This simple tutorial shows how to remove the trash icon from the dock in Ubuntu 21.10 Impish Indri.

Different to the previous releases, Ubuntu 21.10 puts the trash icon on left dock instead of the desktop. However, I don’t use the trash icon in either location. Instead, I removes files using right-click menu options, and go to trash via file manager left sidebar.

If you also find it useless, then here’s how to remove it either via a single command or by a graphical configuration tool.

Single command to remove Trash from the dock:

Press Ctrl+Alt+T key combination on keyboard to open terminal. When it opens, run the command below will tell Ubuntu Dock to hide the trash icon:

gsettings set show-trash false

(Optional) The command takes effect immediately. If you change your mind and want to revert it back. Use command:

gsettings reset show-trash

Hide Trash from Ubuntu Dock via Dconf Editor:

For beginners and/or those hate Linux commands, an advanced graphical configuration tool “Dconf Editor” is present to do the job.

First, search for install “Dconf Editor” from Ubuntu Software if you don’t have it:

Next, search for and launch the tool from activities overview screen. When it opens, click on “I’ll be careful” button, and then navigate to “org/gnome/shell/extensions/dash-to-dock“.

There you’ll see all the settings for Ubuntu Dock. Scroll down and toggle off the slider icon for “show-trash” will do the trick.

That’s it. Enjoy!

After installed the new Ubuntu 21.10, one of the top things to do is tweaking the left dock panel.

Via “System Settings -> Appearance”, you may change the panel position to bottom, adjust icon size, and enable auto-hide. However, the 9 dots ‘Show Applications’ icon sticks to the bottom which is not movable.

Move ‘Show Applications’ button to the Top:

Though you can not drag moving the icon, Ubuntu has hidden option to change the position. And you may run single command in terminal to do the trick.

Press Ctrl+Alt+T on keyboard to open terminal. When it opens, paste the command below and hit Enter:

gsettings set show-apps-at-top true

The icon goes to top (or left if you moved dock to bottom) immediately after running the command. So it will look like:

Shorten the Dock Panel:

The dock launcher is easy to move to the bottom, but Appearance setting does not has option to make it compact, so to have Mac OS style short bottom panel.

To shorten Ubuntu Dock, press Ctrl+Alt+T to open terminal and run command:

gsettings set extend-height false

After that, it will look like:

Configure Ubuntu Dock via Dconf Editor:

For those hate Linux commands, there’s an advanced configuration tool ‘Dconf Editor’ available to do the trick.

Search for and install the tool from Ubuntu Software if you don’t have it.

Next, open Dconf Editor by searching from activities overview screen. Then navigate to “org/gnome/shell/extensions/dash-to-dock“. There you’ll see a list of options to configure the dock panel, including moving ‘Show Applications’, ‘extend-height’, ‘click to minimize’, and more.

That’s all. Enjoy!

For laptop and desktop PC with more than one audio input and output devices, it’s possible to switch between audio devices quickly with upper right corner system tray menu.

It’s a common situation that users have more than one audio devices connected to the computer. GNOME, the default Ubuntu Desktop Environment, provides Sound settings to choose which input and/or output device to use.

To make life easier, a Gnome extension is available to integrate the settings into system tray status menu under volume control slider. So users can quickly choose a speaker, HMDI, microphone or other input device via few clicks.

The extension offers a setting dialog allows to select which device, e.g., HDMI , Speakers, microphone etc, you would like to display or hide in menu. It’s possible to hide the menu when there’s only one choice, or manually toggle visible of either menu, as well as audio profiles.

Install the audio device chooser extension:

The extension supports up to GNOME 40, it works on Ubuntu 18.04, Ubuntu 20.04, Ubuntu 21.04, and next Ubuntu 21.10. As well, all recent GNOME based Linux distros, e.g., Debian 11, Fedora 34, CentOS 8, and Manjaro are supported.

1.) Firstly, open terminal by either searching from activities overview or pressing Ctrl+Alt+T on keyboard.

2.) When terminal opens, run command to install the chrome-gnome-shell package which allows to install Gnome extensions using your web browser. Also install gnome-shell-extension-prefs (Gnome Extensions app) package, the tool to manage all installed extensions.

sudo apt install chrome-gnome-shell gnome-shell-extension-prefs

3.) Finally, go to the link button below and turn on the slider icon to install the extension.

