  • Sound card issues (High Definition Audio Controller)

    - by Prakash R
    I have a 5-year-old Acer Aspire 4520. Until a month back it was working beautifully on Windows 7 32bit. But then out of the blue, the sound stopped working. I've tried reinstalling the OS 3-4 times. The sound came back a couple of times, but it stopped working after a reboot. Even after installing the sound drivers, I don't see any entry in the Playback tab of the Sound applet in Control Panel. I see a High Definition Audio Controller entry in Device Manager. I disabled and uninstalled it, but Windows reinstalls it automatically. I'll share specific hardware details if anybody here needs to know. The processor is "AMD Athlon(tm) 64 X2 Dual-Core Processor TK-55". Any help would be appreciated.

  • Building my own computer

    - by There is nothing we can do
    I'm planning to build my own computer. I do not have enough cash to buy all components I need in one go. I want to ask, if I buy motherboard which is compatible with i7 processor (any) and compatible with graphic card Nvidia gtx 780, does it mean that this mother board will be compatible with processors (from intel) which will be released next year? Same for graphic cards? The point is that I'd like to avoid situation where I buy motherboard let's say now, and in couple of months there will be new graphic card/processor which will not be compatible with my mother board? Or maybe shall I start completely somewhere else?

  • 64-bit Hardware Virtualization on VirtualBox

    - by Cat
    I am trying to set up a SQL Server practice lab using VirtualBox and a trial copy of Windows Server 2K8 R2 in ISO format. I received an error message that states my processor does not support 64-bit hardware virtualization. Although I "Enabled" Intel ardware virtualization in the BIOS that still doesn't work. According to the Intel website, the processor does support VT-x, however the accelerated tab in VirtualBox is greyed out and no references to VT-x are mentioned in the settings options available to me. Any ideas on how I can get around this? I checked around ServerFault and couldn't find anything but if I missed an applicable post a link is great too. Specs below - if additional information is needed please comment and I will provide. Thanks in advance. VirtualBox version - 4.1.18 Hardware - Lenovo B570 1068-A3U i3-2310M

  • Any way to tell apart a CPU defect from a mainboard defect?

    - by Pekka
    I have a fairly modern desktop computer, an AMD Athlon II X2 based silent PC, that does not work. When turned on, it will start physically (all fans are rotating, disks start up...) but not give a signal on any of the graphics ports (DVI, VGA, and HDMI, I tried all three). Also, the reset button does not seem to have any effect. I have stripped the mainboard bare of all SATA connections, extension cards, and the one 2GB RAM chip to eliminate them as the problem source, but to no avail, so I think it's fair to assume it's either the mainboard or the processor that are at fault. However, I have neither a replacement mainboard, nor a replacement processor handy to identify which one is broken. The cause of the defect is unknown, so for all I know, it could be both. Therefore, I'm reluctant to buy replacement hardware blindly before knowing more. Is there any way to further diagnose (or at least get some indication) which component is broken without buying replacement hardware?

  • Which motherboard for Intel i7 and how to get RAID working?

    - by jasondavis
    I am wanting to build a new PC, I have a couple questions. 1) I am wanting to go with the Intel Core i7 920 Processor, can anyone reccomend a good reliable motherboard for this processor? Graphics card support does not matter (sli-crossfire). I would like to support a lot of ram, so the more ram slots the better. I have read so many bad reviews about certain boards not working good, I would love recommendation from experience. 2) I am wanting to run a couple SSD drives in RAID-0, I have never done this, will I need to purchase anything additional to the MB and CPU and drives to get raid working?

  • CPU Configuration Issue for 2 Servers (Server 2008 R2)

    - by Bill Moreland
    I have 2 servers running the exact same Classic ASP code with Access DBs (yes, not ideal, but it is what it is, for now). 1) Xeon 5520 @ 2.27 GHz (6 GB Memory) 2) Xeon E5-2620 @ 2.00 GHz (2 processors, 32 GB Memory) For most pages the newer E5-2620 processes the pages between 10-15% faster. On pages requiring heavy and/or multiple complicated access stored procedures (queries) the older 5520 does a much better job. I believe the servers are configured nearly identically. My question: is it possible that the newer, multi-processor server is not as good at handling Classic ASP as the older single processor? Is there a configuration difference that needs to be in place that I'm missing since I'm shooting for identical implementations?

  • How can I check that I'm not frying the chipset on my 945 gclf?

    - by Journeyman Geek
    I'm running an old 945 gclf as a home server. Its an odd little system which has a passively cooled single core atom 230 processor, and a small heatsink/fan combo over the chipset. lm-sensors/sensors detects one temperature sensor which I guess is the processor. coretemp-isa-0000 Adapter: ISA adapter Core 0: +38.0°C (crit = +100.0°C) The fan on it is making rather horrible noises and I am considering unplugging it or using a speed reducer. There's also a risk it may fail anyway. Is there any way I can monitor the temperatures of the chipset or be warned of any issues with it? Is there anything specific I can watch out for that would indicate trouble?

  • How to load and pass a Xforms form in Orbeon (How to Send instance to XForms) ?

    - by Clem
    Hi, I am using the Orbeon Forms solution to generate messages from filled-in web forms. I read different code snippetse in Orbeon's wiki on XForms submission from a pipeline, and I tried different solutions but it doesn't work, and there is no example with a POST from a pipeline, caught by a PFC and sent to an XForms view that receives the posted data (all examples are done in the same page). I have the following pipeline which is received on his instance input: pipelineWrite.xpl <p:config ...> <p:param name="instance" type="input"/> <!-- instance containing the data of the form filled by user --> <p:param name="data" type="output"/> <p:processor name="oxf:java"> <!-- transforms the data into a file --> <p:input name="config"> <config sourcepath="." class="ProcessorWriteCUSDECCD001B"/> </p:input> <p:input name="input" href="#instance"/> <p:output name="output" id="file"/> <!-- XML containing the url of the file --> </p:processor> <p:processor name="oxf:xforms-submission"> <!-- post the XML to the success view --> <p:input name="submission"> <xforms:submission method="post" action="/CUSDECCD001B/success" /> </p:input> <p:input name="request" href="#file"/> <p:output name="response" ref="data"/> </p:processor> </p:config> Then there is the PFC which catch the actions : page-flow.xml <config xmlns="http://www.orbeon.com/oxf/controller"> <page path-info="/CUSDECCD001B/" view="View/ViewForm.xhtml"/> <!-- load the form to be filled in by user --> <page path-info="/CUSDECCD001B/write" model="Controller/PipelineWrite.xpl"/> <!-- send the instance of the form filled to the pipeline above --> <page path-info="/CUSDECCD001B/success" view="View/ViewSuccess.xhtml"/> <!-- send the instance containing the url of the file to the success view --> <epilogue url="oxf:/config/epilogue.xpl"/> </config> Then there is the success view, which is very simple : ViewSuccess.xhtml <html ... > <head> <title>Generation OK</title> <xforms:model> <xforms:instance id="FILE" src="input:instance"> <files xmlns=""> <file mediaType="" filename="" size="" /> </files> </xforms:instance> </xforms:model> </head> <body> Click here to download : <xforms:output ref="//file" appearance="xxforms:download"> <xforms:filename ref="@filename"/> <xforms:mediatype ref="@mediatype"/> <xforms:label>Download</xforms:label> </xforms:output> </body> </html> The problem is that the post is done well, the PFC catches the action well, load the correct view, but the view is loaded with no data (the view doesn't find the data on his instance input). I tried with a GET in the view to retrieve the POST data, and that's the same thing. No data is retrieved. So the download button doesn't work. I hope I'm clear enough to find a solution. Thanks in advance.

  • Gnome 3 freezes on logon on samsung RV 509

    - by Noufal
    I have a Samsung NP-RV509 A0FIN and I tried to install GNU/Linux with gnome 3.2 on it. I tried Fedora 16, Ubuntu 11.10 and Linux Mint 12 RC, but with no success.

