LightDM is a <em>Display Manager</em>.
|
|
It is a long running process (daemon) that ensures that your graphical display is set up correctly.
|
|
</p>
|
|
<p>
|
|
The LightDM daemon spawns and manages two types of processes:

|
Display Servers - a process that combines graphical output from one or more process together to display on graphics hardware.
|
|
Also provides input from mice / keyboards etc to the process. For example X is a display server.

Sessions - a session is a process that has access to the display server and allows the user to perform tasks.
|
|
Often a session will be made up of a core component, the shell, that allows the user to run applications.
|
|
Both the shell and the applications communicate with the display server.
