Yes, I enabled SPI.

I had to follow these instructions to get the screen to work, specifically these config updates:

Add a "#" in front of the line "dtoverlay=vc4-kms-v3d"

add this line at the end of the file " dtoverlay=piscreen,speed=18000000,drm "

(remove the double inverted commas "")

I will check the browser when I get home from work. But file manager, terminal, settings, everything else pulls up just fine.
