ubuntu 23.04 无法检测到我的内置网络摄像头。Ubuntu 安装在外部 SSD（三星 T7 500GB）上，我使用的是三星 Galaxy Book 3 Pro
我在网上尝试了很多方法。我主要在笔记本电脑上运行 Windows 11，网络摄像头可以正常工作。这里没有硬件问题。
我的笔记本电脑有一个用于阻止网络摄像头的键，它在 Windows 上有效，但在 Ubuntu 上“不起作用”。如果我按下它，什么也没发生。重新启动应用程序或重新启动后，按下该键没有任何作用。
我尝试使用 Cheese 和 Microsoft Teams 打开网络摄像头。如果我连接 USB C 网络摄像头（如 logitech streamcam），它就可以正常工作。我在外部 SSD 上安装了 Ubuntu 22.04 进行测试，但这也没有用。
我的声音也不起作用（尽管这是一个单独的问题）。
如果我运行v4l2-ctl --list-devices我收到的消息是Cannot open device /dev/video0, exiting.
我试过了lspci -nnk，但没有检测到网络摄像头

如果我运行sudo v4l2-ctl --list-devices输出是Cannot open device /dev/video0, exiting.
从ls -l /dev/video输出来看ls: cannot access '/dev/video': No such file or directory
该命令ls -l /dev/video0 ;id给出输出ls: cannot access '/dev/video0': No such file or directory uid=1000(andre) gid=1000(andre) groups=1000(andre),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),100(users),118(lpadmin)
答案1
也许你需要在 bios 中启用网络摄像头
或者你可能需要给予它权限
我不确定，但请尝试：
sudo chown root:video /dev/video0
sudo chmod 666 /dev/video0
我希望它能帮助你
答案2
不幸的是，我认为你运气不好（假设它是和我的 Book 3 Pro 360 中相同的 OV02C10 传感器。）目前正在进行一项工作，以使新的英特尔 IPU6 连接摄像头能够正常工作这里但是它们距离进入主线内核还有很长的路要走，而且 OmniVision 传感器似乎还无法工作——我一直在研究驱动程序，并设法让设备被识别，但没有各种寄存器和时钟设置的数据表，我现在陷入了困境。
底线是，除非某人既有适当的动机和当适当的数据出现时，您可能需要等待一段时间 - 因此外部网络摄像头是目前唯一的出路。
