I'm not shure if the prime kernel implementation with 3.13 does
the same.
I never test it because of missing Guides, and it is only for the nouveau
driver.
But the bbswitch mod is very useful for users like me, whose only watching
hd-videos, using compiz on a notebook and don't play games.
For this profile i don't need the discrete nvidia card. The integrated intel
card does his job well for this case and it is pretty useful to switch off the
discrete card to decrease power consumption.
Starting with 3.12, you should have the discrete card already off with stock
Fedora components (Nouveau, Radeon, Intel, Mesa).
Just check the content of /sys/kernel/debug/vgaswitcheroo/switch, you should
see "Off" or "DynPwr" for the discrete chip.
