Bug Description

This morning I experienced an interaction which left me a bit concerned.

I took a sleeping laptop to the office, opened it, and the usual login dialog came up. I then plugged in an external monitor, and it unlocked.

Anybody experienced something similar recently?

Looking through the logs there's nothing relevant that could be attributed to a crash or similar.

Here is auth.log:

Here is syslog:

Nothing suspect there either, it seems.

Any hints about what else I should look at?

could you add your ~/.cache/upstart/unity7.log as well?

There's no time in most lines in that file unfortunately, but this might be it:

These last lines seem unrelated, but they repeat hundreds of times in that file.

Would be nice to know which version of unity are you running.

Also this line
"Jun 29 10:00:18 nomade compiz: gkr-pam: unlocked login keyring"
suggests that the "unlock" comes from pam itself.
