GNOME 3.34 includes a number of new features and improvements. Congratulations and thank you to the whole GNOME community for the work that went into this release! Read on for more details.
The desktop itself has been refreshed with a pleasing new background. You can also compare your background images to see what they’ll look like on the desktop.
There’s a new custom application folder feature in the GNOME Shell Overview. It lets you combine applications in a group to make it easier to find the apps you use.
You already know that Boxes lets you easily download an OS and create virtual machines for testing, development, or even daily use. Now you can find sources for your virtual machines more easily, as well as boot from CD or DVD (ISO) images more easily. There is also an Express Install feature available that now supports Windows versions.
Now that you can save states when using GNOME Games, gaming is more fun. You can snapshot your progress without getting in the way of the fun. You can even move snapshots to other devices running GNOME.
A drop-down terminal lets you tap a key and quickly enter any command on your desktop. Often it creates a terminal in a smooth way, sometimes with effects. This article demonstrates how it helps to improve and speed up daily tasks, using drop-down terminals like Yakuake, Tilda, Guake and a GNOME extension.
Yakuake is a drop-down terminal emulator based on KDE Konsole techonology. It is distributed under the terms of the GNU GPL Version 2. It includes features such as:
Smoothly rolls down from the top of your screen
Configurable dimensions and animation speed
Sophisticated D-Bus interface
To install Yakuake, use the following command:
$ sudo dnf install -y yakuake
Startup and configuration
If you’re runnign KDE, open the System Settings and go to Startup and Shutdown. Add yakuake to the list of programs under Autostart, like this:
It’s easy to configure Yakuake while running the app. To begin, launch the program at the command line:
$ yakuake &
The following welcome dialog appears. You can set a new keyboard shortcut if the standard one conflicts with another keystroke you already use:
Now click the menu button, and the following help menu appears. Next, select Configure Yakuake… to access the configuration options.
You can customize the options for appearance, such as opacity; behavior, such as focusing terminals when the mouse pointer is moved over them; and window, such as size and animation. In the window options you’ll find one of the most useful options is you use two or more monitors: Open on screen: At mouse location.
The main shortcuts are:
F12 = Open/Retract Yakuake
Ctrl+F11 = Full Screen Mode
Ctrl+) = Split Top/Bottom
Ctrl+( = Split Left/Right
Ctrl+Shift+T = New Session
Shift+Right = Next Session
Shift+Left = Previous Session
Ctrl+Alt+S = Rename Session
Below is an example of Yakuake being used to split the session like a terminal multiplexer. Using this feature, you can run several shells in one session.
Tilda is a drop-down terminal that compares with other popular terminal emulators such as GNOME Terminal, KDE’s Konsole, xterm, and many others.
It features a highly configurable interface. You can even change options such as the terminal size and animation speed. Tilda also lets you enable hotkeys you can bind to commands and operations.
To install Tilda, run this command:
$ sudo dnf install -y tilda
Startup and configuration
Most users prefer to have a drop-down terminal available behind the scenes when they login. To set this option, first go to the app launcher in your desktop, search for Tilda, and open it.
Next, open up the Tilda Config window. Select Start Tilda hidden, which means it will not display a terminal immediately when started.
Next, you’ll set your desktop to start Tilda automatically. If you’re using KDE, go to System Settings > Startup and Shutdown > Autostart and use Add a Program.
If you’re using GNOME, you can run this command in a terminal:
When you run for the first time, a wizard shows up to set your preferences. If you need to change something, right click and go to Preferences in the menu.
You can also create multiple configuration files, and bind other keys to open new terminals at different places on the screen. To do that, run this command:
$ tilda -C
Every time you use the above command, Tilda creates a new config file located in the ~/.config/tilda/ folder called config_0, config_1, and so on. You can then map a key combination to open a new Tilda terminal with a specific set of options.
The main shortcuts are:
F1 = Pull Down Terminal Tilda (Note: If you have more than one config file, the shortcuts are the same, with a diferent open/retract shortcut like F1, F2, F3, and so on)
F11 = Full Screen Mode
F12 = Toggle Transparency
Ctrl+Shift+T = Add Tab
Ctrl+Page Up = Go to Next Tab
Ctrl+Page Down = Go to Previous Tab
The Drop-down Terminal GNOME Extension lets you use this useful tool in your GNOME Shell. It is easy to install and configure, and gives you fast access to a terminal session.
Fedora Silverblue is becoming more and more popular inside and outside the Fedora world. So based on feedback from the community, here are answers to some interesting questions about the project. If you do have any other Silverblue related questions, please leave it in the comments section and we will try to answer them in a future article.
What is Silverblue?
Silverblue is a codename for the new generation of the desktop operating system, previously known as Atomic Workstation. The operating system is delivered in images that are created by utilizing the rpm-ostree project. The main benefits of the system are speed, security, atomic updates and immutability.
What does “Silverblue” actually mean?
“Team Silverblue” or “Silverblue” in short doesn’t have any hidden meaning. It was chosen after roughly two months when the project, previously known as Atomic Workstation was rebranded. There were over 150 words or word combinations reviewed in the process. In the end Silverblue was chosen because it had an available domain as well as the social network accounts. One could think of it as a new take on Fedora’s blue branding, and could be used in phrases like “Go, Team Silverblue!” or “Want to join the team and improve Silverblue?”.
What is ostree?
OSTree or libostree is a project that combines a “git-like” model for committing and downloading bootable filesystem trees, together with a layer to deploy them and manage the bootloader configuration. OSTree is used by rpm-ostree, a hybrid package/image based system that Silverblue uses. It atomically replicates a base OS and allows the user to “layer” the traditional RPM on top of the base OS if needed.
Why use Silverblue?
