GPU驱动安装：An NVIDIA kernel module 'nvidia-uvm' appears to be already loaded in your kernel.-马春杰杰

WARNING: An NVIDIA kernel module 'nvidia-uvm' appears to be already loaded in your kernel. 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. Some of the sanity checks that nvidia-installer performs to detect potential installation problems are not possible while an NVIDIA kernel module is running.

此警告为：系统当前已经加载了 旧版 NVIDIA 模块（nvidia-uvm），安装程序无法在模块仍被占用时替换或重新编译新的驱动模块。

可以查看目前已加载的模块：

root@SDAI202-PowerEdge-T630:~# lsmod | grep nvidia

nvidia_uvm 2097152 30

nvidia_drm 139264 0

nvidia_modeset 1638400 1 nvidia_drm

nvidia 104095744 339 nvidia_uvm,nvidia_modeset

i2c_nvidia_gpu 12288 0

i2c_ccgx_ucsi 12288 1 i2c_nvidia_gpu

解决方案：

sudo systemctl stop gdm
sudo systemctl stop lightdm
sudo systemctl stop sddm
sudo systemctl stop nvidia-persistenced
sudo rmmod nvidia_uvm nvidia_drm nvidia_modeset nvidia
sudo modprobe -r nvidia_uvm nvidia_drm nvidia_modeset nvidia

sudo systemctl stop gdm

sudo systemctl stop lightdm

sudo systemctl stop sddm

sudo systemctl stop nvidia-persistenced

sudo rmmod nvidia_uvm nvidia_drm nvidia_modeset nvidia

sudo modprobe -r nvidia_uvm nvidia_drm nvidia_modeset nvidia

如果以上还不可以，说明有人占用了显卡：
