How to test nouveau nvidia hybrid graphics switch on/off

One of the hybrid-graphics-linux launchpad team member kindly provided an Ubuntu
package for the patched kernel that reports "_DSM" vga_switcheroo switches for nvidia hybrid graphics laptops

(sub-arch is Core-Duo/Xeon, all other config options are based of
a stock Ubuntu kernel)
. You can download it at:


Please run this command post installing or
this kernel will fail to boot:

# mkinitramfs -k 2.6.35-rc5 -o /boot/initrd.img-2.6.35-rc5

So if you have a nvidia hybrid graphics laptop and want to test its nouveau drivers compatibility, now it's easier than ever...
