It worked for a while, now I get epd errors. No idea what changed. Have reinstalled and rebooted. #64

The display worked fine for a few hours after I set it up and installed using the automatic install.

Then for some unknown reason (nothing changed as far as I know) I can't do anything, and everything results in the error message below.

Just to repeat, everything worked, and I could use the clock and write and draw commands. Therefore the interface SPI was switched on and epd/fuse/whatever was present on the system.

Error message:

sudo papirus-write "foo"
Traceback (most recent call last):

Needed to run papirus-config again for some reason to activate the EPD.

You could also try sudo papirus-set 2.7 or whatever the screen size is next time that happens too
