I'm running Raspbian Buster with no Xserver but attached to a television. I have a script that writes an image to the framebuffer from a timed systemd service.
The problem is /dev/tty1 is writing its blinking cursor (with black character sized box) that appears over the image. I would like to prevent /dev/tty1 from writing to the framebuffer in a safe manner. I suppose if I lose SSH access I would need to use /dev/tty1 to recover machine.
