Run nvidia latest driver on 12.10 Unity crashed

You have a switchable video chip and this doesn't work well at all in Linux. I have never seen a success story with this mess and it is best avoided. This link may help:
https://help.ubuntu.com/community/HybridGraphics

Using the Edgers PPA is not advised for casual use, it is highly experimental and very very unstable.

I run this command :-

sudo lshw -C display; lsb_release -a; uname -a; dpkg -l | grep nvidia

Output as per below:-

bob@G5047:~$ sudo lshw -C display; lsb_release -a; uname -a; dpkg -l | grep nvidia
