• Second Monitor "Input Not Supported"

  - by Drew

  I have two identical monitors (new Acer s211hl) with a native resolution of 1920x1080. When enabling dual monitor support in Windows 7, the primary monitor works as expected, but the second monitor says, "Input not Supported" and fails to display anything. If I change the resolution of the second monitor to 1440x900, it works as expected. Likewise, if I set it to 1920x1080 with a refresh rate of 30hz, the monitor displays video. However, neither of these are solutions, because the output looks very blurry, and the content is stretched. I am using the following hardware: Monitors: Acer s211hl Motherboard: Asus F1A75M-Pro CPU/GPU: AMD A8-3850 with integrated Radeon HD 6550D graphics I suspect that there is probably an issue with the integrated graphics or motherboard not being able to output to two 1920x1080 monitors, but I am hoping for official confirmation.

• Iozone: sensible settings for a server with lots of RAM

  - by Frank Brenner

  I have just acquired a server with: 2x quadcore Xeons 48G ECC RAM 5x 160GB SSDs on an LSI 9260-8i Before deploying the target platform, I'd like to collect as much benchmark data as possible, testing I/O with hardware RAID in various configurations, ZFS zRAID, as well as I/O performance on vSphere and with KVM virtualization. In order to see real disk I/O performance without cache effects, I tried running Iozone with a maximum file of more than twice the physical RAM as recommended in the documentation, so: iozone -a -g100G However, as one might expect, this takes far too long to be practicable. (I stopped the run after seven hours..) I'd like to reduce the range of record and file sizes to values that might reflect realistic performance for an application server, hopefully getting the run times to under an hour or so. Any ideas? Thanks.

• What is the fastest RAID in practise?

  - by Luke

  I'm going to be rebuilding my server, and I want much faster access to my data. I've used RAID 1 and 0 in the past, and decided upon RAID 10 (dedicated RAID card). Then someone told me to use RAID 5+0, then someone else told me to use RAID 6+0. Assuming the Hardware RAID Card supports each level, what is currently the FASTEST RAID available, given x number of hard drives? Reliability is now another factor, and I am willing to spend money on new drives if a drive (or multiple) fail. I simply want to know what the fastest RAID level is, along with some reliability for recovering from a failure

• How can I increase the size of the hard disk used by my Virtual Machine Manager (VMM) vm?

  - by Scott Langham

  In Virtual Machine Manager admin console, I used the 'New virtual machine' wizard and created a machine from an existing template. When I got to the Configure Hardware step, I selected the primary hard disk (which is a dynamic) disk and tried to increase it's maximum size, but this control is disabled so I can't increase it. It's not big enough for my purposes. how do I increase the maximum size of the hard-disk? Thanks. Edit: I am able to add a second hard disk of a size I specify. That's not useful though as I'm trying to install some software, some of which insists on being on drive C.

• How can I disable my laptop's built-in keyboard?

  - by sam

  I have a HP Compaq Presario C700 laptop with Windows 7 installed on it. My laptop's keyboard is not working properly; some keys never work and some keys will keep on pressing. I've formatted the OS but it didn't solve my problem. I bought an external USB keyboard and it works well. As some keys in the built-in keyboard activate themselves, I still couldn't work effectively. After searching Google I tried the following steps to disable the built-in keyboard: Disabled keyboard drivers: This didn't work because when the system reboots, the driver gets installed again automatically. Installed irrelevant driver for keyboard: This failed - I couldn't install the driver. After rebooting it installed the correct driver automatically. Can anyone help explain how I can temporarily uninstall my built-in keyboard? I don't want to remove it manually (removing the hardware cable).

• Monitor has yellow tint when used with the graphics card

  - by artknish

  I have an nVIDIA graphics card when used produces an yellow tint on my monitor's display. I tried with another monitor and it had the same issue. I then switched back to my motherboard's inbuilt graphics output (not sure what the technical term is), and the display seems fine, except I can't get the optimal resolution of 1440x900 to work. So is my graphics card's life over? Or can I get it repaired? Any self remedies without calling a hardware guy? Should I try with a DVI cable? I've been using the VGA cable from my graphics card to the monitor so far. Thanks for your suggestions!

