• How do I fake 2 discrete monitors using a DualHead2Go?

  - by Sietse

  I just got a [Matrox Dualhead2Go|http://www.matrox.com/graphics/en/products/gxm/dh2go/] for use with my MacBook Pro. I realise that the reason it works is that it fakes 1 big (wide) monitor. I also kind of depended on the software that came with it to trick OSX into accepting it as 2 monitors. Turns out the support is kind of lame: it just adds shortcuts for maximizing the window to whatever screen you want. And it even gets that wrong, since my dock doesn't auto-hide, but it doesn't take it in account while resizing, causing my window do end up "behind" my dock. (I've made a AppleScript that does the resize correctly, that I'll post below). There's two glaring issues this causes: Full screen (video, etc.) takes up both monitors, and dialogs just pops up in the middle. Is there a way to trick OSX, or at least a way to fix these issues?

• Computer not displaying anything

  - by Justen

  The computer in question worked last week. It's brand new, never been connected to the internet, up-to-date parts, etc. Last week, I installed some 3D software on it, then shut it down and waited for the license files that arrived this week. I've done this to 4 other PCs with the same hardware and software. I've tried: Hooking it up to 3 different monitors using different video cables 2 other graphics cards and a handful of other things like switching which port it's plugged into before and after a restart. I have the driver disc, and a windows reinstallation disc, but they won't do me any good because no display at all for any interval of time. All the fans are moving: psu, gfx, cpu etc, so I don't believe it's a power issue. Here are the specs I know of: 4GB RAM 8800 GTX 700w PSU Intel dual core (not sure of model) Anyways, I'm open to ideas.

• Sudden restart when Ubuntu almost loaded from disc.

  - by Wesley

  Hi all, Here are the specs beforehand: ECS K7SEM motherboard AMD Duron 900MHz 2x 256MB PC133 SDRAM The Best Power MT-500P 500W PSU Integrated graphics No hard drive DVD-ROM - will update with brand & model Now, I was starting up this machine after it was left outside for 3 months in winter weather. (I got this from a friend.) I was able to get it started and tried to load Ubuntu from the DVD-ROM. It was fairly successful and got up to the point when the Ubuntu logo is glowing. However, when Ubuntu was about to go to the main screen, the computer crashed and automatically rebooted. Is there any reason why this is happening? Also, I should mention that when I try to hit Delete on the BIOS screen to go to Setup, it only shows a screen with four lines saying something Novell something... I will edit with exact lines. Should I be resetting the BIOS or something? Thanks in advance.

• Micro sound breaks/interrupts on Windows 7

  - by cand

  Hello all, I've been experiencing strange behavior recently. When listening to mp3 or watching movie or whatever that uses sound, I get micro breaks in sound. It's like it hangs or cuts a fragment for about 0.5s. When I start OS, it's ok, but as time passes it gets worse, to the extent that music is unlistenable being interrupted every 2 seconds. I haven't found any relevance between this behavior and hardware usage, I don't think it's directly related to HDD (or it might be but with significant delay). I have updated soundcard drivers and it didn't help a lot. My system is Windows 7, computer is simple HP laptop, nx7300-Ru374ES with WD Caviar Scorpio Blue hard drive inside and integrated soundcard on it (I can check the model later if it's important). Did anybody encounter such problem ? Maybe it's a common thing on Windows 7 or someone knows how to solve it? Thanks in advance.

• Computer Components

  - by Martin

  What is the role of a motherboard in terms of how components communicate with the processor (via the system busses). Therefore, for each component, which communication bus is involved and what is the route that data takes from the component to the processor, including; The bus name Whether bus is serial or parallel The name of any bridges involved Also, what is the the role of a bridge The components are: Internal components: Floppy Drive, Hard Drive, CD/DVD Drive, Memory, Processor Power supply, Graphics card & Sound card External devices: Monitor, Keyboard, Mouse (PS2 & USB), Printer, Pen Drive I have absolutely no idea of what the routes are and how motherboards communicate, could someone give me a start here? Thanks.

