I am using nvidia 180.11 on a MacBook Air 2,1 running ubuntu amd64. Everything is working fine, including the 2560x1600 external Dell screen. I am now trying to get the temperature down as I am not really using any 3D applications. I was trying with all kind of options for PowerMizer, but always get
$ nvidia-settings -q GPUCurrentPerfLevel -t
which naturally transforms into heat and noise. What I tried so far:
Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3; PowerMizerLevel=0x3; PowerMizerLevelAC=0x3;"
And all kinds of combinations of it, but the GPUCurrentPerfLevel always stayed on 2. If someone has it working on a 9400m powered notebook with this or an older driver, or knows that the most recent one does not work anyway, I would not have to go through the manual download / compile mess...
