What Do I Do If "Unable to load the kernel module 'nvidia.ko'" Is Displayed During Driver Installation?

Possible Causes

  1. The bus is disconnected.

  2. The kernel versions are inconsistent.

Impact

The graphics card driver fails to be installed and the graphics card cannot be used.

Solution

  1. Run the following command to check whether the kernel versions are consistent:

    rpm -qa | grep gcc #Check the GCC version.

    rpm -qa | grep kernel-devel #Check the kernel-devel version.

    • If the kernel versions are inconsistent, reinstall the driver.
    • If the kernel versions are consistent, go to the next step.
  2. View the dmesg log and check whether there are NVRM errors.
    • If the error message "NVRM: fallen off the bus and is not responding to commands" is displayed, the bus is disconnected. Then, contact technical support to replace the graphics card.
    • If the fault persists, collect fault information by referring to Fault Information Collection and contact technical support.
