  • USB DVD Drive not recognised in Windows 7

    - by Kieron
    I have an external DVD drive (USB) which I'm trying to attach to a notebook but it's not recognised by Windows 7. I can see the device in the control panel, says it's working properly but doesn't show up in the explorer window so can't access it. I've got a dual boot with Ubuntu and it shows up fine in there, no problems so I know the drive and connection are fine. Have tried the upper and lower filters but no success. Thanks for any help you can provide.

  • DC on Hyper V Host

    - by Saif Khan
    I've read a few similar questions but wasn't clear. I have a small office (13) users and recently purchased a new single server (this is all I have to work with for now). Server specs Memory - 16GB Drives - 6 SCSI (2TB) PROCESSOR - DUAL QUAD I plan on making the Hyper-V host the DC and then 2 VMs, one for a file server and the other an application server. Question - since I am restricted to this single server, would it be a big issue making the Hyper-V host the domain controller? Your input greatly appreciated.

  • How do I recover from a grub renaming issue?

    - by Justin Ardini
    I am currently dual-booting Ubuntu 10.04 and Windows 7 with grub 1.98 as the bootloader. I recently decided to edit the grub menu to remove the old Ubuntu kernels, so I followed the instructions of this guide and added the line list='version_find_latest $list' to the 10_linux file, then ran sudo update-grub. Apparently I made a mistake, because upon restart I had these bootloader entries: Ubuntu, with Linux $list Ubuntu, with Linux $list (recovery mode) Ubuntu, with Linux version_find_latest Ubuntu, with Linux version_find_latest (recovery mode) When I try to load any of these, I get a grub error along the lines of, Error: not a normal file Now I can't start any version of Ubuntu to remove the line I added. What's the best course of action to be able to use Ubuntu again? Thanks.

  • How to vertically split widescreen into two virtual workspaces on ubuntu/gnome?

    - by David
    My new laptop has a big 16:9 screen, and I'm finding it hard to fully utilize it during the 95% of the time that I'm not watching HD movies on it. I'd like to set it up as a kind of virtual dual screen by splitting the physical screen into two workspaces. I know I could arrange my windows manually, but I'd like to be able to maximize a window and have it only consume half the monitor, and have its pop up dialogs centered on its half-screen, that sort of thing. Is there some kind of plug in available to do this? Thanks in advance for any pointers.

  • What are the icons contained in the Windows 7 shell32.dll

    - by ahsteele
    I wanted to change the icon used for a Custom Library I've created in Windows 7. I found a great article How to Customize the Library Icons in Windows 7 which describes exactly how to do that. However, the article uses shell32.dll and a icon location to do so. I have found an image map detailing the icons location in shell32.dll in Windows XP but was wondering if anyone knew of something similar for Windows 7.

  • Will Dolphin emulator run (smoothly) on this machine?

    - by Mark
    Product Specs: Intel® NM10 Express chipset /w Intel® Atom® D525 (dual-core, 1.8 GHz) I think the most I can put in there for RAM is 4 GB. (They don't make 8 GB SODIMM do they?) The Dolphin site is pretty vague about requirements: Windows XP or higher, or Linux, or MacOSX Intel Fast CPU with SSE2. GPU with Pixel Shader 2.0 or greater. Some integrated graphics chips work but it depends on the model (and only with DirectX 9). I'm trying to make a light-weight quiet little machine for streaming video and playing eumulators, and I'm trying to figure out the minimum requirements I will need to do what I want. I know I'm not supposed to ask for product recommendations here, so if you could just advise the minimum requirements in terms of CPU, graphics card, and RAM, that'd be helpful.

  • Which hardware changes require operating system reinstallation?

    - by Mark
    I'm about to upgrade my computer but might keep some parts. Just wandering what I would have to keep to prevent me having to reinstall my OSs, at the moment I have a dual boot setup with ubuntu and windows 7. I'm pretty sure you can't just take your hard drive with the OS on it and put it into a different box and keep going (can you?) but I know you can change the graphics cards, secondary hard drives and ram with out a problem. So what is it that you can't change? The CPU? Motherboard? Thanks for any replies

  • Intel motherboard drops HDMI output after Windows boots

    - by Nick
    I have an Intel motherboard (DH67CL) that uses Intel HD 3000 video. It has two video output ports: HDMI and DVI. Both my monitors are DVI, so I have two cables: a DVI-DVI and an HDMI-DVI. If I plug a monitor into just one of these ports, things work fine. But if I plug monitors into each of the ports, the system startup screens show on both monitors, along with the "Starting Windows..." screen, but as soon as the system boots into Windows, the HDMI-connected monitor goes to sleep. When I use the Intel video control panel, the HDMI-connected monitor is not detected. How do I get a dual-monitor setup to work?

