I am using Fedora 20 with the Mate desktop. I sometimes give talks, using LibreOffice Impress for a slide show, with a laser to point out details on the screen. I will be giving a talk where the slides are displayed on a TV screen, which is non-reflective so the little red spot does not show. The mouse pointer is an obvious substitute, but the arrow icon does not show up very well. Is there a way of using a different, more visible icon, say one that I can choose from a set provided, or that I can design for myself?
I see my question has been edited, but I'm not sure it was needed or that it is now an improvement on what I wrote originally. Especially the comma after "more visible", that has changed the sense of it, and I particularly do not like to see the "Please" deleted, I like to be polite.
I have followed switch87 suggestions and downloaded a new theme, which is now installed thanks to his help. I very much appreciate his patient help.
