Web cam won't work in Intrepid, worked in previous Ubuntu versions

[Craig Gilding]

Well I actually posted here https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/41779 but someone asked me to file a new bug report so... I'm doing that now...

Information below;
My web cam worked fine on previous versions of Ubuntu. However, it won't work on 8.10 for some reason. Here is the camera in "lsusb"

Bus 003 Device 005: ID 05a9:a511 OmniVision Technologies, Inc. OV511+ WebCam

Attached is my output for dmesg and my /var/log/syslog

If anymore information is needed please feel free to let me know. I am on most nights so I will keep an eye out :D

Hello,
can you try :
ls /dev | grep video and
mplayer /dev/video?

What software do you use ? (cheese?)
Thanks.

[Craig Gilding (slasherx2)]

ls /dev | grep video gives;

video0

mplayer /dev/video gives;

Yes, I use Cheese, although, I tried to setup my web cam with kopete and amsn but they wouldn't have it.

[François Blondel (francoisblondel)]

Ok, thanks
So the drivers are installed.

try : mplayer /dev/video0 (the number of the device)
try : gstreamer-properties

I don't know more.
Thanks

I've tried that last command before and got the same thing

[François Blondel (francoisblondel)]

ok, thanks.
I don't known more about. :(

[Craig Gilding (slasherx2)]

Never mind, hopefully the information I provided will help someone else fix it. If anymore info is needed, let me know.

[Marc Sanfaçon (ubuntu-jafs)]

Just to let you know that I have the exact same problem as Craig. I have the same WebCam, at least the same USB name. Running the commands give me the exact same output.

I never tried it in previous Ubuntu version. I am running 8.10, kernel 2.6.27-9-generic.

Marc

[Craig Gilding (slasherx2)]

Just a note, I tried this cam again with cheese on the Ubuntu 8.04 live CD and it worked no problem so it must be something that was changed in 8.10

[Connor Imes (ckimes)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it without more information.

Please include the information requested at https://wiki.ubuntu.com/DebuggingHardwareDetection as separate attachments (I see you've already attached some, please attach the full lsusb per those directions).

I'm going to close this task against the old kernel and leave it open against the development kernel.

Thanks in advance.

[Marc Sanfaçon (ubuntu-jafs)]

Find the requested information attached.

[Connor Imes (ckimes)]

Thank you Marc. I'm marking this bug as Triaged, but it would also be good if Craig could also attach the requested information since he is the original reporter.
Thanks guys.

[Craig Gilding (slasherx2)]

I will add the requested info on Monday when I get access to my laptop, sorry for the delay

[pixolex (pixolex)]

I have the exactly same problem and i'm leaving my logs here. I hope it helps.

[Craig Gilding (slasherx2)]

Sorry for the delay, attaching the log files now...

[pixolex (pixolex)]

Tested the webcam in Jaunty Beta 1 and still doesn't work.

[palimmo (palimmo)]

Same problem with Jaunty

[Sergio Zanchetta (primes2h)]

== Regression details ==
Discovered in version: Intrepid, Jaunty
Last known good version: Hardy

[Jeremy Kerr (jk-ozlabs)]

Looks like the video device is present, but you don't have permission to open it. Could you paste the output of:

id
ls -l /dev/video0

Cheers,

Jeremy

[pixolex (pixolex)]

Sorry for the late response Jeremy.

crw-rw---- 1 root video 81, 0 2009-09-22 22:07 /dev/video0

[Jeremy Kerr (jk-ozlabs)]

pixolex: how about the output of 'id'? are you in the 'video' group?

Cheers,

Jeremy

[pixolex (pixolex)]

uid=1000(pixolex) gid=1000(pixolex) grupos=4(adm),20(dialout),24(cdrom),44(video),46(plugdev),108(lpadmin),123(admin),124(sambashare),1000(pixolex)

The device is detected like this:
ov511:USB OV511+video device found
ov511:model:Creative Labs WebCam 3
ov511: Sensor is an OV7620

[Jeremy Kerr (jk-ozlabs)]

picolex: looks like you do have permissions to access the device. Are you seeing the exact same output as Craig Gilding (from comment #6) when you run gstreamer-properties?

Craig: could you post your output from 'id' and 'ls -l /dev/video0' too?

[Craig Gilding (slasherx2)]

Quick note to let you know I'm still alive..
I'm currently at work and my laptop is upgrading to the new alpha. I'll dig the cam out when I get home and post you the results. Apologies for the delay.

However, sudo gstreamer-properties work and sudo cheese too.

[Jeremy Kerr (jk-ozlabs)]

Craig - any updates?

[Craig Gilding (slasherx2)]

Indeed, I forgot this was still open - sorry, Have just tested it on the newest Ubuntu (10.04) and it seems to be working as expected :)

Thanks for your help and thanks to everyone who worked on the bugs and got them fixed :)

[Sergio Zanchetta (primes2h)]

I mark it as Fixed due to the last comment.
