Most Linux systems tend to use a little bit of storage on the hard drive as swap space, where temporary files can be stored by the system and then easily recalled later. This speeds up operations, without needing to take up any space inside of the physical memory (RAM). On a Raspberry Pi, this same convention can prove problematic due to the majority of devices relying on an SD card as the primary (or only) storage device.
VNC is one of the primary ways used to remotely control a Raspberry Pi. Since most users do not use the Raspberry Pi like an everyday PC, and therefore may not even have a monitor and other peripherals connected to it, being able to control the Raspberry Pi from another device comes in handy. Another common way to remotely administer a Raspberry Pi is by setting up SSH.
Setting a static IP address for your Raspberry Pi will ensure that the device can always be accessible at the same IP address on your network, since it will never change. This is ideal for a Raspberry Pi being used to host a service such as a gaming server, web server, etc. It makes it more convenient when applying network configurations, since you know that the Raspberry Pi can always be found at the same, predictable IP address.
The latest Raspberry Pi models have WiFi chips built in that allow the device to connect to a wireless network. If you are connected to WiFi on your Raspberry Pi, but experiencing poor speed or dropped connections, it is time to check the WiFi signal strength to begin troubleshooting the issue. Generally, the little WiFi chip built into Raspberry Pi 4, Raspberry Pi 3, or Raspberry Pi Zero W models is about as strong as the one you would find in your mobile phone, but checking the signal strength will tell you if you are close enough to the router or hotspot.
It is always a good idea to keep an eye on the temperature of your Raspberry Pi’s CPU. Although this small processor packs a punch for its size, it is important to remember that it does not have a fan or any other cooling ability by default. That means that if the processor is constantly working hard, CPU temperatures could get high and eventually damage the device.
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.
During regular software updates in Ubuntu Linux distros, you may encounter a situation where some packages have been kept back and are not updated. This could lead to disparities in the version of packages across different systems.
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.
In this article, you will learn how to install the Nvidia driver on Debian 12 “Bookworm” from the standard Debian repository. If, for some reason, the installation of the Nvidia driver from the standard Debian repository fails, or if you wish to have a more up-to-date Nvidia driver, this tutorial will also guide you on how to install the official Nvidia driver directly from the Nvidia.com website.
Since all the major Linux distributions adopted Systemd as their init system, they progressively became more and more similar to each other. Void Linux is an exception: it was written from scratch entirely by volunteers, uses Runit as its init system and service manager, and, as its name may suggest, it was designed with simplicity in mind.
Fdisk, cfdisk and sfdisk are command line partitioning utilities included by default in all Linux distributions. They provide different interfaces to the same set of functions: while they all can be used interactively, only sfdisk is script-oriented. They support DOS, GPT, SGI and SUN partition tables.
Despite its small size, the Raspberry Pi is perfectly capable of putting out audio via HDMI, Bluetooth, or analog audio with the 3.5mm onboard headphone jack. If you have just set up your Raspberry Pi and need to perform some testing to get the audio working correctly, or verify that your setup is working, then there are easy ways to test the audio on Raspberry Pi. In this tutorial, you will see how to test audio functionality on a Raspberry Pi.
