In the readme of the latest nvidia drivers theres an option you can set so that the nvidia driver doesnt interrupt the cpu 60 times a sec. I'v added the option OnDemandVBlankInterrupts to my xorg.conf.

Code:
Section "Device"
        Identifier      "Nvidia"
        Driver          "nvidia"
        Card            "** NVIDIA (generic)                   [nv]"
        Option          "OnDemandVBlankInterrupts"      "1"
EndSection


It doesnt seem to work, powertop still gives 60 interrupts. When I check the xorg log I get this.
Code:
(WW) NVIDIA(0): Option "OnDemandVBlankInterrupts" is not used


Its a laptop gpu 8600M/GT.

Any ideas ?

Using the driver from the nvidia website seems to fix the problem. Any ideas why ? Does the gentoo package use a speciaal var for compiling the driver ?

Currently I'm using the latest driver from the nvidia site
100.14.19
emerge nvidia-drivers gives version
100.14.09

Ah there's the problem :)

So for people who have the same problem, wait until the package has been updated.

equery list -p -o -e nvidia-drivers