Because it allows you to concentrate on your work and not on the operating system you’re running. It’s more robust as the updates of the system are atomic. The only thing you need to do is to restart into the new image. Also, if there’s anything wrong with the currently booted image, you can easily reboot/rollback to the previous working one, if available. If it isn’t, you can download and boot any other image that was generated in the past, using the ostree command.
Another advantage is the possibility of an easy switch between branches (or, in an old context, Fedora releases). You can easily try the Rawhide or updates-testing branch and then return back to the one that contains the current stable release. Also, you should consider Silverblue if you want to try something new and unusual.
What are the benefits of an immutable OS?
One of the main benefits is security. The base operating system is mounted as read-only, and thus cannot be modified by malicious software. The only way to alter the system is through the rpm-ostree utility.
Another benefit is robustness. It’s nearly impossible for a regular user to get the OS to the state when it doesn’t boot or doesn’t work properly after accidentally or unintentionally removing some system library. Try to think about these kind of experiences from your past, and imagine how Silverblue could help you there.
How does one manage applications and packages in Silverblue?
For graphical user interface applications, Flatpak is recommended, if the application is available as a flatpak. Users can choose between Flatpaks from either Fedora and built from Fedora packages and in Fedora-owned infrastructure, or Flathub that currently has a wider offering. Users can install them easily through GNOME Software, which already supports Fedora Silverblue.
One of the first things users find out is there is no dnf preinstalled in the OS. The main reason is that it wouldn’t work on Silverblue — and part of its functionality was replaced by the rpm-ostree command. Users can overlay the traditional packages by using the rpm-ostree install PACKAGE. But it should only be used when there is no other way. This is because when the new system images are pulled from the repository, the system image must be rebuilt every time it is altered to accommodate the layered packages, or packages that were removed from the base OS or replaced with a different version.
Fedora Silverblue comes with the default set of GUI applications that are part of the base OS. The team is working on porting them to Flatpaks so they can be distributed that way. As a benefit, the base OS will become smaller and easier to maintain and test, and users can modify their default installation more easily. If you want to look at how it’s done or help, take a look at the official documentation.
What is Toolbox?
Toolbox is a project to make containers easily consumable for regular users. It does that by using podman’s rootless containers. Toolbox lets you easily and quickly create a container with a regular Fedora installation that you can play with or develop on, separated from your OS.
Is there any Silverblue roadmap?
Formally there isn’t any, as we’re focusing on problems we discover during our testing and from community feedback. We’re currently using Fedora’s Taiga to do our planning.
What’s the release life cycle of the Silverblue?
It’s the same as regular Fedora Workstation. A new release comes every 6 months and is supported for 13 months. The team plans to release updates for the OS bi-weekly (or longer) instead of daily as they currently do. That way the updates can be more thoroughly tested by QA and community volunteers before they are sent to the rest of the users.
What is the future of the immutable OS?
From our point of view the future of the desktop involves the immutable OS. It’s safest for the user, and Android, ChromeOS, and the last macOS Catalina all use this method under the hood. For the Linux desktop there are still problems with some third party software that expects to write to the OS. HP printer drivers are a good example.
Another issue is how parts of the system are distributed and installed. Fonts are a good example. Currently in Fedora they’re distributed in RPM packages. If you want to use them, you have to overlay them and then restart to the newly created image that contains them.
What is the future of standard Workstation?
There is a possibility that the Silverblue will replace the regular Workstation. But there’s still a long way to go for Silverblue to provide the same functionality and user experience as the Workstation. In the meantime both desktop offerings will be delivered at the same time.
How does Atomic Workstation or Fedora CoreOS relate to any of this?
Atomic Workstation was the name of the project before it was renamed to Fedora Silverblue.
Fedora CoreOS is a different, but similar project. It shares some fundamental technologies with Silverblue, such as rpm-ostree, toolbox and others. Nevertheless, CoreOS is a more minimal, container-focused and automatically updating OS.
Productivity apps are especially popular on mobile devices. But when you sit down to do work, you’re often at a laptop or desktop computer. Let’s say you use a Fedora system for your platform. Can you find apps that help you get your work done? Of course! Read on for tips on apps to help you focus on your goals.
All these apps are available for free on your Fedora system. And they also respect your freedom. (Many also let you use existing services where you may have an account.)
FocusWriter is simply a full screen word processor. The app makes you more productive because it covers everything else on your screen. When you use FocusWriter, you have nothing between you and your text. With this app at work, you can focus on your thoughts with fewer distractions.
FocusWriter lets you adjust fonts, colors, and theme to best suit your preferences. It also remembers your last document and location. This feature lets you jump right back into focusing on writing without delay.
To install FocusWriter, use the Software app in your Fedora Workstation. Or run this command in a terminal using sudo:
sudo dnf install focuswriter
This unique app is designed, as you can guess, for the GNOME desktop environment. It’s a great fit for your Fedora Workstation for that reason. ToDo has a simple purpose: it lets you make lists of things you need to get done.
Using ToDo, you can prioritize and schedule deadlines for all your tasks. You can also build as many tasks lists as you want. ToDo has numerous extensions for useful functions to boost your productivity. These include GNOME Shell notifications, and list management with a todo.txt file. ToDo can even interface with a Todoist or Google account if you use one. It synchronizes tasks so you can share across your devices.
To install, search for ToDo in Software, or at the command line run:
sudo dnf install gnome-todo
If you are a KDE using productivity fan, you may enjoy Zanshin. This organizer helps you plan your actions across multiple projects. It has a full featured interface, and lets you browse across your various tasks to see what’s most important to do next.
Zanshin is extremely keyboard friendly, so you can be efficient during hacking sessions. It also integrates across numerous KDE applications as well as the Plasma Desktop. You can use it inline with KMail, KOrganizer, and KRunner.
