Ubuntu Multimedia :: Webcam Only Works For Default User?
Feb 1, 2010
On a PC with 4 users (Karmic), I have installed a webcam. Everything (cam and mic) works for the default user. Cam works in cheese. For the 3 other users, there only are a "testpicture" in cheese and no mic . ???
just installed ubuntu 10.04 a week back.It updated as well through the update manager.Then I installed latest version(beta) of skype from the .deb downloaded from their website.In the beginning my webcam was detected but the video used to flicker.So I searched the net for a solution.I tried launching skype using 'LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype' command but there was hardly any difference.Then I came across gstreamer properties.I tried the three options and there started the problem.Now my webcam is detected only on its first launch.Once i stop the test there appears a black screen.I uninstalled and reinstalled skype but in vain.I tested it using cheese and vlc as well.
By using the preload command D_PRELOAD=/usr/lib/libv4l/v4l2convert.so skype I got my Labtec Webcam 6 to work in cheese and in skpe (although with a number of errors coming up in the terminal - see another post of mine) in ubuntu 10.04. I now updated to ubuntu 10.10 and now I do not get any errors but not any picture either. It just remains black regardless of whether I do the preload or not.
I'm running Ubuntu 10.10 on both my laptop and desktop. I've gotten a Gigaware Webcam with Mic (Radio Shack) 25-157 camera to work out of the box on my Del E-1505, no problems. Even interfaces with Skype correctly.
On my desktop, though, the camera light comes on, the camera is recognized through lsusb:
Code: Bus 005 Device 003: ID 093a:2620 Pixart Imaging, Inc. and /dev/video0 exists, but I can't access it through VLC or Skype.
My webcam works at my end but two people have said they can't see me their end using skype. They webcam with other people so i know it is not their settings or anything. One has a mac and the other a windows machine. I really don't have anyone else to test this with as most people i know don't have webcams.
I'm using a basically vanilla Lubuntu 11.04 My Logitech E 3500 webcam works fine with Cheese. I have just installed Skype, but my voice isn't picked up on the test call, and no video either (the webcam light remains off). I've tried logging off and into Skype.
I'm having here annoying "problem" with my webcamera. Everytime I want to use it as a microphone it needs to be switched manually in sound settings menu. It's not a big deal but I would really rather let it be switched automatically like plug and play or something like that.
I cannot find a post that matches this scenario...the id created during the install (from CD) of Karmic has fully usable sound. However, users created from the Users and Groups app do not.
I have made sure that all users are defined to the audio, pulse, pulse-audio, and pulse-rt groups. No luck.
I have followed every step I have read having to do with the alsamixer. No luck.
I have verified that alsa and linux itself are at the latest versions.
i have sony viao vgn-fz11 Can someone please help ,im new user to ubuntu been trying to get webcam working properly at the moment its upside down and does not work in skype at all just get black screen does this look correct? do i have the right driver?i will try and give as much information as i can.
I have a problem making work a webcam. At the begining, after the instalation of 10.04 in a new laptop, the webcam did not work but with a lsusb I see that the webcam was Webcam 5986:0241 acer. I was not able to config neither use the webcam with any application. After lots of test and forums reading I could not do my webcam to work, and now when I do a lsusb my webcam does not appear.
From time to time I have seen messages asking if their new device works on Ubuntu. This is to advise that I recently purchased a "Smart Webcam" brand inexpensive webcam at a local U.S. building products chain. Strange place to find such a thing but it was very low priced so I thought "why not give it a try". As it turned out, it works with my 10.04 install. Shows up ok on Ekiga and in gstreamer-properties in terminal. The video image quality is not as good as some but is suitable for casual use.
The microphone is brought out via a "Y" off the USB cable and ends in a 1/8" audio plug that will plug into a sound input port. I have not tried the mic but it should work. There is almost no documentation provided. Lastly, I have no connection with either the manufacture or the store. Just thought someone might be considering one of these and wondering it would work in Ubuntu. It does for me.
