我是 Linux 的新手（通过安装强迫自己学习），但使用 Windows 已经大约 20 年了。
我买了一台装有 Windows 的二手 Dell Latitude E7450，把它彻底清理干净，然后安装了 Ubuntu 18.04。大多数东西都正常工作，但集成的网络摄像头却不行：当我打开 Skype 并检查视频时，LED 灯亮了，但没有显示图像。Cheese 显示空白，选项变灰。
hardinfo 输出显示被标识为“SPCA2082 PC CAMERA”的“输入设备”。
您能帮我看看我应该去哪里找吗？我查看了戴尔支持网站，但除了 BIOS 之外没有其他特定的 Ubuntu 驱动程序。提前谢谢您。
以下是lsusb&的一些输出lspci
