I just uncomment =E2=80=98Option "NoDRI"=E2=80=99 in xorg.conf=E2=80=99s De=
vice section and
re-login; this makes Compiz not start until I comment that line out
again. (I have my Compiz customised, and switching the Visual Effects
back would reset the configuration.)

Here=E2=80=99s mine. It=E2=80=99s a hodgepodge of stuff (mostly from ThinkW=
iki), and
some of the lines throw errors, but it does seem to lower PowerTop=E2=80=99s
stats significantly:
