• How can I unregister a service with dns-sd?

  - by Roman

  I am trying to use "dns-sd" command line tool on my Windows 7 machine. I can already do something. For example I can register a service using "dns-sd -R ...". I also can browser (see) registered services using "dns-sd -B ...". What I still miss, is how to unregister a service. At the moment when I type "dns-sd -R ..." the dns-sd does not return me to the command prompt. To return to the command prompt I need to press Ctrl-C. And the service stays registered till I press Ctrl-C. What I want is to run "dns-sd -R ..." in the background regime and then I would like to have a possibility to unregister a service from the command line. One more thing which I do not understand yet is what "to look up a service" means. In my picture it should be sufficient to register a service, to see it and then to unregister it. But apparently I need to look up a service. What does it mean and why I need to do it?

• Android: getting thumbnails from specific location on sd card

  - by dykzei

  AFAIK accessing thumbnails for images via MediaStore.Images.Thumbnails would generate thumbnails at first attempt, and that's what i need to perform against specific location on sd card. The question is how to make valid URI to content under specific folder? All answers i can find use just MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI as uri to make managedQuery. And result of it is Cursor that points to all sdcard images, while none examples can be found on how to access only specific folder.

• Lag spikes at full CPU usage, maybe video card

  - by Roberts

  I am posting this thread in hurry so few things may be missed (I will update tomorrow). My PC specs: Motherboard Name - Gigabyte GA-945PL-S3 CPU Type - DualCore Intel Core 2 Duo E4300, 1800 MHz (9 x 200) OS - Microsoft Windows 7 Ultimate OS Kernel Type - 32-bit OS Version - 6.1.7601 I bougth a new video card one month ago. GeForce 210. I didn't have any problems. I wanted to overclock it, in other words: "Play with it". So I installed Gigabyte EasyBoost from CD and overclocked the GPU 590 + 110 mhz, memory to max to 960mhz from 800mhz. Benchmarks showed a little bit bigger score. Then I overclocked shader clock from 1405 to [..] (don't remeber really). So I was playing Modern Warfare 2 when off sudden computer froze when I wanted to select team, I was afk before that. I had to reset CMOS. After that I had problems with Skype: unread messages and no sound. Then I figured it out that when ever I open EasyBoost - Skype starts to glitch again. Now I use EVGA Precission X. Now after a month, I cleaned computer and closed the case, it was open all the time. I started to overclock GPU clock only (just a bit) because there was no problems that would stop me. So sometimes on heavy CPU load graphics starts to lag. Dragging a window is painful to watch too. Sometimes the screen freezes for 5 to 10 seconds (I can see that hard disk activity is maximal). You may say that CPU fault it is, isn't it? But sometimes lag spikes starts randomly when CPU load is at maximum. All 3 benchmark softwares (PerformanceTest, NovaBench and MSI Kombustor) shows that performance of my video card has dropped about 25%. BUT! CPU score is lower too. I ignored these problems but when I refreshed Windows Experience Index I was shocked. Month before (in latvian language but not so hard to understand): Now (upgraded RAM): This happened when I tried to capture Minecraft with Fraps on underclocked GPU to 580mhz (def: 590mhz): All drivers are up to date. Average CPU temperature from 55°C to 75°C (at 70°C sometimes starts these lag spikes). Video card's tempratures are from 45°C to 60°C (very hard to reach 60°C). So my hope is that the video card is fine, cause this card is very new and I want to upgrade CPU anyways. Aplogies for my mistakes in vocabulary (I am trying to type this as fast I can).

• Second network card configuration not working.

  - by Sebas

  I have 4 servers running Centos 5. All of them have two ethernet network cards. I have configured 192.168.1.x IP addresses on their eth0 card. They are all connected to the same switch using their eth0 card and they are all working. I have configured 10.72.11.x IP addresses on their eth1 card.They are all connected to the same switch - a different one from the switch used with eth0 card - using their eth1 card and they are NOT all working. Their configuration files is like: DEVICE=eth1 BOOTPROTO=static IPADDR=10.72.11.236 BROADCAST=10.72.11.191 NETMASK=255.255.255.192 NETWORK=10.72.11.128 HWADDR=84:2B:2B:55:4B:98 IPV6INIT=yes IPV6_AUTOCONF=yes ONBOOT=yes The interfase is starting and configured as I need.

