我最近在戴尔 Latitude 5290 二合一平板电脑上安装了 Ubuntu 18.04。我无法让 Ubuntu 识别的唯一硬件元素是摄像机。从这个线程来看，我的猜测是目前可能没有支持。
那正确吗？
这是我的 lspci

网络摄像头的标签为
Realtek Semiconductor Co., Ltd. Integrated_Webcam_HD，但我没有找到太多关于可能需要哪些驱动程序或是否需要驱动程序的信息。我没有在平板电脑上看到用于激活相机的组合键。
戴尔似乎有Ubuntu 指南。
编辑：我联系了戴尔客户支持，他们认为没有适用于 Linux 的 5290 二合一网络摄像头的驱动程序。呃，好吧。我现在将在没有网络摄像头的情况下使用它。
我有相同的笔记本电脑，并且在安装 Ubuntu 20.04 后正在寻找无法工作的相机的修复程序。不要引用我的话，但软件堆栈上应该有正在进行的工作，最终可能会支持这种内置网络摄像头。我相信这些的内部接口是 MIPI CSI2，而不是通用 USB（通常由开箱即用的 UVC 驱动程序支持）。
同样，我不是专家，但需要对 Intel IPU3 CIO2 的内核支持，这可能在Linux Kernel 5.6中得到支持，加上对 V4L2 等软件堆栈的支持，以及对焦点、白平衡等的软件控制。我确实在 Ubuntu 20.04 中使用 Kernel 5.6 进行了快速测试。相机仍然无法工作，但在 Cheese 相机应用程序中没有显示“未找到设备”，而是显示了不同的消息，例如“捕获视频时出错”。它正在改进，但可能还需要一段时间才能完全支持。
