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.
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.
Undoubtedly, Ubuntu 22.04 LTS’s black screen after suspend issue has been a critical problem for some users. If you have an NVIDIA or AMD graphics card, you may find this issue more frequently. This article provides an in-depth analysis of the problem and provides various solutions.
If you’ve been dabbling around with the Linux operating system, especially Ubuntu, you might have noticed numerous loop partitions appearing in your system. Often ranging in small sizes such as a mere few megabytes, you might wonder why these partition systems exist, what purpose they serve, and if they can be deleted to reclaim disk space.
Harnessing the power of NVIDIA GPUs on Debian and Ubuntu systems often requires navigating a maze of configurations and dependencies. NVIDIA’s CUDA Toolkit, essential for GPU-accelerated tasks, can simplify this with Docker. By containerizing the toolkit, developers ensure a consistent, streamlined, and optimized environment across systems. In this guide, we’ll detail the steps to seamlessly integrate the CUDA Toolkit within a Docker container for these popular Linux distributions.
