Does Windows Magnifier run on Linux?

Magnifier is a Windows feature rather than a program you installed, so there is nothing to bring across. On Windows you open it with the Windows key and the plus sign, or from Settings under Accessibility, and it enlarges all or part of the screen in a full screen, docked or lens view.

Linux has the same feature and it is already there. On GNOME you find it in Settings under Accessibility and Zoom, and the accessibility icon in the top bar turns it on and off afterwards. The options line up closely with what you are used to: how much it magnifies, whether the view follows the mouse, where the magnified area sits, crosshairs to help you find the pointer, and colour filters including inverted colours and brightness and contrast adjustment.

One difference is worth naming. Windows 10's Magnifier can read text aloud. The Linux desktop magnifier magnifies only, so if you use that reading feature you need Orca running alongside, and the two are set up in separate places rather than being one tool.

The other difference is that this moves with the desktop you choose. Cinnamon and KDE both have zoom, and the controls and the feel of it differ. If magnification is how you read the screen, that alone is a good reason to try more than one desktop from a live USB session before deciding.
