LightDM, or: an examination of a misunderstanding of the problem

Filed under
Software

LightDM's a from-scratch implementation of an X display manager, ie the piece of software that handles remote X connections, starts any local X servers, provides a login screen and kicks off the initial user session. It's split into a nominally desktop-agnostic core (built directly on xcb and glib) and greeters, the idea being that it's straightforward to implement an environment-specific greeter that integrates nicely with your desktop session. It's about 6500 lines of code in the core, 3500 lines of code in the gtk bindings to the core and about 1000 in the sample gtk greeter, for a total of about 11,000 lines of code for a full implementation. This compares to getting on for 60,000 in gdm. Ubuntu plan to switch to LightDM in their next release (11.10).

This is a ridiculous idea.

To a first approximation, when someone says "Lightweight" what they mean is "I don't understand the problems that the alternative solves".

Netrunner 14.1 – Main Edition (Frontier)

The “14.1” indicates an updated and polished release of Netrunner 14 LTS on the same underlying base. Since 14.1 is using the same base “trusty” like Netrunner 14, there is no need for users of 14 to migrate: Simply updating from the shared backports ppa of the Frontier release cycle should give the same result, while keeping customizations in place.
