Ubuntu Multimedia :: Reset Webcam (Phillips SPC 900 NC) Without Loading Windows Xp
Jul 14, 2010
My webcam works AWESOME when it works. However, occasionally it produces no video for Ubuntu based applications. Cheese, aMSN, Skype or anything else for Ubuntu Lucid.
I have tried power off & cold booting. Moving from one USB port to another, warm booting etc...
The only way to make it work instantly is to boot into Windows XP and access the Webcam. Then upon rebooting to Ubuntu the cam works perfectly again.
It's not a matter of Ubuntu finding and recognizing the cam. It always does and TRYS to activate the cam (the led comes on when loading any cam application) but it produces no video.
Is there a command I can use to force a RESET of the video device so I can stop loading Windows?

Why do I keep getting this error when I try to search something on google. It happens when my query has around five or more words. If a search for just one or two words I don't get the error. I know it's not google because it happens with bing, msn, and yahoo too. The connection was reset The connection to the server was reset while the page was loading.

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 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.

Well, after searching several forums and trial and error, I finally got my builtin webcam to work. Its r5u870 05ca:1836. The only problem I now have is that after a hard boot (system was powered down), I then have to do a soft boot for this to work properly. It seems to me that the problem is the firmware loading. Obviously, doing a shutdown -r means that the firmware remains in the webcam device and then everything seems OK.
After a soft boot:
linus:~/bin # lsmod|grep -e sony -e uvc -e r5u
r5u870 26436 0
usbcam 47808 1 r5u870
sony_laptop 35688 0
uvcvideo 66124 0
rfkill 22772 2 cfg80211,sony_laptop
videodev 39168 2 usbcam,uvcvideo
v4l1_compat 16004 2 uvcvideo,videodev
linus:~/bin # lsusb|grep Ric
Bus 001 Device 004: ID 05ca:1836 Ricoh Co., Ltd Visual Communication Camera VGP-VCC4 [R5U870]
linus:~/bin # luvcview -L
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
/dev/video0 does not support read i/o .....
After a hard boot, luvcview will not display anything after the line beginning with
{ pixel...
How to make this all work without the soft reboot?

OK I feel silly having to as this as it probably some setting I changed but cant figure out where I did it..
So when I click on the minimise button of an open window instead of dropping to the bottom panel it disapears completely. Likewise if I have say a folder open and then open something new the new one replaces the old one instead of al being available in the panel.
Where do I reset this?

every now and then, one of my customers forgets his windows user password, and asks me to reset it. till now i used a small windows app called "Password Renew for NT" from a windows PE bootdisk, but i want to have an alternative that runs on my opensuse 11.4 box, so i can connect the windows hard drive on it and reset the password from suse.
I found and the program "chntpw" in the build service, but it seems on beta status. And most information i found of it is very outdated. Has anyone used it? does it work ok on all modern windows versions (xp, vista and 7)? any other alternatives you can recomend?

I'm unable to reset using either the reset option in gnome shell or the command using a terminal. When I select it the shell exits and displays the graphic "exploding" and then it just sits there. Shutdown works fine; just no reset. Any ideas? I've installed from the DVD. I booted the live CD and it resets just fine so I know it's no my hardware

I have a netbook with an intergrated webcam running Ubuntu Karmic 9.10 I'm looking for a way to share the camera to a windows desktop computer to use the webcam as if I had plugged in a USB webcam. I want to do this because Windows has some really great software for Webcams but runs horribly on the netbook.

I am using mplayer with vdpau enabled in Ubuntu 10.10. It works very well in general, reducing cpu usage for hd from 50% to 60% to around 10 -15% or less. There is however one slightly annoying problem. It is that mplayer would appear to "forget" its vdpau output setting once in a while and especially after rebooting. When that happens it needs to be "reset" in order to use vdpau. "Resetting" basically just means opening gnome-mplayer and change video output to xv and then back to vdpau again.
I should clarify that the setting has not actually been lost, it still says "vdpau", it just need resetting).

