Ubuntu was working with default mesa graphic drivers. I tried to install nvidia driver for my geforce gt650m. I installed different versions of nvidia 319, 310, etc. All of them installed but my entire UI system crashed. Now my login screen looks so small, i don't have desktop or unity.

I am running 13.04.

My story about the Nvidia drivers: At first apt-get install nvidia-current, removed it later.

Then i just downloaded nvidia 319 310 313 different versions with wget stopped gdm and just run ./NVIDIA

So you have Optimus-CUDA graphics card with Geforce GT650M ?

Here is a good (off-topic) - link - but there is anything explained:

nvidia-frickle with hybrid chipset is now over finally?

You need this package as driver :

CUDA SDK 1.1 Beta for Linux

You find it between center and below at "Download" - Link :
