Best distro for NVIDIA Optimus or guide for Ubuntu

Now i use Ubuntu GNOME 13.04 + Git update (xrand 1.4 and xorg 1.14.0) + Kernel 3.9.0 + NVIDIA 319.17 WHQL.

But on my Asus UX51VZ (CM062P) with NVIDIA GT650M + HD4000 the backlight not working, battery from 4h in Win to 2.30 in Ubuntu and the FN keys don’t work.

Can suggest me the best distro for use nvidia optimus? Linux or BSD (no Windows)…
Or an updated guide for the kernel 3.9.0 and NVIDIA 319.17 WHQL with Ubuntu?
Can i install 319 in Ubuntu without kernel 3.9 or git update?

I need to use Optimus and backlight, brightness, FN Keys and battery (min 4h)…can help me???

I believe the Fn keys not working is a bug in the NVIDIA driver itself. So if you don’t want to deal with that, I believe you’re stuck with Bumblebee for now.

Try this
Change the line:
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash acpi_backlight=vendor”
in “/etc/default/grub”
type “sudo update-grub” in terminal and reboot

I tried it in ubuntu 13.04 and no luck. But it works in ubuntu 12.04 for me.
