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).
