参考如下视频下载匹配的显卡和安装：
NVIDIA显卡的Ubuntu驱动程序安装方法

删除原有nvidia驱动

如果是apt-get方法安装的驱动

sudo apt-get remove nvidia-*

如果这样卸载不干净则：

sudo apt autoremove -y nvidia* --purge
sudo rm /etc/apt/sources.list.d/cuda*
sudo apt-get autoremove && sudo apt-get autoclean
sudo rm -rf /usr/local/cuda*

如果是run方法安装的驱动

sudo sh NVIDIA-Linux-x86_64-550.120.run -uninstall

---

怎样干净的卸载以前装的nvidia驱动？

安装nvidia驱动

chmod +x NVIDIA-Linux-x86_64-550.120.run

sudo bash  NVIDIA-Linux-x86_64-550.120.run

当没有报错，或者

如果报错Unable to find the kernel source tree for the currently running

Unable to find the kernel source tree for the currently running
kernel. Please make sure you have installed the kernel source files
for your kernel and that they are properly configured; on Red Hat
Linux systems, for example, be sure you have the ‘kernel-source’ or
‘kernel-devel’ RPM installed. If you know the correct kernel source
files are installed, you may specify the kernel source path with the
‘–kernel-source-path’ command line option.

building kernel modules

ERROR: An error occurred while performing the step: “Building kernel

查看之后发现：

warning: the compiler differs from the one used to build the kernel
The kernel was built by: x86_64-linux-gnu-gcc-12 (Ubuntu 12.2.0-3ubuntu1) 12.2.0

解决方法

sudo apt-get install gcc-12 g+±12

安装gcc12

sudo apt-get install gcc-12 g++-12

切换系统中的GCC版本,后面的100是优先级

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-12 100
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-12 100

假如系统中的GCC和G++版本为11,则降低它们的优先级

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-11 90
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-11 90

将gcc g++都切换为12版本，命令如下：

sudo update-alternatives --config gcc

There are 2 choices for the alternative gcc (providing /usr/bin/gcc).

  Selection    Path             Priority   Status
------------------------------------------------------------
* 0            /usr/bin/gcc-12   100       auto mode
  1            /usr/bin/gcc-11   90        manual mode
  2            /usr/bin/gcc-12   100       manual mode
