JamesAdams Posted July 24, 2020 Share Posted July 24, 2020 Hi, i have a server on Unraid and i use a gpu (GTX 1060) in a windows 10 VM but i would link turn off the gpu when is not used by my vm because the gpu consume 30W in idle... for now i found this : Quote sudo echo 1 > /sys/bus/pci/devices/0000:XX:XX.X/remove it's turn off the card but i don't have the possibility to turn on the card... Thanks for your help. Quote Link to comment
Frank1940 Posted July 24, 2020 Share Posted July 24, 2020 This would have to be a hardware feature of the card. Plus, I doubt if any GPU card manufacturer ever dreamed of a situation where someone might actually want to turn off a video card! There might be a sleep or hibernation function on the card but that again would be a function of the card firmware. You might want to check on the Manufacturer's website or their user forum.

civic95man Posted July 24, 2020 Share Posted July 24, 2020 sudo echo 1 > /sys/bus/pci/rescan This should force a complete bus scan and re-add the previously removed (disconnected) device. Shouldn't cause any issues with already attached devices. I'm not around a *nix box at the moment otherwise I would try this, but I wonder if this would work: sudo echo 1 > /sys/bus/pci/devices/0000:XX:XX.X/rescan I'm really curious if this will actually reduce your power consumption Quote Link to comment
