Just Perfection, the popular tool to configure Gnome Shell behavior and UI elements, release new 35.0 version few days ago.

In case you don’t know about it, it’s an extension for GNOME desktop that provides a graphical interface to toggle visibility of the desktop elements, and change the common desktop behavior.

The extension provides pre-defined profiles to one click switch between default, minimal, and super minimal desktop appearance.

While, user may customize by hiding the top-panel, panel in overview, dash (dock), on-screen display (OSD), panel items (e.g., clock, indicators), menu items (e.g., calendar and events in clock menu), items in overview and more.

It as well can adjust the panel size (height), position, padding, clock position, OSD position, alt-tab preview size. And, it allows to disable or change animation speed, choose login to blank desktop or overview, maximize new window, disable Super (window logo) key, and more.

In the past few releases, it keeps adding new features, such as ability to hide quick settings buttons (e.g., Dark Mode, Night Light, Airplane), and use accent color for top panel icons though it requires GNOME 47+ and not work for Ubuntu.

The new Just Perfection version 35 added support for GNOME 49, which is default in Ubuntu 25.10 and Fedora 43, though they are all in development stage at the moment of writing.

And, it added ability to toggle visibility (show or hide) of window menu. It’s the menu that pops-up when you right-clicking on header of an app window, which contains options to take screenshot, set always on top, move, resize, or close window.

There are as well fixes for startup freeze in NixOS, and the page icon issue in preferences window for GNOME Shell 48.

How to Install Just Perfection:

The new Just Perfection releases supports GNOME from version 45 to 49. User may install it by visiting the EGO page via web browser:

Then use the ON/OFF toggle to install. Though you need to first install browser extension (if it asks) and refresh. And, Debian/Ubuntu needs to run command (Ctrl+Alt+T) to install the agent package first:

sudo apt install chrome-gnome-shell

For Ubuntu since 22.04, user may also install Extension Manager first from App Center (filter by Debian package), then use it to search & install Just Perfection.

Finally, use either GNOME Extensions or Extension Manager to open Just Perfection preferences page to tweak your desktop.

Like the new Ptyxis terminal emulator introduced in Ubuntu 25.10, here’s how to install and set it as default in current Ubuntu 24.04 and 22.04 LTS.

Ptyxis is a modern terminal emulator designed for GNOME with first-class container integration, such as auto-discovery and option to launch a container in new tab, preferences profiles with container integration for Podman, Toolbox, Distrobox, and JHBuild.

The terminal uses GTK4 + LibAdwaita for its modern user interface well integrated into GNOME. And, it supports configurable keyboard shortcuts, user-installable color palettes, GPU acceleration, integrated developer tool, and more.

Ubuntu 25.10 since snapshot 4 has added this terminal app as a replacement of GNOME Terminal. For current 2 Ubuntu LTS releases, it’s easy to install through Flatpak via the steps below.

1. Install Ptyxis

The latest Ptyxis (48.5 so far) won’t build in current Ubuntu 24.04 or 22.04 due to outdated GTK4 and libadwaita libraries. User may choose to install it as Flatpak package, which runs in sandbox environment.

NOTE: This step works only on X86_64 (modern Intel/AMD) and ARM64 platforms.

First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run the command below to install the flatpak daemon:

sudo apt install flatpak

You may run sudo apt update to refresh your system package cache, if the last command failed.

Then, install the terminal emulator by running command:

flatpak install https://dl.flathub.org/repo/appstream/app.devsuite.Ptyxis.flatpakref

This will install the app system wide, so all users can access it. For choice, you may add --user flag in command to install it for current user only.

Finally, either launch the terminal from menu (log out and back in if app icon not visible) or run flatpak run app.devsuite.Ptyxis to start from terminal.

And for future updates, run the command below to check & install:

flatpak update app.devsuite.Ptyxis

Step 2: Set Ptyxis as default terminal

If you would like to make your terminal apps use Ptyxis as default, and Ctrl+Alt+T launch this terminal instead of Gnome-Terminal, then run following commands one by one.

NOTE 1: Ptyxis has an option in its preferences dialog to set as default, though NOT work in my case.

NOTE 2: This step no longer works for Ubuntu 25.04 and later due to policy change.

Ubuntu until 25.04 uses /etc/alternatives/x-terminal-emulator symbolic link to determine the default terminal app. To configure it, use update-alternatives command to add alternatives and set which to use as default.

1. First, create a wrapper for Ptyxis executable by running command:

sudo nano /usr/bin/ptyxis.wrapper

This command will create a script ptyxis.wrapper under /usr/bin with nano command line text editor.

When it opens, paste the line below, so it will launch Ptyxis with --new-window flag.

#!/bin/sh
flatpak run app.devsuite.Ptyxis --new-window

Finally, press Ctrl+S to save and Ctrl+X to exit. And, run command below to add executable permission:

sudo chmod a+x /usr/bin/ptyxis.wrapper

You may skip creating the wrapper, and use /var/lib/flatpak/exports/bin/app.devsuite.Ptyxis in next commands. Which however only allows to open a single Ptyxis window when pressing Ctrl+Alt+T keyboard shortcut for multiple times.

2. Next, run command to install Ptyxis as an alternative:

sudo update-alternatives --install /usr/bin/x-terminal-emulator x-terminal-emulator /usr/bin/ptyxis.wrapper 10

Here you may replace /usr/bin/ptyxis.wrapper with one of the PATH to Ptyxis executable file below. As mentioned, it however allows only one Ptyxis window, unless passing --new-window flag.

• /var/lib/flatpak/exports/bin/app.devsuite.Ptyxis for default system-wide installation.
• $HOME/.local/share/flatpak/exports/bin/app.devsuite.Ptyxis if installed the terminal with --user flag.

Then, run the command below to choose default terminal:

sudo update-alternatives --configure x-terminal-emulator

In my case (see the screenshot), type 4 and hit Enter to select Ptyxis.

Step 3: Add “Open in Terminal” Context Menu option for Ptyxis

If you would like to add “Open in Terminal” look-like context menu to open selected folder in Ptyxis, the popular nautilus-open-any-terminal extension can do the job for Nautilus (aka GNOME Files).

1. First, run command in terminal to install dependency libraries:

sudo apt install python3-pip python3-nautilus gir1.2-gtk-4.0

2. Then, install the extension through pip:

python3 -m pip install --user nautilus-open-any-terminal --break-system-packages

The --break-system-packages flag is required in 24.04 due to PEP 668, though not for 22.04.

3. After installed the Nautilus extension, run the command below to generate dconf configuration:

glib-compile-schemas ~/.local/share/glib-2.0/schemas/

Then quit Nautilus to apply changes:

nautilus -q

4. Finally, launch Dconf Editor which can be installed from either Ubuntu Software or App Center (filter by Debian package).

Then, navigate to “com/github/stunkymonkey/nautilus-open-any-terminal”, and disable default values and set:

• flatpak to ‘system’ (or ‘user’ if you used --user flag when installing Ptyxis).
• terminal to ‘ptyxis’.

Finally, right-click on any folder or blank area in file manager to see the new option.

And, remove nautilus-extension-gnome-terminal package to get rid of the default ‘Open in Terminal’ option.
