[Phoronix] Hybrid Graphics Comes To Linux In Crude Form
David does know how to power-down the Radeon GPU using ACPI and for the Intel GPU to potentially put it in a suspended state, but that code is not found in today's patch called the vga_switcheroo. Lastly, David is also going to lobby the GDM developers to have a log-out button for GNOME that says "Switch GPU" to provide a bit more transparent experience without having to manually change run-levels and write to the debugfs switch.
