Installing CUDA 10.2 and RTX NVidia drivers on Ubuntu 18.04 LTS

I wanted install the NVidia Geforce drivers and CUDA development environment on fresh Ubuntu 18.04 installation.  The target machine is an HP Z820 with a Geforce RTX 2060 super card.

This assumes you want to write C code when building applicatoins for GPUs The Numba Installation Instructions say you only need the GPU drivers if you all your GPU programming is going to be done in Python.

What didn't work

Enabling proprietary drivers on installation did not work out of the box.

The out of the box install left my login process broken. The screen would turn black and a cursor would appear and then would cycle back to the login screen. The problem was the display driver/windows system crashed and then restarted back at login.  I was able to fix it by uninstalling the driver or doing an upgrade.


NVIDIA drivers are not installed.  You should remove the drivers and reboot before proceeding if the drivers are loaded.  Instructions exist on the internet.

  • sudo apt-get --purge remove cuda
  • sudo apt-get --purge remove cuda-x.y
