Missing date & time applet from top Unity panel


Answer #: 1

Having date and time gone on Ubuntu 13.10 beta, after next reboot, this command solves the problem:

killall unity-panel-service

Answer #: 2

Click the Ubuntu logo in the top-left. Search for and open “Time and Date”. Open the Clock tab.

Make sure the box “Show a clock in menu bar” is ticked.

Also make sure the package indicator-datetime is installed.

Answer #: 3

Double check that indicator-datetime is installed. Go to terminal and type

sudo apt-get install indicator-datetime

Now log out and then back in.

Answer #: 4

Reinstall indicator-datetime. It should be installed by default, but just in case you have removed it unknowingly, it is best to run the install command again.

sudo apt-get install indicator-datetime

Next, we are going to reconfigure the date time:

sudo dpkg-reconfigure --frontend noninteractive tzdata

Lastly, restart unity.

sudo killall...

In previous versions of Windows, the Internet Time tab was not built-into the Date and Time applet, but was added there by the Windows Time service. In Windows 7 I found weird things happening, such as seeing the service running although it was set to Manual, or of seeing Internet Time displayed and time-sync done even when the service is disabled.

I'm starting to think that Windows 7 will start the service when time-sync is to be done, no matter what is specified as its Startup type. I still don't know whether the Internet Time tab is now built-in or is still being added there by the service on its first run.

It seems however likely to me that there is still some connection between the service and the Internet Time tab, so that some corruption caused this mechanism to malfunction.

The Time service is defined in the registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W32Time. In case that the problem is caused by registry corruption, I have posted...

The following article will list some of the most important panel applets, also called indicators, for Ubuntu 11.04's Unity interface.

The Ubuntu 11.04 (Natty Narwhal) operating system introduced a different user interface, designed by Canonical, called Unity. The default indicators are nice, but many people complained that they miss their usual applets on the panel.

CPU monitors, system load indicators, bandwidth statistics, weather indicators, RSS news feeds, DropBox handlers, and many more other applets can be quite easily installed on Ubuntu 11.04.

This article will show a list of ten most used Unity indicators (panel applets), with installation instructions and screenshots. At the end of the article we will also list other indicators, less important, and where to find them.

1. Weather Indicator

This is the most easy to install indicator, as it is provided in the default Ubuntu repositories. Just open Synaptic or Ubuntu Software Center, search...

Panel indicators are very handy when it comes to access bold features of application or any standalone indicator which offers various functionality for the desktop to make user experience better. This time I tried to gather all available indicators for 14.04 LTS in one place, so you guys don't have to explore the internet for specific indicator and you can also tell me if I missed any indicator here(Just drop me a line via contact page, I will try to include in the post, if possible).

If you are using Ubuntu 12.04 then you have to checkout this indicators collection


for Ubuntu 12.04 Precise. You can install these indicators in other desktop like Gnome-Classic, Mate, Cinnamon, Xfce and others but I can't say that every indicator will show up in every desktop, so I tested these indicators under Unity desktop. I didn't check these indicators on Linux Mint, hopefully they shall work with Linux Mint 17 without any problem.

Installed kdm and used it as default. After i login into unity through i do not see my username.But if i go back to using lightdm, i have no problems.

Anyone knows how to use kdm as default and still not lose username in unity..?


To re-enable the username on Unity panel, in terminal:

gsettings set com.canonical.indicator.session show-real-name-on-panel true

To disable, simply change true to false:

gsettings set com.canonical.indicator.session show-real-name-on-panel false

Note: You must reboot for these changes to take effect.

This happened to me once-- Try this command in Terminal:

sudo apt-get install indicator-session

What may have happened is that the package was deleted. Like I said, it happened once to me, so thiS MAY (I can't stress that word enough) work for you....

The Gnome Flashback desktop environment is a simple and great way to get back the old style classical desktop if you do not like Unity desktop, like many.

Gnome Flashback is based on GTK 3 and provides a desktop interface visually similar to the old gnome desktop.

