The Sluggish Interface
The standard Ubuntu desktop environment (GNOME) uses an auto-hiding dock on the left side of the screen to save vertical space. When you move your mouse to the edge of the screen to summon the dock, there is a built-in animation delay—a slight hesitation before the dock slides out, followed by a smooth, deliberate sliding animation. While this looks elegant, power users often find this fraction-of-a-second delay incredibly sluggish, especially when trying to rapidly switch between applications or launch new tools during intense workflows.
Removing the Artificial Delay
To make the Ubuntu dock feel instantly responsive, you must modify hidden GNOME shell parameters using the Dconf Editor tool, allowing you to reduce both the initial hesitation delay and the animation speed to absolute zero.
First, open your terminal (Ctrl+Alt+T) and install the configuration tool by typing: sudo apt install dconf-editor and pressing Enter. Once installed, launch the “Dconf Editor” from your application grid (click “I’ll be careful” if a warning appears). Navigate through the folder tree by clicking: org > gnome > shell > extensions > dash-to-dock. Scroll down the long list of variables until you find require-pressure-to-show and turn the toggle switch to Off. Next, find show-delay, turn off “Use default value,” and change the custom value to 0. Finally, locate animation-time, turn off the default, and set the value to 0.0. Click the checkmark at the bottom to apply. Your dock will now instantly snap onto the screen the exact millisecond your cursor touches the edge, drastically improving the perceived speed of the operating system.
