I want sometimes to be able to login as root into the Unity desktop manager. I made a fresh install of ubuntu-16.04.6-desktop-amd64 and in order to be able to login as root added the line: greeter-show-manual-login=true to /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf This leads to that I can't login to the desktop at all and I am only given the message "The system is running in low-graphics mode". The system is however running in the background, I can login to the terminal with Alt-F1. In my older installation of the original ubuntu-16.04 this has worked without a glitch. My system is a laptop, Yoga Pro 2. What is wrong and what can I do about it? Thanks in advance H
Sorry,I was wrong It was not /etc/lightdm/lightdm.conf but /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf that shall contain the line greeter-show-manual-login=true. Now it works, problem resolved. H