Don’t worry if you don’t see the toggle icon, install the browser extension via ‘Click here to install the browser extension’ link and refresh the web page will make it visible.

After installation, search for and open “Gnome Extensions” from the overview screen. Then click on the gear button for this extension to configure the audio device chooser menu.

That’s all. Enjoy!

After half a year of development, the GNOME project announced version 41 of its popular Linux desktop environment.

GNOME 41 comes with some exciting new features. The upper right corner system tray menu now includes option to make it easy to switch Power Mode between “Balanced” and “Power Saver”. It’s said that “Performance mode” is only visible on hardware that supports this feature, though I don’t understand which hardware required, may be a dedicated graphics card.

The GNOME Settings panel introduced two new items in the left pane: Multitasking and Mobile Network.

The “Multitasking” pane offers options to toggle top-left hot-corner to open Activities overview, app window auto-resizing function when dragging against screen edges; set dynamic or fixed number of workspaces; show workspace on primary only or all displays; super + tab switching for apps on all workspaces or current workspace only.

The “Mobile Network” pane is only visible when a supported modem is present, e.g., 2G, 3G, 4G, and GSM/LTE. It allows to set the network type, whether to use mobile data and data roaming. And it supports multiple SIMs and modems, allows to easy switching network modes.

Other changes in Gnome 41 include:

  • New “Connections” remote desktop app with VNC and RDP support.
  • Overhaul Gnome Software.
  • Redesigned Gnome Music.
  • Faster response to keyboard & pointer input on Wayland.
  • New default GL renderer for GTK4.
  • Create encrypted .zip archives in Files.
  • Import events to Calendar from .ics files.
  • Code cleanup in Mutter, and more.

How to Get Gnome 41:

Usually, the newest GNOME desktop will be first made into Fedora and Arch Linux. Users are recommended to wait your Linux distribution to include the desktop environment.

For testing and development purpose, you can try the GNOME OS either in virtual machine or real computer. Or download the iso image from the link button below:

For PC / notebook has a small display, it’s possible to hide the top panel in GNOME desktop to get more spaces and/or focus on your work.

There’s a ‘Hide Top Bar‘ extension that enables ability to auto-hide the top bar, just like the left dock does. However, in this tutorial I’m going to introduce another extension.

It’s a very light extension that the developer promoted it has no options and no bugs! It will ALWAYS hide the top-bar, except only in overview screen. Just like GNOME shows the dock only in overview without Ubuntu Dock (Dash-to-dock) extension.

The extension will also disable the top-left hot-corner, which is used to trigger the ‘Activities‘ overview. It’s designed for those who are accustomed to start overview screen using the Windows (or Super) key, or three-finger touchpad gestures in GNOME 40 (defaults in Ubuntu 21.10).

As the picture shows though the top-bar is hidden, users can still click on top-right corner to get the system tray & indicator menu, or click on top-center to view the clock menu when there’s NO maximized app window.

Install Hide Panel Extension:

The extension so far works on Gnome 3.36 ~ 41, which means Ubuntu 20.04, Ubuntu 21.04, Ubuntu 21.10, and other Linux, e.g., Debian 11 and Fedora 34 are supported.

1.) To install it, firstly open terminal by pressing Ctrl+Alt+T on keyboard. And run command to install the required chrome-gnome-shell package if you don’t have it.

sudo apt install chrome-gnome-shell

2.) Next, open the gnome extension web page in browser, and turn on the slider icon to install it.

If you don’t see the slider icon, install browser addon/extension by clicking ‘click here to install browser extension‘ link and then refresh the page.

After installation, it starts working in a few seconds in my case. If not, you may restart Gnome Shell or log out and back in.

Uninstall Hide Panel extension:

To toggle on/off or remove extensions, it’s recommended to use the ‘Gnome Extensions’ app, which can be installed either directly from Ubuntu Software, or by running command in terminal:

sudo apt install gnome-shell-extension-prefs

Launch the tool once you installed it, and click on the little triangle icon after the extension, there you’ll see the button to remove it.
