Internal laptop camera disconnecting and connecting every 30 seconds

drapel 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

Urmăriți `sudo journalctl --follow | tee jc.log` timp de câteva minute în timp ce camera se comportă prost.

@waltinator mulțumesc foarte mult, într-adevăr, în momentul în care a apărut problema, jurnalul a scos mult mai multe informații. Am editat întrebarea în consecință, ați putea să aruncați o privire? Multumesc din nou

@waltinator problema începe la `25 decembrie 14:50:18` cu `kernel: usb 1-1.3: deconectare USB, numărul dispozitivului 15`. De ce se deconectează USB?

Mă întreb de ce camera ta este recunoscută într-un fel ca tastatură? Mă refer la aceste părți `Camera web TOSHIBA - HD: TOSHIB: este etichetat de udev ca: tastatură` și `Camera web TOSHIBA - HD: TOSHIB: dispozitivul este o tastatură`

nu, acesta este un comportament normal. Vă rugăm să lipiți `sudo udevadm test --action=add /sys/class/video4linux/video0` și `sudo udevadm test --action=add /sys/class/video4linux/video1` pe https://pastebin.com/

întrebarea această in alte limbi:

Postează un răspuns

Majoritatea oamenilor nu înțeleg că a pune multe întrebări deblochează învățarea și îmbunătățește legătura interpersonală. În studiile lui Alison, de exemplu, deși oamenii își puteau aminti cu exactitate câte întrebări au fost puse în conversațiile lor, ei nu au intuit legătura dintre întrebări și apreciere. În patru studii, în care participanții au fost implicați în conversații ei înșiși sau au citit transcrieri ale conversațiilor altora, oamenii au avut tendința să nu realizeze că întrebarea ar influența – sau ar fi influențat – nivelul de prietenie dintre conversatori.