I am running Maverick 10.10, kernel 2.6.35-22 (32 bit) on an HP DV2000 with Skype version 2.1.0.81The webcam is detected by lsusb as Bus 001 Device 002: ID 0c45:62c0 Microdia Sonix USB 2.0 CameraI have tried some of the normal fixes found on many other threads (and HERE), including running the following commands from the terminal:
I have used my webcam with skype before in several ocations, but now im not able to do so.The wencam works with cheese, so i dont now where to got form here.On skype video options, it shows only one video/webcam device (CNF7017 (/dev/video0). when i with test on the options shows a gray screen, which is the same that im sending to my contacts when we video chat.
i have a life tec webcam which automatically installed by ubuntu 10.10 and working except the led of the cam is always off how to make the webcam led work?
I can SSH to my own box using "ssh -X arancaytar@localhost" and run graphical applications. When I try the same using "ssh -X chris@localhost", I get an error message saying
Code: chris@enki:~$ gedit X11 connection rejected because of wrong authentication.
I have the following webcam : Microsoft Corp. LifeCam VX-1000.
Code: ben@vegas:~> lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
[Code].....
So 11.2 obviously supports that webcam somehow, since it works on my desktop. Looks to me like something simple should make it work on the laptop as well, but I have no idea what...
accidently deleated ubuntu lucid default theme,and lost the default user logon,it's now flat and gray.how to get it back?i still have the background, not the user logon
Choising an hardware in LINUX is not easy since one has to check before whether it is supported. A large hardware base is supported , but not everything.
Which webcam is sponsored by DEBIAN TESTING that works surely with just a plug and play (skype / camorama...) ?
My logitech quickcam express works fine with gstreamer-properties and cheese, but i need to take webcam pics from console. It worked before the latest upgrade to squeeze, then:
My kernel is kernel 2.6.32-5-686
I don't know what to do... i'd like to run another kernel but i don't know which one..(and how to do that, i'm on remote)
I was impressed with the hardware detection in Fedora -- it picked up my wireless & webcam right out of the box. The odd thing is, that Fedora picked up the webcam right away, and it worked perfectly in Cheese (I was able to take both photos & video), but when I try to use it in Skype all I get is green "snow". The webcam is a Logitech QuickCam Communicate STX.
I'm using Ubuntu 9.10, and a usb webcam that is shown as 'Bus 001 Device 005: ID 0ac8:3450 Z-Star Microelectronics Corp.' by lsusb.
The problem is that on connecting the cam, it just works with the first program I start (skype, tokbox, messenger), and if I disconnect it or switch to another program, it stops to work and I have to restart my computer to make it work again.
Is there some good solution to reset the camera without rebooting to make it work again?
I'm running Kubuntu Karmic Koala 9.10. I just got a no-name USB webcam. It works fine under Windows. Under Linux the behavior is odd and a little frustrating. xsane does recognize it, but when I attempt to preview it or scan, I get the message "Failed to start scanner; invalid argument". Under skanlite, I can scan an image but if I attempt a preview, skanlite generates an internal error. The USB code is... Unlike the other USB devices, no name shows up.
I'd like to use this device under Skype, but the Linux version of Skype doesn't provide any way to test whether the device works or not. Windows does provide such a test (via Welcome), and the webcam works correctly there.
I want to add 50 new users, not on the server yet I want to add them all to group Accounting - with 1 option, not user by user I want to setup a default password for them all, and have it say something like 'You must now change password or no access will be permitted' Any other options I also want to do once, not for each user?
I installed freenx on my desktop and decided to set up a custom key following this tutorial: [URL]
Code: sudo dpkg-reconfigure freenx-server
Here I chose 'Create new custom keys' and SSH. After copying the client.id_dsa.key file to my laptop, I was able to log in no problem. However, I decided to check and used another computer (running qtnx as a client) to attempt a login with the default key.
It still worked.
Have I missed something in the fine print here? If not, is there a way to fix this behavior?
Using webcam component of XawTV package as supplied with Ubuntu 10.10. My implementation seems pretty basic, just needs to snap every 5 seconds and ftp to web site. It actually works just fine, but only for an hour or so. Then process continues to run, but image does not update. Kill & restart webcam and it works fine again, until it doesn't. Video stream in XawTV window is fine throughout, so I don't think there's a hardware problem.
