Why nouveau is used instead of Intel on a Intel-Optimus-Nvidia laptop?

I did a clean install of Xubuntu 15.04 beta 2 and all seems to worked
except of some apps having slow UI animations (like text scrooling in Kate,
slow rendering of Chromium UI, laggy YouTube in Firefox or Chromium). At
first I was thinking that instead of Intel it's running in VESA mode, but
after going to the drivers configuration app it turned out it was using
nouveau which is pretty much useless. And that's on a MSI GP70 laptop with
GT740M and i7-4700MQ.

I would suggest using Intel driver and GPU by default. It has an open
working driver and the GPU is good. Using nouveau means poor performance
and very bad initial experience.

I had to pick nvidia binary, then install primus, external
"prime-indicator", reboot, switch graphics and smoke-test that on 0ad (had
it installed, won't start if something is wrong with GPU config).
