There are two ways to switch between the AMD v-cards with fglrs driver:

  1. Use 'aticonfig' command with one of the options under your root:

--px-dgpu Activate discrete GPU (High-Performance mode), must re-start X to take effect

--px-igpu Activate integrated GPU (Power-Saving mode), must re-start X to take effect

  1. Run 'amdcccle' under your user account and choose the v-card you want then re-start X-server.
