My clock has disappeared [closed]
Solution 1:
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
com.canonical.indicator.datetime
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.
Solution 2:
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
Solution 3:
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.
