For root login to work on Ubuntu 12.04 / 12.10
echo "greeter-show-manual-login=true" >> /etc/lightdm/lightdm.conf
This works with Ubuntu 11.10
Few minutes back I completed Ubuntu 9.10 installation. Now I am using latest Ubuntu for my routine work.
As I have already expressed my love with root access in previous post, this time I was looking for a way to use root login for GUI. One of my colleague who loves Ubuntu found simple way to login root over GUI.
Following are the two steps required.
sudo passwd root
once password for root is reset. You can login root on GUI using Other.. option available on Login Screen
With the earlier version of Fedora & Ubuntu root access was blocked by default. for GUI but this time all you need to do is to reset password for root.
Although this is not recommended for normal user, but many linux admin will love this, as it saves time to find alternate way to get root login.
