That is a excellent walk through on how to get the amd gpus working...and we have confirmation that it works. I, alas, have upgraded all my machines to 20.1 and am using kernel 5.4.0-66. I might try reverting to kernel 5.4.0-26 and give it a try on a 20.1 machine anyway or I could just do a dual boot 20.04 install. I might give this a try after the TN-Grid challenge. Thanks Z and mindcrime.