My screen resolution keeps reverting back to the default resolution 800x600. I'm using ubuntu 10.04, but had the same problem on 9.10 on my Acer Revo r3600 ION. I am able to change the resolution to 1280x1024 but have to do it by the nVidia configuration tool. The tool then allows me to 'Save to X Configuration'which it appears to have done successfully.See the sections from my 'etcx11xorg.conf' file. This is the state of the file after a reboot by the way.how I can get my desired resolution to persist after I reboot?
Section "Monitor"
# HorizSync source: edid, VertRefresh source: edid
Identifier "Monitor0"
VendorName "Unknown"
ModelName "Samsung SyncMaster"
HorizSync 30.0 - 81.0
VertRefresh 56.0 - 75.0
Option "DPMS"

I have hauppauge pvr-350 which has an mpeg2 decoder with an RGB and s-video out to let me send video to my tv. I'm using the ivtv drivers which work well. To test the card I ran
Code:
cat test.mpeg > /dev/video16
-bash: /dev/video16: Permission denied
So then I did
Code:
ls -l /dev/video16
crw-rw---- 1 root video 81, 5 2010-10-22 12:21 /dev/video16
sudo chmod a+rw /dev/video16
[sudo] password for patrick:
cat test.mpeg > /dev/video16
However the permissions get reset everytime I reboot. Is there any way to pass an argument to the ivtv driver to change the default permissions?

I am a recent convert to Ubuntu 10.10 from Vista. I work from home and do all of my work via remote login and video conferencing through Skype. In Vista, I could use my DV Camcorder as a webcam which, in turn, gave me video for Skype. In Vista, I used a program call "Tracker Cam" which I could run, and then it would act like a video driver for Skype and presto, I had perfect video in Skype.
Now that I am in Ubuntu, I am trying to achieve the same thing. I can hook up my DV Camcorder (A Sony Handycam HDR-HC5) and see the live video through Kino. However, this doesn't help me with Skype. I still can't enable video, or select a video device in Skype. I have Googled this up and down with no leads.
So, I am wondering if anyone has done this with Skype (or other programs) to get their DV Camcorders acting like webcams for video calls or is this just one of those things that won't work in Ubuntu?

I use to have vista and ubuntu on my PC. Yesterday accidentally I created a new partition "table" the point is that I erased all my partitions on "MyDisk". After a while I decided to re-install ubuntu ( 9.10 karmic koala ) and take advantage of the situation and upgrade to Windows7. Since I already had the ubuntu cd, I installed it first, then downloaded the Win7 cd to install it. The problem is that Windows7 installer doesn't load.
All I get is:
<<BLACK SCREEN>>
Grub loading.
<<BLACK SCREEN>>
underscore
Ubuntu logo
ubuntu login
So I don't know whats wrong. Right now my disk looks like this:
MyDisk >
MyDisk1 ntfs ( For windows 7 )
MyDisk2 > extended (using linux with 2 more partitions: ext4 and linux-swap)

I've recently installed Ubuntu 10.04 it installed and chain-loaded correctly however I installed it on partition that was too small so I used gParted to copy the files 1:1 to a freed up partition.The result was it copied fine but the Grub file became messed up.
I had to manually reinstall Grub2 from the LiveCD and the Linux was starting up fine, however now I'm unable to boot to Windows.Is there an easy way to reinstall/re-chain the Windows bootloader so its able to chain-load from Grub.

After a recent Debian 8 update, I notice a new problem with the Gnome-Terminal. When you open a new tab or window, whatever is the cwd of the current tab becomes the cwd of the new tab or window. This always used to reset to ~, which is what I want. Is this a new "feature" and if I can disable it?

Starting around two weeks ago, Iceweasel began closing at unpredictable intervals for no apparent reason. When I ran it in GDB, it came up as a segfault, though the backtraces were different each time. It would even do this in safe mode, though it generally took longer. Icedove began doing the same thing around the same time.
So, I decided to reset my profile and start over. But now it's still segfaulting, even in safe mode.
A cursory use of memtester didn't turn up anything unusual.
Could it be some browser addon that is causing problems even when it's not activated?
If so, why is Icedove doing the same thing occasionally?
The biggest problem is that it's intermittent, so I would have to use my browser with a new profile for a long time before I could confirm that the problem is actually fixed.

purchased a webcam to record videos with in Ubuntu. I plugged it into the USB slot (and audio into the mic hole) and it seems to work ok. But I'd like to record a video from it and save it to a file. How can this be done?I tried Cheese and no audio was recorded.I tried GUVCView and it was fine except for slow video & audio delay.I can't find any other programs for recording webcams on Linux.
