I did some independent research into this after smashing into this bug on elementary OS loki: the issues are documented on on the light-locker project page at https://github.com/the-cavalry/light-locker but the source hasn't been touched since 2015, and the project seems to be in development hell with no developers or projects assuming ownership. the readme states:
> To use light-locker with systemd, you need at least lightdm 1.7.0. > light-locker doesn't work with lightdm version 1.7.5-1.7.9 loki uses lightdm 1.18.3 so it's at least .11 more broken now. If somebody knows how to ping Sean Davis or the lightdm developer Robert Ancell it couldn't hurt. in the meantime elementary users can workaround the issue by disabling locking in security panel. Which will allow you to return to your session, but may allow your mates to mess with you. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1320989 Title: black screen after longer screen lock To manage notifications about this bug go to: https://bugs.launchpad.net/elementaryos/+bug/1320989/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
