No login screen after Ubuntu 18.04 update
After the upgrade from Ubuntu 18.04 to 18.04.1, when booting instead of going from grub menu to the purple login page, it goes directly to tty1.
The current kernel is 4.15.0-33 and I've already tried to boot with every kernel version from 33 to 29.
Also the systemctl status gdm3 command gives the active status.
Output of dmesg --level=err,warn:

First, eliminate a possible disk file system problem...
- boot to the GRUB menu
- choose Advanced Options
- choose Recovery mode
- choose Root access
- at the # prompt, type
sudo fsck -f /
- repeat the
fsckcommand if there were errors - type
reboot
If for some reason you can't do the above...
- boot to a Ubuntu Live DVD/USB
- start
gpartedand determine which /dev/sdaX is your Ubuntu EXT4 partition - quit
gparted
- open a
terminalwindow - type
sudo fsck -f /dev/sdaX# replacing X with the number you found earlier - repeat the fsck command if there were errors
- type
reboot
Next, eliminate a possible video subsystem problem...
At the GRUB menu, hit the e key, and edit the line that contains "splash quiet" to "splash quiet nomodeset", hit ctrl-x to continue booting. See if it will fully boot, even if the video display isn't at the correct resolution. If it boots, do one of the following...
1. Eliminate a possible wayland problem...
Boot to recovery mode, and choose root access. Then type:
sudo mount -o rw,remount /
In terminal...
cd /etc/gdm3# change directory
sudo pico custom.conf# edit this file
Find and change:
#WaylandEnable=false
To this:
WaylandEnable=false
Save the file.
sudo dpkg-reconfigure gdm3# select gdm3 DM
Select gdm3 and OK.
reboot# reboot the computer
2. Update/reinstall the current nouveau/Nvidia video drivers.
Update #1:
While trying the wayland fix, errors indicated a gdm3 problem. Reinstalling gdm3 resolved the problem.
fsck gives no errors, splash quiet is "quiet splash" in my file so I wrote "quiet splash nomodeset" and after ctrl+x the result is always the tty

While doing the Wayland part, doing "sudo dpkg-reconfigure gdm3" gives: "gdm3 is ruined or not completely installed". Edit: That message made me think and so doing this steps I've solved the problem! 1- reedit custom.conf leaving #WaylandEnable=false 2- rebooted in normal mode 3- from tty1: sudo apt install gdm3 That's it, maybe the update broke gdm3
