-=- Then I did
rpm -qa | grep x11-drv

xorg-x11-drv-ati-19.0.1-1.el8.x86_64
xorg-x11-drv-dummy-0.3.7-6.el8.1.x86_64

So, the old el7 driver still there - good and bad since could be the 
source of my problem.

modprobe radeon
modprobe: FATAL: Module radeon not found in directory 
/lib/modules/4.18.0-147.3.1.el8_1.x86_64

Then I removed ALL .el7 rpm installed that still was left - which meant 
a lot of .el8 rpm uninstallations and reinstallations.
