Switch to my AMD RADEON graphics Topaz XT in Ubuntu 16.04

In About this Computer I see:

Graphics: Intel® HD Graphics 520 (Skylake GT2)

But I have got hybrid graphics. I have external AMD Radeon TOPAZ XT graphics card. How can I make it work in my Ubuntu 16.04.2 LTS.

I am trying to use VGA Switcheroo, can someone tell me what commands should I add so as to make the dedicated graphics work?

Also I tried to install amdgpu-pro graphics driver but it made my screen go blank. So I had to uninstall it.

Open up Synaptic package manager and install the xserver-xorg-video-radeon package. Reboot your computer. You should automatically be switched to your Radeon card, however, you should check your additional drivers menu to be sure the switch was made.