• Fastest OS for Java applications

  - by user33408

  Hello I have a multithreaded Java program. I am dealing with certain perfomance problems. I have improved everything. Hardware + Software. Now I think that it's time to move to proper Operating System. I was wondering, what OS is the fastest for Java Virtual machine? I am using Sun Java6. Do you think that Sun Solaris would be the best choice for Java applications? Or FreeBSD? or CentOS (I am using it currently)? Thanks

• Windows XP - non-user input data filter message after installing wireless keyboard & mouse

  - by James

  After I installed MS wireless keyboard and mouse and associated software, I started getting this annoying message titled "Hardware installation" telling me the software I am trying to install did not pass the XP logo tests. The software is for "HID non-user input data filter" and I have two options Continue anyway or stop installation. Now, if I try to continue the installation fails, if stop installing another message pops up with a little mouse logo and the whole process repeats itself. after I am done with that message a third dialog appears. This is happening every time I boot up my PC (a desktop), I tried following an advice I found in some forum and download windows update for ID non-user input data filter, but that installation failed as well. The thing is, that both keyboard and mouse are working fine Is there anyway to get past these dialogs ?

• Extend university wifi network

  - by asfasdoiuh ouhouhouh

  i live in a university campus and i can get wifi signal on the outside of my window but not in the house. The solution i use at the moment is a usb wifi dongle outside connected to my laptop but the lack of an internal antenna make the connection quite unreliable at times. So i was trying to find another solution to improve the reception of my network. One idea is to setup a router on the outside (in a place with stronger signal) and redirect the connection inside the house with an ethernet cable but the problem is that our Uni Wifi is managed by a capitve portal (BlueSocket with DNS redirection to login page) and the authentication has to happen on the mac address that connect to the net (so the client appliance in this case). If I use a router with Mac-Clone capability i will be able to be redirected trough the captive portal on my laptop computer and login from there or i need to setup my router to fill in the login page by itself? There are other hardware/software solutions i can use to get what i want?

• Windows 7 on 1st Gen MacbookPro Unibody (Q4-2008) - power problems.

  - by typemismatch

  I have the first generation macbook pro, purchased Q4 2008. I've been trying to run Windows 7 and can get it all installed great with the BootCamp 3.1 64 bit drivers however ... power management isn't great. The screen and keyboard don't automatically dim - the laptop gets too hot. I noticed on some newer macbook pros that windows 7 works perfectly and the above doesn't happen. Does anyone know if there really is a hardware issue with this 1st gen or is there some firmware update I can use to fix this? Thanks!

• Options to Reformat USB Drive

  - by user8783

  I have a 64GB usb thumb drive. When I plug it into a Windows system (I have tried several machines with both Windows 7 and 8), the system attempts to read it and never completes. The drive does not show up in the device manager, nor does it appear in Computer Management - Disk Management. If I click on the "Safely Remove Hardware" icon, however, I do get an option for "Eject Mass Storage Media", although it never accomplishes anything. Also, as long as the USB drive is connected, I cannot access other USB drives or even restart my computer. It seems as though it locks up Windows Explorer. Is there any option to reformat this drive? It was a great drive up until all this craziness began and I would hate to throw it out because it was rather pricey.

• Using VMware's ESXi, can I plug in 30 USB Wireless adapters and allow each of 30 VMs one?

  - by 31eee384

  I'm assuming ESXi will act very similarly to VMware Workstation or other products, so answers based on knowledge of those programs might also help. I want to plug in 30 USB Wireless or Ethernet adapters into my server, and let each VM access one and only one of these devices. Unfortunately, I don't have the hardware to just try it out as the purchase of hubs and adapters hinges on the result of this question. The answer could be a resounding "yes, easy!" and that would be great. I couldn't find any answers to this question with google, and it's possible that this is because it's so easy to do.

