I have "headless" machine with video card, I use very rarely, only if I want physical access to it. The cooler of this video card became old and started to produce bad noise.

Can I disable this video card in such a way, that it:

  1. will turn on again on reboot

  2. a cooler stop to rotate

I did:

lspci | grep VGA
sudo lspci -vs 01:00

To know it's module then I put:

blacklist radeon

into:

/etc/modprobe/blacklist.conf

But, this didn't work.

How to accomplish this?

First, look for Bus ID of the graphic card. A possible method is lspci | grep VGA. An output example is:

XX:XX.X VGA compatible controller: NVIDIA Corporation Device 1b80 (rev a1)

Now, you can disable temporally this GPU assigning the value 1 in a file called “remove” inside the correct path of this PCI device. Changing XX with previous Bus ID values.

sudo echo 1 > /sys/bus/pci/devices/0000:XX:XX.X/remove

This command will disable the GPU in runtime. A restart will put the GPU available again. I tested it with a Nvidia GPU in a CentOS 7 server. Maybe the path is different for other GPUs or GNU/Linux distributions. I hope this configuration disables the cooler too.
