That is what I thought, so saying the solution is just to edit the
file is a bit of an oversimplification.  It is not just a matter of
editing a file, finding the line that says RefreshRate or similar and
changing the number.  It is a matter of understanding the syntax of
the file and knowing what to put in it in order to  set the refresh
rate.  Or is there a way of asking the system to generate a default
one matching the system so that one can just edit it?  Am I correct in
thinking that one can actually damage the hardware if one gets the
file horribly wrong?

I have not seen any explanation anywhere as to why the option to set
refresh rate has been removed from the gui.
