Bug Description
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.
Steps to reproduce:
1. install system with trusty
2. install fglrx
3. sudo amdcccle
Expected result:
Able to see the optoin of switchable graphics
Actual result:
There is no such option.
Verification:
1. Adding "nogpumanager" to kernel parameter
2. Recreate the xorg.conf with "amdconfig --initial".
3. Reboot
4. Open amdcccle
You will able to see the option of switchable graphics
