Linux General

I got my dell xps yesterday. It is the developers edition that come with ubuntu 16.04 preinstalled. 

I notice that cheese does not come installed, so I installed but no webcam is detected. I can see it if I do an lsusb, so I know is activated.

I was wondering, does this laptop supports the webcam or not?

Edit: Good news, a dell engineer came and replace the monitor, that has the webcam integrated and presto, it is working now.

Update: Most of the problems with the webcam is not hardware based. Looks like many of the laptops come with a firmware that the latest Linux kernel do not support at the moment. To solve the issue, Dell is replacing the whole monitor with a downgrade firmware of the webcam. If a less drastic solution is reported, I will update the post with it.

Update2: Looks like there is a software solution now.

Neither the official solution above, nor going to pre-release worked.  Also, I regret this last move.  Any way to reverse it?

FYI, the patch will land on Fedora 27 and 28 testing-update next week, and should be release in regular update in 2 weeks or so. The patch is integrated with Linux 4.17.

I'm running the git version right now and it's working quite well.

Thanks for the info!

I currently have the latest software and firmware installed, and the webcam works when I first boot my laptop. However, after waking from suspend, the webcam no longer works. Is this a known issue?

I am having the same issue with the webcam not working after suspend.

There is a problem with the hwe kernel: it does not wake up after the laptop has been hibernating.

I have the same problem with the webcam not working after suspending the laptop.
I'm using the 4.15.0-24-generic kernel under Ubuntu 18.04.
This started after I configured the laptop to go into deep sleep, which you can check using the command 

> cat /sys/power/mem_sleep
s2idle [deep]

Same issue - installed 18.04, enabled deep sleep, webcam doesn't work after deep sleep.

[MatveyME]

The same problem.

Kubuntu 18.04 with 4.15.0-24-generic kernel, enabled deep sleep, webcam doesn't work after deep sleep. But I enabled Hibernation - after hibernation webcam works.

Who has ideas how to fix this?? Thanks in advance!
