Need to post the following information on your computer as per AMD Forum rules : INFORMATION REQUIRED WHEN POSTING A QUESTION.
It seems like there are no Linux drivers for Laptops. Only Desktop. But I found someone that does provide Linux Drivers for the R5-M430 AMD Card here: graphics - Installing Oibaf's Drivers for AMD R5 M430 on Ubuntu 16.04 - Ask Ubuntu . Did you laptop come with Linux installed?
It from Oibaf Driver. Never heard of them. But the OP says it works. Following the above links, found the Oibaf Driver download page here: Updated and Optimized Open Graphics Drivers : Oibaf
This is AMD Linux Driver but I don't see your GPU mentioned: AMDGPU-PRO Driver for Linux® Release Notes