• What do you do with a 15 node decommissioned Itanium cluster?

  - by Gomibushi

  We are decommissioning a 15 node Itanium cluster. We don't know what to do with it. Being geeks we want to put it (or its individual nodes) to some cool use, but since it is Itanium we are a bit unsure what that could/would be. We are not bringing it back as production servers and we are considering giving them away, if anyone wants them. It's not the most spiffy hardware, but being 2U rack servers they pack an ok amount of cpu and memory, they're about 3 years old perhaps. Ideas to what runs well on them? Or something one can use them as?

• What SATA drive should I install FreeBSD onto? i.e. ar0 vs da0 vs ad4/5

  - by Matt

  I'm installing FreeBSD 8.0 on a server that has hardware SATA Raid. I'm just wondering. What is the difference between these devices. i.e. ar0, da0, ad4, ad5 I take it that ad4 & 5 are my two disks. Somehow the OS can see them individually even though it's one logical mirrored drive. Should I be installing it onto ar0 or one of the adX disks. What is da0? it's smaller than the others. ar0 is not some kind of software raid device is it? Just want to make sure I don't mess this up right from the get go.

• Soft links between samba profile and profile.V2

  - by Alex Rose

  I am currently using a samba server to host windows sessions. For the moment, every machine runs windows XP, but in an upcoming hardware upgrade, I will have new Windows 7 machines installed. The problem is that the user directory changed from XP to 7 (for instance 'My Documents' became 'Documents'). To solve that, samba created a folder called profile.V2, which contains files and folders for Windows 7. Now I would like to link the two profiles folders ('profile' from windows XP, 'profile.V2' from windows 7) so that a user can logon from a XP or 7 machine and still have access to the same files. I tried to create softlinks between folder pairs ('Documents' -­­ 'My documents') and it seems to work. My question is : is it likely to create issues in the future?

• Windows XP 32-bit + RocketRaid 622 + 4 x 3TB = not quite a RAID setup

  - by gmoney

  I'm looking to make a 6TB RAID 10 array from my new pile of drives under Windows XP 32-bit, however they are only for auxiliary storage. After adding all the drives to an array, and initializing them XP sees only a fraction of the storage, 2TB. I'm assuming this has to do with MBR vs GPT. Is making a series of 2TB volumes and then spanning my only solution? Most questions online have to do with booting from this setup, but I'm just using them as extra storage. Hardware: 4 x 3TB Hitachi Deskstars + RocketRaid 622 + Sans Digital TR8M TowerRAID. The array is connected via eSATA.

• Windows 7 automatically install usb driver

  - by Dan

  I have tried to install usb driver for Samsung arndale on Windows 7. Now it has two entries in Device Manager. I can not uninstall the one with question mark. If I uninstall both of them, when I plug in the hardware, Windows 7 will automatically install both of the entries when the circuit pulg in. I don't get the chance to choose the right driver. When I try to update the wrong driver, it says found the driver but can not install it.

• Windows Desktop Randomly Switches Resolution

  - by bobber205

  Once per log in a specific account, Windows XP is switching to 800x600 and 8 (looks like) bit color. It then after a few seconds switches back to the regular settings. This, so far, has only happened, once per log in session but it is becoming very annoying for the end user. :P Any ideas? I've tried turning off hardware acceleration as well as getting rid of her picture desktop wallpaper but nothing has made a difference. Thanks for any help!

• bad switchs duplicate my ip

  - by tacoen

  I had a large area LAN. There were many switch and AP on it, then somehow I couldn't ping my servers, and it's said that the IP was duplicated. I use arpwatch and found out that one of the switch flip-flop-ing the IP. I isolated that troublesome switch using his mac-address. But, since this a large area LAN... I doubt this will be the last cases. If there any software or hardware that I can use to prevent this kind of error? Sorry for my bad English.

