Thanks. :)  I find old files in /etc/modprobe.d:

-rw-r--r-- 1 root root  154 Nov 29  2016 amd64-microcode-blacklist.conf
-rw-r--r-- 1 root root   23 Apr 28  2011 i915-kms.conf
-rw-r--r-- 1 root root  154 May 15  2017 intel-microcode-blacklist.conf
-rw-r--r-- 1 root root   51 May 10  2014 modesetting.conf
-rw-r--r-- 1 root root  292 Aug  3  2012 nvidia-kernel-common.conf
-rw-r--r-- 1 root root  119 Nov 12  2013 oss-compat.conf
-rw-r--r-- 1 root root   27 Jan 19  2014 radeon-kms.conf

...I find radeon-kms.conf contains: "options radeon modeset=-1".  Is that
likely where my problem, or part of my problem, is coming from?
