How to use Hybrid Graphic Switch on Sony Vaio Z?

Question

I got it to install nicely and it's all working, but I don't know which graphics card is being used nor how to switch between. I tried installing the official Nvidia drivers, but then I could not boot up my computer afterwards so I have not installed them again after doing a reinstall of Ubuntu.

PS, if you have a grub install failure during install, the key is to tell it where to install the bootloader at the very beginning of the installation, on your partition selection screen (choose dev/mapper, not the /dev/sda it defaults to).

Solution

The quick answer is that you can get both graphics cards to work, but you will have to reboot to switch between them. Also, from the little googling I did, it looks like a royal pain to set up right now. (see link) Probably in a year the process will be nice and smooth, but right now its pretty messy.
