More: creating a new 'test' account on the i5 machine and changing auto login to that account results in auto login working OK for 'test'.
That seems to suggest that a fault has somehow arisen in my usual account's control files. I'm hoping someone will discover such a fault and how to correct it by a tiny action. I am reluctant to go through the process of trying to ensure I have saved all my normal account's files and settings, then deleting and recreating that account! I try only to do that when I totally reload a machine and then only with a new LTS, which will not be until 16.04. I'd be pleased to receive via this forum requests for diagnostic information. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1250875 Title: Lightdm sometimes fails to auto login Status in lightdm package in Ubuntu: Confirmed Bug description: Using ubuntu 14.04 and sometimes when I boot into ubuntu lightdm fails to auto login, and I must login manually in the unity greeter.
