The Truth they are not telling you about “Themes”

Filed under
GNOME

Before we start, let’s get this out of the way because the week long delirium on social media has dragged enough.

Yes, libadwaita “hardcodes” Adwaita. Yes, applications, as is, will not be following a custom system theme. Yes this does improve the default behavior of application for GNOME when run on other platforms like Elementary OS. However, this is was the result of a technical limitation, and not some evil plot as Twitter will keep telling you…

The reason is that in order for High Contrast (and the upcoming Dark Style) to work, libadwaita needs to override the theme name property so it doesn’t fallback to GTK’s “Default” High Contrast style. The “Default” style is an older version of Adwaita, not your system style.

Compared to GTK 3, there isn’t a new way to enforce the “hardcoded” style. The GTK_THEME variable still works, as does gtk.css and probably 3 other ways of doing this. Likewise, if you are developing a distribution, you have control of the end product and can do anything you want with the code. There is a plethora of options available. Apparently complaining on social media and bullying volunteers into submission was one such option…

And I guess this also needs to be stated: this change only affects apps that choose to use libadwaita and adopt the GNOME Design Guidelines, not “every” GTK 4 application.

As usual, the fact that the themes keep working doesn’t mean they are supported. The same issues about restyling applications when they don’t expect it apply and GNOME can not realistically support arbitrary stylesheets that none of the contributors develop against and test.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
