Quickcam Messenger, output is black

Hi guys,
I installed Arch Linux (2.6.28-ARCH) yesterday, together with KDE 4.2. I knew the driver I need for my webcam is built into the kernel, but it does not output anything (black). I am in the video group, and the drivers are loaded. When I try to test my webcam in Kopete, the image turns black, but the LED on my camera is lit.
Does anyone have a solution for this?
Thanks in advance
EDIT:
I have just tried aMSN, and the webcam works (V4L2). What can be the cause of the problem that it's not working in Kopete?

Hi,
how did you get the webcam to work?
I just got the same cam from a friend because I need it to test something for a small university project but i cannot get any application to work with that camera.
dmesg says:

(Sorry for "hijacking" this thread, but it seems mostly solved and Davey might have a hint on what to ;-) )

USB device (Logitech QuickCam Messenger) stopped working (SOLVED)

Hey there,
I have a logitech quickcam messenger, which used to work perfectly 2 days ago. I updated my system yesterday and this morning, but I tried the cam again only now, and neither cheese nor webcamstudio work anymore (it never worked in skype since I moved from Mint to Arch a few weeks ago, but that was easily (and better) addressed by starting cheese and then using desktop sharing in Skype)

The (not so obvious) solution was to connect the webcam directly to the computer and not through a USB hub. I have no idea why it used to work and suddenly stopped, but it works again now.
sorry to take up your time, in case I did.

Logitech Quickcam Messenger no dice

So I have this logitech quickcam messenger, and suprise, its not working.
Anyway, i plug it in (USB), and several modules load, /dev/video0 is created, but other than that, no functionality.
Mostly when i try to run any video app I get (running motion):
[1] Failed to open video device /dev/video0: Device or resource busy
I can run cat /dev/video0 and get a lot of output streaming out, so thats a good sign. But I wonder is the device really busy or is the driver screwed up?
I'm using the quickcam_messenger module that autoloads when i plug it in.
I've also tried qcmessenger and gspca_zc3xx modules to no avail.

Old topic, but case is up to date.
I was struggling with my own older Logitech camera Quickcam Pro. Apparently I bought the wrong one, but finally I set it up with limited functionality.
Of course the problem was the driver. No pwc, no linux-uvc and not even spca5xx. I had to compile new driver module with nw802. Actually mine was nw801, but I just had to edit one file before compilation, apply some patches, insert this module and now it works.
Please do some researches and specify correct driver for your webcam using ProductID. Logitech webcams have varied set of drivers. :-)

Video output only black & white

The video output on my Macbook Pro is now only black and white; last week it was fine (in full color). Any ideas?

Thanks, but that's not the problem. The main screen on the Macbook is fine, but the video output is black and white. So, for example, when mirroring the screen, I get a color version on the Macbook, and a black and white version on the TV (and it's not a problem with the TV).
Any other suggestions or ideas?

I was following the webcam page - http://wiki.archlinux.org/index.php/Web … our_webcam
The guessing came when that didn't work
In any event, that raises a new issue

Logitech Quickcam Messenger [046d:08f0]

I was extremely surprised when the kernel gave me the illusion of plug and play, using the gspca driver for this device.
Unfortunately the gspca driver only supports the 046d:08da cam with the same name.
It looks like the actual driver to be used is the one at http://mag.cx/messenger/ , which is prepackaged in community under the name qc-usb-messenger.
Unfortunately, despite seemingly detecting everything...

