[Bug 283100] Re: powertop shows kwin generating lots of wakeups (intrepid, kde4)

[Martin Gräßlin]

The problem of too many wakeups is solved in KDE 4.2 being released this
month. KWin will be idle and don't wake up if nothing has to be painted.
I just did the test and KWin is at about 8 wakeups per second when being
idle.

Nevertheless my nvidia binary blob is still responsible for 60 wakeups
per second when compositing is enabled. I have no idea if this can be
improved (I guess no) and I don't know if this is the same for other
drivers.

Please note that the fps effect will destroy performance tests as kwin
can't idle if fps effect is activated.
