Ubuntu 25.10, code-name Questing Quokka was released! Here are some top things to do, after installed the new Ubuntu desktop release, to make it ready to use.

1. Enable “New Documents” Context Menu option

It’s been many years, GNOME still does NOT have a graphical option out-of-box to create new documents in file manager. Though, it’s easy to enable this feature by putting a file into user’s Template folder.

To do so, launch Text Editor and create a new empty document. Then, press Ctrl+Shift+S to open save file dialog. Finally, choose save it to Home -> Templates with whatever file-name you want to display as ‘New Document’ sub-menu option.

2. Configure Printer

The default “Printer” page in Settings is OK for basic use.

If you have a printer physically connected to the Ubuntu computer, then you may open terminal (Ctrl+Alt+T) and run command to install the graphical CUPS configuration tool:

sudo apt install system-config-printer

Tips: run sudo apt update to refresh cache if it says “Unable to locate package”.

Then, search & launch Printers app to get more controls, such as share printer, remote admin, policies, and default print options.

3. Configure the Left Panel

The left panel, aka Ubuntu Dock, is handled by an extension forked from dash-to-dock.

By going to Settings -> Ubuntu Desktop -> Dock, you may configure the left panel/dock with basic options, such as its position, icon size, auto-hide, shorten panel, show on primary or all displays, hide trash and volumes.

For more, install extension manager either by running the command below in terminal (Ctrl+Alt+T) or by using App Center (filter by Debian package):

sudo apt install gnome-shell-extension-manager

Then you may launch extension manager, and open preferences dialog for the Ubuntu Dock extension, which includes many more configure options for the left panel/dock:

• Intelligent autohide, with dodge windows, animation duration, pressure threshold options.
• Center icons in panel mode.
• Show/hide, and move “Show Apps” (the Ubuntu Logo) icon.
• Keyboard shortcuts.
• Click action (e.g., click to minimize).
• Appearance, e.g., background color, and opacity.

4. Install back default apps

If you chose the “Default Selection” option while installing Ubuntu 25.10, then you’ll see that many default applications are NOT pre-installed!

To install them back, simply launch App Center, then search and install the apps below one by one (mostly filtered by Debian package).

Or, open terminal (Ctrl+Alt+T) and run commands below instead to install.

  sudo apt install libreoffice

5. Install Multimedia Codec

Due to legal reason, Ubuntu does not include some media codec for video/audio playback, Microsoft TTF fonts, and RAR archive supports.

To get them, press Ctrl+Alt+T to open up a terminal window, and run command:

sudo apt install ubuntu-restricted-extras

While downloading & installing the MS fonts, it will prompt to accept licence, use Tab key to highlight OK and hit Enter.

6. Enable Flatpak support

For choice, add --user flag for current user only. Then, use the command in a Flathub app page to install (click down arrow besides “Install” button).

NOTE: After enabled Flatpak support, you need a log out and back in to apply variable changes.

Since Ubuntu 22.04, user needs to press Ctrl+Alt+T to open terminal, and run command to install the required library for AppImage support:

sudo apt install libfuse2

8. Install Configuration Tools
