 |
|
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. |
