I have upgraded from Ubuntu 16.04 to Ubuntu 16.10 (Linux 4.8). After the upgrade, my screen turns and stays black on booting.
I tried the advanced option to run Ubuntu 16.10 on Linux kernel 4.4 and it works.
I know that fglrx is no longer supported since Ubuntu 16.04, so Ubuntu has been using the open source version (xserver-xorg-video-radeon).
My question is that how can it work in Linux 4.4 but not 4.8 (both are Ubuntu 16.10)? and how to solve the issues to make it work on Linux 4.8?
Thank you
Edit 1:
This question is not duplicate as indicated by many. In my case, I can boot on Linux kernel 4.4, but not 4.8.