• How do I get a Dane-Elec mp3/mp4 player working?

  - by user40432

  My MP3/MP4 does not plug-in and play and therefore I can not transfer any file to the MP3/MP4 dane-elec music my touch or only dane-elec with 8 gb in memory and perhapses model zt1 with radio,..and microsdhc card slot following the above link the mp3/mp4 is there and it is MP3 Player: TOUCH MY MUSIC and the complete information is on this site http://www.danedigital.com/8-Music-Media-Players/2-music-touch.html as the Technical Specifications MP3 Player: TOUCH MY MUSIC The Mp4 player has a very classy. It allows its users to play music and view photos and video. His fluent interface, its touch-pad, his radio and RDS Micro SDHC reader makes him a very complete device will become the ideal musical companion. ubuntu i am with is ubuntu 11.10 kernel 3.0.0-14-generic the latest I tried to install many applications but nothing worked. With disk utility I can see that Ubuntu can recognize something, that as a peripheral device named rockchip usbdisk user and rockchip usbdisk sd, and i can plug and play other devices, and only this mp3/mp4 do not connect to the computer with ubuntu and the device as no problem working disconnected to computer I try to see if work on Windows and it does! I can see the device and transfer files to the MP3/MP4 dane-elec folder device and use FAT32. So why can not do on Ubuntu!? What can I do and why does not work on Ubuntu? What is wrong with it?

• GTX 280 purple snow on bootup, card works without drivers

  - by Brokar

  i have owned a ASUS GTX280 for 3 years now. The card has been great all along but i started having problems 10 days ago. I was playing Diablo 3 for 1 week on max settings no problems, then suddenly my display kept getting some weird purple/colours as soon as i booted and logged into windows. Went into safe mode, updated drivers and it kept crashing. Formatted PC, fresh windows install with new WHQL drivers again same problem. Uninstalled nvidia drivers and pc has been running great for 4 days now, ofcourse i cannot run games but everything works on 1680x1050 resolution and i can browse internet,watch movies and use my PC for everything but gaming. As soon as i install nvidia drivers PC won't boot. I only wanna game a few hours a week (very busy program with school this month so it might be a blessing that i cannot game) and i would love it if i could keep the card. I am looking to upgrde later on when i will have time for gaming but i wonder if i could still use the card somehow with different/new drivers (tried older drivers that came with the card on a CD aswell) tldr: PC works fine with no nvidia drivers (apart from gaming ofc). Once i install WHQL drivers or older ones, cannot even log into windows. Fix?

• can't access SATA card config screen on boot, nor access the disks

  - by Ronald

  We've just upgraded our file server using an ASUS P6T WS Pro board, running FreeBSD-RELEASE 8.2 and using zfs to manage 12 WD20EARS disks. Since our 3ware card has been giving us trouble we started using the six on-board SATA connectors and got a SuperMicro USAS2-L8i to provide eight more ports. Mechanically, the card is an awkward fit but electrically it all seems ok. Upon boot, the LSI controller shows up and states that pressing ctrl-c will bring up the LSI Config Utility. When doing that, the message changes to state that the utility will be started after initialization, however that never happens. There does seem to be an error message that's only displayed too briefly to read and seems to be about PCI and "not enough space". (That message is pushed off by a hardware summary and I've found no way to scroll back at this point.) The disks do not show up in any recognizable ways after booting, either. I found a hint in another discussion to check the address mapping on either the card or the motherboard BIOS, but have found no way to do that. So what I tried on a hunch is to disable everything that's on-board, including network adapters, Firewire controller and SATA. In fact, after doing that, I can successfully launch the LSI Config Utility. As far as I can tell, all looks well in there, and when booting in that configuration it also displays a list of the disks connected to it, which looks just fine as well. Only problem now is that I can't boot that way, because I need the on-board SATA controller and network adapters. As soon as I re-enable any of them I'm back to square one. That discussion I mentioned about mapping addresses said to try D000, then D7FF, then DFFF, in order. The LSI Config Utility shows the card address as D000 but offers no way of changing it. Any tips or insights would be appreciated.

