Bug Description

lightdm changed it's syntax with the most recent version and also no longer requires a configuration file causing the automatic login normally configured for the 'ubuntu' user to stop working.

Derivatives will still use /etc/lightdm/lightdm.conf but you can't rely on the contents anymore and just replace a string with a regular expression. Standard ubuntu doesn't have /etc/lightdm/lightdm.conf.

This failure is with the mythbuntu lightdm conf but will happen on all cases of lightdm right now.

Seems to me that this was fixed:

casper (1.273) oneiric; urgency=low

  [ Mario Limonciello ]
  * scripts/casper: Add support for SAS controllers now that 575297 is fixed.

  * lightdm no longer ships with /etc/lightdm/lightdm.conf in its package.
    Updating 15autologin casper hook to create one when missing. (LP: #819609)

Reviewing the diff, no it wasn't. It only fixed the ubuntu scenario. The derivative scenario still doesn't work properly (it doesn't check for and set the proper lines)

Just verified while performing ISO Testing with Ubuntu Desktop i386 and also Ubuntu is still affected from this bug.

Confirmed, got this bug while installing Ubuntu 11.10 Alpha 3

Hmm, my latest casper upload should take care of most of the derivatives as well by removing any existing lightdm.conf prior to generating a new one.

The only case that's failing is when lightdm can't find the "default" session (it's hardcoded to "ubuntu" apparently).
This is a separate Launchpad bug, bug 806408.

Using the Xubuntu oneiric-desktop-amd64.iso image dated 2011-08-14, auto-login to the live session worked. I have not attempted auto-login in any other session today.

Solved in Ubuntu Desktop i386 (20110830)

Mario, do you know if this still needs to be open, considering comment 6 and comment 7?
