So I like this MacOS feature where your cursor displays in large. I was hoping if anyone knew of such software that replicates this functionality for Linux. Considering MacOS and Linux are both Unix, and libraries are different, could X or Wayland help replicate this?
It depends on your desktop environment. For GNOME, you can try jiggle. For me, Jiggle is listed as incompatible, unfortunately.
The built-in accessibility setting for finding your mouse is the Windows-style “press left ctrl to highlight the mouse”. KDE has the same feature, though they’re working on including a macOS-like jiggle feature in the upcoming Plasma 6 release.
