I'm looking for a tool that allows to zoom in on the screen regardless of the application or program you're currently running. This tool should not only magnify the screen, but also the mouse pointer.
Background of the question is as follows: I have a visual impairment, but would like to use Linux, mainly for data security reasons. So far, I always got frustrated when I tried to use it. I failed due to the seemingly trivial problem, that any magnifier in Linux I know would only magnify a screen area, but not the mouse pointer. Even if I can do most things just using the terminal by now, it is still very annoying to do e.g. a simple internet search when you can't see your own mouse pointer.
Scaling up the pointer to the largest possible size and changing its colour to red was not sufficient for me, when I last tried it. This try is now around three years ago, when I started studying at university. I'm wondering if in the meantime someone developed something that makes Linux actually usable for me. I really like the idea of free software, but as long as it's not accessible, I'm stuck with Mac OS.
