Ubuntu Desktop vs Ubuntu Server: What's the Difference?

Ubuntu is one of the most widely used and popular Linux distributions, that comes in multiple editions including Ubuntu Desktop, Ubuntu Server, and Ubuntu Core to mention a few.

Ubuntu Desktop is a perfect choice for novices or users who are getting started out with Linux owing to its neat and intuitive user interface and default apps to help users get started.

Ubuntu Server is built for server environments, which is a lightweight and minimalistic version that is stripped off of any GUI applications and elements to enhance the speed and performance of running production-grade applications. It can serve as a web server, file server, development server, and DNS server to mention a few use cases.

In this guide, we will review some differences and similarities between these two Ubuntu editions.

Differences Between Ubuntu Desktop and Ubuntu Server

In this section, we are going to explore the differences between Ubuntu Desktop and Ubuntu Server based on the following parameters:

Ubuntu Graphical User Interface (GUI)

One parameter distinguishing Ubuntu Desktop from the Server is the presence of a Graphical User Interface, which provides a desktop environment out of the box. Unity has been the default environment for the longest until the introduction of Ubuntu 18.04 (Bionic Beaver) which was the first Ubuntu desktop edition to feature GNOME desktop.

The GUI allows users to interact with the operating system using Windows, widgets, menus, icons, and other graphical elements. It’s more intuitive, especially for beginners and users who are not adept at the (CLI) command line interface.

The administration of the Ubuntu desktop is pretty straightforward since the interaction is via the graphical interface. In addition, you can install remote software tools such as TeamViewer, AnyDesk, and VNC Viewer to remotely connect to your system.

On the other hand, Ubuntu Server provides minimal installation and lacks a graphical interface. Administration of the server is mostly via CLI through SSH protocol. However, you can install web-based server-management tools such as Cockpit, Webmin, and Ajenti that will allow you to remotely administer your server on a browser.

Ubuntu Memory Footprint

Ubuntu Desktop ISO image is quite big (4.6GB for Ubuntu 22.04) given the sheer number of software packages, libraries, and utilities that it bundles with by default. Therefore, ensure you have ample disk space when downloading the desktop version.

Ubuntu Server has a relatively small memory footprint (1.8GB for Ubuntu 22.04) for obvious reasons. It packs fewer software packages and utilities compared to the desktop edition.

Ubuntu Pre-Installed Software

Another major difference between Ubuntu Desktop and Ubuntu Server is in the number of pre-installed software applications.

Ubuntu Desktop ships with a vast array of pre-installed applications in almost every domain. Some of the applications you get out of the box include:

Firefox Web browser
LibreOffice suite
Nautilus File Manager
Thunderbird Email Client
Screenshot Tool
Multimedia app for watching videos, and playing mp3 files.
Basic apps such as Calculator, Calendar, weather app, etc.

The Ubuntu Server is a stripped-down version of Ubuntu Desktop and only provides a handful of pre-loaded applications and software stacks that you can choose to install during installation, which includes:

OpenSSH server
LAMP server
DNS server
Print server
Tomcat Java server
Samba File server
PostgreSQL database

Ubuntu Resource Utilization/Performance

As we have already seen, Ubuntu Desktop comes with a whole lot of pre-installed GUI applications, some of which might be considered bloatware if you are never going to use them at all.

The GNOME desktop environment is notorious for high CPU and RAM usage which can sometimes lead to degraded performance.

Firefox browser alone is known to cause sustained high resource usage in processing and displaying web content. For this reason, the Ubuntu desktop is not the right pick for server environments as high resource overhead will impact production-grade applications.

Ubuntu Server is stable and runs smoothly for the most part. It’s devoid of bloatware and you get to choose which applications and services to run. Thus, it records better performance than the Ubuntu desktop and is a great choice for running enterprise applications.

Ubuntu System Requirements

Due to its lightweight and minimalistic nature, the Ubuntu server‘s recommended installation requirements are slightly lower compared to Ubuntu Desktop. Here is a comparison of the two.

