Hello Folks,

This is really annoying and I didn't had that for quite a while.
I bought a Lenovo Thinkpad E550 and installed OpenSuse Leap on it. Work's fine with
the exception of the integrated Webcam.

$ sudo lsusb

$ dmesg | grep uvcvideo

$ lsmod | grep videodev

cheese, libcheese7, libcheese-common, ... are installed. I also installed guvcview.
BIOS is checked. Webcam is enabled.

I searched the Lenovo Website but had no luck.
Do you have any idea how make this work?

Thank's in advance.

Hi Gonzo...

Welcome to the forum

From what I see here and on Google, there appears to be a bug, at least with Ubuntu, although I'm not sure if OpenSUSE is affected or not. I'm not sure how handy you are with the command line but if you want to give it a go, you can try applying one of the two patches offered in the bug report, here and here. Unfortunately, I can't instruct you how to where or how to insert it into the applicable file, perhaps another member can guide you on this.

Also, I can't guarantee this will work for you, try it at your own risk.

Regards...

Hi ardvark,

It is definitely the same issue, but I can't get the patch to work.
https://bugs.launchpad.net/ubuntu/+s...c/+bug/1433906

I was trying this:
uname -a
# check your current kernel version, then download the same version
# note, no root!
apt-get source linux-image-extra-4.2.0-19-generic
# install packages needed to build the kernel
sudo apt-get build-dep linux-image-extra-4.2.0-19-generic
sudo apt-get install git
cd linux-4.2.0
wget -O webcam.patch https://launchpadlibrarian.net/22962...d-UVC_QU.patch
git apply webcam.patch

you can now change the version in debian/changelog, adding "-webcam" or something of the like, which makes it easier to identify your kernel package.

DEB_BUILD_OPTIONS=parallel=4 AUTOBUILD=1 NOEXTRAS=1 fakeroot debian/rules binary-generic
# now wait until kernel is built, this takes some time
sudo dpkg -i ../linux-headers*.deb ../linux-image*.deb

Then, reboot.
You'll have to repeat this process if Ubuntu updates kernel.

But after the after "git apply webcam.patch" I am unsure what to do...

Thank's in advance

Hi...

I'm not sure how to help you here because, in part, you're using OpenSUSE, not Ubuntu. If no one here on the forum can help you, then I would suggest you either take your system to a local LUG (Linux user's group) or to a computer repair shop who is knowledgeable with Linux.

Regards...

I changed to Ubuntu 14.04.3, so that is not the problem anymore.
Checked a few more distributions. So far the problem is reproducible in Debian 8, OpenSuse Leap, Ubuntu 14.04.3 and 15.10.

It's is kinda disappointing that there isn't a approved fix out yet. Could Lenovo be the wrong candidate for Linux Desktops?

Not that I know of.

IBM laptops and Gnu/Linux walk hand in hand.

Usually Thinkpads are fine with Linux: Lenovo actually sold this model without Windows. I couldn't even work out what the camera was, though, when I looked for a driver: some sites said the hardware was Intel, some Chicony.. It does seem possible to get the camera working, as the Gentoo website list it as OK. Personally, I'd consider Gentoo a last resort!
