nvidia英伟达GPU:nvidia driver is not loaded

最近在开fastai提供的AI教程,刚好自己的电脑上有nvidia独显(GPU),先前因为耗电温度高就切换到了内置显卡.是时候实现你的价值了nvidia,出来吧小宝贝.执行召唤咒语:nvidia-settings后傻眼了:

ERROR: NVIDIA driver is not loaded

ERROR: Unable to load info from any available system

(nvidia-settings:317): GLib-GObject-CRITICAL **: 06:42:43.821: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

** Message: 06:42:43.855: PRIME: No offloading required. Abort

** Message: 06:42:43.855: PRIME: is it supported? no

执行nvidia-smi也是报同样的错误,驱动没了,难道我上次切换显卡时直接把驱动也卸载了,什么时候残忍的斩草还除根了?实在想不起,还是先重新安装下吧:

sudo add-apt-repository ppa:graphics-drivers/ppa  

sudo apt-get update  

sudo apt-get install nvidia-460 #此处要根据上面查询到的版本适当更改

sudo apt-get install mesa-common-dev  

sudo apt-get install freeglut3-dev

安装挺顺利的,确认下安装日志也没发现什么问题:

[email protected]:spark$ sudo apt-get install nvidia-driver-460

为了安全期间又重启了下电脑,再次召唤nvidia,还是熟悉的配方熟悉的味道.

这就有点诡异了,找gpu管理员了解下情况吧:

GPU管理员一通报告,我就注意到了一条可能有用的信息:

屏蔽啦?屏蔽这活应该是modprobe干的,那就去检查下modprobe吧:

$ ls /lib/modprobe.d/

aliases.conf

blacklist_Linux_4.15.0-137-generic.conf

blacklist_Linux_4.15.0-141-generic.conf

blacklist-nvidia.conf

fbdev-blacklist.conf

nvidia-graphics-drivers.conf

systemd.conf

看到blacklist-nvidia.conf文件了吧,人赃俱获还真是modprobe干的.就这么顺利吗?现实情况是我第一次检查的/etc/modprobe.d文件夹,没有发现可疑文件,就放过modprobe了.好一通搜索无果后才有找到另一个巢穴/lib/modprobe.d文件夹,哎呦这小子啥时候还狡兔三窟了.

费了这么大劲找到了屏蔽nvidia gpu的配置文件,不得拉出来示个众:

cat /lib/modprobe.d/blacklist-nvidia.conf

# Do not modify

# This file was generated by nvidia-prime

blacklist nvidia

blacklist nvidia-drm

blacklist nvidia-modeset

alias nvidia off

alias nvidia-drm off

alias nvidia-modeset off

从注释信息看,这文件是nvidia-prime生成了,还真是干了事后留签名,敢干敢当.

删了吧:

rm blacklist-nvidia.conf  

这里注意只删blacklist-nvidia.conf文件就可以了,不要把nvidia-graphics-drivers.conf文件也删了,虽然名字里都带nvidia.

安全期间再执行下:

sudo update-initramfs  -u

重启.

这下终于可以成功召唤出这几年随着机器学习声名鹊起的NVIDIA了:
