Dell G5 5500笔记本ubuntu系统安装nvidia rtx 2060显卡驱动

将dell g5 5500安装ubuntu系统,在ubuntu安装nvidia独显驱动,提示如下:

The target kernel has CONFIG_MODULE_SIG set,which means that it supports cryptographic signatures on kernel module. On some systems, 
the kernel may refuse to load modules without a valid signature from a trusted key.This system also UEFI Secure Boot enabled; 
many distributions enforce module signature verification on UEFI systems when Secure Boot is enabled. 
Would you like to sign the NVIDIA kernel module?
该报错需要关闭bios的安全启动模式,新版的bios在boot configuration选项中,有security boot选项,选择关闭即可。
(旧版本的bios更好找一点。),新版本bios修改如下:

然后再安装显卡驱动,发现显卡已经可以正常显示。