• Dell Dimension running Fedora12 does a "Sleeping Beauty" and I am not am not a "handsome prince"!

  - by Jim Dobbs

  Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

• How do I make my Geforce GTS 250's power save mode stop causing audio stuttering?

  - by Matt

  Whenever my GTS 250 enters its power save mode, downscaling its frequencies, my audio stutters. This affects both my onboard audio and my Audigy Soundblaster 2 ZS. Changing Windows power save mode options such as PCI-E link state power management or Power Management Mode in the nVidia control panel have no effect on this issue. Replacing the power supply had no effect on this issue. The BIOS is the latest version, and I have the latest motherboard chipset and graphics drivers installed. I do not overclock. I started to see this issue after I upgraded my rig from its Socket 939 board to a Socket 1156 board with a Core i5-750 while simultaneously upgrading from Vista to 7.

• Why did my laptop turn off?

  - by darenw

  Normally I can slip my running laptop into a backpack, go somewhere, and if it's no more than about half an hour later, it'll still be running. At the destination I plug in the AC power unit and all is well. I run it off of the AC unit before and after the trip, have the screen at less than full backlight brightness, and don't have any peripherals that burn power. Sometimes the wireless switch accidentally slides in the backpack, and that causes extra power to be used and the laptop dies before I reach the destination. Sad, but so be it. But sometimes the wireless switch is off, I've reached the destination in less than 30 minutes (typically 10-20 min), and I know the battery was fully charged, yet the machine is off. Is there a way to determine, after the fact, why the machine shut itself off? I'm running Linux on a fairly powerful Gateway with 4GB RAM, fancy nvidia graphics, dual core cpu, chosen more for number crunching power than battery life, but should last easily for half an hour if not an hour.

• Unable to extend desktop

  - by CSharperWithJava

  I'm trying to hook up my TV to my computer as a gaming/multimedia center but I'm having troubles setting it up. I have a custom built machine running Windows 7 RC. It has an ATI Radeon 4800 video card with 2 dvi output and 1 S-video output. I have an s-video to composite adapter that connects to my tv. (It's an old TV with only Cable, composite, and s-video connections). I can switch the desktop to my TV without a problem, but I can't duplicate or extend my desktop onto it. I've installed the latest drivers and Catalyst Control Center, but it won't let it work any more readily than Windows would. Any suggestions? Would using an s-video cable instead of the adapter change anything? (The only reason I use the adapter is because it came with the graphics card) (Edit) I installed the latest drivers and I can now duplicate the screen (show on one monitor and on the TV), but I still can't extend the desktop.

• VGA resolution with Sony Bravia TV

  - by prestomation

  I just bought Sony Bravia KDL40S5100 tv. The VGA input is acting weird. I have a Gateway desktop with Windows 7 and Intel 945 graphics. I also have a laptop running Ubuntu 9.04. The TV will not display the gateway when the resolution is over 1360x768, I have to wait for it to time out and bring me back. The Intel driver even urges me to switch to the "recommended" 1920x1080. I just installed Win7 using this tv as the monitor. When the orginial welcome screen started after setup, it started me at 1080. I had to start in safemode to set a res that would work! When I plug my laptop into the TV, 1920x1080 works just fine. Any ideas? This laptop also has Win7, which I am going to try, but I haven't gotten a chance yet.

• SQL Server 2000 + ASP.NET: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'

  - by Rick

  I just migrated a development workstation FROM: Windows XP Pro SP3 with IIS 6 TO: Vista Enterprise 64bit with IIS 7 Since the move, one of my pages that accesses an SQL Server 2000 database is receiving the following error from my ASP.NET 2.0 web page: "Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'." I have: enabled Windows Authentication in IIS and web.config disabled Anonymous Authentication in IIS set up Impersonation to run as the authenticated user verified that the logged in user (in this case, me) has access to the appropriate database on the SQL Server verified that my login and impersonation information is correct in the ASP.NET page by checking User.Identity.Name and System.Security.Principal.WindowsIdentity.GetCurrent().Name (both display my username) My connection string using SqlConnection is "Server={SERVER_NAME};Database={DB_NAME};Integrated Security=SSPI;Trusted_Connection=True;" Why is it trying to login with NT AUTHORITY\ANONYMOUS LOGIN? I have to assume it's some setting or web.config entry specific to IIS7 since it worked fine before the migration. NOTE: The SQL Server is Windows authentication only - no mixed mode or SQL only.

