch).

I am not aware of any way of doing that under Windows to be more energy efficient. Maybe anyone knows a trick to do that under Window too.

Oh I'm talk about the Linux version. So I don't have to cd gpu-switch then ./gpu-witch -i ? Instead I should echo OFF > /sys/kernel/debug/vgaswitcheroo/switch ?

Oh. I only have the 11,3 Macbook Pro available und there you have to run ./gpu-switch -i and then reboot. The state of the selected GPU is stored in NVRAM and persist over further reboots.

After that you can switch off the dGPU with: echo OFF > /sys/kernel/debug/vgaswitcheroo/switch I hope this also works with the 10,1 model.

Ok I will give this a go. I guess I didn't echo OFF.
