**Instructions for testing the patch**

Make sure very thing is up-to-date and you use kernel 3.2.0-5:

sudo apt-get update&&sudo apt-get dist-upgrade

sudo apt-get install linux-image-3.2.0-5-generic



Make sure you upgrade xorg via the PPA (under Ubuntu):

sudo add-apt-repository ppa:xorg-edgers/ppa

sudo apt-get update && sudo apt-get upgrade



Apply the patch against the sources of the current kernel version:



apt-get source linux-image-$(uname -r)

cd linux-*

cp /usr/src/linux-headers-$(uname -r)/Module.symvers .

make oldconfig && make prepare && make scripts

wget http://lekensteyn.nl/files/nouveau-switcheroo-optimus.patch

patch -p1 < nouveau-switcheroo-optimus.patch

make M=drivers/gpu/drm/nouveau



Load module dependencies, unload old, load new:

sudo modprobe -v nouveau

sudo rmmod nouveau

sudo insmod drivers/gpu/drm/nouveau/nouveau.ko



Make the module work across reboots:

sudo cp drivers/gpu/drm/nouveau/nouveau.ko /lib/modules/$(uname -r)/kernel/drivers/gpu/drm/nouveau/

sudo update-initramfs -u



This won't persist between kernel upgrades, for that use DKMS
