I am a new linux user  (distro : Linux Mint 18.1 Serena) I am using an AMD a10 7800 processor. I installed the driver which I downloaded from the official site (fglrx-15.302) , but it made me unable to boot the system(black screen after showing the logo ) and I had to uninstall it, so is there any way I could install the right  driver to my GPU?
