Hi,
I'm using Arch on a Lenovo Z370 which has both the integrated sandybridge graphics chip and a Vvidia 410M GPU. In Arch I don't need the Nvidia GPU at all since the Intel chip can play 1080p videos, which is the most I need on Arch.
I found a promising project here.
I used it on Ubuntu before, but it won't build under Arch. There is something wrong in the makefile.
make -C /lib/modules/2.6.38-ARCH/build M=/home/axle/acpi_call modules
make: *** /lib/modules/2.6.38-ARCH/build: No such file or directory. Stop.
make: *** [default] Error 2Now I'm not that much of a linux programmer, and would appreciate it a lot if someone could tell me what I have to change in the makefile to get it to work in Arch.
Greetings, pixle

First of all, welcome to Arch Linux forums..
From what I have read about optimus technology, it was not supported in Linux, until a few days ago. Both graphics card would run simultaneously at full speed eating your power/battery.. There was no way to disable one of them or even get the nvidia card to work.. Even nvidia themselves released a official statement saying they will not be supporting optimus on Linux
You are in for luck actually.. Recently somebody, with a lot of hard work has released something called bumblebee which promises support in linux for nvidia cards using optimus technology..
Here is the homepage for bumblebee - https://github.com/MrMEEE/bumblebee
Here is more info - http://www.martin-juhl.dk/2011/05/optim … em-solved/
This still doesn't help you turn off the nvidia driver (or the intel one) to conserve power.. But what it does is that it allows you to USE nvidia card on Linux.. Previously even that was not possible.. Apparently you can use this with nvidia official driver or the nouveau driver..

From my research, the acpi call to switch off the graphics card works for ATI discrete cards (in laptops where ATI discrete cards are present along with integrated onboard card, something similar to optimus in nvidia).. This does not work for nvidia optimus cards.. I could not find any nvidia optimus user who said this worked for him (and he was able to turn off the nvidia card)

Turning of nvidia with acpi_call work perfect for me with Optimus. You just need:
