Ubuntu Multimedia :: Video Card Switches Between /dev/video1 And Video0?
Feb 3, 2010
Seemingly at random when I reboot my PC which I do every now and then, when I get it back up and running it will sometimes have switched my video card from using /dev/video1 to /dev/video0 or vice versa. It's not a huge deal but it is slightly annoying and I would like to understand why it does it and how I can stop it from flip flopping.
Not sure what you need to know in order to answer but I use 9.10, gnome 2.28.1, the video card is a Hauppauge 150 PVR something.

I have a TV Card and a webcam connected to my computer. I've noticed that after a restart the TV Card capture device is /dev/video1 (while other times it's /dev/video0). When the device changes I have to update my tvtime.xml, which is a hassle.How can I force the capture device to be /dev/video0 and the webcam to /dev/video1?

I have 3 old video capture cards which I would like to use for CCTV. Each card supports 1 camera. So I would like to have 3 cameras setup in the end and monitor them with zoneminder. When each card is plugged in on it's own, it works fine. Video comes through clearly with xawtv and zoneminder. However as soon as I plug in a 2nd card (with or without a camera connected) the output in xawtv and zoneminder goes haywire. It looks like the 2nd card takes over the first card, resulting in majority of the picture coming from the 2nd card, and some (if any) from the 1st card. When viewing either of the two cards /dev/video0 or /dev/video1 in xawtv the output is identical. I've tried this on a fresh 10.04 Ubuntu install, and on an older MythTV debian computer, the same results. Here are lspci -vv outputs with 2 combinations of cards (same fuzzy output):

My thoughts are because the capture cards are cheap (similar to winmodems), the problem may be in the software kernel modules not allowing room for other similar capture cards to run at the same time. Can anyone suggest me in the right direction? Do I need to setup some sort of memory allocation for each card manually? Something in the BIOS? An extra option when the card modules are loaded?

I have an image generator (IG) running 64-bit Ubuntu Linux, GNOME & the SAGE application all running through an NVIDIA Quadra FX4500-X2 (dual GPU). Had to install a new FX4700-X2 (and the latest drivers) because 4500's are unavailable. The computer works fine except but I cannot watch the whole boot up sequence on the same DVI port anymore.On the 4500, all video came out the lower DVI port of the GPU with the PCI-X connector (let's call that the "a" GPU). But on the 4700 card, the screens you see during boot are divvied up between the lower DVI port of each GPU. The POST screen through Ubuntu splash screen comes out the "b" GPU while the "a" GPU is blank. The SAGE Initialization page and SAGE Desktop comes out the "a" GPU while the "b" GPU is blank.
I logged in as root and looked for a GNOME menu allowing me to force all video through the same GPU & DVI port, but couldn't find anything remotely close. Any suggestions on where I can look? Technically this IG is working, but I want to fix this to avoid future wild goose chases. The system uses 52 of these IG's.

My video card developed problems, so I followed the suggestion in this thread:
Quote: Boot into recovery mode, then choose root, for a command prompt and enter
Code: dpkg-reconfigure -phigh xserver-xorg
but my ubuntu 10.04 32-bit system still won't boot. Shortly after the ubuntu logo comes up, before the login, my screen goes black and there is no more video signal. What else can I do to reset the video configuration? The card only has this info on it: I could put the card back in the system, reboot, and then pre-configure the system to drop to the intel 865G on-board video, but the msi card has intermittent problems and will spontaneously re-boot several times during the first ten minutes of turning on the system.

My system: Pentium 4 3.6 GHz, 3 Gb DDR ram, GeForce 210 video card, Ubuntu 10.04.
I have previously used Cinelerra-cv (on Karmic) and recently Openshot (on Lucid) with not much trouble. I have been sampling other video editors (Kdenlive, avidemux, kino etc). Now I have my video card crashing whichever I use, mainly when trying to load clips. I have disabled Compiz, uninstalled all video editors and then reinstalled one at a time. I still get early video crashes whichever I try.

I downloaded camE and camorama in hope of controling my webcam's framerate for skype because right now it's 24-30 which gives me dark video. But if I lower the frame rate to something like 10, the video magically brightens. camE doesn't do anything..like it turns on my webcam and does some ftp..fails..turns of my webcam ..back to normal. Camorama can't connect to my webcame. Cheese, guvideo are successfully able to conect to my webcam and play around with it.What I want to do is edit my /dev/video0 or some file from where I can fix the framerate for skype.

I have a 'Gadget Geek VHS to DVD maker' USB device that takes analogue video in (composite) and plugs into the computer via USB.
Here is the output of lsuss (it's the eMPIA one):
Code:
Now this is essentially as far as I get, DBUS just says the following when I plug it in:
Code:
What I want to be able to do is open the (theoretical) output stream it produces in vlc and record it from there. Then I run into my next issue. There is no video* folder or link or file in my /dev directory and I can't stream video directly from the appropriate 'special file' inside /dev/bus/usb/00*/00*
My machine is ubuntu 10.4 64-bit

Running Lucid - was an LTS upgrade from 8.04.
I have a usb webcam (off brand). When installed, /dev/video0 is properly created and I can access the webcam through cheese as a regular user.
Code:
crw-rw----+ 1 root video 81, 0 2010-12-31 16:00 /dev/video0
The regular user is already a member of the video group, and I have checked all permissions under System->Admin->User/Groups->Advanced.
However, when as this regular user, I go to a website that tries to access my webcam via flash (ie, chatroulette or omegle), it does not detect the cam. (Firefox 3.6.13 with Flash 10)
I've already set the LD_PRELOAD as suggested elsewhere.
HOWEVER, if I LD_PRELOAD and run Firefox as root, all works fine and the flash plugin sees the webcam.

I'm looking to replace my video card...
From what I can tell (From Looking at forums)
Nvidia is the way to go with Ubuntu
Just want to double check that, since the newest post I found was a couple years old.
The video card I have now should be more than good enough for me.
All I do is watch videos and brows online.
But videos and desktop effects are both very choppy.
I realize that if I take the time, I can probably get my card to work well, but I just don't have the time.
Looking for a new card between $100-$150 that will work perfect right out of the box.

After a post on the wine forums came to the discovery that my ATI radeon 4850 graphics card is causing much trouble in my ubuntu machine because of the lack of support. And because of that I cannot play my favorite games through wine. So now I'm saving some money to buy a new graphic card. A nvidia this time.
Now I don't know all that much about graphic cards, but I am looking for a card that works well on ubuntu that equals the performance of my old 4850 and fits my P5Q pro motherboard.
I myself don't know much about good graphic cards so if I go off to buy something without good advice I probably end up with something that does not work or fit or something like that.

We at church are going to build a new computer to use with Datasoul, therefore I need to use 3 monitors.I've been searching about it and it seems very hard to configure Ubuntu to use 3 monitors. I know in Windows it is very easy to configure, but our budget is very small and we cannot afford to purchase a Windows license, so I need to know which video cards to purchase in order to be easier to configure; ATI or NVidia?

I'm looking to put a new video card in my desktop. I need one that will be able to handle H.264 at 1920x1080, and I would like to find one that can do HDMI with audio. Shopping for video cards, as I heard somewhere, is the kind of thing that makes you want to bang your head against a wall until you go blind, because then you won't need to worry about it any more... someone will be able to recommend a model, or at least a chipset or something, before I rip my own eyes out.

I currently use "MSI Radeon HD 3650 Graphics Card - ATi Radeon HD 3650 750MHz - 512MB GDDR3 SDRAM - PCI Express" that have no HDMI and some problems with Ubuntu. Due to the Ubuntu compatibility problems I decided to ask you guys for recommendations before upgrading to a new video card.The only "demand" is that the card must have dual HDMI outputs, one for the monitor and one for the TV.

I am attempting to make a video machine only... which mean I have a Compaq 6435cl and I have installed the latest verion of ubuntu on it. All I want this machine to do is play video from off the net on my LCD HD TV. The video on board was all choppy when going into full screen mode so I put in a 3dfx Voodoo card and the same thing happens. I cannot figure out how to install the drivers for this card in ubuntu so I was wondering if I should by a new video card. Do you have a recomended video card for ubuntu that would push HD video?

I'm working right now with a newly installed Lucid 64-bit. Everything it's fine, but I would like to use the dual monitor for my work, and so I decided to ask to buy me a video card, since what I have now is an onboard graphic that doesn't allow me to do it. I don't need to play games (well I don't think my boss will be happy about it ), and I would rather go for a not expensive solution. But I have some doubts regarding the compatibility with my linux. I found several things on the web, but nothing regarding the video cards that I individuated. If the card is auto detected, it would be better of course.
The cards I was interested are:
ASUS RADEON HD4350 1GB DDR2
SAPPHIRE RADEON HD5450 512MB DDR3
But then i've seen on the web you might have problems with ATI in linux and so I went looking also for Nvidia which I found is generally better implemented under linux: ASUS GEFORCE GT 210 512MB DDR2
PALIT GEFORCE GT 220 SUPER 512MB DDR2 I don't have many models among which to choose, because of some conventions at my workplace. The tables of compatibility with ubuntu that I found are all related with much more expensive models, or models that I don't have in my lists. Could somebody tell me if one (or more) of the cards mentioned above work under ubuntu 10.6 64-bit? I have a Hewlett Packard system with:
HP 3674h motherboard
Intel core2 duo 3.16 GHz
8Gb RAM
250 HD

I recently installed a new evga nVidia GT 430 video card in my Ubuntu 10.10 32-bit system. This had the unforseen side effect of eliminating my sound.
I had no idea that the new video card would include a new sound module. My intent is for my system to use my Soundblaster Audigy2 soundcard in 5.1 output mode. The system still seems to be configured to do that, but the nVidia HDMI Stereo output module seems to have taken over in Sound Preferences.
Here is the output of lspci:
Code:

I have a 64 bit computer with a 64 bit distribution of Ubuntu. The driver for the onboard video card wasn't supported beyond 8.04, so I didn't upgrade. Yesterday, I bought a NVIDIA GeForce 210 video card. I installed it and Ubuntu detected it and worked, but the resolution was limited to 640x480 (I think). I figured this would be corrected by updating, so I updated to 9.04. When I had to restart, the option to select which OS (Linux or Win) came up, I selected 9.04, and the ubuntu symbol came on. The status bar went to the end and the screen turned black, flickered 5 times, turned black and stopped progressing. The xorg.conf file is:
Section"Driver"
Identifier "Configured Video Device"
Driver "vesa"
EndSection
Section"Monitor"
Identifier "Configured Monitor"
EndSection
[Code]...
I tried changing the driver from "vesa" to "nv" without any effect. Does anyone have any idea what I should do to get this to work?

I'm looking at upgrading my motherboard and graphics card. Ideally, I'd like to have 2 monitors running at once (DVI), and an output to an LCD projector (HDMI). If I can't have all 3 working at once, I'd like the 2 monitors on all the time (off the graphics card), and then switch from the monitors to the HDMI output so that only the projector is getting video.
So, If I get a motherboard with onboard HDMI, would it be possible to run the HDMI out at the same time as the graphics card output?

I have a GeForce 8600M GS card in a Dell Vostro 1710, which has appeared to be playing up lately, but I'm unsure whether it's the hardware itself or have I not properly set things up.
I have Ubuntu 10.04 installed with compiz, and 'rotate cube' enabled. The 'deformation' is set to cylinder. I recently tried using rss-glx (really slick screensaver) when the slow-down and screen freezes happened.
The symptoms:
Odd behaviour begins after attempting to log in after the screensaver has blanked the screen, i.e. screensaver ran for a while then the screen blanked. When logged back in, a 'cylinder' rotate freezes and the screen does not refresh. Clicking around the screen refreshes it somewhat. Switching between screens becomes next to impossible and a restart is required.
In general rotating the cube is OK, rotating the cylinder seems a task on the video card and rotating the sphere is horribly slow.
Things done so far:
Each time I log in, I need to open the NVidia settings and change the powermizer to 'prefer maximum performance'. On next reboot I will try this in xorg.conf code...
My questions are:
- How can I verify the card is working correctly, enough to be able to decide whether it's hardware or software at fault?
- If the hardware is proven to be OK, what am I then leaving out?

I'm trying to get the screen graphics working correctly on a newly purchased ACER Aspire 7740G laptop. It has a 17.3" 16:9 screen with an ATI Radeon Mobility HD5470 512MB graphics card.
The command LSPCI in Terminal gives.....
"02:00.0 VGA compatible controller: ATI Technologies Inc Device 68e0"
I've also uploaded /var/ log/ xorg.0.log.
In System/Preferences/Display the pink coloured monitor screen has 'UNKNOWN' displayed on it with only 3 resolutions available.
I installed the ATI Catalyst Control centre but when it initialises, it produces an error saying that there is no driver installed - I thought the XORG log shows that the driver is installed.
The command ATICONFIG in Terminal reports.........
"aticonfig: No supported adapters detected" !

I tried to run the XBMC live disc but could not fully boot. Each time I could only get to a command prompt after the XBMC splash screen with spinning circle. So I thought, "Maybe because my computer is sort of old (Pentium 4, 2.26 Ghz, 512 RAM) it doesn't like the XBMC Live disc. It will probably work if I install to the HDD." I installed it only to get the same result, XBMC splash screen then loading of command prompt. Does anyone know how to fix this? Is the computer compatible?

I've tried to enable the drivers for a Nvidia 8400GS video card on Ubuntu 10.04. I've tried change desktop background > visual effects. It tells me Desktop effects can't be enabled. Sudo jockey-gtk looks and tells me no proprietary drivers are in use by my system. I've tried installing from Nvidia's site and that seems to go okay but doesn't seem to work. I have an internal video card that can't be turned off in BIOS )either ON or AUTO) that might be causing me problems.Lspci:Quote:
