I’ve been trying to turn off nvidia PowerMizer (that is set the performance level to 2 – max). I can do it with nvidia-settings, but it goes back to default after restart. Here’s what I have tried:
- nvidia-settings as root – saving settings to
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"to
/etc/modprobe.d/nvidia.conf– nothing happened
- adding Option
xorg.confunder device section : gdm did not start up – had to delete
- adding Option
xorg.conf: nothing happened
Any idea how I can do this?
P.S. Ubuntu 12.10
Here is Solutions:
We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.
You need to remove whatever you’ve added to xorg.conf, and add something like the following:
Section "Device" Identifier "NVIDIA GeForce" Driver "nvidia" Option "RegistryDwords" "PerfLevelSrc=0x3322; PowerMizerDefaultAC=0x1" EndSection
PerfLevelSrc=0x3322 means it’s going to use fixed PowerMizer mode when on AC.
PowerMizerDefaultAC=0x1 defines the power mode, with
0x1 being Maximum performance.
There is no need to reboot, just logout/login.
There is an unofficial patch for recent versions of the proprietary NVIDIA graphics driver (334.21 and 337.12) that writes GPU target attributes like GPUPowerMizerMode to the configuration file of nvidia-settings. That means you can use the NVIDIA X Server Settings GUI to permanently set your desired performance level just as it should be.
Note: Use and implement solution 1 because this method fully tested our system.
Thank you 🙂
