如何在Ubuntu22.04LTS中正确安装NVIDIA RTX驱动程序？

Question

我买了一台带有GPU RTX 3050手机的游戏笔记本电脑。因为我想把它用于机器学习和深度学习，所以我想确保我能正确地访问它的显卡。

到目前为止，我已经试过：

ubuntu-drivers devices

然后：

sudo ubuntu-drivers autoinstall

它给了我一个错误：

    Traceback (most recent call last):
  File "/usr/bin/ubuntu-drivers", line 513, in <module>
    greet()

我也有同样的问题。我的解决方案是编辑detect.py命令

sudo gedit /usr/lib/python3/dist-packages/UbuntuDrivers/detect.py

然后滚动到第835行。

将代码行更改为

version = int(package_name.split('-')[-2])

保存并关闭您的文件。您也可能希望重新启动。

显然，这是一个bug，因为一些驱动程序以一个单词而不是一个整数结尾。欧共体司机-名字-525-打开。此代码调整采用525个整数值。
