Force Nvidia Powermizer to always set performance mode - Ubuntu 11.10 (Update)

This is an update from an older post, as that particular method no longer seems to work in the latest version of Ubuntu. This one, however, does.

Open xorg.conf with your favourite editor:

sudo nano /etc/X11/xorg.conf
Add the following line under the section "Device"
Option "RegistryDwords" "PerfLevelSrc=0x2222"
So that your device section looks something like this:
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "NoLogo" "True"
Option "RegistryDwords" "PerfLevelSrc=0x2222"
Save and reboot, hopefully your performance level is now always at maximum.


  1. Worked perfectly, thank-you! Bookmarked for the next re-install. :)

  2. Doesn't work on 12.04 with 304.

  3. Same deal on Fedora 18 with 304.64 driver on an Nvidia K1000M card -- switches between adaptive and performance mode, or stays in performance mode.

    nvidia-settings shows power source as battery even though plugged into AC, fun.