• RAID setup for maximizing data retention and read speed

  - by cat pants

  My goals are simple: maximize data retention safety, and maximize read speeds. My first instinct is to do a a three drive software RAID 1. I have only used fakeraid RAID 1 in the past and it was terrible (would have led to data loss actually if it weren't for backups) Would you say software raid 1 or a cheap actual hardware raid card? OS will be linux. Could I start with a two drive raid 1 and add a third drive on the fly? Can I hot swap? Can I pull one of the drives and throw it into a new machine and be able to read all the data? I do not want a situation where I have a raid card fail and have to try and find the same chipset in order to read my data (which i am assuming can happen) Please clarify any points on which it sounds like I have no idea what I am talking about, as I am admittedly inexperienced here. (My hardest lesson was fakeraid lol) Thanks!

• Will this RAM work well in an iMac?

  - by sala_7

  I want to increase the RAM of my 2.4GHz Intel Core 2 Duo 24" iMac. I currently have 1GB of RAM DDR2 SDRAM 667 MHz. I really want to upgrade, but know nothing about RAM or hardware in general... These are the cards I found: http://www.crucial.com/eu/store/mpartspecs.aspx?mtbpoid=D4B6F603A5CA7304 Are these of quality or should I look at something else? Finally, I have 800MHz of Bus speed, couldn't I get faster RAM? Thanks for taking the time to read, and hoping you take the time to answer.

• System stuttering caused by hard drive

  - by LukLed

  My system keeps freezing for about 1-2 second every time I try to do something. For example, when I enter URL in browser, it freezes and starts working after few seconds. It is probably related to hard drive. I installed HD tune and when benchmark is in progress, causing constant disk use, everything works fine in background, there are no lags. What can be the reason of this issue? My hardware is Acer Aspire 7740G-6969 running on Windows 7.

• How to achieve redundancy across data centers?

  - by BrandonBT

  I have a LAMP server with a lot of hardware redundancy built in. I am not worried about the server becoming unavailable. What I am worried about, however, are potential network issues in the data center the server is in. What I would like to have is another server in another data center for redundancy. Load balancing is less of a concern. With that said, I am relatively clueless on two points: How to have two servers in two geographically separate data centers that have exactly the same data, in terms of both files and MySQL databases. How to ensure that all traffic coming into one data center are automatically transferred to the other database in the case of a network or server failure at the first data center. Any guidance on how to accomplish the above two problems would be greatly appreciated.

• Installing Solaris 10 on sunT5220 - ZFS/UFS raid 10?

  - by Matthew

  I am in a bit of a time crunch, and need to get two T5220's built. We were very happy to see two boxes in our aged inventory which had 8 HDD's each, but didn't think to check if they were running hardware RAID or not. Turns out that they aren't. When we install, we are given the option to use UFS or ZFS, but when we select a place to install we're only given the option of installing on one single disk. Is it possible to create a software raid 10 across all of the disks and install the OS on that? Sorry if any lingo is wrong, I'm not really a Sun guy and our guru is out of town right now. Any help would be really appreciated! Note: Most of the guides I've found on google entail installing the OS on a single disk, and then creating a separate RAID 10 on other disks. We would actually like the OS to reside on the RAID 10. Hope that clarifies things.

• Please define: "Maximum Memory Supported - 10GB, Service Upgradable Only"

  - by Droogans

  I am assuming this means that the RAM modules can only be inserted/removed from some place very inconvenient? Maybe under the keyboard? Or does this mean something more strict, as in the only way to get an upgraded module in the laptop is via some special toolset, or verified through the hardware to allow the system to recognize the new memory? I ask because I'd want to know if I need to buy my own additional RAM, since I can't seem to find a way to get to 8GB. A Google search result turned up very little other than hits for shopping. Here is the laptop in question: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4817549&sku=T78-144301
