How to Customise the Dock Position, Icon Size, and Auto-Hide in Ubuntu

The Ubuntu desktop features a prominent application launcher bar—known as the Ubuntu Dock—pinned to the left edge of the screen by default. While this left-hand vertical layout is iconic and makes efficient use of wide 16:9 monitor aspect ratios, many users migrating from Windows prefer a classic bottom taskbar, while macOS users prefer a floating bottom dock. Ubuntu GNOME includes native customisation toggles that allow you to reposition the dock, adjust icon scaling, and enable intelligent auto-hiding without installing third-party extension tools.

Why Customise Your Ubuntu Dock?

Tailoring dock geometry improves desktop ergonomics:

• Maximise Screen Real Estate: Enabling auto-hide lets full-screen browser windows and coding editors stretch completely across your monitor.
• Familiar Bottom Layout: Relocating the dock to the bottom creates an intuitive, comfortable experience for users transitioning from Windows.
• Compact Icon Scaling: Shrinking the icon size prevents long lists of pinned applications from overflowing into scrollable arrows on smaller laptop screens.

How to Change Dock Position (Bottom, Left, Right)

Adjusting the dock placement takes two clicks in Ubuntu Settings:

1. Open the Settings app from the application grid (or click the top-right status cluster and select the Settings gear).
2. Click on Ubuntu Desktop in the left sidebar.
3. Locate the Dock section.
4. Find the setting labelled Position on screen.
5. Click the dropdown menu and select Bottom, Left, or Right. The dock will immediately move to your chosen screen edge.

How to Resize Application Icons

If the application icons feel too large or consume too much vertical space:

1. Under the same Dock settings section, locate the Icon size slider.
2. The default size is typically set to 48 pixels.
3. Drag the slider to the left to shrink icons down to 32 or 36 pixels for a sleek, compact appearance.
4. Drag to the right if you are using a 4K display and need larger touch targets.

How to Enable Auto-Hide and Disable Panel Mode

To give the Ubuntu dock a floating, modern aesthetic:

• Enable Auto-Hide: Toggle on Auto-hide the Dock. The dock will smoothly slide out of sight whenever any application window overlaps its area, reappearing only when you move your cursor to that screen border.
• Disable Panel Mode: Turn off the toggle for Panel mode. Instead of stretching edge-to-edge across the entire screen border, the dock will shrink into a neat, floating dock centred on your display (similar to macOS).
