Just installed Ubuntu 16.04. It uses lightdm and unity-greeter.

If only one user is logged in (Unity session), the login screen does not look fine after logout, these indicators are missing: power, sound, keyboard …

Is it a bug ?

The only thing there is in the top right corner is 'onscreen keyboard' menu.

In a console (ctrl-alt-F1), restarting lightdm brings the indicators back.

After a machine reboot on the other hand, the login screen has everything.

  • I see this too, also the wallpaper doesn't show up like it should for me (like in this question). For me, if I lock the screen and get the unity-greeter then it works fine, but if I log out or switch user then I get LightDM which is broken as you describe. – seanlano Jul 31 '16 at 02:37

    I have filed a bug report for this: https://bugs.launchpad.net/ubuntu/+source/unity-greeter/+bug/1608164 – seanlano Jul 31 '16 at 03:03
  • Also: I get a black screen when I try to get a tty via Ctrl-alt-F1..F6 -- I think it still works though when I type a login and password in the dark. – epsicot Jul 31 '16 at 13:52
  • I believe that the login screen is on tty7, i.e. Ctrl+Alt+F7. – seanlano Jul 31 '16 at 23:14
  • Yes the login screen is on tty7. But yesterday my tty1 to tty6 were black screens. I don't know if it is related to the login screen bug or if it is a completely different one. Today after a system restart, they are normal however. – epsicot Aug 01 '16 at 09:36

    I received the lightdm update (1.18.2-0ubuntu2) which seems to solve the missing indicators problem on the login screen. But the blank ttys come back. Looks like there may be another bug. – epsicot Aug 11 '16 at 21:12

The bug has been confirmed, in this Launchpad tracker. There is a fix committed to the lightdm package, version 1.18.2-0ubuntu2.

It's currently in the proposed repo for Xenial (16.04) - I've enabled the proposed repo from the instructions here and installed the updated version. (I also followed the selective upgrades instructions, so that only packages I choose update to the proposed versions.)

If you don't want to play around with the proposed repository, that's OK - the updated package should make its way into the normal updates soon enough.
