过去一天，我一直在尝试让 Nvidia 驱动程序在我运行 Lubuntu 16.04.6 LTS 的 10 年老电脑上运行，正如推荐的那样这里自动安装的驱动程序不起作用，所以我输入了glxinfo，结果得到的是
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".

我在网上搜索了一下，参考了以下指南：这个还有很多非常相似的命令，大多建议我安装nvidia-304而不是nvidia-304-updates，我能看到两者之间唯一的两个区别是，该nvidia-304-updates包以 800x600 分辨率运行，而该nvidia-304包以（我认为）1280x800 分辨率运行。我的显示器分辨率是 1280x1024。更重要的是，当运行该序列中的最后一个命令时，sudo nvidia-xconfig我得到以下内容：
Using X configuration file: "/etc/X11/xorg.conf".
Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup'
New X configuration file written to '/etc/X11/xorg.conf'
但这不是重点。为什么显卡驱动程序安装不正确，以及如何正确安装它们？
仅供参考，这是我的系统规格复制粘贴我链接的问题，忽略操作系统、内核等：
