Using nouveau doesn't imply the card will always be on= . Assuming the firmware on the device turns it off and on, vga-switcheroo o= r bbswitch will send the proper ACPI commands to turn it off and on. When i= t is on the chosen driver will be used.

I used bumblebee for quite a while.=C2=A0 It worked okay, but every = upgrade I
would have to fiddle with it again.

I switched to the Nouveau driver and I'm very glad I did.=C2=A0 "C= onventional
wisdom" says Nouveau quality is lower than Nvidia, but I found it work= ed
better on some things (Second Life).

As someone else pointed out, with Nouveau the GPU remains on all the
time consuming power.=C2=A0 This is the downside.

If ease-of-use and/or open licensing are more important to you than top
rendering quality and power consumption, consider using Nouveau.
