Turn Off Shutdown Confirmation Dialog Box In Ubuntu


1. Even though we are showing this in Ubuntu 14.04, this tip should work in other recent versions too.

2. Turning off the shutdown and restart confirmation dialog box will also turn off the confirmation dialog box for logging out and locking your Ubuntu machine.

Turn Off Shutdown and Restart Confirmation Dialog Box

Before doing anything, if you observe the options under the power button, you will find that there is no Restart option by default. This is because the Restart option is found in the confirmation dialog box. After you disable the confirmation dialog box, the restart option will appear in the list of options.

In order to turn off the Shutdown and Restart confirmation dialog box in Ubuntu, we need to change an indicator-session setting. To do that, open your Ubuntu terminal and type:

Once you press the Enter button, the confirmation dialog box will be disabled immediately. There is no need for you to restart or log off. Once you are done executing the command, you can safely close the terminal.

As said before, if you press the power button in the top panel, you will see that the Ubuntu has automatically added a Restart option so you can quickly restart whenever you want.

In the future, if you ever want to re-enable the Shutdown and Restart confirmation dialog box, just replace the value “true” with “false” in the above command. Once replaced, the command will look like this:

Once you have executed the above command, Ubuntu immediately enables the shutdown and restart confirmation dialog box. There is no restart or log off required to see the changes.

Automatically Lock & Unlock Your Computer With Gatekeeper

How many times have you walked away from your computer at home or work and forgot to lock it? If you’re around people you trust, this may not be an issue for you. However, if you have nosy co-workers, family members or house-mates, then you’ll definitely want to think twice.

GateKeeper is a tool that helps to keep your computer safe. It does this by automatically locking your computer when you walk away and unlocking it when you return.

By using GateKeeper, you won’t have to worry about or wonder if you locked your computer because once you’re a certain distance away from the USB Lock; the Key will disconnect and automatically lock it for you.

Before Getting Started

In the GateKeeper box you’ll find a Key, USB Lock, two CR2032 batteries (one is a spare), a key ring and a quick start guide.

Before setting up GateKeeper on your computer, you’ll need to power up the Key. You do this by opening the back cover and inserting one of the included batteries.

When opening the Key cover, I noticed that it was a bit difficult to take off. Plus, it seems like it can easily be snapped or broken if too much force is used; so you’ll need to be extra careful.

Once the cover is back on, it’s safe to insert the USB Lock into a USB slot on your computer. It’s best to use one that is closest to you so that the Lock can easily connect to and communicate with the Key.

Setting Up the GateKeeper Key

Next you’ll need to download and install the GateKeeper software. It’s available for Windows 7, 8 and 8.1, as well as Mac OS X (version not specified). For the purpose of this review, Windows 8.1 was used.

While the GateKeeper setup is running, you’ll also see a Device Driver Installation Wizard window. This is so that you can install the software driver for the USB lock. You may also see a Windows Security window appear, asking if you’d like to install the device software from “Texas Instruments, Inc” (GateKeeper’s Publisher); be sure to “install” it.

Once everything is installed, you can open the GateKeeper application.

Finally, you can go back and set your preferred Lock Distance. When you’re done, be sure to save and close the window. As long as the GateKeeper window is open, your computer will not lock and you won’t be able to test it.

Getting the perfect distance to suit your preference will take some trial and error. It’s best to have someone else help; they can sit at your computer and watch for the screen to lock and unlock while you walk back and forth to see how long each distance takes.

While testing, I found that the Key needed to be out in the open to best communicate with the Lock. Keeping it in my pocket or balled up in my hand, caused unwanted actions (randomly locking, not locking or unlocking at all). To combat this, I sat the Key closer to the USB lock while the computer was in use, which stopped it from randomly locking and unlocking the screen.

GateKeeper On Your Mobile Device

GateKeeper also has an Android and iOS app that works in conjunction with the Key. It enables users to locate and track objects. Unfortunately, I could not get the Android app to work; it would not detect my Key in order for me to add it. Being able to keep up with your valuables is definitely an added bonus – if you can get it working.

