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. In addition, it has no animation and does not consume much computer resources.

How to get GNOME Flashback

Existing Linux-based operating systems users can install GNOME Flashback desktop. Apply the following commands to the terminal to install it in Debian / Ubuntu-based operating systems:

sudo apt update
sudo apt upgrade
sudo apt install gnome-session-flashback

Reboot system. From the login screen, just look for the little gear icon next to your name on the login screen, and choose "GNOME Flashback" from the list.

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