  • Confusion of the "stack" in Assembly-level programming

    - by Bigyellow Bastion
    What is the "stack" exactly? I've read articles, tried comprehending it through my understanding, experience, and educated guessing of programming and computers, but I'm a bit perplexed here. The "stack" is a region in RAM? Or is it some other space I'm uncertain of here? The processor pushes bits through registers on to the stack in RAM, or do I have it wrong here? Also, the processor moves the bits from the RAM to the register to "process" it, such as maybe a compare, arithmetic, etc. But what actually can help understand, in some visual or verbal description or both, of how to implement the idea of a "stack" here? Is the stack actually the same in terminology with a "machine stack" meaning it's in RAM? I'm sorry, I don't want to solicit debate or arguments, but I really could use some help here if anyone can straighten things out. TO ADD: I know what a software stack is. I know about LIFO, FIFO, etc. I just want to gain a better understanding of the Assembly-level stack, what it is, where it is, how exactly it works, etc. Thanks for reading!

  • Sucky MSTest and the "WaitAll for multiple handles on a STA thread is not supported" Error

    - by Anne Bougie
    If you are doing any multi-threading and are using MSTest, you will probably run across this error. For some reason, MSTest by default runs in STA threading mode. WTF, Microsoft! Why so stuck in the old COM world?  When I run the same test using NUnit, I don't have this problem. Unfortunately, my company has chosen MSTest, so I have a lot of testing problems. NUnit is so much better, IMO. After determining that I wasn't referencing any unmanaged code that would flip the thread into STA, which can also cause this error, the only thing left was the testing suite I was using. I dug around a little and found this obscure setting for the Test Run Config settings file that you can't set using its interface. You have to open it up as a text file and add the following setting:  <ExecutionThread apartmentState="MTA" /> This didn't break any other tests, so I'm not sure why it's not the default, or why there is nothing in the test run configuration app to change this setting. Here is the code I was testing:  public void ProcessTest(ProcessInfo[] infos) {    WaitHandle[] waits = new WaitHandle[infos.Length];    int i = 0;    foreach (ProcessInfo info in infos)    {       AutoResetEvent are = new AutoResetEvent(false);       info.Are = are;       waits[i++] = are;         Processor pr = new Processor();       WaitCallback callback = pr.ProcessTest;       ThreadPool.QueueUserWorkItem(callback, info);    }      WaitHandle.WaitAll(waits); }

  • Drivers for NVIDIA 520M not working in Ubuntu 12.04

    - by Don
    I am aware that this is nominally a duplicate question, however I've read the other questions and haven't been able to resolve my problem after many hours and attempts, so please don't delete it. Additionally, it seems like many answers to the other questions are specifically dependent on certain situations. My situation being different from the others I found represented, here's my question. Until last night, I had Ubuntu 12.04 installed with Wubi, and it ran ok, though slowly and with occasional hangs. So I partitioned the drive and installed 12.04 in its own partition. Now when I start it, I am stuck using 2D. I believe this is an NVIDIA bug. My NVIDIA card is a GT 520M and my machine has Optimus. Additional Drivers only displays my wireless driver. Going to System Settings Details Graphics shows Driver:Unknown, Experience:Standard. I downloaded the driver from the NVIDIA website, and ran the installer with no errors, except that the "distribution-provided pre-install script failed". After rebooting, my screen was stuck at 640X480, which was fixed by editing /etc/X11/xorg.conf However, I still was stuck in 2D, and nothing else had changed either. A thread suggested something called Bumblebee. I tried that, and when I ran optirun firefoxI got a frozen blank screen. Following another suggestion, I checked the BIOS to try and disable Optimus. I found and ran myriad other commands to try and fix the problem and nothing changed. Now I have just done a clean re-install of Ubuntu. From there, I: Installed all the updates Downloaded the NVIDIA driver Installed it Got screen stuck at 640X480, fixed in xorg.conf. To recap the problem: I can't get the NVIDIA drivers working I am stuck using 2D I'm an idiot I think if the first one is solved, the solution to the second will naturally follow. If you need me to provide any other information, I'd be happy to. From what I've seen in other threads, I think this information may help: lsmod: dh@donsMachine:~$ lsmod Module Size Used by nvidia 12353161 0 snd_hda_codec_hdmi 32474 1 snd_hda_codec_realtek 223867 1

