解決nvidia驅動 安裝 報'nvidia-drm'問題

參考該博文  https://blog.csdn.net/fdqw_sph/article/details/78745375

一臺ubuntu 16.04 機器重裝顯卡驅動，

查看linux 版本內核  username -a

進入對應內核路徑

cd /lib/modules/4.4.0-83-generic/kernel/drivers/gpu/drm/nouveau 
sudo rm -rf nouveau.ko 
sudo rm -rf nouveau.ko.org

仍報如下錯 

An NVIDIA kernel module 'nvidia-drm' appears to already be 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. Please be sure to exit any 
programs that may be using the GPU(s) before attempting to upgrade your driver.

於是 cd /lib/modules 目錄下 ，找了下 內核版本--generic/kernel/drivers/gpu/drm/nouveau

存在 nouveau.ko  nouveau.ko.org

執行

sudo rm -rf nouveau.ko

sudo rm -rf nouveau.ko.org  

後重啓，可以正常安裝顯卡驅動
