Hi folks.. Nividia posted a beta driver for us....
Did this -
copied the NVIDIA-Linux-x86_64-302.07.run to the home folder
opened a terminal
sudo stop lightdm = stop the X-server
ctrl - alt f1 or f2 through f6 to start a terminal
did a dir to see it is there; then typed; sudo sh NVIDIA-Linux-x86_64-302.07.run
need to be root
exited; rebooted; now typing this from Unity - bit slow but it works
well sofar not having done much; everything? in firefox works
P.S. I did the upgrade path adding the NVIDIA-Linux-x86_64-295.40.run driver then the above...
If you did the " nouveau" driver route you will need to a more complicated set of instructions..
