I downloaded this one: Radeon™ R9 200, R7 200, HD 7000, HD 6000, and HD 5000 Series. Build aborted with errors. Binary installation was okay, but xorg was not working at all after installation, even with vesa config. After a couple of minutes searching all installed files I was lucky to find the uninstall script. After removing all ATI files from my Linux xorg now works, but Xinerama does not. Will the proprietary driver enable usage of Xinerama?
I found this as I'm researching the possibility of upgrading my Linux Mint installation to LM 18 (Sarah) - based on Ubuntu 16.04
Is this web article accurate, claims latest AMD proprietary driver 15.302 *works* in Linux Mint 18 (xorg 1.18)
