I just recently installed Ubuntu 18.10. After successful installation, I rebooted my system but Ubuntu didn't boot, it gets stuck at showing started GNOME display manager.

My keyboard is also not working. What is the problem? How can I get a complete Ubuntu desktop ready without any errors?

  • @karel switching DM's may not be the best solution. Please see my answer.

  • In Ubuntu 18.10 the wayland session is installed, but it is not used by default.

  • @karel actually it is used, and many users with older GPU's can't get past the Ubuntu boot logo with the 5 rotating dots (or gdm3 not starting). Disabling wayland in this way solves that problem and allows the machine to fully boot properly.

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.


I had the same problem with a new install of 19.04 on a Windows Hyper-V VM.

I was able to press Alt-F2 to get to the secondary TTY terminal and login and edit this file. Rebooted, and now have access to the GUI-desktop.

  • I guess I have the same problem but when I stop holding Alt+F2 the first terminal come back Can so help me ?
