7 Essential Things To Do After Installing Arch Linux êŽë š
Brief
This tutorial shows you a few essential things to do after installing Arch Linux. This will help you get started with Arch Linux so that you can explore it further.
Earlier I showed you how to install Arch Linux. Today, I am going to list a few basic and yet important things to do after installing Arch Linux.
By this time, you probably already know that Arch Linux comes with a minimal installation and lets you build your own system on top of it. From installing desktop environments to media codecs and your favorite applications, everything has to be done by you.
This do-it-yourself (DIY) approach is what many Arch Linux users prefer. If you want things running out of the box, you should use Manjaro Linux. Manjaro is based on Arch minus the hassle.
Cutting down the chit-chat, letâs see what to do after installing Arch Linux.
Must to do things after installing Arch Linux
While at Itâs FOSS, we focus on beginner centric approach and hence we suggest plenty of GUI based approach, this wonât be the case here.
Arch Linux is sort of expert domain and we believe if you use Arch, you are not afraid of using the terminal. This is why the steps mentioned here are command line based.
0. Update your system
You might already have used the latest release, but itâs advisable to check for the latest update for your Arch System:
sudo pacman -Syu
1. Installing X server, Desktop Environment and Display Manager
Before installing a desktop environment (DE), you will need to install the X server which is the most popular display server.
sudo pacman -S xorg
Once itâs completed, use any of the below commands to install your favorite desktop environment.
sudo pacman -S gnome gnome-extra # To install GNOME:
sudo pacman -S cinnamon nemo-fileroller # To install Cinnamon:
sudo pacman -S xfce4 xfce4-goodies # To install XFCE:
sudo pacman -S plasma # To install KDE:
sudo pacman -S mate mate-extra # To install MATE:
You will also need a display manager to log in to your desktop environment. For the ease, you can install LXDM.
pacman -S lxdm
Once installed, you can enable to start each time you reboot your system.
systemctl enable lxdm.service
Reboot your system and you will see the LXDMÂ login screen, select your desktop environment from the list and login.
This is how my system looks like with LXDM and GNOME.
2. Install an LTS kernel
Why should you install LTS kernel in Arch Linux when it is supposed to be cutting edge?
Installing an LTS kernel means you have a more stable kernel with better support to older hardware. Also, the LTS kernels are supported for at least 2 years with bug fixes and performance enhancements.
If you rather choose to use the latest Linux kernel, you may find regression and bugs introduced by the latest kernel updates to your existing software and system. Itâs not a certainty but it is definitely a possibility. For example, a Kernel update broke GNOME in Arch based Linux some time back.
This is why it is advisable to use an LTS kernel if you prefer a more stable system and/or have an older one. But the decision is yours to make.
Before you install an LTS kernel, check the Linux kernel version you are using.
uname -r
To install the LTS kernel and Linux LTS headers, type the below command:
sudo pacman -S linux-lts
sudo pacman -S linux-lts-headers
At this point, the LTS version is the default one.
Once done, you can remove the older kernels by typing the below command. However, I prefer to keep it in âcaseâ something goes wrong, I can boot into the other Linux kernel version.
sudo pacman -Rs linux

3. Installing Yaourt
Yaourt stands for Yet AnOther User Repository Tool which can be used to search, download and install packages from the official repository as well as AUR.
Arch User Repository or AUR is a community-driven repository for Arch users and contains package descriptions to compile a package from source and install it. Most of the packages that make to the official repository start in the AUR first. Users contribute their own applications which are voted for or against and once it becomes popular enough, they are included in the official repository.
AUR contains lots of useful applications that are not found in the main repo can be installed from AUR with help of Yaourt. Yaourt is similar to what Synaptic Package Manager does, and can be installed by following these steps:
Open /etc/pacman.conf file and add these lines at the bottom:
[archlinuxfr]
SigLevel = Never
Server = http://repo.archlinux.fr/$arch
Save the change. Install Yaourt with the below command
sudo pacman -Syu yaourt
Use the command below to sync Yaourt with AUR:
yaourt -Syy
To install AUR packages, you can the below commands :
yaourt -S package-name
4. Install GUI Package Manager Pamac
The default package manager for Arch Linux is Pacman (Package Manager) and using Pacman is quite easy to install or remove a software.
However, itâs sometimes difficult to talk in commands. Pamac provides a GUI option for Pacman and works like Synaptic Package Manager or GNOME Software.
Pamac serves as a GUI tool for installing or updating packages and works well with Arch User Repository AUR.
How to install Pamac
Before you can use Pamac, you will need to have Yaourt (or Packer) installed first. Once done, type the below command in terminal to install Pamac.
yaourt -S pamac-aur
You can launch the GUI by searching for Add/Remove Software. It will show different packages that are available and installed and which all updates are needed.
However, by default, the AUR packages are not enabled. To enable it, click on the options just beside the search option) and choose Preferences. Under the AUR tab, Enable AUR support.
Installing software through Pamac is as easier as searching it through the GUI (which searches the community and AUR) and installing it with a click.
5. Installing Codecs and plugins
Of course, you are going to use your personal system for recreational works like watching videos and listening to your favorite song. But before that, you will have to install codecs for these audio and video files.
Type the below command in the terminal:
sudo pacman -S a52dec faac faad2 flac jasper \
lame libdca libdv libmad libmpeg2 libtheora \
libvorbis libxv wavpack x264 xvidcore \
gstreamer0.10-plugins
However, installing a media player like VLC imports all the necessary codecs and installs it.
sudo pacman -S vlc
You may add a music player too:
sudo pacman -S amarok
6. Installing productive software
For day to day use and setting up your Arch system for productive use, you need some basic applications like an office suite, email client, a web browser etc.
sudo pacman -S libreoffice thunderbird firefox gedit flashplugin \
skype dropbox aria2
Aria2 is a download manager, LibreOffice is the most popular open source office suite, Thunderbird is a cross-platform mail and chat client, Firefox is an open source and free web browser, Gedit is an editor, flashplugin installs flash, Skype is a popular messaging and video calling software and Dropbox â to store your file for anytime access.
Along with these, you will need archive managers
sudo pacman -S p7zip p7zip-plugins unrar tar rsync
This is of course just a suggestion. You can install essential Linux applications of your choice and your requirement.
7. Customizing the looks of your Arch Linux desktop
You can customize your Arch Linux by installing some nice flat themes or the conky monitoring tool.
Some of the most liked themes are Arc GTK, flatplat, Vertex and Numix, which can be installed by below command:
yaourt -S arc-gtk-theme flatplat-theme-git vertex-themes
sudo pacman -S numix-themes
Go to settings > Appearance and change the default theme from there.
Conky is a free system manager application which can monitor and display memory usage, CPU statistics, disk storage, swap, CPU temperature and more.
To install conky, use below command :
sudo pacman -S conky
You can configure conky yourself which will need some digging into the ~/.conkyrc file or you can download your favorite one from web and replace the default conkyrc file. There is a detailed tutorial about conky and its configuration on the Arch Linux website.
Additional tip
At any point in time, if you feel like removing any application (and its dependencies), you can use these commands:
sudo pacman -R package-name
It removes the package without removing the dependencies. If you want to remove the dependencies but leaving out the ones which are being used by some other application, below command will help:
sudo pacman -Rs package-name
Final Words
Arch Linux is a great distribution if you want to take control of everything, from setting up your favorite desktop environment to the tools you want to use. The Arch Wiki is a great place to learn these things and in itself more than sufficient.
In this article, we have just listed out the most important things to do after installing Arch Linux. The rest is up to you to explore.
