[gdm-list] autologin performance ...

[Michael Meeks <michael meeks novell com>]

Hi Jon,

	This is prolly the world's most ignorant question ;-) but - I'm trying
to accelerate bootup and auto-login by avoiding creating a gnome-session
as the gdm user, and starting up so much stuff [ it's quite a lot on the
bootchart ]. Is that something we can do already ?

	I fiddled around trying to abuse gdm-welcome-session.c to just log me
in as me ;-) and other vile hacks in gdm-simple-slave.c (of very mixed
success - mostly hurt by the fairly complex init sequence getting
pre-empted).

	Anyhow - so, before I sink yet more time bumbling around in here - I
wondered: do you have a sketch design for faster auto-login lurking at
the back of your mind, and/or any recommendations ? I'm happy to attempt
the typing / testing of course if only to learn some gdm internals.

	Also; although, the code structure is seeping slowly into my mind; what
would have really helped would be some simple / ASCII interaction
diagrams: who forks whom, and how they talk to each other. I attach a
somewhat edited, and cut-down set of the debug info that is traced at
startup, of a normal login session - would you be interested in me
cleaning up & further annotating that to add to INTERNALS ?

	Thanks,

		Michael.

The interactions during a typical gdm login sequence look like this:
