Created attachment 135851 [details] xorg log file Our CUDA-powered scientific workstation uses 3 GPU (GeForce GTX TITAN X (GM200-A)). OS is Ubuntu 17.10. NVidia driver version is 384.90. We want to use "Coolbits" option of proprietary driver to allow manual control of fan speed. But seems that xorg sends this option only to Device0. $ cat /etc/X11/xorg.conf.d/10-gpu.conf Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" Option "Coolbits" "4" BusID "PCI:1:0:0" EndSection Section "Device" Identifier "Device1" Driver "nvidia" VendorName "NVIDIA Corporation" Option "Coolbits" "4" BusID "PCI:2:0:0" EndSection Section "Device" Identifier "Device2" Driver "nvidia" VendorName "NVIDIA Corporation" Option "Coolbits" "4" BusID "PCI:3:0:0" EndSection $ cat /etc/X11/xorg.conf.d/20-screen.conf Section "Screen" Identifier "Screen0" Device "Device0" GPUDevice "Device1" GPUDevice "Device2" Monitor "Monitor0" DefaultDepth 24 Option "Coolbits" "4" SubSection "Display" Depth 24 EndSubSection EndSection $ grep -i coolbits /var/log/Xorg.0.log [ 10.187] (**) NVIDIA(0): Option "Coolbits" "4" Full xorg log attached.
