[Kernel-packages] [Bug 1737536] Re: Webcams not working on a Dell Latitude 5285 laptop
A detailed answer to this problem is provided here: https://www.spinics.net/lists/linux-media/msg131388.html In summary, these "complex" webcams need drivers both in kernel space and user space, and it will take some time before they are supported under linux. If ubuntu devs can help to speed up the development of these drivers, this would be appreciated! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1737536 Title: Webcams not working on a Dell Latitude 5285 laptop Status in linux package in Ubuntu: Triaged Bug description: I installed ubuntu 17.10 on a Dell latitude 5285 detachable laptop.

After some research, it seems the webcams depend on a new intel driver which will be released in kernel 4.16: https://www.mail-archive.com/linux-media@vger.kernel.org/msg122619.html -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1737536 Title: Webcams not working on a Dell Latitude 5285 laptop Status in linux package in Ubuntu: Incomplete Bug description: I installed ubuntu 17.10 on a Dell latitude 5285 detachable laptop.
