I'm using lockscreen that came with Ubuntu Gnome. It's called GDM. can I replace it with LightDM or lockscreen that comes with KDE , LXDE or others?

what are the names of these packages? how to install them?

If that's too broad then

  • How can I just install LightDM without affecting my Ubuntu Gnome Installation?
  • How can I uninstall it and get GDM back if I don't like the experience?

To install an alternate login manager use software manager or the command line

sudo apt-get install kdm

You can try slim or lightdm, both probably lighter then kdm, or try them all.

To remove them

sudo apt-get purge kdm

or slim or lightdm

To select which one to use use sudo dpkg-reconfigure gdm or edit /etc/sysconfig/displaymanager

sudo dpkg-reconfigure gdm

you will get a screen where you can select which display manager (login screen) to use.

enter image description here

Use you up/down arrow keys to select and hit enter key.

or 

sudo nano /etc/sysconfig/displaymanager

and change to the dm you wish, such as 

DISPLAYMANAGER=”kdm”

sudo dpkg-reconfigure gdm has the advantage of less typing and less typographical errors.

Locking the screen when you are inactive is a different issue and is a property of the screensaver you use. By default it is gnome-screensaver but xscreensaver is probably the most popular alternate.

To configure and change screensaevers see Configure screensaver in Ubuntu
