I'm having trouble loading my NVIDIA drivers on different kernels. I think I narrowed it down towards my driver installation. I have the newest 450 driver installed, but there are remnants of the old 440 driver, I can't figure out how to uninstall them and reinstall my 450 drivers.

dpkg -l | grep nvidia

The problem seems to be "rc libnvidia-compute-440:amd64 440.100-0ubuntu0.20.04.1 amd64 NVIDIA libcompute package"

Anyone have any suggestions? Thank you.

  • The libnvidia-compute-440 is not installed. Instead of asking this I suggest to describe what is your real problem "with different kernels:" See XY Problem

Nevermind, I figured it out myself. (thanks pilot6)

sudo apt-get remove --purge '^nvidia-.*'

sudo apt-get --purge remove libnvidia-compute-440

Then reinstalled the NVIDIA driver. Now my driver works on the different versions of kernels I have installed. Hopefully this helps someone else in the future.
