Linux: The Ultimate Guide

User Interface: The Raspberry Pi OS desktop, PIXEL, looks similar 
to most common desktops, such as macOS Microsoft Windows, and 
is based on LXDE. The menu bar is set up and contains an applica-
tion menu with Terminal, Chromium, and File Manager shortcuts. 
A Bluetooth menu, a Wi-Fi menu, a volume controller, and a digital 
clock are to the right.

Package Management: Packages can be installed using APT, the 
Recommended Software application, and the APT GUI cover 
through the Add/Remove Software tool.
3. 
Components: PCManFM is a file browser that allows quick access 
to all computer locations and is redesigned for Raspberry Pi OS 
Buster (2019-06-20). Raspberry Pi OS initially used Epiphany as a 
web browser but switched to Chromium by launching its redesigned 
desktop. Raspberry Pi OS comes with many basic IDEs, such as 
Thonny Python IDE, Mu Editor, and Greenfoot. It is also shipped 
with educational software such as Scratch and Bookshelf.

free software program without patent software or firmware and uses 
a version of Ubuntu’s modified kernel, with non-free code (binary 
blobs) removed. Trisquel relies on user contributions. Its logo is 
the triskelion, a Celtic symbol. The Free Software Foundation lists 
Trisquel as a distribution containing only free software.
History
The project started in 2004 with Vigo University’s support for Galician 
language for educational software. It was officially launched in April 2005 
with Richard Stallman, founder of the GNU Project, as a special guest. 
According to project director Rub
én Rodríguez, Galician’s support has 
sparked interest in South American and Mexican communities of immi-
grants from Ourense Province. In December 2008, Trisquel was added 
by the Free Software Foundation (FSF) to its Linux-approved list of Free 
Software Foundation distributions.
