I have a Radeon 7950. Here is the fglrxinfo:

display: :0  screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: AMD Radeon HD 7900 Series
OpenGL version string: 4.2.12002 Compatibility Profile Context 9.012

I am using fglrx-updates. I set up via amdcccle my two monitors for multi-display. But when I boot, my second screen is black. I hover my mouse over to it and my mouse cursor appears. I can even click on where the Unity bar would be and it launches programs. The problem is that nothing shows but my mouse pointer.
