test vga_switcheroo patch for nouveau

**Instructions for testing the patch**

Upgrade xorg/nouveau and the kernel from xorg-edgers:

sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update && sudo apt-get dist-upgrade

Install kernel 3.2. The current version is 3.2.0-5:

sudo apt-get install linux-{image,headers}-3.2.0-5-generic


Reboot


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
