All of the latest Raspberry Pi models have Bluetooth built in, giving users another medium by which they can connect their peripheral devices such as headphones, keyboard, mouse, etc. Ideally, Bluetooth devices should be easy to connect to your Raspberry Pi. The connection process usually involves making your peripheral device discoverable, and then selecting the devices from the Bluetooth list on your Raspberry Pi.
When it comes to remotely accessing your Raspberry Pi, you have a lot of options available, such as SSH and VNC. Yet another option available would be xrdp, which is the open source implementation of the Remote Desktop Protocol (RDP). RDP is commonly used on Windows systems, where it is installed by default, and other operating systems also like to implement this protocol in some capacity due to its widespread use and reliability.
SD and microSD cards are not known for their speed, but their slim size makes them the default choice for storage in the Raspberry Pi. Most users will install the Raspberry Pi OS to a microSD or SD card, and then use additional hard drives if the need for greater read and write speeds arises. In order to use an SD card or microSD card for storage on the Raspberry Pi, it should pass the benchmark test for minimum speeds.
Ubuntu’s distributions, starting from version 22.04, have started packaging Firefox as a Snap package. Snap packages are Ubuntu-specific, containerized software packages that include dependencies needed for the software to run. However, due to personal preference or issues regarding their functionality, some users may prefer to install Firefox as a traditional Deb package.
Ubuntu provides its users with two display servers: “Wayland”, the default display server and “Xorg” (also known as X11 or just “X”). Both display servers crucially stand at the connection point between your physical, computational resources and the graphical user interface (GUI) you interact with.
One of the most common ways for users to access and administer their Raspberry Pi is via a VNC connection. VNC allows users to control their Raspberry Pi remotely, and interact with the desktop environment as if they were sitting directly in front of the Raspberry Pi, with a monitor and other peripherals plugged in. In reality, the Raspberry Pi needs nothing more than an Ethernet or Wi-Fi connection to facilitate VNC connections and full access to the system’s desktop.
Since a Raspberry Pi is commonly used as a test system rather than part of a production environment, you may not need any kind of advanced security on the device. For example, you may get tired of typing your password every time you want to log in to the Raspberry Pi, and wish to bypass these prompts completely. Doing so would be inherently less secure, but in some situations, flouting the security convention may be irrelevant. It is possible to bypass both the GUI and/or console login prompts on the Raspberry Pi.
Once you get your Raspberry Pi booted up and have the monitor plugged in via HDMI, you may need to manually set the resolution to get things looking how they should on your screen. The Raspberry Pi OS makes this pretty easy to do from the GUI menus, and also gives us the option to configure headless resolution for VNC connections. So, even if you do not have a screen plugged into your Raspberry Pi, we can still configure the resolution for remote connections. In this tutorial, you will see how to set the resolution on a Raspberry Pi.
GNOME is the default desktop environment for Ubuntu 20.04. If you don’t yet have a desktop environment installed (as is the case for Ubuntu Server), or have a different GUI and would like to switch to GNOME, it’s very easy to do. GNOME includes a variety of desktop applications and its aim is to make a Linux system easy to use for non-programmers. In this tutorial, you will learn how to install the GNOME desktop environment on Ubuntu 20.04 Focal Fossa Linux.
The purpose of this tutorial is to install a desktop environment GUI on Ubuntu 20.04 Focal Fossa, whether you already have a GUI installed and wish to use a different desktop environment, or if you are only using the command line and would like access to a GUI. You can also use these instructions to install a GUI on Ubuntu Server 20.04, which doesn’t have a desktop environment installed by default. Follow along with our instructions below to install a GUI on Ubuntu 20.04 Focal Fossa Server and Desktop.
In order to enable root login for Kali Linux, we must set the the root password manually. In past versions of Kali Linux, users were able to log in directly to the root account by default. On more recent versions, this has been disabled. The reasoning behind this change should be obvious, but if you’re a Kali user, you probably know your way around a Linux system by now, and there’s not much risk in letting you use the root account to log in.