Lenovo Ideapad U410 - no screen output or black screen, and just out of warranty

My kid has been using this laptop and loved it, but mentioned a while ago it was difficult to power it back on after turnned it off. However she managed to work around by putting it in hibernate/sleeping mode only, or recycling the system many times (by holding on power button to force it off). The issue was black screen (no Lenovo logo) but computer was on. I didn't pay much attention because she can still make it work, and I was too busy. Last week, there was a windows update (again) and the computer was forced recycle. It never comes back alive again. The same, computer is humming, but no any visual output on screen, just black. Tried novo button, bootable USB, external monitor, all no use. Check the warranty, just over by 2 months! Asked the service store, to fix will cost at least $200-$300 to replace the motherboard! It does not make sense when spent a bit more could buy a new notebook. But my kid liked it and it does not make sense to throw it away either, when it still looks pretty new and only being used very lightly (schoolwork only). It is sad, especially the brand has been gainning my trust. I probably don't expect a "good" solution either from Lenovo or community, but just throw my frustration here (only because have just registered the account and there is no support email or web form). If Lenovo want to make customer happy, the part shouldn't be so expensive for a short-lived laptop! Just by the way, there are many posts about Ideapad's black screen issue, and many blameed window 8.1 for the compatibility problem. It made me thought so too because the initial sympton was exactly the same. The best thing you should do: don't waste time on fixing the driver or config, get the hardware replaced as soon as you could when still in warranty. If not so lucky, probably think it twice next time when you want to buy a Lenovo.

Welcome to the Lenovo Community !
Sorry to hear of all the problems. Here are a couple of things to try........
First, try a reset of the BIOS. The procedure can be useful in resolving some hardware conflicts which your computer may have. Just do this......
1. Unplug the charger / adapter.
2. Press and hold the Power Button for 15 seconds.
3. Plug in the charger / adapter if needed and power up the system to see if the problem was resolved.
If you are comfortable working inside your laptop. try this........
Try the reset again with the battery removed.
If the reset didn't resolve the problem then you may have a failed piece of hardware preventing the bootup. Remove the battery, hard drive, optical drive, memory, wireless card and bluetooth if it is installed. Now try to power up the stripped laptop. With all the hardware removed you should have lights come on and it may possibly beep since there is no memory installed. If the laptop is showing signs of life start adding hardware one piece at a time starting with a memory module and boot up the laptop. If it doesn't power up try the memory in the other slot. Also try the other memory module separately in both slots if two are available. If it is still showing signs of life add another piece and boot. Do this for each item until it doesn't power up again. The last piece of hardware installed is your problem part.
The link below is for your model's Hardware Maintenance Manual. The manual will explain how to remove the various hardware items. When working inside your system please follow all precautions and recommendations that are noted in the manual.
http://download.lenovo.com/consumer/mobiles_pub/ideapad_u310_u410_hmm_1st_edition_mar_2012_english.pdf
There is also a Lenovo Training video that will show you how to remove the various items. These are listed in the FRU section.

80GB ipod only outputs in black and white

I just bought a new 80GB 5th Gen iPod and hooked it up to my TV and it only outputs the picture in Black and White. If I take my old 60GB 5th Gen iPod it will output a picture no problem in color with the same TV and the same cable hooked up the same way.
All TV out settings are the same:
TV Out: Ask (I turn to ON)
NTSC
Widescreen On
Cable: Apple's iPod AV Cable M9765G/A
The weird thing though is if I take my new 80GB 5th Gen iPod and hook it up to my "MyVu" headsup display, it displays in color. It just won't do it on my TV.
Why won't it display color on my TV?

Try a different Video file on the 80 GB;to see if any changes? Are there any other title;s Videos are Podcast,
TV Shows that will playback in color-- if so It's possible that your file format is not compatible.
Check to see how the video files are define by format, frame rate etc; that your using as a reference to playback on TV.
See if you have any other Video's on the 80GB that will play in color.
Make sure your 80GB is using Itunes Version 7.0 or higher

Converting Word files to pdf- Output is black and white

Hello -
I recently updated the Adobe 9.0 Reader on my computer and now when I try to convert a Word file with pictures and/or difffent colors of fonts to a pdf the output is ALL black and white. I've seen some people here on the forum saying their printer caused the problem, but I have not changed printers and this same Xerox printer worked before. Plus, I am not even printing the files yet - just looking at them in Adobe Reader - and they are in black and white. This never happened before.
Any ideas? Need help!

You may want to ask in the forum for Reader.

It doesn't matter what size your clip is. The video output is 720x480. If you place the small cip inside a standard video player, it will expand because the video player has to fill the output. Umm, that's not EXACTLY what's going on. The video feed cannot distinguish between big and little clips. it only knows to fill the screen with whatever it sees.

Logitech quickcam pro for notebook (black)

Does anybody know if logitech quickcam pro for notebooks work in mac osx 10.4.4?

