Ubuntu 19.10 / 20.04网络摄像头崩溃
提问于 2020-05-26 06:21:06
以下是这个问题的后续：梅林U 740 USB2.0摄像头不工作
基本上我有梅林U740 USB2.0摄像头。我设法使它在Ubuntu18.04上工作，直到我升级到19.10，它才正常工作。后来升级到20.04并没有什么区别，现在相机不能工作了。
它得到了系统的认可，并在Zoom、Slack和Cheese中启动，几秒钟后就失败了，导致Zoom在一段时间内冻结/失去响应(多达30，其他应用程序似乎能更好地处理它)。我尝试了我的电脑上所有可用的USB端口，但没有什么不同。
我运行了常用的命令，下面是结果：
lsmod | grep video

我有Ubuntu19.10，几天前也面临过这个问题。原因是从5.3.0-53内核更新到5.3.0-55内核.作为解决办法，您可以在GRUB中选择53个版本。对于20.04内核版本，5.6.15应该可以工作：最近内核更新后，摄像头停止了工作。
