I am seeing this issue specifically on the Hybrid GPU (11G-P4-6598) but not on the EVGA GeForce GTX 1080 Ti SC2 and EVGA GeForce GTX 1080 Ti SC (non Hybrid) and on “newer” 4xx.xx versions of nvidia-settings. Specifics:
m1@Miner2:~ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.1 LTS Release: 18.04 Codename: bionic m1@Miner2:~ nvidia-settings --version
nvidia-settings: version 418.56
m1@Miner2:~ nvidia-settings --terse --query [fan:1]/GPUTargetFanSpeed 50 m1@Miner2:~ nvidia-settings --terse --query [fan:1]/GPUCurrentFanSpeedRPM
The fans are spinning and, IIRC, this worked in previous versions. I have tried upgrading to 418.67 and the problem remains. IIRC, this worked in 396.
I can provide additional details as necessary.