  • How to improve battery life on Samsung 13.3” Series 7 Ultra (NP730U3E-S01AU)?

    - by beam022
    Recently I've bought a Series 7 Ultra Samsung ultrabook and decided to change the OS from originally installed Windows 8 to Ubuntu 14.04LTS. However, it's difficult not to notice great decrease in battery life: on pre-installed Windows 8 battery would last for about 6 hours while on Ubuntu it's almost empty after 2 hours of same kind of work (wi-fi, web, vlc, spotify, intellij idea). I'm not here to say that Ubuntu's battery performance is worse than Windows, but to ask for suggestions how to improve the situation (2 hours of work is pretty poor battery life). Can you recommend some sources, applications or tips/tricks that would improve battery life on my ultrabook? I really like the Ubuntu experience, but this makes my machine much less reliable. I suspect that graphic video card might be one of the issues here. Let me give you tech specs of the ultrabook: Processor: Intel® Core™ i5 Processor 3337U (1.80GHz, 3MB L3 Cache) Chipset: Intel HM76 Graphic: AMD Radeon™ HD 8570M Graphics with 1GB gDDR3 Graphic Memory (PowerExpress) and Intel(R) HD Graphics 4000 Display: 13.3" SuperBright+ 350nit FHD LED Display (1920 x 1080), Anti-Reflective Memory: 10GB DDR3 System Memory at 1,600MHz Hard-drive: 128GB Solid-state Drive More informations here, on the official page. If it's helpful to provide additional info, I'm happy to do it, just let me know what you need. Thank you.

  • Running 64 bit Ubuntu distribution from 32 bit Ubuntu

    Related to this question How do I run qemu with 64bit processor on a 64bit machine?, I'm trying to run latest ubuntu 11.10 64bit distribution under Ubuntu 11.04 32 bit using qemu on a core2duo (64 bit cpu) machine, using following qemu parameters with no success. Error under qemu: "This kernel required an x86-64 CPU, but only detected an i686 CPU. Unable to boot - please use a kernel appropiate for your CPU" Isn't qemu suppose to emulate a 64 bit machine?

    I have got a new Samsung Series 7 laptop with dual boot setup for Windows 8 and Ubuntu 12.10. A fine machine comparable to a Macbook Pro. The Ubuntu installation was quite a hassle, but with the help of Boot Repair finally it seemed to work. Or so I thought. Windows 8 starts fine, but if I want to start Ubuntu regularly the following Machine Check Exception error occurs, quite similar to this one [Hardware Error] CPU 1: Machine Check Exception: 5 Bank 6 [Hardware Error] RIP !inexact! 33 <00007fab2074598a> [Hardware Error] TSC 95b623464c ADDR fe400 MISC 3880000086 .. [similar messages for CPU 2,3 and 0] .. [Hardware Error] Machine Check: Processor context corrupt Kernel panic - not syncing: Fatal Machine Check Rebooting in 30 seconds Kernel panic does not sound good. Then it starts to reboot, and the second boot trial often works. Is it a Kernel or driver problem? The laptop has an Intel Core i7 processor. I already deactivated Hyperthreading in the BIOS, but it does not seem to help :-( I also disabled the Execute Disable Bit (EDB) flag in the BIOS. EDB is an Intel hardware-based security feature that can help reduce system exposure to viruses and malicious code. Since I disabled it, the error did occur less frequently, but it still appears occasionally :-( It seems to be the same error as described here and here. Maybe a Samsung specific Kernel problem? A similar error also happens on a Samsung Ultrabook Series 9 (which seems to be kernel bugs 49161 and 47121). At my Samsung Series 7, it still occurs for instance during booting on battery after "Checking battery state". Perhaps anyone else has an idea? These Kernel Panic errors are reallly annoying..

