Feedback on the Lenovo ThinkPad Edge E550 - GordonBDW

Asked by Victor van der Lee

Webcam not found on Lenovo Thinkpad E550. I'm finding this issue on recent posts but no answers yet. Webcam runs fine in Windows but I prefer to use Ubuntu. Since I bought this laptop specifically for its certification, I'm hoping for an answer, so I can have Skype conversations again with my family abroad.

Hi Victor!

Can you tell me what version(s) of Ubuntu you've tried so far?

Also, could you please provide the output of the following command?

    sudo lsusb -v

(in order to launch this command, you may want to open a terminal by pressing Ctrl+T)

Thanks,

Oops, my bad: to open the terminal, you need to press Ctrl+Alt+T (or access it from the Dash)

Hi Pierre,

I am now using 14.04. Have also tried 15.04. I'm not entirely new to Ubuntu but thusfar I have made my way by copying command strings into terminal following solved issues on Ubuntu forums. This one was too hard. The output of sudo lsusb -v is:

Hi Victor and thanks for the feedback.

Thanks to the output I could determine your laptop is using an Acer webcam (specifically, ID [5986:055a]). There is already an open issue regarding this problem (lp:1433906), I've linked it to your question. Hopefully it will be corrected soon.

Cheers!

Hi Pierre,

What happens when the bug gets corrected? Will it become part of an update or will I have to do something myself?

Hey Victor,

usually, drivers for webcams and the like are handled directly into the Linux kernel. That's why we often recommend people with issues similar as yours to try with the latest Ubuntu release (that comes with a pretty recent Linux kernel) to see if it fixes their problem.

Ubuntu 15.10 is available as a Beta release[1], so if you have some time, you can try it out using a live USB drive to see if it fixes your problem. Ubuntu 15.10 comes with Linux kernel v4.2[2] so it might worth trying it.

If it still doesn't work even with Linux kernel v4.2, it might be a good idea to report this in the bug I mentioned above, so that we can investigate a bit more on how to fix the issue and push it upstream (for other Linux distributions to use).

Hope this helps!