Ubuntu Server

1 GHz CPU or higher
1GB RAM or more
4.0 GB of hard drive space or higher

Ubuntu Desktop

2 GHz CPU or higher
4 GB RAM or more
GPU: VGA capable of 1024×768 screen resolution
25 GB of hard drive space or higher

Similarities Between Ubuntu Desktop and Ubuntu Server

Having looked at the differences, let us now explore the similarities between the two.

Ubuntu Maintainer

Both Ubuntu Server and Ubuntu Desktop are actively maintained by Canonical and get updates, bug fixes, and patches from the same company.

Ubuntu Software Repositories

Ubuntu Desktop and Server share the same application repositories. To be more specific, these include Main, Multiverse, Universe, and Restricted.

Ubuntu Package Management

Both editions use the APT package manager which handles dependencies quite well during the installation of software packages. However, Ubuntu desktop also provides Software Center which is a GUI package manager that allows users to install and manage packages without running commands. Another popular GUI package manager is Gdebi.

The dpkg package manager is also used by both editions to install .deb packages from external sources other than the main repository.

Ubuntu Desktop provides Gdebi which is a tiny app that helps users install .deb files efficiently by handling dependencies.

Ubuntu Kernel Build

If you’ve been wondering whether Ubuntu desktop and server use the same kernel, then the answer is a resounding YES. This has been the case since the release of Ubuntu 12.04 LTS.

Ubuntu Support

Every Ubuntu LTS release enjoys 5 years of standard support and this includes critical security fixes and patches as well as ongoing app updates.

You can check your Ubuntu support [EOL – End of Life] from the command line as shown.

$ hwe-support-status --verbose

When Should You Use Ubuntu Desktop and Ubuntu Server?

Ubuntu Desktop is typically what you would go for if you intend to run a desktop operating system that provides a wide collection of apps and utilities for everyday use. Whether it’s office productivity, graphic design, video editing, or multimedia, Ubuntu Desktop is no doubt the right choice.

If you intend to host mission-critical applications, the Ubuntu server is recommended due to its great performance and stability. Its minimal nature ensures that most of the system resources are allocated to running intensive applications without service degradation.

You can comfortably run a web server, microservices using Docker and Kubernetes, and a myriad of other software stacks.

Conclusion

In this guide, we drew a comparison between Ubuntu Desktop and Ubuntu Server and flushed out the major differences and similarities between the two.

Typically, Ubuntu Desktop is a hot pick for home users and everyone who enjoys the appeal and elegance of a desktop environment. The server edition is majorly reserved for server workloads.

The Power of the Select Command to Automate Tasks in Bash

by George Whittaker

Introduction

The select command in Linux is a versatile tool primarily used for menu creation in bash scripts. The command retrieves data from a specified list, which can be an array or other data source, and generates a menu from this data. Depending on the complexity of your task, you can create various types of menus such as a menu based on directory list or even a menu derived from file content.

Basic Syntax

The basic syntax of the select command is as follows:

select v in data_list

do

statement1

statement2

statement3

done

Here, each menu item is created from the data_list. The data retrieved from this list is stored in a variable to create the menu. You can also use the select command with the case command to create more complex menus.

Creating a Simple Menu

In a simple scenario, you might want to create a menu of mobile brands. You can easily achieve this by creating a bash file with the select command. After executing the script, the user will see a menu of brands and be asked to choose one. The name of the selected brand will then be printed on the screen.

Using Select Command with a Case Statement

To create a bash menu with a case statement, you can use the select command in conjunction with a case statement. After running the script, the user selects any menu item, and the case statement will match the selected value with its cases. If none of the case values matches the selected menu item, the script will print an “Invalid entry” message and terminate.

Creating Nested Bash Menus

The select command can also be used to create nested menus. This involves creating a menu under another menu. You can implement nested menus using two or more select and case statements. In this case, the parent menu contains multiple items and a sub-menu contains additional items. When a user selects an item, the script will display the corresponding message or submenu.

Creating a Bash Menu with an Array

Arrays in bash can store multiple data points, making them an excellent data source for creating bash menus. You can use an array with the select statement to create a menu. In this scenario, a bash subroutine is used to create a menu from the array. The script will check if the selected menu item number is within the appropriate range. If it’s not, the script will prompt the user to select a number within the valid range.
