How to Install Desktop (GUI) on Ubuntu 24.04
Ubuntu Server is a server-focused operating system that conserves resources by not providing a graphical user interface (GUI) in the default installation. However, users have the flexibility to install a desktop environment (DE) and graphical tools when needed.
The default Ubuntu Desktop is a version of the GNOME desktop environment customized to integrate well with Ubuntu's ecosystem.
KDE Plasma is a flexible and customizable Qt-based desktop environment that provides visual consistency and style while remaining fast and responsive. Plasma is the default DE of Kubuntu, a popular Ubuntu flavor.
XFCE is a lightweight desktop environment known for its speed and efficient resource usage. It is the default DE in Xubuntu, an official Ubuntu flavor designed to work on older, less powerful hardware.
MATE is a fork of GNOME 2 and a popular graphical interface designed to be light on resource consumption.
LXQt is another Qt-based desktop environment featuring a lightweight GUI that minimizes the impact on system memory and CPU. The official Ubuntu flavor featuring this DE is called Lubuntu.