Another alternative to gnome flashback is the MATE desktop from linux mint and XFCE desktop, but both of them are based on gtk 2.

Install Gnome Flashback

Install the following package on your Ubuntu system and you are done.

$ sudo apt-get install gnome-session-flashback

Now logout and at the login screen press the settings button on the box that asks for password. There would be 2 options, Gnome Flashback (Metacity) and Gnome Flashback (Compiz).

Metacity is lighter and faster, whereas Compiz gets you the more fancy desktop effects. Here is a screenshot of my gnome flashback desktop.

It uses a wallpaper from elementary OS and also Plank dock with no bottom panel. This...

One of the irritating bugs in Ubuntu 14.04 is the missing date time from the top panel. Normally, there is a date time indicator displayed on the top right corner of screen but for some users this is disabled by default.

What is more frustrating is that if you try to enable it or configure it by going to System Settings->Time & Date->Clock section, you’ll find that the option has been grayed out. You simply cannot change it.

In this quick post we shall see how to ix the issue of time and date settings greyed out in Ubuntu 14.04.

Fix date time missing in the menu bar in Ubuntu 14.04:

To fix this issue, there are few solutions. We shall see them one by one.

Solution 1:

Open a terminal and use the command given below. This is optional and just to make sure that you have the indicator installed already.

sudo apt-get install indicator-datetime

Once we have made sure that the indicator is installed, next step is to reconfigure...

People always say network manager icon,sound icon,or other applets is losing from the gnome-panel and want how to get the icon back.Despite these icons’ missing may be caused by series reasons,the first solution come to my mind is add them back by “Add to Panel” in right-click on panel menu.

All these icons can be re-added onto the gnome-panel,so we just need to know what’s the applet name.See following picture:

The picture shows all applet names,you can check them by right-click on an icon and select “About”.
So if sound icon,mail notify icon,or graphics driver icon is missing, add indicator applet to panel.If switch user,shutdown,etc.., add indicator applet session.If network manager,add notification area.If date and time,add...

So a couple of weeks ago my network manager icon stopped appearing; I still get automatically connected to my saved networks and the internet works fine, etc. If I go into System Settings and look at the Network settings I can still see all the networks, only the icon that's normal in the top bar is missing.

I have no idea what caused this, I don't remember installing anything. I think it just happened after a regular update.

I tried these commands to make sure I was properly up-to-date (which I found on another forum post)

sudo apt-get -f install sudo apt-get update sudo apt-get upgrade

That didn't do it so I found this post: Network manager indicator missing I followed the instructions in those answers;

sudo apt-get purge network-manager-gnome && sudo apt-get install network-manager-gnome

And, quoted from an answer there:

Add nm-applet to the Startup Applications (which may be found by entering "Startup Applications" in the Dash).

We have build a city builder game from the ground up before in pure Javascript. This was a very time consuming effort, and since we [were] looking now for something similar using Unity this city builder kit was the answer. We have tried it out and where impressed by the quality and ease to use! These guys really did an outstanding job!

Martijn Gun Van Der

Awesome Building Strategy Kit!
What can I say? .. wow, just wow! :) you guys making things above expectations. I haven't fully tested yet Unity Project and all new features, but what I've seen from Video and new description simply awesome.

Update: Let me start by saying that I'm a big fan of 'Clash of clans' game, and if you are looking for an asset that will help you to develop something similar, then the City Building Kit is exactly what you need. Seriously, if you think of complexity of the games like Clash, how much must be done before you own creation turns into a game, then this Kit...

Ubuntu 14.04 Trusty Tahr has just been released, and I’m sure you are about to install it. I’ve put together a few ideas for what to do after installation in order to make it work better for you. You’ll find that below. First, a bit of ranty background.


Originally, Ubuntu was a great thing. Years ago I used a Unix like system for various things and got comfortable with what we now call the “command line.” Then I used DOS, and that was still a command line operating system (but with different commands) and that...
