Add option to suppress terminal output on display (if present) #2791

Closed k3wals closed 1 year ago

k3wals commented 4 years ago

I was able to suppress the terminal output to a display by commenting the following lines:

//supervisor_start_terminal(width, height);

within:

It would be convenient to disable the terminal display output in boot.py perhaps.

Blinka icon is still present though momentarily.

@dhalbert suggested I open an issue after discussing on Discord.

So it looks like I am not able to sleep with the backlight off unless you have another suggestion to try.

Please open a separate issue for this.

Closing now that the root_group can be hidden.

note for posterity ...

Using board.DISPLAY.root_group.hidden = true does not prevent a board level ePaper from refreshing on REPL.

After displayio.release_displays(), there is still a blinka flash when networking seems to be initialized.

  • boards without board.DISPLAY cannot do this. For example, matrixportal s3 does not have board.DISPLAY.

After displayio.release_displays(), there is still a blinka flash when networking seems to be initialized.

Facing this exact issue using a MatrixPortal M4. Any ideas on how to get rid of the blinka flash anyone?
