Suggested March 2024 How To Configure Screen Brightness In Ubuntu

If you are staring at the screen everyday, I am sure you will want to make the screen comfortable for your eyes. Adjusting the correct brightness is not only essential to protecting your eyes, it also helps to conserve battery power and reduce your electricity bill. In Ubuntu, adjusting the screen brightness is easy, but customizing it requires you to go deep into the settings. Let’s see how you can configure the screen brightness in Ubuntu.

Note: The brightness setting is only applicable if you are using a laptop. On a desktop, you can easily adjust the screen brightness on the monitor.

Adjusting Screen Brightness from the Settings

The easiest, and the most obvious way to adjust the screen brightness is via the System Settings. In the System Settings, you should see an option with the name “Brightness and Lock”.

Going into the Brightness section, you will be able to drag the slider to adjust the brightness level (assuming you are using a laptop)

You will also see an option for the system to “dim screen to save power”. Selecting this option will turn the brightness down when the system is idle (no keyboard or mouse movement).

More Not-so-obvious brightness Settings

If you feel that the brightness level in the idle mode is still too high, or that the system go into dim mode too fast/slow, here is how you can change the brightness settings.

Open a terminal and type:


Note: If it says the command is not available, you will have to install the dconf-tools package.

From here, you can change the “idle-brightness”, “idle-dim-ac”, “idle-dim-battery” and “idle-dim-time” settings. A quick explanation of the terms:

idle-brightness – the brightness level when the system is idle. I have set it to only 10% of the full brightness. You can set it higher or lower depending on your needs.

idle-dim-ac – Enabling this option will dim the screen when the system is idle and running on AC power.

idle-dim-battery – Enabling this option will dim the screen when the system is idle and running on battery.

idle-dim-time – the amount of time before the system transits into idle mode. The default is 90 seconds, but I have turned it down to 15 seconds.

The settings will take effect immediately upon changes. Once you have made the necessary changes, you can just close the dconf-editor.

Adjusting Brightness from the desktop

If your laptop doesn’t come with a dedicated brightness control button, and you don’t like to go to the System Settings to adjust the brightness everytime, you can install the “indicator-brightness” to directly adjust the screen brightness from your desktop.

In your terminal,


add-apt-repository ppa:indicator-brightness




apt-get update

Making the brightness level stick on reboot

If you have noticed, no matter which level you have adjusted the screen brightness to, on the next reboot, the brightness level will go back up to 100%. This is probably a bug that Canonical has not get around to solve. Here is a walk around to get the brightness level to stick.

Install xbacklight:


apt-get install


Open the “Startup Applications” and add a new startup item with the command:

The “40” in the above command is the level of the screen brightness, in percentage, that you want to set. You can change it to the value you want, say 60, or 80.

Note: xbacklight will only take effect after you have logged in. The brightness level at the login screen will still remain at 100%.

Adjusting the screen brightness may seem like an easy task, but apparently, there are more to it than the standard dimmer/brighter brightness control button. Hopefully, with this tutorial, you will be able to solve the brightness issue that have been bugging you from the start.

How To Disable Super Key In Ubuntu While Running Full Screen Apps

There are times when we use our Ubuntu systems for playing games, watching movies, or working on applications in full screen mode, and what we really don’t want while doing these activities is to accidentally trigger any form of distraction. One such distraction is the opening of Ubuntu’s Unity Dash when the Super (Windows) key is mistakenly pressed.

Of course, you can permanently disable the key to make sure that nothing happens when it is pressed, but that’s not the best solution given all you want is to prevent the key from doing anything when an application is running in full screen mode. Thankfully, there’s now a way – although not official – to disable the Super key only for full-screen apps.

Please note that the solution we’ll be discussing here has been tested on Ubuntu 16.04 LTS.

Disable Super Key

The tool that does the trick in this case is nothing but a small python script written by an AskUbuntu user Serg. To download and set up the script, execute the following commands:







+x sergrep

Once downloaded, the script can be executed in the following way (assuming that you are in the /opt directory):

python sergrep


The aforementioned command will not produce any output on the terminal.

But it will do what it promises – prevent Super key from opening Unity Dash for full-screen applications.

The script also has a debugging option which can be enabled by changing line number 34 from debug = False to debug = True and running it from the command line again. The following screen shot shows the output the script produces when run with the debugging option enabled.

In the screenshot above, the lines beginning with the word “Disabled” were printed when I tried pressing the Super key while a full-screen application was running.

Keep in mind that the “disable_super_key” script only disables the Super key; it doesn’t prevent Super key combinations like “Super + L” from initiating any corresponding action. But that, I personally believe, should not be a major problem, as the accidental pressing of a key combination should be rare.

It’s worth mentioning that Serg also came up with a solution to make sure that the disabling of the Super key can be made workspace-specific. The solution, he says, is generic and basically consists of a wrapper script that executes the user’s command upon entering a workspace, and sends SIGTERM to it when the user enters a workspace not on the list. Sadly, however, the solution – as per my testing – doesn’t work on Ubuntu 16.04.


The “disable_super_key” script created by the author undoubtedly is a very good solution to the problem it caters. It’s really easy to download, install, and execute. Needless to say, you can always make the script start automatically when logging in to make things more convenient.

