--- Comment #2 from Arvin (arvin.kebob@gmail.com) --- I can confirm I have a similar issue on a laptop with AMD dual GPU (6520G + HD 6750M). The system boots to a graphical desktop (MATE + LightDM) and works fine until I open a program with the discrete graphics (DRI_PRIME=1).
Going to bisect once I get the laptop later in the day.
