我刚刚安装了 18.04 MATE。我有两个摄像头可用，一个是内置的，另一个是 USB 摄像头。在 16.04 中，cheese 可以看到这两个摄像头（Cheese->Preferences->Webcam）。在 18.04 中，cheese 只注册了内置摄像头。但是，guvcview 和 vlc 可以看到另一个摄像头。我尝试使用 dconf 编辑器，但没有效果。
dsmesg 报告：

有人有什么建议吗？或者这只是一个错误？
谢谢

dmesg 报告中的问题无害，不会影响 Cheese。以下是有关消息的详细信息：https://bugzilla.kernel.org/show_bug.cgi?id=111291#c9
