As it says Ubuntu 16.04 has problem with fglrx driver, therefore I installed AMDGPU-Pro Driver. Even it was installed, seems like it is not working properly. When I navigate to 'Additional Drivers' section in Ubuntu there is nothing with AMD. I did this because system is very slow compared with other machines, and it is mentioned that this is because not having proper graphic drivers in hybrid systems.
As I found, one solution for this Driver problem is updating linux kernel to latest stable release.
How can I solve this graphic issue and speedup the system. Or is it okay to update the kernel?
Also I want to try OpenCL programming with AMD GPU, is it possible?
