I also looked in the /boot/overlays directory and piscreen2r is there

I ran lsmod

which showed that fbtft was there but not piscreen2r (not sure it it shows overlays?)

I boot the PI in console mode and nothing comes up

what does happen is I get /dev/fb1  with an LS that I did not before

crw-rw---- 1 root video 29, 0 Nov 10 13:18 /dev/fb0
crw-rw---- 1 root video 29, 1 Nov 10 13:18 /dev/fb1

I will go backand look at the piscreen doc to see if there is anything else to try
