With Linux Mint 18 and KDE Neon the bug changes from random to boot up. It
happens the first time from a cold boot. After a restart, which means
screwing up my hard drive and holding the power button. Then turning it on
and the black screen comes back.

I' am very fustrated like Brian. Canonical doesn' t need AMD to repackage
the driver for the new X Server. Abandoned by AMD and the commercial
distros. Do not advocate AMD, they must have known this problem and ignored
it.
