Some of the xscreensaver hacks seem to be looking for font(s) that aren't
present on this machine:
memscroller: unable to load font: "-*-courier-bold-r-*-*-*-320-*-*-m-*-*-*"
memscroller: unable to load font: "-*-courier-bold-r-*-*-*-480-*-*-m-*-*-*"
memscroller: unable to load font: "-*-courier-bold-r-*-*-*-960-*-*-m-*-*-*"
memscroller: unable to load font: "-*-courier-bold-r-*-*-*-1440-*-*-m-*-*-*"
This is a new set-up-from-scratch F11 machine, not one that was upgraded from a
previous version.
What's missing?
