Ubuntu – Ubuntu 18.04 is stuck at loading screen after new installation

boot

I installed Ubuntu 18.04 from a bootable USB last night, but when I tried to login to the operating system I got stuck at a ubuntu loading screen with five dots on it.

enter image description here

I have seen an older question where it might seem to be a graphics problem, and the solution mentioned was to press Ctrl +Alt+f1,f2,f3 etc. to go the shell, but when I do that the shell is not showing up.

What else can I try?

  • Ubuntu 18.04 uses Wayland display server which does not work on a few systems.

    Try the below steps to make the system boot normally:

    1. Go to recovery mode from the GRUB menu and then boot into the system. Recovery mode uses low graphics and hence will not get stuck at the splash (logo) screen.
    2. Once you are logged in, open a terminal (Use Ctrl+Alt+t shortcut)
    3. Try changing the display server to Xorg in the gdm3 custom conf file using the below command and reboot the system.

      sudo gedit /etc/gdm3/custom.conf
      
    4. Change #WaylandEnable=false to WaylandEnable=false (Basically uncommenting it).

    5. Reboot the system.

    This will disable the Wayland display server and make the system to use the Xorg display server. Your system should hopefully progress to the login screen now with a normal boot.

    Let me know if this works.
