不知道这里发生了什么。这是 ubuntu 22.04。重新启动(安装补丁)后,视频设备突然出现故障,最明显的是罗技网络摄像头。我在系统日志中看到的是
Apr 23 20:45:02 orac kernel: [22230.498881] usb 3-6.2: New USB device strings: Mfr=0, Product=2, SerialNumber=1

我认为它一定是 mtp-probe,也许是与 udev 规则有关,但我也对 colord-sane 感到疑惑。
有什么帮助吗?
答案1
正如我的评论:事实证明 mtp-probe 是正常的,colord 消息在重新启动时消失,但权限仍然失败。最终我放弃了,升级到 23.04,无论如何我很快就会这样做。现在它工作正常。
