I have two RPi3s with Raspbian Stretch - one with RS Full and one with RS Lite. I have enabled autologin and our custom plymouth splash screen with "splash quiet" in /boot/cmdline.txt.
Now I want to do same behaviour on RS Lite. I installed X server and Plymouth, added same settings in /boot/cmdline.txt. Everything works ok except one thing - when boot splash appears, the "autologin" message + MOTD is written over this plymouth screen. This does not happen on the other RPi.
Also, I can notice that on RPi "full" boot console is on tty1 but X server starts on tty2. RPi "lite" starts everything on tty1.
Is there any specific settings that could influence this behaviour and I forgot about it? Why RPi "lite" displays the console output over the splash screen, but the other RPi does not?
