Compiz, or Kwin effects.

File bugs! Perform tests with powertop and report your experience. You
might want to check out the Phonorix forums for some help, there are
some real gurus there and power economy seems to be on-topic there.

No, perform your own tests on your own equipment.

If the distros are running on the hardware (not virtualized) then it
could be interesting. But the only real useful information would be a
definitive statement such as "XYZ application draws excessive power
under ABC conditions". Powertop will help you figure that out.

I do not know why they chose the word Composting. In Hebrew we call it
"spun" in the sense of thread being created from cotton. I'm sure that
there is a technical reason for the name, try wikipedia. In any case,
to disable it you would disable the Compiz or Kwin effects.

Thanks! CC me.

No, I mean this gem:
