ubuntu 安装NVIDIA驱动或CUDA报错：“The driver installation is unable to locate the kernel source....” 或者是无法登录

ubuntu 安装NVIDIA驱动或CUDA报错：“The driver installation is unable to locate the kernel source....” 或者是无法登录系统界（loop login )

主要原因更主板的BIOS设置有关！！

UEFI下的设置

这里首先要重启，华硕主板按Delete或者F2进入UEFI界面。

UEFI禁用Fast Boot

进入UEFI后，按F7进入Advanced Mode，在Boot菜单下，将Fast Boot改为Disable。

方法一：

 Disable UEFI Secure Boot (if possible), or use a kernel that doesn't require signed modules.How to disable Secure Boot on Ubuntu, then!?!?

Since Ubuntu kernel build 4.4.0-21.37 this can be fixed by running:

sudo apt install mokutil
sudo mokutil --disable-validation

Since questions may arise, see third party kernel modules on UEFI with enabled Secure Boot and the consequences of disabling it.

方法二：

重启机器按F2 进入BIOS系统，找到Boot （启动）选项

（1）Security 中的 Secure Boot 如果是Windows UTFILE system ，务必设置为“Disabled" （一般设置这个就可以了）

卸载：

4.6. Uninstallation

To uninstall the CUDA Toolkit, run the uninstallation script provided in the bindirectory of the toolkit. By default, it is located in /usr/local/cuda-9.0/bin:

$ sudo /usr/local/cuda-9.0/bin/uninstall_cuda_9.0.pl

To uninstall the NVIDIA Driver, run nvidia-uninstall:

$ sudo /usr/bin/nvidia-uninstall

To enable the Nouveau drivers, remove the blacklist file created in the DisablingNouveau section, and regenerate the kernel initramfs/initrd again as described in thatsection.
