I have just noticed this: I created a second account (administrative) and gave it a distinct desktop background. Both accounts were set autologin=NO.
On rebooting from a complete power off (at the wall), I of course got the login screen, BUT if I dropped down to the second account, its distinctive desktop background was displayed, whereas on returning up to my usual sole account, the background went to the standard purple, instead of my account's distinctive desktop background. I guess there is some sort of corruption in my account's files. I expect that complete removal of my account, followed by its exact re- creation might remove this problem. I am tempted to try, after the appropriate backups of course. By the way, am I talking to myself here, or is anybody who might be able to solve this also listening? -- 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.
