If the laptop has a dual hybrid-GPU setup, things might be a bit more complicated to setup. I was trying to follow all the guides to setup the dual hybrid GPU on my wife's laptop using Debian/Ubuntu and none of them worked. Then I figured out that there are multiple ways that the dual hybrid GPU might be configured on the laptop. For instance in my case, it was always the intel GPU that was exposed to the OS and all the intensive graphics work, the intel GPU offloaded it to the AMD discrete GPU and then rendered the result. So installing a fairly recent version of kernel (Debian Jessie) and enabling just the intel GPU first before installing the radeon driver solved the problem for me. So you might have to do some research before trying the various howto guides. If you don't understand any of the terms I have used, please feel free to search for them and read up.
