Lubuntu is a Linux distribution that combines the Ubuntu framework with the lightweight LXQT desktop environment, making it fast, reliable, and user-friendly, particularly for older hardware. The desktop interface is designed to be familiar to users, especially those accustomed to Windows, featuring a panel, start menu, system tray, and organized applications. The Configuration Center allows users to customize settings easily. Openbox is the default window manager, enabling theme and window behavior modifications. Lubuntu does not provide a straightforward method for sharing folders across a local area network using its default file manager. The operating system is notably fast, with applications launching quickly, making it a suitable alternative to Windows 10 for older machines.
