A100 V100 Driver not working

Hello, I have problem installing nvidia drivers 515.65.01 on Ubuntu 22.04. Here is what I have tried so far.

  1. lspci | grep -i nvidia confirms both card (A100, V100) can be physically detected.

  2. lsmod | grep nouveau return null, confirms the nouveau is added to the blacklist

  3. lsmod | grep Nvidia return nvidia package is installed

  4. NVIDIA X server settings only display V100 configuration, same for running nvidia-smi

  5. I confirm the server has been properly rebooted after the installation.

After installation, only V100 is detected in NVIDIA-SMI, never the A100. Anyone having the same issues?

Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.

Hi Generix,

pci=realloc=off works perfectly. Thanks a lot!

Try this:

  1. nano /etc/default/grub
  2. update GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash pci=realloc=off”
  3. save your grub file and update-grub
