OpenNeptune and display_connector not working

[dsrdakota]

So far I have the latest version of everything installed.
OpenNeptune - latest
display_connector - latest (had modified a few files to get pillow working, ie. some python wheels and modules had to be updated)
display_firmware - latest (tried running display_connector service with stock/oem screen firmware and ON custom firmware)

I am running the latest versions of klipper, moonraker and fluidd. I have the Neptune 4 Pro.
Here is a sample log with custom firmware.

I updated several......modules? and am now also having issues with my display not working. It shows a continuous loading Elegoo logo. I am NOT by any stretch of anybody's imagination a dev or programmer. I am getting moonraker warnings of an invalid path along with three unparsed warnings that I assume are related to the file it can't find.

Not sure where else to go to look for advice. Thanks in advance.

Had the same problem after klipper / moonraker update today. This resolved my problem:

• SSH into the printer
• go to directory: /home/mks/display_connector
• run script: ./display-service-installer.sh
• enjoy ;-)

[Damon20r]

Thank you! I'll give that a try.

[Damon20r]

It worked like a charm. Thanks a million! I just need to stop updating it because every time I do it seems like something screws up. That's the reason why I am now using a P1S.