  • Grub loading. The symbol ' ' not found. Aborted. Press any key...

    - by John
    Hi there, I have a dual boot system on dell xps 9000 with windows 7 and ubuntu. But after I performed system backup on it as requested by windows 7 I am no longer able to boot into the computer, instead at the beginning after bios I get the following message: Grub loading. The symbol ' ' not found. Aborted. Press any key... I tried to change bios booting config to starting with harddrive and it still returned the same message. Using windows boot disk only asks me to do another system backup or threatens to delete my harddrive completely. The only solution I have so far is to reinstall ubuntu, but that leaves 2 additional copies of ubuntu on my computer. Is there a simpler way to fix the situation so I can actually boot into windows? Thanks so much.

  • Caching DNS server (bind9.2) CPU usage is so so so high.

    - by Gk
    Hi, I have a caching-only dns server which get ~3k queries per second. Here is specs: Xeon dual-core 2,8GHz 4GB of RAM Centos 5x (kernel 2.6.18-164.15.1.el5PAE) bind 9.4.2 rndc status: recursive clients: 666/4900/5000 About 300 new queries (not in cache) per second. Bind always uses 100% on one core on single-thread config. After I recompiled it to multi-thread, it uses nearly 200% on two core :( No iowait, only sys and user. I searched around but didn't see any info about how bind use CPU. Why does it become bottleneck? One more thing, here is RAM usage: cat /proc/meminfo MemTotal: 4147876 kB MemFree: 1863972 kB Buffers: 143632 kB Cached: 372792 kB SwapCached: 0 kB Active: 1916804 kB Inactive: 276056 kB I've set max-cache-size to 0 to make sure bind can use as much RAM as it want, but it always stop at ~2GB. Since every second we got not cached queries so theoretically RAM must be exhausted but it wasn't. Do you have any idea? TIA, -Gk

  • Vista won't boot - just get black screen

    - by DisgruntledGoat
    When I boot into Windows Vista (Ultimate), I just get a black screen (with the mouse visible and working). If I run in safe mode, it seems to pause for a while when loading crcdisk.sys. A lot of research says it could be a problem with the hard drive, but I dual boot Ubuntu and that works fine and I can still see and use the Windows partition absolutely fine from Ubuntu. I tried using the "startup repair" option on the Vista install disk but it didn't detect any problems. I have run chkdsk several times, with this: chkdsk C: /f /r And also drive D (the recycle bin). The first two times it detected and fixed errors on the C drive but now it doesn't detect any errors. Is there anything else that could be causing this problem?

  • Better to develop Ruby project on server or buy a faster desktop computer? B/c laptop too slow.

    - by user33184
    I have a Linux laptop (Vostro V13) running a Celeron M chip. This is a fine laptop, but running unit tests especially for Rails applications is slow. I want a faster development environment but I don't want to spend too much money. So the choice I have is between $390 for a Linux desktop machine with a Pentium Dual Core Processor E5400 and just paying between $30 and $40 a month to Linode and trying to do development remotely on that server. Can anyone with experience developing server applications using both methods offer any advice?

  • Rack layout tools

    - by Luke
    I'm wondering if there's any tools (preferably offline) that would allow me to layout all of the new equipment that will be going into several standard racks. Currently I'm using Excel to map out all of the slots columns for the data but I suspect that there is some better method of doing this. Suggestions? Edit: Dell has an online tool, but doesn't seem very good at actually saving the data that you're working on (and obviously it's geared towards Dell hardware).

  • Will Software RAID And iSCSI Work For A SAN

    - by Justin
    I am looking for a SAN solution, but can't afford even entry level solutions. Basically, the SAN is for development and a proof of concept product. The performance doesn't have to be amazing, but needs to be functional. My buddy says we should just setup sotware RAID and software iSCSI in Linux. Essentially I have a spare server with dual Xeon processors, 4GB of memory, and (2) 500GB 7200RPM drives. It's a bit old but working. I am sure there is reason people don't do software RAID and iSCSI, but will performance be usable? Thinking of configuring the drives in RAID 0 (for performance).

