Fedora :: Resolve An Ongoing Fight Involving /dev/video Node Assignment Between 2 TV Tuner Cards And USB Video Camera
Feb 27, 2011
I am trying to resolve an ongoing fight involving /dev/video node assignment between 2 TV Tuner cards and a USB video camera.
Each time I reboot the three devices seem to shuffle their /dev/video assignment. i.e. what was /dev/video0 (USB camera) after a reboot magically becomes /dev/video1.
This causes all kinds of grief between my MythBackend and ZoneMinder who expect the devices to have static assignments.
how to best solve this? I did a brief search and one solution appears to be to statically assign the devices.
I'm using 9.10 on acer aspire one (not the netbook remix).im using the default messanger client empathy.everything else works fine but when i try to video chat the video chat begins but if the other person even moves a litte or even nods his head then the video becomes so choppy that u cant see anything and then after 5 min comes back to normal for a second or two.i have all the latest updates and gstreamer0.10-ugly-multiverse which is required for video chat b/w empathy and gtalk.
Due to the miss of proprietary drivers from AMD for Fedora 12, I have installed a second video card in my system (a Nvidia one) for BOINC calculation. This card is not connected to a monitor.
So in the system I have this two cards: ATI Shappire Radeon HD2600XT (256MB) Asus Nvidia Geoforce 6600 (356MB)
The ATI is in the first PCI express device, the Nvidia to the second PCI express:
Code:
So I have used this Xorg configuration file (if I let Xorg to configure without the configuration file, it sets NVidia to default card and X files to start):
Code:
The Nvidia driver were installed as described in some forum:
1) disabling nouveau in grub configuration
Code:
2) Take SElinux to alow the driver:
Quote:
With this, the driver is correctly loaded in memory:
Code:
But the Xorg says that not Nvidia Driver where found (see the attack file).
I am a bit overwhelmed with all the information out here, and can't get this to work properly after trying to for two days. I have a PCI ATI card(Sapphire Radeon 9250):
I have onboard video card (GeForce 6150SE nForce 430) and I install one PCI-E video card (GeForce 7300 GT). In BIOS I set primary video cart to onboard. Is it possible to work simultaneously? lspci -v command showing both, but nvida-setting, nvidia-xconfig and system-config-display only show one, never both.
I am trying to put together a list of nvidia cards with the aim to include the nvidia driver for listed cards in autoplus etc..so what id like is the output oflspci -nn |grep VGA Quote:eg:02:00.0 VGA compatible controller [0300]: nVidia Corporation G86 [GeForce 8500 GT] [10de:0421] (rev a1)Please could you post them here http://dnmouse.org/support/ you dont need/have to put your real name and email anything will do
I have a printer that is not getting a device node assigned at boot.The printer is attached with a USB to Parallel (IEEE-1284) adapter cable.When I plug in the usb cable when the machine is running, the printer is assigned the device node: /dev/usb/lp0
I am guessing that during startup, the printer device is not detected since it is plugged in over an adapter cable which may be considered a device in itself?This is for a retail store, and we rely on the printer to pop the cash drawer open, so it kinda has to work without a "secret handshake".Unfortunately our workstations do not have Parallel ports. I would be happy to share terminal output, udev info, I'll write you a poem but I could sure use a helping hand- I'm stumped!
I have a Phillips SAA7130 TV Tunner card and seems to have installed correctly. I have Xaw TV program on Ubuntu 10.10. I am unable to get the Video. I tried 3 players and in none I am able to see the video. The source in all programs says 'Default' and am unable to choose the card as source. I am also ok to allow remote login to check.
I am looking into buying a better graphics card, most likely Nvidia, for my HP D330 DT.How do you tell if the graphics card is compatible with your machine?One more thing, is there a way to tell if my GPU is an, AGP, PCI, or PCI express without opening my computer??
I am a new user to opensuse, coming from ubuntu. I have a usb to vga external video card that allows me to plug in an external monitor to a usb port.Tritton SEE2 UV150 Looking around there is a deb file available for ubuntu and the sources are on the suse build service. Though it does not say its available for suse. So im wondering if anyone else has used one of these devices and/or knows how I can get it to work. The pages i have found related are here:
I have 2 video cards installed, and I only have one 22" monitor (1680x1050 pixels).ATI Radeon HD 4290 Nvidia 7300 GT Silent How can I make the both video cards render OpenGL stuff at the same time? Is it even possible?