• Change Linux Console's Default Monitor

  - by Tim M

  Is there any way to specify which monitor the console is displayed on in Linux? Details: I have a 3 monitor setup with 2 video cards. When I boot the computer, the BIOS displays on the PCI graphics card (which has a small monitor). When starting Linux, the console is displayed on the same monitor. Is there a way to have the console output on a different monitor? I'm using the vesafb framebuffer. I don't see a way in my BIOS to change the default video card.

• Error installing Windows7 64 bits on VirtualBox

  - by MetaDark

  I am trying to set up Windows in Virtual Box, so I don't need to reboot in the rare occasion that I actually need it. The problem is, Virtual Box doesn't preform any errors when I insert the 32bit installation CD but when I try to use the 64bit installation; What!? I am already using the installation disc! I've checked my BIOS to see if I have SVM (AMD's version of VT) disabled and all I see is "Enabled" I have a K9N6PGM2-V2 motherboard A Triple Core AMD Athlon II A Nvdia NForce 430 integrated graphics card 4GB of RAM An 80GB IDE And a 1TB SATA I don't think the last three specifications matter but just in case XP I am pretty sure the CD isn't broken ( I am going to make sure in just a moment ), what could be the cause to this problem? Edit: The 64bit installation CD is not broken, but I found out when trying to install from the 32bit version that it's trying to upgrade, not preform a fresh install - Odd.

• What are the limitations of virtual machines?

  - by j-g-faustus

  I'm considering setting up a virtual machine running Windows, with Ubuntu 10.10 as the host OS, for those cases where I have a Windows-only program. I understand that using a VM will lose some performance, but are there other limitations to what the OS in a virtual machine can do compared to "running on bare metal"? For example: Can a VM play games, like Dragon Age Origins or Civilization V? (Possibly with poorer framerates and/or lower resolution, but does it play at all?) Can a VM rip DVD/Blue-ray using AnyDVD or similar Windows program? Can a VM handle new hardware that requires dedicated drivers, but the drivers are only available for the OS running inside the VM? (Ex. graphics card, digital camera, card reader for smart card authentication.) Is it possible to say anything about "general limitations" of VMs, or is this wholly dependent on the specific VM?

  - by dasko

  have a server 2003 domain controller i have installed active directory integrated dns under the forward lookup zone for domain_name.local i see an APIPA ip address that is set for (same as parent folder) with ip number 169.x.x.x looks like (same as parent folder) Host A 169.x.x.x (apipa subnet range) problem is, from other forums that i have read, that this is due to dual nics and one on that is not getting a dynamic or static ip address BUT... I only have one nic in this server? where could this be coming from and could it mess up other settings or not allowing the DC to be contacted? i am just wondering what symptoms could arise due to the record being there. any help would be greatly appreciated thanks.

• 912 stream processor available in OpenCL

  - by tugrul büyükisik

  I am thinking of assembling this system: AMD CPU (A8-3870 APU which has Radeon HD 6550D inside: 400 stream processors:xxx GFLOPS) nearly 110$ AMD Graphics card: HD 7750 (512 stream processors:819 GFLOPS peak performance) nearly 170$ Appropriate ram (1600MHz bus) Mainboard What GFLOPS level can I reach as a stable mode with using OpenCL and similar programs? Can I use all 912 stream processors at the same time? I am not trying to do a VS question. I need to know what could be better for scientific computing (%75 of the time) and gaming (%25 of the time) because I have a low budget. With "scientific calculations" I mean fluid dynamics/solid state physics simulating; with games I mean those that need openCL and PhysX.

