I'm a long time Ubuntu user. I've used my current computer (Asus Zenbook UX32VD) with 12.04 and 12.10, using bumblebee when needing the nvidia card, but defaulting to intel for better battery life.

Now I've just installed Ubuntu 13.10 (gnome flavour), and realized, that Saucy boots up using the nvidia card with nouveau driver by default. This reduces my battery life from over 4 hours to just 2.5 hours. I'd like to switch this behavior back to what it has been, i.e. default intel, nvidia when needed. The problem is, i don't know how to do it. Can anybody here help me out?

tia, juhis
