Comment 8 for bug 941673

Hi Guys,

As a workaround for the time being one could do the following (tested on 12.04):

Remove accountsservice
sudo apt-get remove accountsservice

Edit /etc/lightdm/lightdm.conf and add the following line :
greeter-hide-users=true

Then restart lightdm or reboot the machine:
sudo service lightdm restart
