[Launchpad Bug Tracker <1410801@xxxxxxxxxxxxxxxxxx>]

This bug was fixed in the package ubuntu-drivers-common - 1:0.2.91.10

---------------
ubuntu-drivers-common (1:0.2.91.10) trusty-proposed; urgency=medium

  * gpu-manager.c, gpu-manager.py:
    - Use the amdconfig tool to configure multi-amd PXpress. This
      fixes a problem where the AMD control panel won't show an
      option to switch between power saving mode and performance
      mode on AMD+AMD hybrid systems (LP: #1410801).
    - The tests now reflect a more relaxed approach so that we
      do not overwrite configurations that are not supported (such
      as multiple xscreens set in the xorg.conf).

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
