Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

I am setting up a production system (will be deployed to multiple devices), based on Lubuntu. The system starts X, logs in a user automatically, and runs a full screen GUI application. That's all it really does. I'm using openbox as the window manager - in production I don't really need a window manager but its useful during testing and development.

For a number of reasons that I don't want to get into here, I would like to avoid lightdm (currently in use), lvdm, or any other display managers that perform functions I'm not using.

So, I'm looking for a display manager that essentially just needs to create a local session for a predetermined user. A greeter is not necessary, remote sessions are not necessary, the ability to operate on a read-only file system (particularly, /var/lib is read-only, although /var/tmp is not) would be a major plus.

Is there a super lightweight display manager out there that just does the bare minimum necessary to create a local session for a user? Alternatively, is it possible to remove the display manager entirely and just explicitly start a local session with a window manager?

This question is off topic here, (software requests are, in general) and will soon be closed. You might want to delete it and as instead on Unix & Linux. Please don't crosspost though, if you want to ask there, delete this one first. –  terdon Oct 16 '13 at 22:11
Sorry, I didn't realize superuser was platform-dependent. I got an answer though, close away. :) –  Jason C Oct 16 '13 at 22:12
It is not! Not at all! It is just that asking for software is specifically off topic here but not on Unix & Linux. Questions about *nix are very welcome here, I spend almost all my time here answering Linux questions. –  terdon Oct 16 '13 at 22:14
