This is an ongoing issue with the nouveau driver.  I finally gave up and
went with radeon.  The open source radeon driver has been rock solid
for me, and meets my simple needs.  AMD / ATI released the specs
for the radeons, unlike nvidia, where the devs are reverse
engineering the nouveau driver.  Here's the nouveau bug.

A thought, did you fully remove the nouveau driver before using the
nvidia binary blob?  They don't play well together, and it can cause
problems.

Did you use the akmod / kmod from rpmfusion to install the nvidia
drivers?  

Finally, I think I've seen something about nvidia not having their
binary blob modified to deal with the changed X api in f23.  That could
be the source of your problem with the binary blob.
