Until 440.36. this works properly. (as a matter of course, coolbit=28 is defined in my xorg.conf)
/usr/bin/nvidia-settings -a '[gpu:0]/GpuPowerMizerMode=1' -a '[gpu:0]/GPUGraphicsClockOffset[4]=100' -a '[gpu:0]/GPUMemoryTransferRateOffset[4]=400' -a '[gpu:0]/GPUFanControlState[4]=0'
However with 440.40, this doesn’t work properly. It returns this.
$ /usr/bin/nvidia-settings -a '[gpu:0]/GpuPowerMizerMode=1' -a '[gpu:0]/GPUGraphicsClockOffset[4]=100' -a '[gpu:0]/GPUMemoryTransferRateOffset[4]=400' -a '[gpu:0]/GPUFanControlState[4]=0'
Attribute 'GPUPowerMizerMode' (maverick:1[gpu:0]) assigned value 1.

However, these clock speeds can be changed nvidia-settings in GUI. So I guess nvidia-settings should have a problem…
Thanks in advance!
