Ubuntu安装nvidia显卡驱动后无网络WIFI蓝牙

本教程在Ubuntu22版本下，安装nvidia显卡驱动后出现无法使用网络WIFI蓝牙的情况，主要问题是默认启动内核的原因，修改默认启动内核即可。

查看当前系统所有的内核版本

grep menuentry /boot/grub/grub.cfg

从输出查看总共有三种可以切换的内核版本，选择要切换的版本，使用下面代码查看当前内核版本

uname -r
1

查看当前启动入口ID

grep submenu /boot/grub/grub.cfg
1

输出

submenu 'Advanced options for Ubuntu' $menuentry_id_option 'gnulinux-advanced-5acffe8e-c48f-4e6c-9b68-9a7770bac9fa' {
1

取出当前版本启动入口ID “gnulinux-advanced-5acffe8e-c48f-4e6c-9b68-9a7770bac9fa”

如果我想将内核版本切换为4.15.0-193-generic，使用下面代码输出该版本启动入口ID

grep gnulinux-4.15.0-193-generic-advanced /boot/grub/grub.cfg
1

输出

menuentry 'Ubuntu, with Linux 4.15.0-193-generic' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-4.15.0-193-generic-advanced-5acffe8e-c48f-4e6c-9b68-9a7770bac9fa' {
1

取出切换版本启动入口ID “gnulinux-4.15.0-193-generic-advanced-5acffe8e-c48f-4e6c-9b68-9a7770bac9fa”

最后编辑/etc/default/grub文件，将GRUB_DEFAULT=0的值修改为“当前版本启动入口ID > 切换版本启动入口ID”

GRUB_DEFAULT="gnulinux-advanced-5acffe8e-c48f-4e6c-9b68-9a7770bac9fa>gnulinux-4.15.0-193-generic-advanced-5acffe8e-c48f-4e6c-9b68-9a7770bac9fa"

保存文件后，更新 Grub 配置，并重启

update-grub
