This may be because it is in use (for example, by an X server, a CUDA program, or the NVIDIA Persistence Daemon),
but this may also happen if your kernel was configured without support for module unloading. Please be sure to exit any programs that may be using the GPU(s) before attempting to upgrade your
driver. If no GPU-based programs are running, you know that your kernel supports module unloading, and you still receive this message, then an error may have occured that has corrupted an NVIDIA
kernel module's usage count, for which the simplest remedy is to reboot your computer.
然后安装的时候，最后就会出现“unable to load the “nvidia-drm” kernel module”