• Network card shuts down when stressed

  - by user142485

  I have a network card that functions fine with light use, but quits functioning after heavy use. I replaced it with a brand new one and still have the same issue, also updated drivers. It is a wired D-Link card. The Internet seems fine for a small amount of web browsing but when I run a bandwidth test it starts out fast and slows quickly until the card completely quits; I have a constant ping of the gateway going while I run this and it starts timing out after a couple seconds into the speed test. The card will stay on and the data light on it still flashes some but I cannot ping the gateway or anything else until the computer is rebooted. When I boot into safe mode I can browse and run the speed test fine with no problems. I am guessing that this is probably some program that is loading in regular mode but not safe mode that is causing the issue? I have very limited software (turned off av and firewall) on the computer but I am thinking that I'll just have to start eliminating start-up programs and see if that helps. This is on Windows 7 if that makes any difference. Anyone had a similar issue or have any other suggestions/ideas for narrowing down this problem?

• AMD processors witn graphics card bundled [closed]

  - by shybovycha

  Sorry for posting this question here - just don't know to which StackExchange website i should be writing. I've heard AMD created processors with video card bundled. So now these processors should work as fast as just usual processors with discrete video card but AMD's ones should use less power and spread less warm. Some googling around gave me the result like "AMD processors of A-series". They were mentioned to be build using that technology i described above. But on the other hand, we have a small rate of publishing and not-very-good quality of AMD drivers. I am a game-developer and web-developer so i need a powerful processor and graphics card and a lot of RAM on board (to make it possible to create a sample Grails application, for example or to create some 3D models in Maya/Cinema4D, for instance). Still i want my battery to be a long-living one, so power usage is a bit critical for me. So, my questions are: are there any processor building technology like i've described and which series they are (if they exist)? which processor shall fit the laptop the best: AMD one or i5/i7 on with nVidia graphics card for the purposes mentioned above?

  My notebook's(Compaq Presario V5000) graphic card damaged last week and after that it will be restarted when I want to boot. So I tested it via windows live, and it booted from CD without any problem (as you know in win live, the graphic card doesn't recognize, and in setting of graphic card write : unknown ) Now my question : Is there anyway to install windows without any graphic driver please ?for example, Should I delete some installation files ?! PS : I tested Windows XP , VISTA and 7 but, when it goes to GUI installation restarted again :( Thanks for your help

• NVIDIA same chipset, but different implementations - what is the difference?

  - by Horst Walter

  I have planned to buy a graphics card. When searching for a particular chipset (e.g. GTX 460) I find cards of different vendors (i.e. Gigabyte, Palit, PNY, ...). I can figure out differences in frequency, memory, and equipment. When I read test reports, usually a particular NVIDIA card is compared with its ATI/AMD "counterpart" - have not really found a comparison of all vendors for a particular NVIDIA chipset. So in order to make a decision: a) Are the drivers all the same for all the cards of a particular chipset (and provided by NVIDIA or the vendor?) b) How to figure out which card actually to buy. OK, I choose chipset, and memory, and check the card has the required ports, but then ....

• HP Envy 14, Ubuntu 10.10 and trouble with the graphics cards

  - by Carsten Gehling

  A few days ago I bought a HP Envy 14, containing 2 graphics card: An integrated Intel graphics card, and an ATI HD 5650. I've installed Ubuntu 10.10 32-bit on the machine. Most things work fine out of the box, but the graphics cards are giving me trouble. When booting, I get the message "failed to get i915 symbols, graphics turbo disabled". Then the screen blanks out during the remaining boot period. I am able to get the display working by changing to one of the consoles, then closing and opening the laptop's lid. It seems that Ubuntu gets confused about which card to use. I've read here: http://www.andreas-demmer.de/en/2010/07/18/testbericht-linux-auf-dem-hp-envy-14 that I should be able to turn off one the cards by echoing keywords into /sys/kernel/debug/vgaswitcheroo/switch, but that path is not available on my system. The BIOS does not have any methods to switch of the ATI card. Help anyone? /Carsten

• Building a PC for Work and play? [closed]

  - by Derek Organ

  Ok, Its been a long time since I build my own PC so I'm looking to get back into it again and build a new one. First off budget is about €800 excluding the monitor and windows 7 licence and mouse. (just bought a new g500) I plan on using my computer for work, lots of applications open at once but none particularly excessive (photoshop being the most demanding, mostly coding tools) I also use it for some gaming, e.g. COD, Starcraft etc. One thing I do want to do eventually is get a really good monitor with hight resolution and maybe 27" so the graphics card needs to be able to make best use of that. So a few questions 1) Is the bottle neck in performance mostly still the harddrives? 2) Aren't most processors e.g. i5 etc even i3 so far a head of other bottlenecks it makes litte difference the higher you go. Isn't the Graphics card dealing with heavy graphics so what really slows because of a slow CPU? So from this my thinking is to get a SSD drive as my primary drive for OS etc and have loads of memory e.g. 6-8GB and a decent mid level graphics card? It doesn't seem at my level worth spending much on CPU and any other parts really. I basic parts off the top of my head Case, Motherboard CPU SSD Drive SATA Drive Power Supply Memory Cooling (fan?) Graphics Card Network Card Keyboard DVD drive Mouse Windows Monitor Am I missing anything? Any helpful tips or general education much appreciated. Thanks, Derek

• 2 GPUs (for multi-monitor setup)

  - by A Dwarf

  I have a machine to which I need to connect a second monitor. This machine currently hosts a ATI Radeon HD 4770 with two DVI adapters. The second monitor to be hooked to this machine is a VGA monitor. Until I find a DVI-VGA adpater, I'm thinking installing a second graphics card which does have a VGA adapter, an NVidia card. Can I successfully run both AMD and NVidia cards on this machine? Any specifics I must be aware of, like how to ensure the ATI card to be the main card? Operating system is Windows 7

• USB Adapter for Memory Cards

  - by ktm5124

  I am looking for something like a USB adapter for video cards. It is a cable that on one end hooks into a USB port on a computer and on the other accepts any one of a variety of video cards. Essentially it's an "all-in-one" USB adapter for video cards. I'm told that they are sold all over... does anyone know what it is called or where to find them? I should clarify, by the way, that by "video card" I mean a memory card for a video camera, and that the goal is to read this video data onto a computer, from a variety of video card types, through a USB port. That way if you go to your friend's house and bring your computer, you can transfer the video data on his video camera to your computer, trusting that the adapter will have a slot for his kind of video card.

• Radeon HD4850 serious issues when using DirectX 10

  - by ricsmania

  Hello, I have a problem with my video card. Whenever I run a DirectX 10 game, it works for a few seconds (10 or so) and then starts displaying nothing but big polygons. I have tested this with Crysis and Resident Evil 5, both have the same problems. The same games running under DirectX 9 work fine, except for some small black squares once in a while. I have the following specs: Asus P7P55D LE Intel Core i5 750 Sapphire Radeon HD4850 1GB 2x2GB Patriot Viper II Sector 5, DDR3 1600 MHz OCZ Stealth X Stream 500SXS 500W At first I thought it could be the video card overheating (it has stock cooling), but the game crashes even when it's running at 50 degrees C, and it's never been higher than 70. I also thought it could be the PSU, but as far as I know 500W is enough for this computer, especially because I haven't overclocked anything. My OS is Windows 7 X64 and I am using Catalyst 10.10, but I have also tried many older versions with no success. I don't think there is a problem with the card itself, or else it wouldn't run DirectX 9 games I believe. I have spent many hours searching for a solution but I couldn't, so any help is appreciated. Thank you. EDIT: I did some further investigation about the problem, and it seems taspeotis was right, it might be related to memory. I slightly underclocked the memory from 993 to 965 MHz and the problem went away completely. Both the black squares using DirectX 9 and the weird polygons using DirectX 10. I was using RE DirectX 10 Benchmark, as it consistently crashed around the same point, and now I can play the full benchmark with no artifacts at all. Unfortunately, the underclock has an obvious hit in performance. Although it's not critical, it's definitely noticeable. So, if the video memory test software showed no erros, but the card needs an underclock to work, what might be the problem? Temperature? Voltage? By the way, I couldn't find what the default voltage for this card is. And what is a good software to try and increase it? I tried Ati Tray Tools but it has a bug that increases the clock speed dramatically whenever I change something in the Overclock tab, so I'm afraid it might fry my card. Worst case scenario, if I don't find I solution I will try to slightly increase the GPU clock to compensate for the memory clock. Thank you again.

