Both GPUs are used by default. If you attach your /etc/X11/xorg.conf and /var/log/gpu-manager.log we can see what's going on.
In any case I wouldn't expect to find any options in the AMD panel to switch between the two GPUs. That's only available on Intel+AMD systems. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1315285 Title: [AMD Richland + Mars] Unable to switch graphics Status in “fglrx-installer” package in Ubuntu: New Bug description: Unable to switch in between APU and Discrete GPU.
