Worked in ubuntu 18, allowing me to manually control fan speed during training using the “NVIDIA X Server Settings” app. My 2 titan rtx run 86C during training. If I manually set the fan to 100%, temp 76C.
Upgraded to ubuntu 20.04, everything very stable except after setting the
coolbits=4. When I do, I get manual fan control, but after the screen times out and darkens, I log in, the mouse does not appear. reboot using the
T to get a terminal(no mouse),
sudo reboot, log in and all is fine until the screen darkens after a timeout.
Delete the /etc/X11/xorg.config, reboot, then all is good again, even after screen times out and darkens, but no GPU fan speed control.
Any other way to enable manual fan speed control on NVIDIA?
I tried sudo
nvidia-smi --gpu-target-temp=70 but this had no effect on fan speed.
