fbcon is the framebuffer console.

This is the visible login prompt on the HDMI monitor.

How to get rid of it?

Kernel Re-Configuration

CONFIG_FRAMEBUFFER_CONSOLE=n

Need to rebuild (using bitbake) and re-install kernel.

Remove powerdown timeout

Kernel Re-Configuration

CONFIG_VT_CONSOLE=0

Linux commandline (boot)

vi /boot/cmdline.txt and add parameter

consoleblank=0

Wakeup framebuffer after powerdown

echo 0 > /sys/class/graphics/fb0/blank

Stop cursor blinking

echo 0 > /sys/class/graphics/fbcon/cursor_blink

... and clear framebuffer

cp /dev/zero /dev/fb0
