dmesg

NVRM: API mismatch: the client has the version 418.67, but
NVRM: this kernel module has the version 430.26.  Please
NVRM: make sure that this kernel module and all NVIDIA driver
NVRM: components have the same version.

Uninstall old driver 418.67 and install new driver 430.26 (download NVIDIA-Linux-x86_64-430.26.run):

sudo apt-get --purge remove "*nvidia*"
sudo /usr/bin/nvidia-uninstall
chmod +x NVIDIA-Linux-x86_64-430.26.run
sudo ./NVIDIA-Linux-x86_64-430.26.run

cat /proc/driver/nvidia/version

This also happened to me on Ubuntu 16.04 using the nvidia-348 package (latest nvidia version on Ubuntu 16.04).

However I could resolve the problem by installing nvidia-390 through the Proprietary GPU Drivers PPA.

So a solution to the described problem on Ubuntu 16.04 is doing this:

• sudo add-apt-repository ppa:graphics-drivers/ppa
• sudo apt-get update
• sudo apt-get install nvidia-390

Note: This guide assumes a clean Ubuntu install. If you have previous drivers installed a reboot migh be needed to reload all the kernel modules.

Answer 3

For completeness, I ran into this issue as well. In my case it turned out that because I had set Clang as my default compiler (using update-alternatives), nvidia-driver-440 failed to compile (check /var/crash/) even though apt didn't post any warnings. For me, the solution was to apt purge nvidia-*, set cc back to use gcc, reboot, and reinstall nvidia-driver-440.

Answer 4

I have to restart my kernels and remove all the packages that I have installed previously(during the first installation), please make sure to delete all the packages, even after removing packages by command below

sudo apt-get --purge remove "nvidia"

the packages like "libtinfo6:i386" doesn't get removed

I'm using Ubuntu 20.04 and Nvidia-driver-440 for that you have to remove all the packages shown below image

List of all the packages that need to be remove:

as shown in the image, make sure that the package you're installing is of the correct size that is 207 Mb for Nvidia-driver-440, if it's less it means you haven't removed all the packages.

Answer 5

I got the error failed to initialize NVML: Driver/Library version mismatch from my nvidia-gpu-temperature-indicator. And nvidia-smi failed to print any info. I tried to find if there were other versions of nvidia driver installed in my ubuntu. But I just found nvidia-driver-390. In the end, reboot helped me solve the problem.

Answer 6

I had reinstalled nvidia driver: run these commands in root mode:

1. systemctl isolate multi-user.target

2. modprobe -r nvidia-drm

3. Reinstall Nvidia driver: chmod +x NVIDIA-Linux-x86_64–410.57.run

4. systemctl start graphical.target

and finally check nvidia-smi
