由于整个 Covid-19 的情况，我需要能够在我相对较新的 Dell Vostro 5590 笔记本电脑上使用 Skype。不幸的是我无法让网络摄像头工作。它向我显示了一个黑屏（在 Skype 和 Cheese 等中）。我还安装了 guvcview，但事实证明这没有用。它是一个集成的高清网络摄像头。我已经检查过我的用户是否已添加到视频组中。
感谢您的帮助...是否有我可以安装的特殊 Linux 驱动程序？
不确定要提供什么信息，但这是输出lsusb：
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 0bda:565a Realtek Semiconductor Corp.
Bus 001 Device 003: ID 8087:0aaa Intel Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
并lspci给出
00:00.0 Host bridge: Intel Corporation Device 9b61 (rev 0c)
00:02.0 VGA compatible controller: Intel Corporation Device 9b41 (rev 02) …我需要在 Ubuntu 18.04 上安装并编译 SURFEX 代码。为此，我遵循此处的文档。一切进展顺利，直到我尝试使用make. 我收到错误 127。我查了这个错误的含义，但我不太明白它在这种情况下的含义。非常感谢任何帮助。
完整消息如下