I have recently decided to use ATI video cards again due to poor linux support several years ago. I currently have a Radeon HD 3000 series card however I have been unable to install the fglrx driver under Debian Lenny 64. It seems that the Catalyst 10.4 driver is not compatible with the Xorg version in Lenny.
So far the NVIDIA has been very good at making drivers available for the latest linux versions. I have been running Debian Sid with an NVIDIA card with relatively few problems.Is it still best to avoid ATI graphics cards or is this just a temporary problem?
My local priest has asked me if I can use my computer skills to stream church services live for people who can't make it to church.I said, sure thing! I thought it would be simple, but the deeper I look into it, the more lost I have become!Here's the tech requirements:
- A camera with good optical zoom and focused on the altar (the camera will be stationed at an unobtrusive point at the back of the church on the choir balcony) - Everything must be wireless (power is available on choir balcony to power the camera). - Sound should be synchronised perfectly with the video (have access to the church PA system - located behind altar) - the internet connection should be able to upload the stream to a virtual server (i.e. with root access) that's accessible to the web with ease. What upload speed would I need? Would 256k be enough? HD video is not required - ..... quality would be great. We can upgrade to HD at a later point in time! - What bandwidth requirement would my server need if say 1000 users were connected? Seeing as they would most likely be locals, would just one stream be sent to the local exchange and that exchange would send out the stream to the 1,000 users, or would each user have to have a dedicated connection to the server? - Say I bought a camcorder with HDMI output, what kind of processing power would I need to convert this to compressed video? (I've got an old Pentium 4 and an AMD64 2.0GHz lying idle in my bedroom and it would be great to make use of 'em instead of chucking 'em on the skip) - I'd like all this to be done so that HTML5 browsers can access the video, resorting to flash if necessary - I'd also like to be able to power down all the hardware with ease: i.e. set a timer. I'm sure ubuntu can do this with ease? What about configuring the camera to zoom in every time it is powered on? Can linux control the zoom on a camcorder? - Am I totally nuts?
I'm having problems configuring a second video card in Debian 7.4 on GNOME. I've tried running Xorg -configure but that errors. When I run xrandr that only seems to pick up 1 screen.
The current effect is that the second screen seems to fire up and display a debian logo, and I can move the mouse pointer on to it, but I can't place any windows on there. Also, every time I log out and log back in, GNOME creates an additional instance of the menus (I now have 3 "Applications" and 3 "Places"). It sort of suggests that it is trying to use multiple monitors, but getting it wrong.
I have 2 ATI cards that I used to use on windows to run 4 monitors. A recurring problem has been to get them detected in linux. Only my secondary card is picked up linux. When I manage the displays it detects the 2 monitors connected that card.
What are the specific steps I should take to get the second card detected? Supposedly there is a tool system-config-xfree. I don't have it, yum can't find it.
Also I heard it has something to do with editing some xorg.conf file or something to that effect. I have absolutely no idea how to find the "bus id" of my card, or lookup the horizontal refresh rates, etc..
I would probably have no problem following the documentation & editing the file if I knew a good way to find these values.
Someone also suggested installing linux twice and saving the xorg.conf it generates each time (with different card each time) and then merging the two by hand. That is like killing a fly with a hammer though, when I do this again and again in the future It'd be nice to not have to take twice as long.
In Ubuntu Lucid Lynx RC, I got NVidia's TwinView to work with 2 monitors in a single video card. But when I use the same monitors but split them between the video cards I can't make TwinView work and it starts a X server for each monitor. I want the same effect I had with one video card.
I was just wondering if is an easy way to configure three monitors run across two video cards (Nvidia Leadtek GTS250 PCI-E 2.0 1G 2DVI ) 2 on one, 1 on the other under the one xserver? I tried to get it going using the Nvidia driver package with no luck - 2 monitors seemed to be simple to configure using Twinview setting on a single xserver (my current settings) and I was hoping their may be a simple extension for three and if so is there an easy way to go about this? (I am new to Ubuntu).
I've been using linux for roughly 12 years now but I've always avoided linux on the desktop since touching X back in the day was quite a hassle. I recently decided that rather than keeping my windows desktop full of 15 PuTTY instances, I should rock the *nix desktop.