• tacacs integration with database

  - by chingupt

  We are setting up TACACS+ in our network which is a mix of Cisco AP's and other brands. However we have a centralized managemnet system which allows our customers to centrally configure services. Hence we would like to setup a tacacs+ server integrated with some database. Can this be done? I found the following package at www.shrubbery.net/tac_plus/ but it does not have the necessary plugins for database. Please let me know how to go about this. TIA Sachin

• Which CMS for a mobile app? No HTML, just XML or JSON.

  - by Sascha

  I am a newbie in content management systems. I would need a CMS that can transfer content by XML or JSON to a client. It is ok if the CMS can also manage HTML websites, but the priority is on the data transfer over a web service. Which is the best CMS to use here? I want to avoid spending endless hours learning all the big CMS systems just to find out that they don't support this feature or that it's badly integrated. Thanks.

• How do I get Windows 7 wallpaper to display the company logo properly?

  - by David Silva Smith

  Windows 7 is not displaying our company background properly. Curves show pixelation and straight lines are jagged. I'm working with a scalable vector graphics (SVG) image that I've exported to the same resolution (pixel dimensions, to be technical) as the desktop, which is 1440x900. I have tried exporting the image as a .png, .jpg, and .bmp. All of these look correct in an image viewing program, such as Windows Photo Viewer and Paint, but when I set the Windows background to these images, curves show pixelation and straight lines are jagged. Reading online, it seems that behind the scenes, Windows is converting the image to a .jpg with low quality compression, which is causing the issue. I've tried setting the image as a background through Internet Explorer, saving it as a .jpg, and putting the file in the Windows photo directory as suggested in some online forums, but none of those solutions have fixed my issue.

• Screen flicker -> Severe System Slowdown?

  - by Adam Robinson

  I'm using a Dell D830 laptop, and over the last few weeks it's been developing a very irritating screen flicker problem that leads to the system slowing down almost to the point of unusability. At seemingly random times (no commonality between how long the system has been running, what I was doing, what applications were open, etc.) my screen (I use two external LCD's with the laptop closed in a dock) flickers for a moment, then the system becomes incredibly slow. The screen redraws painfully slowly--almost like what you might expect to see with generic graphics drivers installed--and the entire system is maddeningly unresponsive. The only thing that seems to be able to correct the issue is a restart. I've checked the event logs and nothing out of the ordinary is there, and definitely nothing that's common to all of the events. I'm running XP Pro SP2. Any ideas?

• 64 Bit Windows drivers for Inspiron 1720

  - by Rob Allen

  Dell doesn't seem to offer 64 bit drivers specifically for the Inspiron 1720 (laptop). I'm going to be upgrading from Vista 32-bit to Windows 7 64bit and I want to pull down the necessary stuff before hand. Are there any Dell systems that are similar enough to the Inspiron 1720 that I can use for a baseline to make sure I still have Ethernet and WiFi after the reinstall? It doesn't matter if they are for Vista 64 or Windows 7. Identified hardware: Processor: Intel mobile Core 2 Duo T7500 Chipset: Intel Mobile 965 Express Wifi: Intel Pro Wireless Drive Controller: Intel Matrix Graphics: nVidia GeForce 8600M GT Bluetooth: Dell TrueMobile 355 + EDR Ricoh card reader I think anything else, the default Windows drivers will be sufficient. Let me know if you think I missed something thing please.

• New Session Failed

  - by PhilPursglove

  We've started to see instances on our Intranet server where for any page the server just responds with the error page 'HTTP/1.1 New Session Failed'. It seems we can fix it by running IISRESET but this feels like we're only treating the symptom. The server is a virtualised server running IIS6 on Windows Server 2003 with 0.5Gb of RAM. Our Intranet is written in ASP, but we also have ASP.NET 2.0 applications running on the web site. The site is set up for Anonymous and Integrated Authentication. What causes IIS to get into this error state? Could the server be saturated with requests i.e. we need to scale out and move some applications onto another server? I've seen KB210842 but I'm not sure it applies as that is applicable to IIS 4
