This tutorial is on how to zoom the screen in Ubuntu using GNOME or KDE Magnify feature. Windows users may be aware of the Magnifier inbuilt application, where in a user can simply select a Zoom Level(%) and magnify his screen. Since Linux is no inferior to Windows, there is a similar feature for zooming screen in Linux.
Magnify Screen using Shortcut
The shortcut for magnifying the Screen is
Zoom Up – Windows Key + Scroll Up
Zoom Down – Windows Key + Scroll Down
The Level of Zoom depends on the amount of the scroll. To my amazement the tool can zoom to a much greater level than expected.