How To Delay Startup Application In Ubuntu

If you’re using some apps every time you log in to your desktop, you can avoid having to run them manually every time by adding them to the startup list. However, if you set too many apps to autostart, your initial login to your desktop will lag significantly. All apps will be fighting for the same resources while trying to get to your desktop. Thankfully, there’s a solution: add a delay to startup applications.

In this tutorial, we show how to optimally delay startup applications in Ubuntu. We do this by adding a delay timer so that it doesn’t run automatically after login. Let’s see how you can do it for the apps you use.

Startup Applications

Some apps are helpful when they’re always available. However, some apps, in this case Plank, don’t autostart by default when you login. The solution is to add it to the list of other apps that start automatically whenever you log in to your desktop.

Visit your apps menu, search for the Startup Applications app, and run it.

The Startup Application Preferences dialog will show you a list of all the apps that load automatically whenever you log in.

Note: some system-related apps are hidden by default in the Startup Applications Preferences list. However, we ignore them for this tutorial, since they don’t affect what we want to do.

Add New Startup Entry with Delay

6. Log out or restart your computer.

7. Your application will autostart after the delayed time.

That is how to delay startup applications in the latest versions of Ubuntu. Are you using a different approach for auto-starting your apps? You can also learn the shortcut keys for Ubuntu so you can access your applications faster.

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.

How To Adjust Brightness On Windows 10

One of the best ways to avoid or reduce eye strain and headaches while using your computer is to have the correct screen brightness.

For many Windows 10 users, using the brightness adjustment keys on their keyboards is a quicker way of manually adjusting the brightness level on their PCs. 

Table of Contents

If, for some reason, the keys fail to work as they should, there are other methods you can use to adjust brightness on your Windows 10 PC.

How to Adjust Brightness on Windows 10

You can adjust the levels of brightness on Windows 10 manually or automatically based on surrounding light, battery life, or using a power plan.

How to Manually Adjust Brightness

You can adjust brightness manually from the computer’s display settings, from your keyboard, or using the Windows Mobility Center.

Next, select Display and go to the Brightness and color section.

In the Device Manager window, select and expand the Display adapters category.

If you’re using a second monitor, change the brightness using the buttons on the monitor.

For this guide, we used a Lenovo laptop whose brightness adjustment keys are placed on the top row of the keyboard, next to the Print Screen key.

The Windows Mobility Center is an alternative way to manually adjust brightness on Windows 10.

From the Mobility Center window, use the Display Brightness slider to adjust the brightness to the level that’s comfortable for your eyes.

How to Automatically Adjust Brightness

You can adjust brightness on Windows 10 automatically by enabling the battery saver feature.

Select Battery and then go to Battery Saver Settings.

Next, check the Turn battery saver on automatically if my battery falls below checkbox, and then adjust the percentage battery level using the slider.

Check the Lower screen brightness while in battery saver checkbox as well.

How to Use Adaptive Brightness to Adjust Brightness

Adaptive brightness is a Windows 10 feature that automatically adjusts your display to match the lighting conditions of your surroundings. The feature does this by tapping into the ambient light sensors, and is therefore useful in conserving battery life.

If your device has a brightness sensor, the Change brightness automatically when lighting changes setting will be available, in which case switch it to On.

How to Adjust Brightness on Windows 10 Using Shortcuts

There are adjustment shortcuts you can use to adjust brightness on Windows 10.  One of these shortcuts involve opening the Action Center in the taskbar and adjusting the brightness slider to your preferred level.

To do this, select the Notification icon on the taskbar and then drag the brightness slider to the level you want.

Select Edit your quick actions.

Use Dark Theme 

If you find it uncomfortable spending hours in front of your computer because of screen brightness, you can enable the Windows 10 Dark Theme or use Night Light Mode.

Windows 10 Dark Theme is like dark mode and it helps reduce eye strain due to prolonged computer use. You can use the dark theme to display darker tones by customizing your computer’s color scheme, thus making it easier on your eyes.

The dark theme will be applied automatically to apps like Mail, Microsoft Store, Calculator, and settings menus, but you may not get it with all aspects of Windows 10. For non-Microsoft apps, you’ll have to enable dark mode in those apps.

Check out our guides on how to enable dark mode on YouTube, Google apps, or macOS dark mode.

Use Windows 10 Night Light Mode

Night Light is a Windows tool that applies a blue light filter to the display. The tool doesn’t change the brightness of your display, but provides a light-theme display, which also reduces eye strain.

In the Brightness and color section, select Night light settings.

Note: Devices that use Basic Display or DisplayLink drivers lack Night Light mode. Plus, the feature may not apply to all monitors where you have two or more monitors attached to your computer.

Select Turn on now to enable Night Light immediately.

You can also toggle Schedule Night Light to On. This allows you to schedule Night Light to be displayed automatically during a certain time of the day.

You’ll get two options when you schedule Night Light: Sunset to sunrise, which activates night light to automatically fade in and out from sunset to sunrise. This setting depends on your time zone.

Alternatively, select Set hours to set your custom Night Light intervals at your preferred hours. You can also use the Color temperature at night slider to specify the display range of your light.

Control Your Brightness Settings

We hope you’ve learned how to adjust brightness on Windows 10 to optimize your display for eye health and comfort.
