I experienced the same issue as Marcin described after updating from 14.10 on my Thinkpad T420.
In order to solve it I had to manually remove all nvidia-* packages and install nvidia-346. Not a big deal for anyone somehow comfortable with a shell but probably a show stopper for some other users.
Is there any mechanism to force using nvidia-346 when performing a distribution upgrade?
