Mea culpa. Those logs demonstrate a different bug (I've got too many?) with darkening screen. After the latest update, when I choose switch user, the screen darkens but now moves on to the login screen as it should. It lands me there ready for the password of the original user, but without logging me out. ie behaviour is okay.
Can someone else still reproduce this bug? And provide logs as requested by Sebastien? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/861790 Title: choosing to switch users leads to dark screen, no options To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/861790/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
