Good news for GNOME fans as Adaptive Sync displays come to Mutter

Submitted by Rianne Schestowitz on Thursday 9th of June 2022 09:42:31 AM Filed under
GNOME

In a sign of how display handling is evolving, the GNOME desktop's 3D-compositing Mutter window manager is gaining support for variable refresh rate (VRR, also known as Adaptive Sync) displays.

Mutter is an important chunk of code. As the project page says, it's "a Wayland display server and X11 window manager and compositor library."

It's the basis of GNOME Shell, which is implemented [PDF] as a Mutter plug-in, but other desktops use it as well.

For instance, the PIXEL desktop of the Raspberry Pi OS.

It's also used in Pop!_OS's Cosmic desktop. Cinnamon uses a fork of it called Muffin.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
