Steps: 1. Install 14.04.1 + fglrx, reboot 2. Make sure that the system is now using the discrete GPU, and switch to the integrated GPU by using the amdcccle, reboot. 3. Make sure that the system is now using the integrated GPU, and switch to the discrete GPU by using the amdcccle, reboot. Expected result: * Could switch between these two GPUs without any problem. Actual reuslt: * After step 3, amdcccle is gone, and from the unity_support_test indicates that it's still running with the integrated GPU ubuntu@201305-13637:~$ /usr/lib/nux/unity_support_test -c -p OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile OpenGL version string: 3.0 Mesa 10.1.3 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes Compiz supported: yes If you run the amdcccle from /usr/lib/fglrx/bin/amdcccle, it will tell you that the driver is not installed or it's not functioning.