  • Insufficient permissions within Eclipse when installed via synaptic in Ubuntu 12.04

    - by Clayton
    I installed Eclipse via the Synaptic Package Manager on Ubuntu 12.04 Desktop (more details on footer). However, from within Eclipse, I lack sufficient permissions to perform upgrades on my package and add-ons. I'm a recovering Windows user, and while I have a couple of years Ubuntu experience, I am unfamiliar with the command-line and mainly interact through the packaged GUI. Specifically, I am trying to install the upgrade for Eclipse CVS Clientorg.eclipse.cvs.feature.group1.3.100.v20110520-0800-7B78FHl9VF7BD7KBM4GP9C I am tracking the varying installation advice on a similar question eclipse install: Gaurav Butola Basically, the most current upgrades are available directly from eclipse?... But at some point I remember reading that the latest version of eclipse had been designed for the previous LTS of Ubuntu - I don't know if that is still true. I have read about the vulnerabilities of Java 6, and so I have gone with Open Java 7 openjdk-amd64 (if that has any relevance to which Eclipse package and installation method I choose). But I'm not crazy about the idea of creating a gksudo link in the sidebar launcher. I don't know enough about chown to use it - if that's even appropriate (I don't want stray java escaping from Eclipse and connecting to SkyNet). Another possible solution that I foresee is modifying my user's group memberships/privileges on the file system as a whole. The only other information that I think might be relevant is that I notice that Synaptic installed all of the files into /usr/ instead of /opt/ like I have seen recommended. So should I be changing ownership, reinstalling using a non-Synaptic method, or what? Any advice is greatly appreciated.

  • How do i disable intel graphics in a hybrid graphics setup?

    - by Eshwar
    Hi, I have a Dell Vostro 3700 version A10. The relevant bits from lspci -v | grep VGA are: 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18) and 01:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT 330M] (rev a2) so as you can see this is one of those hybrid graphics laptops. Now, I have no interest in any kind of switching. I would like to completely disable the Intel Graphics thats on the processor. I checked in the xorg.log file and it shows that the intel card is in use. from lsmod i see it uses the i915 module. I tried blacklisting that module in /etc/modprobe.d/blacklist.conf but that didn't really work because i still couldn't use the nvidia card for display. I wish there was a BIOS option to disable, but there isn't. Some people have also suggested changing the SATA mode to compatibility, but that does not work either in this case as the intel vga controller still shows up in lspci I tried setting the busid manually in the /etc/X11/xorg.conf file but it still didn't work. It gave me an error that said something along the lines of screen not detected. any bits of xorg.log that you'd like me to attach? So what I am looking for is some solution that allows me to completely disable the use of the intel vga controller. if it was blocked somehow it'd be nice. as if it were not present. Any suggestions? I am desperate here actually. Because I cannot use the HDMI port right now on my laptop for that reason. My guess is this applies to desktops that also have Core i5 processors with onchip graphics as well as dedicated graphics cards. How would they go about solving the problem?

  • Strange Ubuntu Random Display [Video]

    - by d4v1dv00
    I had this random display issue ever since Ubuntu 11.04 and now running Ubuntu 11.10 and this problem still persist. It is very hard for me to explain, so I uploaded a video to elaborate itself. Before I convert from Windows 7, this issue never happened. The symptom is so random that I cannot reproduce or tell precisely when will this happen again. My wild guess is, should this be related to driver? Below are my detail system information: $ lspci 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b5) 00:1d.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation H67 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 02:00.0 Ethernet controller: Broadcom Corporation NetLink BCM57788 Gigabit Ethernet PCIe (rev 01) is there any other information i need to post and how do i do that?
