I'm trying to enable graphical root login with commands on Ubuntu 14.04.2:

sudo passwd root
sudo sh -c 'echo "greeter-show-manual-login=true" >> /etc/lightdm/lightdm.conf'

Portions of the VMware tools crash associated with lightdm

Is there any way to enable root access graphically at the login menu without conflicting with the VMware tools?

Execute this command

sudo gedit /usr/share/lightdm/lightdm.conf.d/50-unity-greeter.conf

Then add this statement


Restart your machine and It should work.

  • I get the following error now though, I guess its related: Error when found when loading /root/.profile: stdin: is not a tty Mar 26, 2015 at 18:13
  • Can you copy paste contents of /root/.profile file in question, execute this command: "sudo gedit /root/.profile" then copy contents of file and paste it into your question. Mar 27, 2015 at 11:42
  • And also try adding "pty=True" (without quotes) at the end of /root/.profile Mar 27, 2015 at 11:42
  • adding "pty=True" yields the following in terminal: (gedit:7308): Gtk-WARNING **: Calling Inhibit failed: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files Mar 27, 2015 at 16:52
  • hopefully you understand the edit in the question (formatting is different obviously) Mar 27, 2015 at 16:52
