AMD & 13.0 Current

Mon Sep 16 02:06:00 UTC 2019

I wanted to add that when I installed this weeks 13.0 snapshot, I tried it
first with only the kld_list="amdgpu" in /etc/rc.conf AND NO
/boot/loader.conf entry. It failed to load startx. I then made the
loader.conf entr, rebooted and startx loaded x windows, the nice little
screen with 3 xterminals and a clock.
