Most people do not understand the knowledge points of this article "how to optimize Ubuntu16.04 performance", so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "how to optimize Ubuntu16.04 performance" article.

Ubuntu 16.04 is a long-term supported version (LTS) that Canonical has promised to release for five years. In other words, you can let this version run on the computer for five years! In this way, it is particularly important to set it up in the first place. You should make sure that your software is up-to-date, installed with common applications, and easy to use.

1. Download updates

Now that you have installed Ubuntu, the first thing to do is to download the latest updates.

Start the Ubuntu software in the parking bar. The updates tab displays any updates available.

Or you can search for Software Updater (software updater) from Dash. The application checks Ubuntu's software library for changes. Click the install now button to install each update.

Click Details of updates (update details) to view the updates you want to download. You can uncheck any application you want to skip.

You may need to restart so that some changes will take effect.

two。 Install the driver

Next, make sure everything is running methodically. Some vendors provide proprietary drivers to ensure that the hardware runs properly. Without a driver, your wireless or video card may not run directly (in the case of a wireless driver, you also need an Ethernet cable to surf the Internet).

Canonical provides the advantage of easy access to these drivers. You just need to start "Software & Updates" (software and updates) to find these drivers. You can select the Additional Drivers (extra drivers) tab here. Additional proprietary drivers will appear here.

All right, you're done. This task is easier in Ubuntu than in some other Linux distributions.

3. Install the application

16.04 indicates that the Ubuntu software center no longer exists. You can now install applications from Ubuntu software (renamed Gnome software). In addition to updates, you can also install applications here.

Ubuntu software groups applications by category so that you can easily find the applications you need. If you already know what application you are looking for, just enter the name of the application in the search bar.

The Ubuntu software appears at the bottom of the parking bar. Click it to get essential or indispensable applications that are not pre-installed.

4. Add PPA

Some applications do not appear in Ubuntu software. The application may not meet the guidelines of Canonical, or it may not exist when Ubuntu 16.04 is released.

In any case, developers can use personal package archiving (PPA) to provide a Ubuntu version of the application.

You can add these applications simply by opening "Software and updates" and going to the "other Software" tab.

Here, click add. At this point, you can enter the address into the PPA you want to add.

Need further help? These applications usually come with their own installation instructions. You can often copy and paste the code into the terminal. Just make sure you trust the source and understand what you're copying. If the command is not run properly, it will cause damage to the computer.

5. Install the codec

Many of your audio and video files cannot be run directly. This is not so much a technical issue as a legal one. Canonical does not have permission to distribute codecs used to play most of the restricted formats that are part of Ubuntu.

On the other hand, Canonical can be redistributed after the codec is installed.

It's getting pretty complicated. We may need to write a whole article to discuss this problem.

The main points are as follows. In the United States, the clear legal way to use proprietary codecs is to buy codec packages. You can also download Ubuntu Restricted Extras and get all the excellent codecs, which is not officially approved in the United States, but you are unlikely to run into trouble. As for other countries, the law is different, it depends on which country you live in.

6. Change theme and wallpaper

I don't think the black panel is particularly ugly. However, the default appearance of Ubuntu is not eye-catching.

You can change the theme without installing anything extra. Go to system Settings > appearance. Here, you can change the default "Ambiance" theme to a more colorful one.

You can also change the desktop background here. Ubuntu comes with more than a dozen options. You can add more options by clicking the + button.

7. Adjust the starter

Want the starter button to be bigger? Think that sidebar takes up too much space? In any case, go back to system Settings > appearance, and you can make changes. 48 x 48 pixels is the default value, but you can move the slider to increase or decrease this number.

Starting from 16.04, you can move the initiator to the bottom of the screen. It takes a little more work to carry out this step. Do not want to install any additional software to achieve this step, need the support of the terminal.

Here, enter this command:

Gsettings set com.canonical.Unity.Launcher launcher-position Bottom

To move the initiator back to the side of the screen, just make this small change:

Gsettings set com.canonical.Unity.Launcher launcher-position Left8. Adjust the application menu

The Ubuntu application menu is usually invisible. To make them appear, you can move the mouse pointer over the panel. It's easy, as long as you know where to find it.

However, this requires additional mouse movement. You only need to adjust the mouse pointer to see what options are available.

Users who are familiar with keyboard shortcuts can avoid this problem by setting the menu to be always visible. This option appears under system Settings > appearance. This time, you have to select the behaviors tab.

You have several options. In addition to making the menu always appear, you can also change its location. Switching them to the window bar instead of the panel is a good way to retain old-fashioned functionality while having a different appearance.

9. Configure Dash

Dash is the centralized center of Ubuntu Unity. The top icon in the launcher opens the application, accesses files, and loads online search results. Is this excellent, or is it overqualified?

You can disable aspects you don't like. System Settings > installation and Privacy > Files and applications allow you to control whether Ubuntu records your file usage and access it through Dash and other places.

Maybe you want more results in Dash. Try to remove Amazon search results. This used to be the default behavior. Now, you have to enable this feature in system Settings > installation and Privacy > search.

10. Download the Unity tuning tool

Want to adjust other aspects? What about everything else? the Unity Sizing tool (Unity Tweak Tool) is your one-stop tool that can customize even the tiniest aspects of the Ubuntu desktop. Change the icon. Specifies the trigger angle that shows or hides the window. If you have anything else to worry about Unity, you can fine-tune it here.

For example, system Settings > appearance provides an option to automatically hide the initiator. The Unity adjustment tool allows you to change the animation during the animation.

Clicking the icon in the launcher will open the appropriate application. Click again to do nothing. What else can it do? If you switched to this distribution from another operating system, you can expect that the second click will minimize the application. You can enable this behavior in Ubuntu by clicking Unity tuning tools > Unity > initiators > minimize.
