Ubuntu – Gdm3 display manager hangs after booting with Ubuntu 18.10


I want to use gdm3 but unfortunately, it does not work. After booting it just completely hangs.

enter image description here
boot process stopped after Started GNOME Display Manager

It just does not do anything. Installing lightdm and activating it via sudo dpkg-reconfigure lightdm does work but then again that's not what I want.

I tried several things already:

  • Reinstalling NVIDIA drivers
  • Changing my run level to multi-user.target
  • Using update-rc.d -f gdm3 remove && update-rc.d gdm3 defaults to reconfigure gdm3
  • Installing the packages that I need sudo apt-get install ubuntu-gnome-desktop gnome-shell gnome
  • Reinstalling gdm3

Does anyone know how I can get gdm3 to work?

Not sure if this is going to fix your problem, but it's quick, so it's worth a try...

You may have a problem with an older computer, with an older GPU. Try this...

  • boot to recovery mode
  • choose root access


sudo mount -o remount,rw /      # to remount the disk r/w

sudo pico /etc/gdm3/custom.conf # edit this file





Then reboot.
