Today in the evening I booted up my laptop and my login screen has changed to the following (taken from my N9)

my laptop

The login screen has changed to some old looking thing?

I can still login to my laptop and dpkg -l | grep greeter says

ii  lightdm-gtk-greeter                                         1.8.5-1ubuntu2~ubuntu14.04.1                                    amd64        simple display manager (GTK+ greeter)
ii  pantheon-greeter                                            2.0.2-0~r370+pkg43~ubuntu0.3.1                                  amd64        Pantheon Login Screen

The package lightdm-gtk-greeter some how got installed. Purging it and reinstalling pantheon-greeter fixed it.

To do it run the following commands in a terminal

sudo apt-get purge lightdm-gtk-greeter
sudo apt-get install pantheon-greeter --reinstall

  • I also having this issue ... but when doing the purge for the gtk greeter got this restult ... Package 'lightdm-gtk-greeter' is not installed, so not removed – George Barbaz Sep 2 '19 at 12:29
  • trying the pantheon-greeter reinstall to see if that fixes the issue – George Barbaz Sep 2 '19 at 12:32
