Good staff …
I’m trying to install the NVIDIA drivers on my Ubuntu 14.10, but several things happen …
1st is too slow (I do not know if it is normal, I have a good machine)
2º- when it reaches the end of the installation gives error
Can anyone help me?

Be well …

Why not just install the driver from the Ubuntu repos?
