I'm trying to figure this out, but it seems odd, when I plugins installed the screen on my Octodash goes green. It seems if more than 1 plugin is enabled, the screen goes green.
I'm running Rpi 4 Model B, with Hyperpixel 4 screen. Everything has been updated to latest version as well.
I went trough the octoprint.log.
At the very start, the Octodash plugin is activated. While the rest (25 times) it's deactivated.
During the first start that plugin has problems to get the settings loaded due to a missing file.
but the issue, it doesn't matter which plugin, if there is more than 1 running, I get the green screen. I've tried loads of combinations, and it doesn't matter.
Here is the latest with with Obico and Octorelay only running.
Because the hyperpixel runs from GPIO pins you can't really use any of the other GPIO plugins along with it. Disable any GPIO plugins and I bet your issue is resolved.
