** Description changed:

+ SRU Request:
+
+ [Impact]
+ Hybrid graphics systems with the AMD+AMD combination will not have an option to switch between power saving mode and performance mode.
+
+ [Test case]
+ 1. Install 14.04 and the fglrx driver on a hybrid (laptop) system with two AMD GPUs
+ 2. Reboot the system
+ 3. Launch amdcccle and see if there is an option to switch between power profiles
+
+ Expected result:
+ * There should be an option to switch between power profiles
+
+ [Regression potential]
+ Low, as the change in gpu-manager only affects the codepath that deals with the above mentioned hardware combination.

This is a trusty system with two GPUs:
00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Richland [Radeon HD 8610G] [1002:990f]
01:00.0 Display controller [0380]: Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260] [1002:6900]

After installing fglrx driver, still not able to swtich in between
graphics.
