** Description changed: Hello, I am a laptop user with 5900HX and RTX3080 Mobile. Today I noticed that psensor keeps my dGPU awake. When I close psensor I become able to see "D3Cold" in the power state of the GPU. Similar to this "nvidia-smi" - command wakes up the dGPU. It took a lot of time to find the root of the - problem. I think dGPU temperature measuring shouldn't wake the device or - keep it awake. + command wakes up the dGPU. To repeat the problem: - Install psensor. Set up start on boot. - Select "On-Demand" from Nvidia Settings. (So dGPU should be enabled when requested) - Restart. - - Run "cat /sys/bus/pci/devices/0000:01:00.0/power", output shows "D0" instead of "D3Cold" + - Run "cat /sys/bus/pci/devices/0000:01:00.0/power_state", output shows "D0" instead of "D3Cold" Description: Ubuntu 20.04.3 LTS Release: 20.04 psensor: Installed: 1.1.5-1.1ubuntu1 Candidate: 1.1.5-1.1ubuntu1 Version table: *** 1.1.5-1.1ubuntu1 500 500 http://archive.ubuntu.com/ubuntu focal/universe amd64 Packages 100 /var/lib/dpkg/status nvidia-smi output: +-----------------------------------------------------------------------------+ | NVIDIA-SMI 470.63.01 Driver Version: 470.63.01 CUDA Version: 11.4 | |-------------------------------+----------------------+----------------------+ | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.
