I have had a problem with having the integrated webcam to be recognized
by various applications (cheese, Microsoft Teams [yes...], Zoom, etc).
It does work sometimes and it doesn't at other times.
I have various kernels installed (4.9.0-11-amd64 all the way through
4.9.0-14-amd64) and rebooting into each of these kernels won't make much
difference.
I have uninstalled, purged and reinstalled build-essential
linux-headers-`uname -r` linux-image-amd64`uname -r` (for each of the
kernel versions) and usbutils, and I have also uninstalled tlp, but it
doesn't seems to make much difference.
This is the full log of `dmesg|grep video` of today, when I had the last
failure:
https://paste.debian.net/plainh/1c22d1aa
I can't upgrade to Debian stable for a number of reasons that it will
take to long to explain and I have to stick with Stretch for the time
being. I've only had this problem for the last 6 months, presumably
after some upgrades.
Any help will be appreciated.
Hi Ottavio,
if the issue with your camera is a kernel thing then you can install
newer kernel from backports.
According to this page -
https://tracker.debian.org/pkg/linux
Linux 4.19.118 is available for Debian 9.
I've added the stretch-backports repos and installed the new kernel and
headers:
$ uname -r
4.19.0-0.bpo.9-amd64
But it doesn't seem to have sorted much out. The camera gets recognised
for a few minutes and then it stops.
