Thanks Francis. He will be using 17.10 with Gnome UI and then moving
onto the LTS in the spring, then he should be ok with that for some
time. So Unity Tweak is not available. Gnome Tweak Took has a choice
of cursors, but not a particularly large one. With the screen
magnifier he seems to be ok with the regular cursor, and the hairline
cursor is very good.