  • Ubuntu Karmic, Maximize delay problem

    - by Loukas990
    Hello, I have tried various ubuntu versions, Ubuntu Karmic Koala 9.10 x86, Ubuntu 10.04 beta DVD, Ubuntu 9.10 AMD64, Mandriva 2010 x86, also a Fedora version and after installing compiz on all OS's, everything is working normal and smooth, even the compiz effects, cube, water, fire, wobbling windows, etc, except of the Maximize effect, where i get 2seconds+ delay for the effect. Cause it got me in a lot of thinking, why im getting this delay "problem", do you think there is any solution? or at least a way to decrease the delay? Thanks in advance. ;) P.S. My laptop is a Toshiba Satellite P300d, AMD Turion 64 x2 Dual-Core TL-64 (2.20 GHz), ATI Mobility Radeon™ HD 3650 512MB, 3GB RAM.

  • 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.

  • Semantic is consuming all CPU, causing emacs to hang

    - by Cheeso
    I upgraded to emacs 23.2.1 on Windows 7, not long ago. Since then I've been unable to use Semantic. As soon as I start it, the cpu goes to MAX . (actually, Windows reports it at 50%, but this is a dual core machine, so emacs is effectively consuming 100% of a core). Emacs becomes non-responsive. Is there a particular combination of versions of semantic and emacs I that is unsafe to use together? how would I debug this spin/hang? I've seen other suggestions to change the semantic-idle-scheduler-idle-time, from its default 2 to something very large. I tried that, but got the same results.

  • Windows Server 2008 Migration - Did I miss something?

    - by DevNULL
    I'm running in to a few complications in my migration process. My main role has been a Linux / Sun administrator for 15 yrs so Windows server 2008 environment is a bit new to me, but understandable. Here's our situation and reason for migrating... We have a group of developers that develop VERY low-level software in Visual C with some inline assembler. All the workstations were separate from each other which cased consistency problems with development libraries, versions, etc... Our goal was to throw them all on to a Windows domain were we can control workstation installations, hot fixes (which can cause enormous problems), software versions, etc... All Development Workstations are running Windows XP x32 (sp3) and x64 (sp2) I running in to user permission problems and I was wondering maybe I missed one, tWO or a handful of things during my deployment. Here is what I have currently done: Installed and Activated Windows Server 2008 Added Roles for DNS and Active Directory Configured DNS with WINS for netbios name usage Added developers to AD and mapped their shared folders to their profile Added roles for IIS7 and configured the developers SVN Installed MySQL Enterprise Edition for development usage Not having a firm understanding of Group Policy I haven't delved deeply in to that realm yet. Problems I'm encountering: 1. When I configure any XP workstations to logon our domain, once a user uses their new AD login, everything goes well, except they have very restrictive permissions. (Eg: If a user opens any existing file, they don't have write access, except in their documents folder.) Since these guys are working on low system level events, they need to r/w all files. All I'm looking to restrict in software installations. Am I correct to assume that I can use WSUS to maintain the domains hot fixes and updates pushed to the workstations? I need to map a centralized shared development drive upon the users login. This is open to EVERYONE. Right now I have the users folders mapped upon login through their AD profile. But how do I map a share if I've already defined one within their profile in AD? Any responses would be very grateful. Do I have to configure and define a group policy for the domain users? Can I use Volume Mirroring to mirror / sync two drives on two separate servers or should I just script a rsync or MS Synctool? The drives simply store nightly system images.

  • how insecure is my short password really?

    - by rika-uehara
    Using systems like TrueCrypt, when I have to define a new password I am often informed that using a short password is insecure and "very easy" to break by brute-force. I always use passwords of 8 characters in length, which are not based on dictionary words, which consists of characters from the set A-Z, a-z, 0-9 I.e. I use password like sDvE98f1 How easy is it to crack such a password by brute-force? I.e. how fast. I know it heavily depends on the hardware but maybe someone could give me an estimate how long it would take to do this on a dual core with 2GHZ or whatever to have a frame of reference for the hardware. To briute-force attack such a password one needs not only to cycle through all combinations but also try to de-crypt with each guessed password which also needs some time. Also, is there some software to brute-force hack truecrypt because I want to try to brute-force crack my own passsword to see how long it takes if it is really that "very easy".

  • Why does Windows 7 need hardware virtualization to run XP mode?

    - by Ken Pespisa
    I have a MacBook Pro and I've run VMware Fusion's unity mode and Parallels' cohesion mode along side the Mac OS X, and both work pretty seamlessly. I figured XP Mode in Windows 7 would be something similar, but I then learned my machine requires hardware virtualization support, which it does not have. My machine is an HP dc7800. That's a dual core 2.2GHz machine with 4GBs of RAM. Certainly it has the horsepower to run a virtual environment alongside the primary OS. I'm wondering: 1) Why Microsoft decided to make hardware virtualization a requirement and 2) What am I missing? Is the experience similar to Parallel's cohesion mode / Fusion's unity mode? Thanks!
