Tito, I know nothing about compositing an image. I gather my
fluxbox window manager does not do it. I run no DE and so presume
it does not to it either.

I tried:

    $ gsettings set compositing-manager false

but my syntax is wrong and I don't know why. I'm told to "Set the
value of KEY to VALUE. I thought compositing-manager was the key
and false the value.
