True, but is it worth the hassle? You have to have a good reason for doing
it and know what you are doing. It is one quick way for newbs to mess up
their system.

As for monitor settings, I am not sure where it come from. Mine is a much
modified installation. One of the perils of installing every possible
desktop environment. I think that it may have come with XFCE so ignore what
I wrote about it. Sorry for confusing things needlessly.
