GNOME Flashback: a classic touch for your Linux desktop

GNOME Flashback can be giving your modern computer a retro makeover. It changes how your desktop looks and feels to resemble those older versions of GNOME. Choose Flashback if you find the newest GNOME desktop confusing or prefer the classic style. GNOME Flashback has a panel at the bottom of the screen, a traditional start menu, and different ways to manage your windows.

Upgrading GNOME on Debian

The stable version of Debian often comes with an old GNOME version due to its focus on stability. For example, GNOME Debian 12 latest update comes with GNOME 43. The newest version of GNOME, as of writing this post, is 46. The latest versions of GNOME loaded so many innovative features. Debian 12 users can't simply update to GNOME 46. Here are the steps to update to GNOME's latest version. Debian 12 is used to demonstrate the update process. I request that the process be tried in a Debian 12 installed in Virtualbox for learning purposes and later tried on the production computer. Take the data backup before the update attempt.

Two ways we can do the GNOME update. Install the Debian 12 without any desktop. While software selection, uncheck the Debian Desktop environment and GNOME to get desktopless Debian.

Start the installation directly if you are using the Debian stable version with a desktop. Anyway, start the update process from here.

How to update Linux kernel in Debian

Debian is a Linux-based operating system. The Linux kernel is the core component of any Linux-based operating system, acting as a bridge between the hardware and the software. It manages critical tasks such as memory allocation, process scheduling, device drivers, and file system interactions. Linux kernel development is an active process. The Linux kernel may be old if you use the stable version of Debian. Updating your Linux kernel is crucial for security, performance, and hardware compatibility. For example, the Debian 12 stable version consists of Linux kernel version 6.1. Debian repository contains the latest Linux kernel version and can be installed in the system. The following are the procedures for updating the kernel from the stable version of Debian to the new one.

Check the current kernel version

Apply the following command in the terminal to see the kernel version.

uname -r

Ubuntu without Snap: finding Freedom in alternative distros

Since Ubuntu introduced Snap, people using Linux have been arguing about it. Snap is supposed to make installing and updating software easier, but it also has some problems. These problems make some people think about switching to other Linux versions based on Ubuntu.

Snap packages are like self-sufficient boxes. They have everything they need to work inside them, so installing and updating them is simple. This makes things easier for people who are new to Linux. Also, because they're isolated, they're less likely to mess up other programs on your computer.

Snap is controlled by the company that makes Ubuntu. This means they have a lot of power over what software is available. Some people don't like this because they feel it limits their choices.

Snap packages can be slower than the older way of installing software (.deb packages). This is because they are isolated and need extra resources to run. Snap can also make Ubuntu take up more space on your computer and slow it down.

Because of Snap's problems and the fact that one company controls it, some people are switching to other versions of Linux that are based on Ubuntu but don't use Snap. These other versions are a good way to experience Linux in a more basic way, with popular desktop environments like GNOME, XFCE, and Cinnamon. Here is a hand-picked list of Ubuntu-based systems without Snap:

Pop!_OS: Developed by System76, Pop!_OS is known for its polished GNOME desktop. It offers a good user experience, focuses on productivity, and has excellent hardware compatibility, making it a popular choice for developers and creators.

Voyager Linux: Voyager, hailing from France, is based on GNOME and features a beautiful, modern design. It emphasizes simplicity and ease of use, making it suitable for both newcomers and experienced Linux users.

Linux Mint: One of the most user-friendly Linux distributions based on Cinnamon desktop. Linux Mint provides a familiar Windows-like interface and a focus on stability. It's a great option for those transitioning from Windows or seeking a hassle-free experience.

Xubuntu: A lightweight Ubuntu flavour using the XFCE desktop environment, Xubuntu is ideal for older hardware or systems with limited resources. It offers both full and minimal desktop editions.

Rhino Linux: A relatively new distribution based on Ubuntu with XFCE desktop, Rhino Linux focuses on providing a clean, modern, and user-friendly experience.

Linux Lite: Designed specifically for older hardware and users transitioning from Windows, Linux Lite offers a lightweight and intuitive experience. It prioritizes simplicity, ease of use, and compatibility.

Elementary OS: A visually appealing and user-friendly distro inspired by macOS. It focuses on simplicity and a cohesive design language.

Some of these Linux versions might let you use Snap if you want, but they usually use the usual .deb way of installing software. This list is a good place to start if you want to try Ubuntu-based systems that don't depend too much on Snap.
