I have disabled gdm3 automatically loading at startup.

Now from a cold boot the boot splash image (dell in this case see image) persists. The laptop is active and I can SSH in. I can enter console as normal and then login.

How do I finish booting into console awaiting login? This is stopping the laptop blanking the screen and entering display power-save mode.

Edit: Actually Ctrl + Alt+ F1 etc don't open TTY1 either, I've broken something at startup it appears, but I am still able to SSH in.

journalctl -b returns this at the end which stands out to me

Here is the full boot log if anyone can point me in the direction of where I should investigate: https://paste.ee/p/oiDxG

  • Re-enable gdm3, and then tell us what your ORIGINAL problem was. BTW... it looks like you've got a defective LCD display panel. – heynnema Apr 19 '20 at 17:36
  • I disabled it with sudo systemctl set-default multi-user.target

    Do you want me to enable it with sudo systemctl set-default graphical.target

    The laptop hasn't used a gui from the beginning. Its desktop install with gui autostart disabled.

    I have recently tweaked the blank and powerdown values with setterm and added that as a service. See here: https://askubuntu.com/questions/1228271/how-do-i-enable-a-timed-laptop-screen-power-off-from-the-console

    So it could be that, but it was working yesterday.

    Ha, the LCD is defective, this will be a headless test environment.

  • I'm sorry. It looks like you've hacked your system too much, so I can't help you, other than suggest you do a fresh install, and then ask for help if you need it. – heynnema Apr 19 '20 at 17:55
  • Seems a bit extreme to have to fresh install when everything works whilst im SSH'ed and all services I want still run! – randomlyalex Apr 19 '20 at 19:14
  • You've disabled gdm3, you've written system .services, you've chmod'd parts of your system, you're getting PAM errors and "/etc/securetty: No such file or directory" errors. How are we supposed to support this? – heynnema Apr 19 '20 at 19:44
  • Everything i've done is in your comment and that other linked question! But I get your point. I'll search plod away myself for a bit. It's to do with my last question (can you help with that, is what I did right/wrong there?). This only happened after a reboot overnight since that. Boot.log is here (https://paste.ee/p/oiDxG) just in case you have any ideas, no worries otherwise :) Something has tied the console up on boot that doesnt let it release to show login. *I think. – randomlyalex Apr 19 '20 at 20:33
