I am a great fan of DietPi running it on multiple SBCs.
I am wondering if there is a way to put the original Raspberry Pi display to a good use.
Background: I have a Raspberry Pi 4 sitting on my desk, being located in a case that also holds the original Raspberry touch display. It is only connected via ethernet, no mouse or keyboard attached.
This raspi does serve me as Gitea server. Currently the display shows the default login prompt ("Press return to login").
Is there a way
a) to disable the display by software (NOT disconnecting the cable

b) to show useful information (system load from NetData, stats from Gitea, etc.)
on this display instead of the login screen?
Any ideas welcome.
