Hossein's questions

安装 Ubuntu 20.04 后，我注意到我根本没有声音。我还安装了 22.04 认为可能较新的版本已经解决了这个问题，结果证明是错误的。22.04 也存在这个问题。
这是lspci -v重要的情况下的输出：

如您所见，似乎检测到了音频设备，但仍然没有任何声音！
我该如何解决这个问题？

更新1：

我注意到后面板的声音似乎还可以，但前面板没有声音。我检查了前面板和后面板在windows下都有声音，但前面板仅在ubuntu中不起作用！这怎么可能？这仍然是驱动程序问题吗？

安装CUDA工具包并cuDNN成功安装后没有任何问题，每当我这样做时：

sudo ldconfig 

我得到：

/sbin/ldconfig.real: /usr/local/cuda/lib64/libcudnn.so.7 is not a symbolic link

错误信息。
是什么原因，我该如何解决？

顺便说一句，我是这样安装cuDNN的：

 # cuDNN, extracts to a folder named cuda
 tar xvf cudnn*.tgz  
 cd cuda  
 sudo cp lib64/* /usr/local/cuda/lib64
 sudo cp include/* /usr/local/cuda/include

ls -lha libcudnn*in的输出/usr/local/cuda/lib64如下：

breeze@breeze:/usr/local/cuda/lib64$ ls -lha libcudnn*
-rwxr-xr-x 1 root root 275M آوریل 15 12:03 libcudnn.so
-rwxr-xr-x 1 root root 275M آوریل 15 12:03 libcudnn.so.7
-rwxr-xr-x 1 root root 275M آوریل 15 12:03 libcudnn.so.7.0.5
-rw-r--r-- 1 root root 268M آوریل 15 12:03 libcudnn_static.a

基本上我想捕捉在 Ubuntu 中安装驱动程序的过程，以便稍后观看。

有诸如 SimpleScreenRecorder 之类的屏幕捕获应用程序，但它们无法在文本模式下工作，因为当我停止 LightDM 时没有显示驱动程序。

还有一个可以让我们在文本模式下截屏，但我想知道当我切换到+ +fbcat时，是否有什么可以用来截屏的？CtrlAltF2

我想知道我是否可以轻松安装多个 Cuda 工具包并使用它们。
原因是，我有两个应用程序，需要两个不同的版本。
现在如果我创建两个用户帐户，并在每个帐户中安装每个版本，可以吗？
我的意思是它们不会影响整个系统并因此影响其他帐户吗？
我可以在一个帐户中执行此操作吗？

提前致谢

我正在尝试像这样在 ubuntu14.04 中安装 Anaconda3：

seyyedhossein@hossein:~$ sh Anaconda3-4.2.0-Linux-x86_64.sh 

我得到：

这里有什么问题？
我已成功将其安装在另一个帐户（最初是从该帐户下载的）上。但是当我登录到我的新帐户时，它就无法运行！
