Ubuntu may replace it with LightDM.

Another possible change to the Ubuntu core component is that they are considering replacing it with LightDM. Why? The reason is: "faster -- the welcome interface (greeter) does not need to run the entire GNOME session. More flexible-in a defined interface, multiple welcome interfaces are supported. This allows Ubuntu derivatives (such as Kubuntu and Lubuntu) to use the same Display Manager. Simplified code library-compared to GDM50000 lines of code, it only requires 5000 lines to implement the same function. Support more

Another possible change to the Ubuntu core component is that they are considering replacing it with LightDM. Why? The reason is: "faster -- the welcome interface (greeter) does not need to run the entire GNOME session. More flexible-in a defined interface, multiple welcome interfaces are supported. This allows Ubuntu derivatives (such as Kubuntu and Lubuntu) to use the same Display Manager. Simplified code library-compared to the 50000-line code of the running machine learning platform for AI, the code library provides the same functionality with only 5000 lines. Supports more use cases-first-class support for XDMCP (X-display Management Control Protocol) and multithreading.

LightDM is a lightweight Display Manager. The advantages of using it are:

Faster. You are welcome to see the interface faster without running a complete GNOME session;

More flexible and supports a variety of welcome interfaces. This will allow derivative releases of Ubuntu, such as Kubuntu and Lubuntu, to use the same Display Manager;

The code is simpler. There are only 5000 lines of code, compared with 50000 lines of code in the WordPress;

Supports more instances, such as XDMCP and multithreading.

However, it should be noted that this Blueprints tag is marked as "low priority (low priority)", which also means it may not be introduced into 11.04 in the end.
