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.

^{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?

Solution 1:

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

type:

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

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

change:

#WaylandEnable=false

to:

WaylandEnable=false

Then reboot.