Final Thoughts

Needless to say, GateKeeper provides some beneficial features. It’s easy to set up and even easier to use. Although I did find it a bit buggy at times, it does provide a convenient extra layer of security to your computer and is a joy to use.

Reinstall Cortana: “Hey Cortana” Not Working – How To Fix?

Cortana is the voice assistant provided with Microsoft Windows 10 and up until build number 1809 it was integrated within the Search as well. That means you could search for any kind of file or internet query without leaving your desktop.

Cortana can be used to perform a lot of functions with a simple voice command if configured correctly. After updating Windows, some users are reporting that Cortana isn’t working as usual and shows up errors like “Critical Error Cortana isn’t working. We’ll try to fix it the next time you sign in.”

The most usual reason is a problem with Microsoft Credentials. Faulty credentials can interfere with Cortana running properly, thereby causing the error.

There are some fixes you can apply that will help you resolve the error Hey Cortana not working.

After you install an app or update your Windows to the latest version, the permissions required to access Cortana may be changed. To review these changes, do the following:

In the Cortana settings, make sure the checkboxes next to Let Cortana respond to “Hey Cortana” and Use Cortana on Lock Screen is checked.

Your username and password play a major role in integrating the software experience in Windows 10. Faulty credentials can lead to the Cortana app not working as it is supposed to work.

Sign out of your Microsoft account and log in again to your system to reset the Microsoft credentials to its new values.

Some minor runtime errors can conflict with Cortana effectively prevent it from performing normally.

A simple restart of the Cortana process should be enough to fix a small runtime error.

Open Task manager from the WinX Menu.

Since Cortana is deeply built into the Microsoft Windows 10, it is impossible to simply uninstall Cortana. You can, however, re-register the Cortana into your Microsoft Inventories to reset it.

To re-register Cortana you need to input a command into PowerShell that will reinstall and re-register Cortana for the available users.

To reinstall Cortana for the Current User:

Type the following command into the PowerShell input field and press Enter:

To reinstall Cortana for all Users:

Type the following command into the PowerShell input field and press Enter:

After you press Enter, you will see a Deployment Operation Progress message. Once the process finishes, you should be good to go.

With every new update, Microsoft adds new features and languages to be compatible with Cortana. In case you might have missed an update, install the latest versions of Windows provided through the ‘Update’ portal.

Every new update brings certain changes to the Registry keys and values that may change the way certain apps work.

Open Registry Editor. Type regedit in Command Prompt and press Enter.

Navigate to the following path and check the registry values to eliminate the possibility of a registry error:


In older versions:

Locate the entries titled BingSearchEnabled and CortanaEnabled.

Set their Value data to 1.

How To Enable Hibernate In Ubuntu 12.04

Why Hibernate is disabled by default in Ubuntu 12.04?

Some of you who are used to the Hibernate feature in Ubuntu might be asking “why is this missing in Ubuntu 12.04?”

The reason behind this is because Ubuntu’s Hibernate feature has always not been working well in many computers. For new hardware models, the Hibernate feature often don’t work by default. In some instances, the Hibernate feature will even lead to data loss. The rationale behind the removal of the Hibernate button is:

For Ubuntu to present a Suspend function that doesn’t work is unprofessional, and presenting a Hibernate function that doesn’t work (and destroys data by never waking up) is even worse.

After much discussion and debating, the final decision is to disable Hibernate by default on all computers, unless the computer is on a whitelist. The whitelist will include all “Ubuntu Certified” computers that have been tested and proven to work with the Hibernate feature. So if you are not seeing the Hibernate button, most probably your PC is not “Ubuntu Certified”.

Where to access the Hibernate feature?

How to get back the Hibernate feature?

If you are not sure if your PC supports the Hibernate feature, open a terminal and type pm-hibernate. If your PC succeed in going to Hibernate mode and you have no problem waking it up, your PC supports the Hibernate feature. You can then proceed to the next step to restore the Hibernate option.

In the terminal and open the following file:















Add the following:


Re-enable hibernate by default










Save (Ctrl + o) and exit (Ctrl + x).

Restart the PC. The Hibernate option should return now.
