Login Process Variant Flow Charts

Horizon_Brave · 2016-09-14 20:30:05

Hi all...so having a free copy of Visio and some time to burn, I made up three flow chart diagrams that take a high level over view of what the process is, and what files are sourced and what programs are ran during the distinct login attempts.

1. Login via Console
2. Start X via Startx (already logged in)
3. Login / Start X / using Display Manager

I think these three methods are he main methods of how 90% of us actually open our linux sessions?

If anyone here finds the information in the charts, incomplete, or want to add anything please please feel free, or post here and let me know what I should add. There's a definite limit to how much I can reasonably fit, but there's plenty of space left for now, so if you have any suggestions please post here.

All in all what do you guys think?

how is this information generated?

definitely manual... aka, hunting around various sources online. Debian Admin book, arch wiki, freeopendesktop etc... Like I said, any pointers on how to improve and flesh it out would be great! I'll obviously have to widen the images a bit, and clean it up, to make them all more uniform. Would digging into the whole PAM authentication be a good next step to add?

I can't comment on what are good things to expand this with, or what may introduce confusion, as I don't understand the process myself, however I would like to understand it, as understanding the process tree between lightdm saying "OK GO!" and the openbox autoruns getting called would help me with a troubleshooting task I have on hand ( I haven't asked for assistance yet, still doing my "due diligence").

My thoughts exactly. But please do make suggestions about what I could branch out on. With out combined ignorance of the process we can fill in the gaps So far I have a night of reading about PAM ahead of me
