23 Best Things To Do After Installing Ubuntu 18.04 and 18.10

First of all, let me show my heartfelt greeting to all the users who have successfully installed the latest Ubuntu 18.10 ‘Cosmic Cuttlefish’ on your laptop or desktop. As you are a new user and installed a fresh copy of Ubuntu, I highly recommend you to follow this list of things to do after installing Ubuntu 18.10 ‘Cosmic Cuttlefish.’ Here I will be sharing all the tips that are tested and will not damage your system. But you may not follow all the things listed here except what you like most and seems useful for you.

Things To Do After Installing Ubuntu 18.10

Let me clear something about what to do after installing Ubuntu 18.10 ‘Cosmic Cuttlefish.’ It depends on how users want to use the system. For a developer or programmer, users might be installing a lot of editors, IDEs, Tools. For a gamer, users must look into installing games and configuring graphics card. For a graphics design, he or she may install Gimp, KritaInkscape, Karbon and so on. So it entirely depends on how the task needs to get accomplished or the different mindset of the various users.

Here I am going to share a list of things to do after installing Ubuntu 18.10 ‘Cosmic Cuttlefish,’ and it’s mostly a generic list which helps the users, especially new users, to get the best out of their new Ubuntu system.

1.  New Changes in Ubuntu 18.10 ‘Cosmic Cuttlefish’

This time Ubuntu 18.10 ‘Cosmic Cuttlefish’ comes with some minor changes. If you are using Ubuntu 18.04 LTS release then hardly you will find any difference except for some performance improvements and bug fixes. As usual, It comes with a set fantastic desktop environment – Mate, KDE or Gnome Desktop (default). Whatever may be the user- advanced or newbie, you must know the latest changes come from new Ubuntu 18.10 ‘Cosmic Cuttlefish’ desktop. I recommend you to watch a video made by and see what’s changes the latest Ubuntu has brought for you.

Though Ubuntu replaces Unity desktop environment with the Gnome desktop, you may find some similarity with Unity with left-hand Dock system, top panel, status menu, and new message and calendar menu.

2.  Enable Additional Repositories

Ubuntu doesn’t come, by default, with enabling additional repositories. Before updating and upgrading your Ubuntu system must allow the additional canonical repositories.  To do so, search for software & update. In the other software tab, enables “Canonical Partners.” Now close the window, ignore if it says reload.

Enable Additional Repositories

3.  Check for Update and Upgrade

Though you have installed the latest version of Ubuntu; there might be some updates for resolving bug fixes, security patches, and software update. It’s always better to have an updated system. To check the update and do upgrade, go to the Software Updater tool from the Applications Overview and follow the on-screen prompts. You can also the do the Ubuntu update and upgrade by using the command into the Terminal. Run the below command into Terminal, hit enter and provide the password for further process.

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade

If you get a question of “y/n,” then select “y” for completing the subsequent task.

4.  Install Latest Graphics Drivers

This step is a must to do if you want to play latest Ubuntu Games and do a high graphical designing task. All the modern Linux laptop and desktop comes with high processing performance and graphics card, so to get the best performances you should enable proprietary drivers. To install and see the availability of the proprietary drivers for your hardware, Applications Overview >>> Software & Updates >>> Additional Drivers >>> Install/Apply changes

5.  Customize Gnome Shell

The default settings app, which comes preinstalled, doesn’t offer much control over the system. If you want to change the system environment including fonts, window style, animation, GTK themes, icons, then you must install the Gnome Tweak Tool. Install it by running the below command.

sudo apt install ubuntu-restricted-extras

Here I recommend installing the free version of libavcodec also to avoid an issue while performing media task with video editors or transcoder. Use the following code.

sudo apt install libavcodec-extra

Moreover, to enable encrypted DVD playback, you have to install… “libdvd-pkg.”

sudo apt install libdvd-pkg

Ubuntu system offers a blue light filtered night mode option as like window 10 or Oxygen OS or iPhone. Implementing into the system is easy. Follow Settings > Devices > Displays and toggle the Night Light on.

  1. TLP and Laptop Mode Tools are not compatible with each other and could introduce instability if installed together. Install one, or the other.

  2. hey guys im running kubuntu 18.10, is the above aimed at me or is it aimed at ubuntu gnome not kde environment, im new to this so need all the help possible thanks.

    • Throw a K in front of Ubuntu and you will get the KDE variety. The rest still applies. You would not have any issues if you did install the Ubuntu extras it would just lack some of the KDE-specific items that are in the kubuntu-restricted-extras.

    • Andy, it’s good to see you have an opinion. But gaining root privilege from a non privileged user account is totally possible… So definitely no, being vulnerable to viruses does not mean you act dumb. It also means you run vulnerable software. Which is the case 100% of time for pretty much everyone. I mean you just don’t know it yet, that’s the problem. What is true is it requires deep knowledge, reading code, and exploit the right vulnerabilities, sometimes more than one of them to get to the point you want. Then it’s a matter of finding the right combination of vulnerabilities to get access to the root console. And that could totally be just browsing a legitimate website you know, and something intalls itself silently onto your system to mine cryptocurrencies. Obviously, without running the browser as root. And no that’s not just when you run an email server that you become vulnerable, that’s gross misinformation. That can be any connectivity to the external world. You’ll only be protected when disconnected.
      Now, you can try and convince yourself that thanks to your deep sysadmin knowledge, you are protected. You will probably discover you were bloody wrong the hard way at some point (which is not something I wish for you btw).

  3. Hi! Thank you very much! I’m a newbie of Ubuntu/Linux. And maybe you know, can I activated Dolby Audio in my notebook Lenovo Y70015ISK? Where is i can download driver for it?

  4. 4. Install Latest Graphics Drivers
    No need, the proprietary AMD drivers are the open source ones now, the majority of people don’t need to install anything.
    8. Third-party Media Codecs & Extras
    No need if you already checked the box during install for 3rd party drivers, codecs etc..
    16. Play Games on Ubuntu Linux
    Don’t forget about Lutris which enables you to play most Windows games.
    The rest of the list is fine..

    Office software I recommend “freeoffice 2016”
    Or there’s “onlyoffice”
    Or “wps office”
    All of the above are compatible with MS formats and 100% free..or you can just use the online version of MS office which is free too.

    • This isn’t quite correct. I mean, you make it sound like everyone is using AMD (and thus ATI graphics cards). There are probably more people using Nvida than ATI.

      ATI *does* have proprietary drivers for newer cards. If you are not an OSS zealot then you will want to install them.

      Nvidia has always had great proprietary driver support for Linux. I used AMD+ATI on a few laptops for several years until their business decision forced me into new hardware. I chose to go back to Intel+Nvidia.

      You see, a while back ATI abandoned their proprietary Linux support for older graphics cards. If your using one of those cards then you no longer have a choice: you must use the open-source drivers and lose out on acceleration and other proprietary enhancements.

      • I always used the open-source drivers when I was using my AMD graphics. I’m currently using and Nvidia card, and when I installed Ubuntu 19.04 it installed the Nvidia driver without asking me. I don’t really care, but I have no need for acceleration. I don’t know (yet) of any Linux games that would require it.
