I'm running a Raspbian Buster server with no Xserver. I want to display wallpaper on a connected television but /dev/tty1 keeps over writing /dev/fb0 either with a blinking cursor or just refreshing randomly 60 seconds later after I make the cursor invisible (from getty@tty1.service). My new strategy is to completely prevent /dev/tty1 from ever writing to the framebuffer.

Thanks for any help.

  • Is there any reason that you can't just use a X server or Wayland server? Which will handle tty problem for you – 炸鱼薯条德里克 Aug 13 '19 at 1:19
  • I'd prefer to avoid the overhead and I'm testing writing images to the framebuffer directly. – deanresin Aug 13 '19 at 1:21

    @mosvy interesting. I think I will test your idea soon. But I have solved my problem I think by disabling the getty@tty1.service and then making tty1 cursor invisible. It seems to be working. – deanresin Aug 13 '19 at 2:08

    The problem with disabling that getty@tty1.service and no cross-over serial cable around is that you may not be able to access your device if ssh or anything else goes wrong. – mosvy Aug 13 '19 at 2:11

    If something goes wrong you can always boot recovery mode from grub and get an emergency shell. – Rafael Kitover Aug 13 '19 at 18:26

To stop /dev/tty1 from overwriting the buffer I'm using

systemctl stop getty@tty1.service and then make the cursor invisible with..

/usr/bin/tput civis > /dev/tty1

This allows me access to console after reboot should I lose access via ssh.
