@robert - I've seen reports from xubuntu testers where it was sometimes working. So I tried more on a completely brand new installation.
Lock - unlock fails - this continued for 3 attempts at which point I reached desktop. Lock and unlock cycle next time took 2 attempts. Lock and unlock cycle next time took 1 attempt. I was then able to lock and unlock at will. Attached all /var/log/lightdm logs from that session. ** Attachment added: "lightdm.log" https://bugs.launchpad.net/ubuntu/+source/light-locker/+bug/1656399/+attachment/4823518/+files/lightdm.log -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1656399 Title: Unable to unlock session after suspend using lightdm-gtk-greeter.
