Greetings, jacksbutler.

In my case /etc/alternatives/xcursor-theme points to /etc/X11/cursors/core.theme. My /etc/X11/cursors/ has three other choices.

I could, in principle, change the /etc/X11/cursors/'link' to one of the others.
I haven't tried it, but you can, by deleting the current 'link' and doing an ln -s
operation to select one of the other styles.

Let us know how you make out.
