So I have looked online (believe it or not) and I can't seem to find anything to help me with my issue. My clock just disappeared. Here's a screenshot!

    I had the same experience after upgrading from 13.04 to 13.10. It's one of the reasons why I'm not longer on 13.10.

  • This is NOT a duplicate of the said question. This is not happening in Gnome, but in Unity. FWIW, restarting unity brought it back in my case. Jan 21, 2014 at 11:47

    I think that it is not a off-topic, since to me it as just a mistake, removing some packages....

  • Why is this off-topic? The one specified reason is question for development version of Ubuntu which is not the case here. Is the real reason that 13.10 is no longer supported? Should that be a reason for question to be off-topic?

Similar thing happened to me after upgrade to 13.10. I found that this bug describes it: https://bugs.launchpad.net/ubuntu/+source/indicator-datetime/+bug/1237361

I have it solved now, not sure if by installing system updates, by changing all related attributes in dconf-editor for node


or just by restarting unity (Alt+F2 -> "unity --replace") as commenter in above mentioned bug said it may help.

So maybe try to play a bit with settings and then trying restarting unity would not be a bad idea either.

    (Dunno how this got marked as a duplicate — Unity ≠ Gnome.) Replacing unity can cause the window manager to fail, so you get windows without controls that you can't move or close. I've had the most success with sudo killall unity-panel-service, which reinstates the clock immediately.

    for me, unity --replace was enough. thanks for that!

    @scruss, you don't need the sudo. You can just run killall unity-panel-service as described in the bug, No clock in menu bar and can't edit Clock settings.

It's possible that it got uninstalled (most probably when you were trying to uninstall some other indicators). Try

sudo apt-get install indicator-datetime

And restart unity with

unity --replace

Then recheck your Clock settings. That should hopefully be the problem

    After running above comment I needed to also restart unity with unity --replace and my clock was back

For me check the clock settings solved the problem.. actually "Show a clock in the menu bar" was already checked, I had to uncecheck it, close the settings, reopen the settings, checked this option back and finally it worked.

  • It would have been good if you said where the clock settings were

    @Anake: "System settings" -> "Time & Date" -> "Clock".

    @AquariusPower A hearty killall unity-panel-service solves your problem. May 26, 2016 at 19:34
  • Thanks @JonasGröger the killall was the solution Aug 15, 2016 at 9:00
