AMD Radeon R7 don't work on Ubuntu 16

You should already be using the Radeon or the AMDGPU by default.
As far as I know, the A MDGPU driver support for some R7 cards is 'experimental', only the R9s have full support.
R7 cards are in a strange place right now.
You might end up waiting until Canonical updates the situation.
