I expect it can be done from the command line but I don't quite
understand why you would want to do this.  Surely once set these
things stay the way you have set them 'for ever' until you change them
again.  The only reason I could see for doing it from the command line
would be because you want to do this every time you log-in/turn-on by
running a script, and this would be pointless.

I suppose you *might* want to install a script on lots of identical
machines to do this automatically so that all the machines act the
same way but this seems a bit unlikely! :-)

If your settings are not 'sticking' then there's something wrong that
needs fixing, a script to do this every time you turn on is a bodge.
