Viber does not detect camera after Ubuntu version upgrade

**Andreyshel** · August 5th, 2024

Viber does not detect my camera while Google meet and Cheese work just fine.
This problem started after upgrade( reinstall with /home remaining not formatted) from Ubuntu 22.04 to 24.04.
Viber 21.8.0.11(Installed via official deb, but have tried appimage version as well with no effect)
Kernel 6.8.0-39-generic
Camera: Bus 001 Device 003: ID 046d:082d Logitech, Inc. HD Pro Webcam C920

I wanted to start lshw -c USB to show information about camera driver but this command hangs on Network interfaces.

Thank you for any ideas.

X11 or Wayland? In theory, that shouldn't matter for a webcam.

My C920 died after 8 yrs and I haven't replaced it. When I plug it in via USB, I see this:

Code:

$ dmesg -w

Do you see something similar? There should be 2 devices - 1 for video and 1 for the microphone. The video device gets listed in /dev/video* - I have a few video devices there, so don't know which is which. I have a Magewell capture card too which is different than a webcam but shows up as a /dev/video* device.

Code:

$ lsusb
...
Bus 001 Device 057: ID 046d:c341 Logitech, Inc. HD Pro Webcam C920
Bus 001 Device 077: ID 046d:082d Logitech, Inc. HD Pro Webcam C920
...

I don't use viber. I do have OBS loaded and that is working with the camera and X11. Yep. Just tested. Though I don't have 24.04. Too new for my needs. I'm still on 20.04. Stability is more important to me than "new". I will be using X11 for as long as possible. Wayland breaks a number of my workflows, unfortunately. Wayland closes some security holes in X11 that are needed for those workflows to actually work. I don't know if Wayland or X11 matter at all. Just something that could break video handling and it is an easy thing to switch for a quick test.

Have tried both without an effect.

Interesting. In lsusb output there is only one. Dmesg output is simular. But the same is the case for 22.04.3 livecd. So it should not be a problem

Believe answer of wooque user is the solution. Tried to implement but simply too many packages need to be installed manually.

Downgrade to 22.04 is almost more reasonable in this case.
