Internal laptop camera disconnecting and connecting every 30 seconds

lá cờ us
João Pimentel Ferreira

I really need help on this cause I'm getting crazy, and honestly very disappointed with the stability of ubuntu, because I can't have a normal video-conference with anyone and as you can imagine that is a must nowadays. I searched already a lot in google and here and found no stable solution yet.

Since some months ago, the web internal camera of the laptop simply disconnects after 25-30 seconds and then reconnects again. In some video software the camera reconnects and I have to bear with a blink every 30 seconds and in other platforms such as in zoom the video simply freezes.

Features

  • A Toshiba Satellite laptop
  • Ubuntu 18.04 LTS

@waltinator sự cố bắt đầu từ `Ngày 25 tháng 12 14:50:18` với `kernel: usb 1-1.3: Ngắt kết nối USB, số thiết bị 15`. Tại sao USB ngắt kết nối?

tôi tự hỏi tại sao máy ảnh của bạn được công nhận là bàn phím? Ý tôi là phần này `Máy ảnh web TOSHIBA - HD: TOSHIB: được udev gắn thẻ là: Bàn phím` và `Máy ảnh web TOSHIBA - HD: TOSHIB: thiết bị là bàn phím`

@nobody khi tôi thực hiện `xinput list` máy ảnh có xuất hiện ở đó không? Làm thế nào tôi có thể loại bỏ nó?

không, đây là hành vi bình thường. Vui lòng dán `Sudo udevadm test --action=add /sys/class/video4linux/video0` và `Sudo udevadm test --action=add /sys/class/video4linux/video1` vào https://pastebin.com/

Câu hỏi này là trong các ngôn ngữ khác:

Đăng câu trả lời

Hầu hết mọi người không hiểu rằng việc đặt nhiều câu hỏi sẽ mở ra cơ hội học hỏi và cải thiện mối quan hệ giữa các cá nhân. Ví dụ, trong các nghiên cứu của Alison, mặc dù mọi người có thể nhớ chính xác có bao nhiêu câu hỏi đã được đặt ra trong các cuộc trò chuyện của họ, nhưng họ không trực giác nhận ra mối liên hệ giữa câu hỏi và sự yêu thích. Qua bốn nghiên cứu, trong đó những người tham gia tự tham gia vào các cuộc trò chuyện hoặc đọc bản ghi lại các cuộc trò chuyện của người khác, mọi người có xu hướng không nhận ra rằng việc đặt câu hỏi sẽ ảnh hưởng—hoặc đã ảnh hưởng—mức độ thân thiện giữa những người đối thoại.
