Samuel Osoba's questions

自去年以来安装了 Ubuntu，除了内置麦克风外，一切都在我的 PC 上运行，就像在我移除的 Windows 10 操作系统上一样：

以下是我的设备配置：

~$ sudo lspci -knn | grep Audio -A3
00:1b.0 Audio device [0403]: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20] (rev 04)
    DeviceName:  Onboard Audio
    Subsystem: Dell Precision M4600 [1028:04a3]
    Kernel driver in use: snd_hda_intel
    Kernel modules: snd_hda_intel
--
01:00.1 Audio device [0403]: NVIDIA Corporation GF108 High Definition Audio Controller [10de:0bea] (rev a1)
    Subsystem: Dell GF108 High Definition Audio Controller [1028:14a3]
    Kernel driver in use: snd_hda_intel
    Kernel modules: snd_hda_intel
03:00.0 Network controller [0280]: Qualcomm Atheros AR9485 Wireless Network Adapter [168c:0032] (rev 01)

我还使用以下命令查询了我的音频设备cat /proc/asound/card*/codec* | grep Codec是我的结果：

cat /proc/asound/card*/codec* | grep Codec
Codec: IDT 92HD90BXX
Codec: Nvidia GPU 14 HDMI/DP
Codec: Nvidia GPU 14 HDMI/DP
Codec: Nvidia GPU 14 HDMI/DP
Codec: Nvidia GPU 14 HDMI/DP

我还下载了 vokoscreen 来检查脉冲和 alsa-server 选项并进行测试，这些测试产生了失败的结果，除了噪音之外，没有任何音调被捕获。

请参阅下面我的测试选项的屏幕截图：

在使用 VokoScreen 测试失败后，我使用工具的最后一步是下载 QasMixer，打开 QasMixer 后，我有以下屏幕截图：

最初，当我打开 QasMixer 时，根本没有选择 12:00db 的 Mic 线，所以我选择了它，这意味着我启用了，所有这些努力只导致 MIC 图标显示在我屏幕右上角的扬声器图标旁边带有音量指示器，但麦克风仍然无法正常工作。

我还能做错什么。？

上周在我的 Dell Precision 4600 Nvidia 1000M 2GB 显卡上安装 Davinci Resolve 17 后，我观察到该软件没有检测到我的 GPU 硬件；经过一些黑客攻击，我能够绕过它。

现在，在编辑视频后，当我单击“交付”选项卡时，出现了一个新问题；该应用程序立即冻结。经过多次努力解决这个问题，没有任何效果，当我点击交付选项卡时它继续挂起。

现在我选择了 KDenLive，它似乎工作得很好。

我现在的问题是:: 如何卸载 DaVinci Resolve，我实际上是使用 .run 文件安装它并使用 MakeResolveDeb 构建一个 .deb 安装。

我在 4 个月前完全切换到 Linux。我已经能够在我的 Ubuntu 20.04 中安装 Anaconda，但我观察到一些令人头疼的事情。

设置环境后，我需要将它使用的 Python 版本从 3.10 更改为 3.8。所以我使用了这些命令：

conda activate my_env  
conda install python=3.8

这是在 Anaconda 中执行此操作的标准方式。

然而，我观察到它会将新的 Python 3.8 包下载到环境中，尽管我的系统上已经预装了 Python 3.8。

如何配置我的conda环境以使用系统上已安装的现有 Python 版本，而无需从 Internet 下载副本？

尝试了许多标准终端命令来删除安装后出现的 Ubuntu 20.04 的 Telegram。所有命令都返回错误：系统上没有类似的应用程序，但我一直在通用应用程序列表中看到该应用程序，我也可以打开它，但无法登录。我尝试了以下命令：

samuelson@syncserve:~$ flatpak uninstall org.telegram.desktop/x86_64/stable
Command 'flatpak' not found, but can be installed with:

所以，我认为我需要通过命令检查所有路径目录是否存在；因此我使用下面的命令来检查电报的所有可能路径：

find / -iname "*telegram*" 2>/dev/null

该命令的输出令人惊讶，它是电报目录的长列表，见下​​文。

我的问题是如何删除该程序？

samuelson@syncserve:~$ find / -iname "*telegram*" 2>/dev/null
