Hi there

I've been tired of Windows 10 for a while now and can't justify the cost of a Mac, so I'm giving Ubuntu 18 a go on my Dell Precision 5720 AIO. I've already installed Ubuntu, updated, good to go, seems to run fine, but have a couple questions. I'm not a command line pro by any means, but I can get around. Definitely resourceful.

1. I have 2 4K displays, 1 is part of the computer and the other is a secondary monitor. Is there fracitional scaling? I only see the ability to adjust scaling from 100% to 200% and 200% is too large. 150% or 175% would be great.

2. I've reviewed this article on creating desktop shortcuts, but is it possible to make shortcuts to the home folder, drives in the system, and the network on the desktop? If so, can you point me to a step by step on that?

3. Is there a way to make the cursor larger or invert the cursor color (windows has an inverted cursor scheme for this, makes it very handy to find your cursor)

Thanks for any help you have, really appreciate it.
