DIsable my nv video card driver in linux
- by Dahaka Wang
I'm trying to passthrough my nv video card to my domU, but I could not bind my video card to the pciback driver
I only have one video card with the pci number 0000:03:00.0, so I used the following command
echo -n "0000:03:00.0" > /sys/bus/pci/drivers/nouveau/bind
to unbind the nouveau driver from my video card.
The screen went black because I have forcefully removed the video driver, therefore I ssh'd into the computer to run further commands
I ran:
echo -n "0000:03:00.0" > /sys/bus/pci/drivers/pciback/bind
to try to bind it to my pciback driver, but I got:
bash: echo: write error: No such device
I found out that this was the message shown when trying to bind a PCI device which is already bound. Therefore, I think that something was still using my video card
Can anyone help me out? Thanks a lot!
