Nope, just don't forget to add the acpi_osi= parameter to GRUB either with  
sudo dpkg-reconfigure grub-pc or by manually editing the /etc/default/grub  
file, which prevents the use of both GPUs at the same time (and should save  
you battery power). You will be then able to switch the default driver using  
the sudo update-alternatives --config x86_64-linux-gnu_gl_conf command, in  
case you'll choose to use the proprietary NVIDIA driver later.
