[Running Ubuntu Desktop 14.04.2 x86_64 -- 3.16.0-41-generic -- on an Intel DuoCore T9300]
My Unity bar indicator-datetime
disappeared suddenly about a week ago. No warning and no other problem apart from 2 days later the disappearance of indicator-stickynotes
too.
Those two events only affect my account-session on my workstation. Other users on the same machine, using the same hardaware, are fine on both counts (indicator-stickynotes and indicator-datetime).
I am in the process of filing a specific bug for `indicator-stickynotes, although the coincidence is too much of a red-flag not to raise broader questions about the unity environment itself or perhaps before that, just about my user profile... In reality I am in the dark.
Interestingly indicator-datetime
still shows in the Unity bar on the session login screen. After login it is gone. All system-settings are functional including the "Time & Date" one. Nothing is greyed or absent there as I read was the case elsewhere.
Since then I have read what appears to be duplicates on askubuntu.com as well as here. I did tried to apply proposed fixes, including fixes identifed as accepted solutions. I think I was thorough. Nothing worked.
Here is a quick replay of what I tried:
$ alias sag='sudo apt-get'
Then:
$ sag install indicator-datetime

There is nothing of note in the remove-log file as far as I could see.
Then:
$ sudo killall unity-panel-service
again exited quietly with no change at all in the unity bar.
Curiously as I tried to reinstall unity-control-center
, I found it was already there, although I had just (apparently) removed it.
$ sag install unity-control-center

Help !! In need of suggestions assistance to solve this indicator-datetime + indicator-stickynotes disappearance.
EDIT 1:
$ /usr/lib/x86_64-linux-gnu/indicator-datetime/indicator-datetime-service
Indicator-Datetime-Message: indicator-datetime exiting; failed/lost bus ownership
sudo apt-get install ubuntu-desktop
. I did not carry that out because the proposed a number of up to date packages that are already installed on my system. Not understanding why apt-get would find it necessary to reinstall them + games + .... I just abstained until receiving some advice. – Cbhihe Jun 26 '15 at 18:22
