As,is working now. But
- I have tried to install amdgpu-pro-17.10-410326.tar.xz on Kubuntu 17.04 and it doesn't work.
- But it works on Kubuntu 16.10
Now, I think the main problem is Linux Kernel. amdgpu-pro-17.10-410326.tar.xz only works on Kernel 4.8.x, but not on Kernel 4.10
And one more thing, AMD Pro driver is necessary for
- Blender GPU rendering
- Installing and Running Games from Steam
Default opensource drivers are not enough