Mark offers the succinct version. I, on the other hand..... What a long answer I am going to give to such a simple question!
As explained in iSight versus DV Camcorder or other web-cam, the answer to your question really depends upon the software you will use to drive the LOgitech QuickCam® for Notebooks Pro.
Your Mac can use webcams for many different applications. To be certain of success, check the system requirements and list of supported cameras for the application(s?) you intend to use. If you still have questions, contact the application software developer and ask him directly.
For instance, if you plan to use your webcam with iChat AV for video chat, you will see that Apple's Mac OS X 10.4: iChat AV system requirements call for a FireWire-based camera for video chat. However, a third party add-on called iChatUSBCam can allow the use of many USB cameras with iChat.
QuickCam® for Notebooks Pro is listed as one of those supported cameras on iChatUSBCam's camera guidepage, provided you use an additional Driver available from one of the two sources linked there.
If you have difficulty finding info about some other application, try searching Logitech's Product Support site for your camera choice and the Search Text "Mac" (without the quotation marks).
The search at Logitech's Product Support may answer your question. For instance, I checked for iPhoto compatibility and found this Answer:"Only the Logitech Pocket Digital 130 will work with iPhoto. This is because the Pocket Digital 130 actually acts as a storage drive with images saved on it. Our other web cameras do not function like that. They stream the images through the camera but they don't store them.
"To work around this, simply take a picture with your web camera and use our Quickcam software to save the picture to your system. You can then open the file in iPhoto and edit or use any other features to change the file."If you are still having difficulty, you can search Logitech's Product Support FAQs or their Knowledgebase, visit Logitech's own dedicated User Discussion Forums, or even email your question directly to Logitech for an official answer.

Using Logitech QuickCam Messenger with Tiger/Classic 9...

I just received this webcam from my daughter and found on installing the disk that it will only work with OS9....I have the Classic 9 installed on this Powerbook, but is this the same as OS9...as when I try to intall it in the Applications OS9 it will not proceed...is there another way to do this ?

What sig says is good. However, sometimes Classic is not the same as being booted natively to OS9, which your computer is incapable of doing. I don't know about this camera but true OS9 items sometimes need access to the computer hardware and basic resources on a fundamental level. In Classic it is really OSX that is running the system and the interface to the basic features is not the same as when OS9 is running the show.
Are you running the installer from inside Classic? If not, that might be a problem. Otherwise it is possible the installer is doing a check for which operating system is running the computer and finding it is not OS9. Workarounds might depend upon the sophistication of the installer. Sometimes an installer just copies files out of a folder and puts them where they belong. In that case you could just copy them out yourself. On the other end of the scale it may be a compressed archive package installer, in which case if you wish to experiment further you would have to find an OS9 computer, install on there, then copy the components out and copy them into the correct places on your OSX machine.

Quickcam Messenger Build-In Micro [solved]

Hello together,
I have a problem with my webcam. Since the kernel-2.6.20 i can't use the internal microphone of my webcam. I run another machine with Ubuntu 7.04 and i have the same problem. It seems that that they changed something with USB-Audio-Devices in 2.6.20, because on my Ubuntu-machine my USB-Soundcard didn't work anymore (with Arch and 2.6.20 - no problem). I hope someone can help me.
Thanks, stonerl
P.S. Sorry for my bad English.

First off let me say upfront that I'm reasonablly technical and have done all the troubleshooting steps on this site (resetting box, changing resolutions...), as well as swapping out cables, and moving the X1 connection to one of the other inputs. Also I can confirm I can get color signal to all HDMI inputs on the TV in question. Is this just a box issue, or has someone else had this happen and has steps to fix. Hoping it's just a setting that somehow got flipped. If possible would like to fix vs. just getting another box as family will be a pain after loosing their shows and movies on DVR. You might try hooking up the coax 'out to TV' to the TV's coax connector and changing input to that coax. Is there color then?

Rusty,
What would that accomplish? The OP is going to want (and is paying for) an HD connection so why would that test even matter? Besides RF and HDMI are entirely different signal paths through the box so your suggested test ultimately proves nothing.
