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
xorg.conf
and~/.nvidia-settings-rc
- adding
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"
to/etc/modprobe.d/nvidia.conf
- nothing happened - adding Option
"RegistryDwords"
"PowerMizerLevel=0x2"
"PowerMizerLevelAC=0x2"
toxorg.conf
under device section : gdm did not start up - had to deletexorg.conf
to recover - adding Option
"RegistryDwords"
"PowerMizerEnable=0x0"
toxorg.conf
: nothing happened
Any idea how I can do this?
P.S. Ubuntu 12.10
