Fix: Missing Unity Desktop After Installing ATI/AMD Drivers Ubuntu 12.10 / 12.04

I got my new PC with Radeon HD 7850 GPU. After installing AMD drivers, my PC was booting with no unity. Only thing that I can see is a scrolling mouse.

But now I fixed it easily.

What causes this problem?

AMD Drivers on Ubuntu repository is not supporting new x.org. This making unity desktop crashing.

How to fix it?

1- Uninstall old AMD/ATI Drivers. How? Follow here.

2- Open terminal and install these packages with this command:
"sudo apt-get install build-essential cdbs dh-make dkms execstack dh-modaliases linux-headers-generic"

3- If you are using 64 bit version of your distro, install this too.
"sudo apt-get install lib32gcc1"
4- Install drivers and reboot.

Now you got Unity desktop without problems with AMD drivers.
