While there are Ubuntu packages available, we’ve found the most reliable option is to download the latest version of CUDA directly from NVIDIA’s developer website: With the drivers installed, the next step is to grab CUDA itself.

You’ll need to reboot your machine after installing the NVIDIA drivers, after which you can use the nvidia-smi command to check that the driver is installed and operating correctly. You can now use apt to install the latest version of the drivers, for example: apt install nvidia-390 Thankfully LXD 3.0 has a way to keep the two in sync without requiring installation of all the NVIDIA packages in both host and container. But CUDA still expects a local driver installation, and this means we need to have identical versions of both the drivers and CUDA on the host and any LXD containers we deploy. With LXD, the host machine handles the drivers and passes the resultant device nodes to the container.

You can do this by adding the following to /etc/modprobe.d/nf as root with your favourite text editor: blacklist amd76x_edac #this might not be required for x86 32 bit users. If the output includes the nouveau module, you will need to blacklist this module to stop it loading in future. You can check with the following command: lsmod | grep nouveau The nouveau driver, installed by default when you elect not to add NVIDIA’s proprietary drivers, may refuse to remove itself. It’s safer to reboot your machine at this point, although this isn’t strictly necessary. To remove your current NVIDIA or open source Nouveau drivers, enter the following: sudo apt remove -purge nvidia* This can be done by entering the following into a terminal: sudo systemctl isolate multi-user.target When working with graphics drivers, it’s best to quit from the X.org graphical environment and work on the command line. We need to make sure these are fully removed before attempting to install a new set. With either a new or old Ubuntu 18.04 installation, it’s likely that you’ll have NVIDIA drivers of one sort or another on your system.
