[nvidia-installer]:    warning: the compiler differs from the one used to build the kernel
[nvidia-installer]:      The kernel was built by: x86_64-linux-gnu-gcc-12 (Ubuntu 12.3.0-1ubuntu1~22.04) 12.3.0

[nvidia-installer]:    It is recommended to set the CC environment variable
[nvidia-installer]:    to the compiler that was used to compile the kernel.
[nvidia-installer]:
[nvidia-installer]:    To skip the test and silence this warning message, set
[nvidia-installer]:    the IGNORE_CC_MISMATCH environment variable to "1".
[nvidia-installer]:    However, mixing compiler versions between the kernel
[nvidia-installer]:    and kernel modules can result in subtle bugs that are
[nvidia-installer]:    difficult to diagnose.

WARNING: The nvidia-drm module will not be installed. As a result, DRM-KMS will not function with this installation of the NVIDIA driver.
WARNING: nvidia-installer was forced to guess the X library path '/usr/lib' and X module path '/usr/lib/xorg/modules'; these paths were not queryable from the system.  If X fails to find the NVIDIA X driver module, please install the `pkg-config` utility and the X.Org SDK/development package for your distribution and reinstall the driver.
WARNING: This NVIDIA driver package includes Vulkan components, but no Vulkan ICD loader was detected on this system. The NVIDIA Vulkan ICD will not function without the loader. Most distributions package the Vulkan loader; try installing the "vulkan-loader", "vulkan-icd-loader", or "libvulkan1" package.
