- 笔记本电脑：联想 ThinkPad SL300，配备集成 Syntek 摄像头 (17ef:480a)
- 操作系统：Xubuntu 16.04.2 LTS，4.8.0-45-通用 64 位
相机适用于 Windows 10 和根据存档帖子它以前在 Linux 上运行过，例如使用 Ubuntu 8.10。
Xubuntu 将我的相机检测为 USB2.0 UVC PC 相机。我尝试了 Skype、Cheese 和 guvcview（结果如下），效果相同：摄像头 LED 灯亮起，但网络摄像头窗口为黑色. 使用以下方式启动应用程序LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so [应用程序]沒有改變任何事情。

这是一个错误还是一个“功能”？
