Cuda: NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver

apt nvidia drivers package-management updates

19,556

Solution 1

Well I posted on the official NVIDIA boards, and shortly heard back that I just needed to remove a blacklist file (/lib/modprobe.d/blacklist-nvidia.conf) from my system and reboot.

Doing so got this straightened out :)

The steps are the following:

grep nvidia /etc/modprobe.d/* /lib/modprobe.d/*

Will return you entries of files that include a statement that includes "nvidia". Look for a statement that says blacklist nvidia

In the case of this author, the file was /lib/modprobe.d/blacklist-nvidia.conf Now remove this entire file, e.g. with:

sudo rm lib/modprobe.d/blacklist-nvidia.conf

Solution 2

Just in case some one is wasting time because of brilliant nvidia drivers, I've found on the net this gist:

and it worked.

I'm sorry to post a question that's been asked before, but I'm trying to configure cuda on an ubuntu 18.04 machine and am a little stuck.

I tried to install cuda 10.0 from a bash installer. I opted to install the driver too when running the install. Now, however, running nvidia-smi yields:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I attempted to completely uninstall all drivers with the following:

sudo apt-get --purge -y remove 'cuda*'
sudo apt-get --purge -y remove 'nvidia*'

I then tried to install a new driver with sudo apt install nvidia-driver-440, but I continue to get "NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver."

I'm now trying to figure out how to get my nvidia driver to work peacefully with my system and enable nvidia-smi. If that's not possible, I'd like to install a new driver. Any pointers on how to achieve either of these paths would be hugely helpful! I'm happy to provide any information along the way that might be useful...

Some clues: X seems to be disabled now (see below) but normally there's a console. Also `inxi -G1 is reporting that I'm still using the nouveau driver instead of nvidia.

The machine has two Titan RTX chips attached. Here's a screenshot of them in action yesterday before I borked the drivers:

I cross-posted this question on the official NVIDIA support forum: forums.developer.nvidia.com/t/…

Your nvidia 440 installed list looks normal (ignore the leftover 390), but your nvidia-smi screenshot shows the 435 driver. Did you change kernels too, to the 5.3 so the 440 would be offered?

Please explain what and how you do it. The post in the nvidia boards is not clear enough

I'm sorry you're having trouble with this @KansaiRobot. I was able to literally just run the three commands from the first response on the board: forums.developer.nvidia.com/t/… But there are many situations that can all cause this problem, so I would recommend posting to the boards with information on your particular situation. I bet someone over there can help...
