How to change login screen

Solution 1

You can install another display manager such as LightDM, MDM, Slim, GDM

sudo apt-get install lightdm

select LightDM

sudo dpkg-reconfigure lightdm

You can add greeters to have nice themes How to change the LightDM theme/greeter?

There is also lightdm-kde-greeter mentioned here How do I install KDE and retain LightDM as a login manager?

Solution 2

for 13.10 or older

use the following command to set lightdm back to normal

sudo /usr/lib/lightdm/lightdm-set-defaults --greeter unity-greeter

reboot for the changes to take effect

This works for going from xubuntu and back to unity-greeter, ubuntustudio and back, and kubuntu back to unity-greeter as well.

14.04

There is no longer a /etc/lightdm/lightdm.conf file and the set-defaults command is no longer available.

Taking a look at my old 13.10 files, I discovered what changes need to be made to select unity-greeter.

There needs to be a file named 50-unity-greeter.conf located in the directory /etc/lightdm/lightdm.conf.d run the following commands to create and/or update this file to use the unity-greeter:

echo '[SeatDefaults]' | sudo tee /etc/lightdm/lightdm.conf.d/50-unity-greeter.conf
echo 'greeter-session=unity-greeter' | sudo tee -a /etc/lightdm/lightdm.conf.d/50-unity-greeter.conf

Don't forget to save any unsaved files before you restart lightdm because you will be logged out!!!

sudo service lightdm restart

  you could try sudo apt-get purge lightdm-kde-greeter but that very well may just uninstall kde (plasma desktop plasma this plasma that etc...) along with it so proceed with caution and only accept the changes after reviewing the changes to be made.

  I was facing the same problem, I was importing a con.php file in another file. It was throwing an error when I use con as the file name which I was importing when I renamed it to connection.php and import it again the error was gone. <br> I think con will be a keyword or something else that's why it was showing error.

If there were no quotes about the file name, there would be a syntax error printed