  I have a Radeon 7850 connected to a Vizio 3D compatible TV. The TV has a function to parse and display SBS encoded content. On my old graphics card (a Radeon 5770) I just had to select the 1080p option in the catalyst control center. In this mode my TV reported the output mode as "1080p", with the new card the TV reports "1920x1080". I cannot figure out what the difference in between the 2 signals but the "1920x1080" cannot be switched into 3D mode by the TV. Weirdly, before windows starts the (in the Bios and so forth) the computer outputs in "1080p" so I know the card is capable of it. As soon as the blue login screen comes up though it changes back to the "1920x1080". I've tried everthing I can think of. Updated my drivers from 13.3b3 to 13.4, then even tried the 13.5 beta (Which I'm still on this moment). Tried all the "optimized" HD settings in catalyst, even the 720p modes show the resolution from the TV and not the "720p" (which it used to do on the old card when I had to lower the resolution of games)

• Multiple Graphics cards - Non Multi-Display Setup

  - by Alan Thomas

  Is it possible for me to utilize the processing capabilities of multiple graphics cards, even if I'm only using one monitor? I recently bought a new AMD graphics card, fairly top of the line. I also have a two year old, decent nVidia card. They're obviously very different cards. I don't really mind for gaming because my current card can handle most games fine by itself. I'm concerned about video editing programs such as Adobe Premiere and After Effects. Would the system be able to utilize the power of both cards to, say, render a video? I have both drivers still installed on my machine. And because there is only one monitor connected to my current graphics card (AMD) the nVidia would be connected to no display. So I am wondering whether it would or could be utilized in some way to help in processing video. Thanks!

• Intel hd or Mobility Radeon?

  - by Absolute0

  I have decided to get a new Dell Studio 15 laptop. They have an option of adding a "ATI Mobility Radeon™ HD 4570, 512MB" card for an extra $100 instead of the included "Intel HD Graphics" card. How do the two compare? The laptop comes with an Intel Core i3 processor, maybe the Intel graphics card would be more compatible with the processor since they're made by the same manufacturer? Thanks in advance!

• Why are graphics cards upside-down?

  - by gbjbaanb

  This is something that has always bugged me - when I install a card into a desktop (ie mini tower) case, the fan is always facing down. Surely, making the card so the components and fan is on the top would help a lot with cooling, allowing those whiney fans to spin a little slower. I know some card manufacturers tried to mitigate this by adding heat pipes and big heatsinks on the back of the card.. but they still put the bits on the same way as everyone else! So, does anyone know why they're all upside-down?

• If I run two monitors from two different graphic cards, can I still have Twinview?

  - by rumtscho

  I am planning to get a second 2560x1440 monitor for home. The trouble is, I only have 1xDVI, 1xVGA on my graphics card (a 250 GT). I don't want to buy a new graphics card until the prices for the 500 series have stabilized, so probably not before summer (or will it happen earlier? I don't remember how it was for other series, and I couldn't find long-term price history for video cards). The solution I had in mind is to get the 7600 GS from my old PC, which also has 1xDVI, 1xVGA, and run each monitor on a separate card. I have never done that, and I was wondering 1. If I will be able to run the monitors in Twinview then, or will I be stuck with separate X sessions, and 2. Whether there are some other disadvantages as compared to a single-head graphics card. (I am using the proprietary driver because I need compiz). As an aside, how do I find out whether the DVI port on the old graphics card is dual link?

• Upgraded to a GTX 580 - no video signal on boot

  - by MGOwen

  I have: New Corsair 550w PSU (should be more than enough) AsRock H61M u3s3 mobo (with latest updated BIOS) Just replaced my faithful HD 7790 GPU with a refurbished EVGA GTX 580 1.5GB. When I boot, it sounds like the PC boots to windows, and the 580's fan is spinning, but I can't get any video signal from the card. Old card and integrated graphics still work fine (when I replace and use those instead). I am using the DVI ports on the card with a DVI-VGA adapter until I can get my hands on a mini HDMI adapter tomorrow. Anyone ever heard of a GPU needed something special to make the VGA signal work? Hold down a key on startup or something? I can't even find a manual for this card.
