Discard all the hidden .Xauthority files in your user account and try again?
I'm sure you probably know this but the closed-source driver cannot be
shown to be rt-kernel safe because the source is hidden. I was having
similar problems in a machine here - upgrade to new xorg-server and
things that used to work didn't work anymore - but I attacked the
problem a different way and bought a $40 nvidia 6200 card from NewEgg
that works well with the open source driver. Everything was fine and
we got better performance than before.
Just a thought.
