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

Filed under

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".

Suse: Question. What do you call second-place in ARM enterprise server linux? Answer: Red Hat

ARM TechCon Suse is claiming victory over Red Hat by announcing – and these caveats are all crucial – "the first commercial enterprise Linux distribution optimized for ARM AArch64 architecture servers." In plainer English, Suse has developed an enterprise-grade Linux distribution that runs on 64-bit ARM servers (should you happen to ever find one). Suse claims this software is a world first because it is a finished commercial product, thus beating Red Hat to the punch: Red Hat Enterprise Linux Server for ARM is still only available as a beta-like development preview.
