Why black screen and no sound?

Question

linux

When booting ubuntu after the menu is rude, just a black screen hangs and tightly. It really helps to start with the nomodeset parameter in the rough, but I can't boot all the time like that ... I'm sure that some drivers are missing, but I don't know what to put. And I also discovered after starting that there is no sound at all. No matter what I run, there is no sound. It is also possible that some drivers are missing. I just installed the system.
PS Kubuntu 16.10, AMD Radeon R7 200 Series graphics card.

Good morning.
Install Kubuntu 16.04 to get started . *ubuntu *.10 versions have a short support period, and *.04 versions have five years. In your case, support for kubuntu 16.10 will end in July of this year.
Then configure like Ubuntu 16.04
