Step-by-step – CUDA 11 KDE Neon Linux Installation

Installing

2. 2. Pre-Installation Testing

   Then Verify on CUDA Capable GPU.

   lspci | grep -i nvidia

   But if you do Not see any NVIDIA hardware on Output then first install:

   sudo update-pciids

   Then try Again…

3. 3. Installing Kernel Headers

   Next Install KDE Neon’s Kernel Headers.

   sudo apt install linux-headers-$(uname -r)

   If Got “User is Not in Sudoers file” then see: How to Enable sudo.

4. 4. Setting Up CUDA Repo

   See How Setup CUDA 11 Repository for KDE Neon Linux

   CUDA Repository Setup

   CUDA Repo for KDE Neon Linux

5. 5. Installing CUDA 11

   Finally, Install CUDA 11 Toolkit in KDE Neon Linux
   To search for the Available releases:

   sudo apt search cuda | grep 11

   So for instance, to install the complete CUDA 11.6 Release play:

   sudo apt install cuda-11-6

   Where for the CUDA 11.6 Driver only:

   sudo apt install cuda-toolkit-11-6

6. 6. Setting Up Path

   Again Setup PATH Env Variable.
   This is necessary to Find the Binaries on System:

   echo 'export PATH=/usr/local/cuda-11.8/bin${PATH:+:${PATH}}' >> $HOME/.bashrc

   Possibly Amend the 11.8 with the Actual Version…
   And Reload Configuration simply with:

   bash