I started by installing Ubuntu 10.10 Desktop. It detected my two monitors handing off a pci express card just fine. I decided to install the ATI drivers when it prompted me - the proprietary drivers would let me select to use the monitors separately, but would always just default back to mirroring the screens. I was unable to get it to stop that, so I had to go back to the open source drivers. Which is fine, I don't really need the 3d accel. Roll forward a week, I ordered another video card to add another screen. I purchased another ATI card, since word on the street is that same-vendor chipsets play best together. This one had to be PCI, if this matters.
dmesg reports the new card is fine and happy, but the Monitors GUI thing doesn't detect any monitors off the new card, or report anything about it. So: what should I do to make the second video card get noticed?[URL]...
Been looking around and have been trying for 4 days to get my 3 monitors to work with my 2 video cards , When the system starts up I get the bootup screens on the 3rd monitor , then the login box shows up on the 1st monitor and when logging out I see the shutdown screen on the 3rd monitor again , so I know ubuntu see's it , but not sure how to include it in the regular desktop . It's just a lighted very dark red and I can't move my mouse or any windows over to it , here is my xorg.conf that I modified and tried to get it to work with :
# nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 260.19.06 (buildd@palmer) Mon Oct 4 16:01:38 UTC 2010 Section "ServerLayout" Identifier "Layout0"
I have this Asus UL30VT notebook, with two video cards, an Nvidia G210M (which apparently isn't supported by Nvidia for Linux, but I've read somewhere that it's possible to make it work) and an Intel card (I can't find the model name). On Windows, it is possible to switch between these two cards for battery saving reasons. Anyway, I don't really care about this on Linux. I would just like to make the Nvidia card work somehow.
One of my doubts is: how do I know if Linux is detecting both video cards?What I'd like to know is, how can I make sure whether Linux is correctly detecting the Nvidia card or not? Is lspci enough?And if we suppose that Linux is aware of the presence of the Nvidia card, how do I know which card it's using? Right now I can infer it's using the Intel card from the X log, but is there any other way (I don't know, any "/proc/..." files) to know?
I am going to purchase an IC-3030 camera. I want to access the video stream and download it as it happens, but not by using the Edimax-supplied video utility, as the computer will be running Linux. I am unable to find in the user manual whether I can access the stream directly or not. How can I access the video stream directly from an Edimax IC-3030 camera?
I use F-spot and Shotwell to extract photos AND videos that I made with my Canon EOS 500 or my Lumix.Actually the pics are extracted correcly but the videos are just consider as a pic and the pic is the first pic of the video.Is there any F-spot equivalent that extract everything from the camera?
I want to import raw High Def video into my computer so I can edit it on Cinelerra. Ubuntu doesn't allow you to use the ieee 1394 cable by default and everything I've tried to make it work, hasn't!!I don't want to go back to windows, pay a ton of money for some video editing software when there is an excellent video editing program already on my computer.]
I would like to know the best way to swap out video cards from ati to nvidia. For example. In windows, I would uninstall the driver, switch the cards, boot into a low VGA windows session and install the new drivers, reboot done.
In sues, I'm wondering if I uninstall the drivers, after rebooting I might loose my Gnome desktop. And I guess at that point I'd be looking at a blinking cursor?
I'm trying to get ubuntu working w/ 3 monitors. I have been given 2 video cards
lspci | grep VGA 20:01:00.0 VGA compatible controller: ATI Technologies Inc RV620 LE [Radeon HD 3450] 25:05:00.0 VGA compatible controller: nVidia Corporation NV44A [GeForce 6200] (rev a1)
I have had it working w/ two monitors plugged into the ATI correctly. and the nVidia monitor blank. Now I have the nVidia monitor working and one monitor from the ATI working, but I can't seem to get the last monitor to show anything. It does show the boot screen and works up until the point you are presented w/ the login screen for ubuntu, then it disappears and the nVidia monitor turns on. Might I have something wrong w/ my xorg.conf or do I need to do something more to get this to work? Currently I'm seeing this error in my Xorg.0.log file, but I'm not sure where to go from here:

I have a video card (Nvidia) in my computer that I want in another computer. I am going to be using the onboard graphics instead. I am running Lucid 32bit.
When I start up using the onboard graphics, the BIOS screen appears, then I see the normal underscore "_" flashing in the top left corner, but when that is done, my screen turns black and the monitor shuts off. I tried running a live USB and everything was fine so it's not a problem with the graphics card compatibility. I think I have to try booting into the command line and typing
Code: sudo dpkg-reconfigure xserver-xorg
but I don't know how to enter the command line. Is that what I have to do or is there a different way?
