[SOLVED] Webcam Not Detected At All (Lenovo X220 Tablet)

Hey all,

I recently bought a brand new Lenovo X220T / X220 Tablet. It's working great with Arch, with one huge problem: the kernel seems to have no idea that I have a webcam.

Kernel:

Re: [SOLVED] Webcam Not Detected At All (Lenovo X220 Tablet)

What's the output of 

ls -1 /dev/input/event*

I'm not sure if x220 is the same as x220t - here a (Windows) user reports that the camera is manufactured by Ricoh, not Chicony.

A fresh thread http://forums.opensuse.org/english/get- … ost2368058
For some Archers it seems to work out of the box https://bbs.archlinux.org/viewtopic.php?id=119332

Thanks for the replies.

I booted into Ubuntu, hoping that maybe I'd get different output in a different distro. The results:

ubuntu@ubuntu:~$ ls -1 /dev/input/event*

So, Ubuntu shows this 8087:0024 USB device, which is some sort of "Rate Matching Hub", but does not show the Ricoh device which Arch showed (and which I'm hoping is my webcam).

Generally speaking, what are my options if there is a physical device that doesn't even show up in lspci/lsusb at all? I noticed that in the Arch thread with the not-working Wacom, it at least showed up in lspci and whatnot.

Re: [SOLVED] Webcam Not Detected At All (Lenovo X220 Tablet)

Sorry, but I think that Ricoh thing is a card reader https://bugs.launchpad.net/ubuntu/+sour … bug/787606

Does Ubuntu have a 'lsinput' command? If it does, what's the output?
Here you have somebody with Ubuntu 11.04  on Lenovo x220. He got 9 device numbers from /dev/input/eventn ...

Re: [SOLVED] Webcam Not Detected At All (Lenovo X220 Tablet)

I'm back in Arch, I'll try `lsinput`  in Ubuntu again in one second. But first, check this out:

^_^[ryan@bearden:~]$ ls -1 /dev/input/event*
/dev/input/event0
/dev/input/event1
/dev/input/event10
/dev/input/event2
/dev/input/event3
/dev/input/event4
/dev/input/event5
/dev/input/event6
/dev/input/event7
/dev/input/event8
/dev/input/event9

Way more output in Arch. I wonder if that ... matters at all.

That's what I wrote when I edited my previous post ;P Sorry.
There's a thing called key table. Maybe you need to press a button to make the webcam work?

Re: [SOLVED] Webcam Not Detected At All (Lenovo X220 Tablet)

lsinput was useless, but I'll post the output anyway, cause who knows who it might help someday. Hey, thanks for all the help by the way.

Anything else I should try in Ubuntu before I boot back to Arch?

Re: [SOLVED] Webcam Not Detected At All (Lenovo X220 Tablet)

The output is not exactly useless - it gives the names of respective devices. Sadly, there seem to be some events missing.

I'm out of ideas for now, sorry.

Re: [SOLVED] Webcam Not Detected At All (Lenovo X220 Tablet)

Okay, thanks anyway. To any other knights and damsels of the Internet, that thinkwiki link did tell me a little more. First, Fn+F6 is the XF86Webcam button, and second, /dev/input/event5 (which I have) is supposed to be the webcam.

1. Fn+F6 did nothing, which isn't surprising since there's no device for the keycode [212] to talk to, and besides, I haven't told my window manager to map any command to keycode 212.
2. /dev/input/event5, in Ubuntu, was the touchpad, so who the hell knows?

Re: [SOLVED] Webcam Not Detected At All (Lenovo X220 Tablet)

One user with a similar problem got his camera working this way: http://ubuntuforums.org/showthread.php?p=11030635
Yeah, I know this post is about system76 computer and not a Lenovo one, but at this point it's really the last thing I can think of.

Have you tried other Fn-F# combinations?

Re: [SOLVED] Webcam Not Detected At All (Lenovo X220 Tablet)

In a horrible twist of events, I realized that the webcam that I thought wasn't being detected was actually a plastic placeholder. I called Lenovo and, sure enough, the system was configured without a webcam.

Which sucks, because I could swear I had chosen a webcam..........

On the bright side, I'll get a relatively cheap webcam that can clip to my monitor and is known to play nicely with Linux, and it'll never matter again.

Thanks for all your help; I'm marking this solved.

I just died laughing.
Twice :-)


All's well that ends well, I guess.
