  • Computer starts, POSTs normal, no video

    - by Annath
    So, I recently tried to start up an old computer of mine. It would not power on, so I replaced the PSU. When I powered it on, all the fans spun up and the POST beeps indicated a normal startup. The problem was there was no video output. Every couple of minutes, I hear the post code again. I think it is restarting after POST, but without video I have no idea why. Does anyone have an idea as to why this is happening, and how to fix it? EDIT: The video card is a PCI-e card. There is no integrated graphics on the motherboard. If I remove the video card, the POST indicates a missing card. When I put it back, it goes back to normal, so I know that it recognizes that the card exists.

  • Is there any multi-touch graphics tablet with Linux drivers?

    - by Zifre
    After watching the absolutely amazing 10/GUI video, I have been dying to try to implement something like this. I can do the software side quite easily, but I don't have the hardware. The Wacom Bamboo Fun would work, but the Linux drivers don't support the multi-touch features. Microsoft's "UnMouse Pad" looks like the perfect solution, but it is not commercially available yet. Are there any similar devices that would work? Alternatively, is there a way to build a DIY version? (It is fairly easy to build a multi-touch display with a webcam and IR LEDs, but it would not be pressure sensitive. Does anyone have any info on how the UnMouse Pad works and if it is possible to build one?) EDIT: I should clarify that I don't want a multi-touch display. I want the sensor to be separate from the display. If that sounds crazy, watch the 10/GUI video.

  • Remove Desktop entry from alt tab list

    - by MichaelM
    Hi I would like to know whether it is possible to remove the entry for desktop from Windows 7's alt-tab list? So far I have found a post telling me to add an entry to the registry: HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Explorer/AltTabSettings However, this reverts the alt-tab menu back to the Windows XP style, where you don't get window previews. All I really want is for the desktop entry to be gone. Cheers.

  • Laptop HDD failure imminent?

    - by Andrei Rinea
    I have an HP Compaq 615 laptop with an 160 GB 7200 rpm HDD. Hasn't been dropped or shaken, in fact it almost always stayed on my desk. I've treated it as nice as I could. The other day, however, my OS froze and I could hear a repeated clink-clink-clink coming from the HDD zone of the laptop. I had to switch off hardware-ly the laptop and re-start it. It worked very well after, including now. However I backed up immediately the core data on my USB drive and ordered an external USB HDD for periodic backups. Will it die soon or it was just a "blip"?

  • How can I make it difficult to install a new operating system on a certain computer?

    - by D W
    I want to host a website on a desktop computer running Ubuntu with a Windows virtual machine. I will give away the computer in exchange for a number of months of remote web hosting. I want to add some kind of lock (hardware or otherwise) so that the end users will have difficulty just reinstalling Windows and using the machine as they want, in contradiction to the contract. Ideally, I'd want the machine to die if reinstallation of the OS is attempted. It doesn't have to be completely insurmountable, but it has to be difficult enough to prevent casual reinstallation. Perhaps on bootup the system can check whether certain files exist on the computer and refuse to boot if they do not. I don't know if this is possible, but maybe BIOS is password protected, and searches for files before boot up. The files it looks for could be date sensitive, i.e. require remote replacement on a schedule.

  • Defragment an Exchange Volume

    - by IceMage
    The Scenario: I use a dedicated volume (RAID volume) to store all of my data for my Exchange 2007 server. Today, out of curiosity, I decided to check up on how fragmented the files on this data volume were. To my surprise, the answer is extremely. So, a three part question: First and Foremost, SHOULD I defragment this volume (after a full backup of course)? Be specific as to why not if I should not, or reasons I absolutely should if I should. Second, about how much time should I allow for during this maintenance period per gigabyte. The drives are all 7200 RPM SATA drives on a Hardware RAID 5 controller (Perc 5i/6i, can't remember), the files are extremely fragmented. (Over 5000 file fragments per gigabyte). Third, is there something wrong here? It seems to me like the drive shouldn't be this fragmented. Could something be configured incorrectly that could be causing this to happen?

  • How do I remove Xen kernel and put normal kernel on RHEL 5

    - by yan bellavance
    I have 3 identical machines (hardware wise) that all have RHEL 5.3 installed. 2 of those machines have the Xen kernel and one doesnt. I cannot install nvidia drivers on the ones that have the xen kernel and so I was wondering how I managed to do this and how to replace them with normal kernels. Could this of happened during install time when for example I was queried on certain components to install? (development,virtualization, webserver)

  • No space left on device with encrypted disk that takes all space

    - by Yosef
    I use Ubuntu 11.04. There's no space left on device. I have encrypted the disk that takes up space (maybe it's good to disable it, but I don't know how). In shell, I get this message: No space left on device I run df -I: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda1 3055616 602499 2453117 20% / none 210161 890 209271 1% /dev none 214789 8 214781 1% /dev/shm none 214789 53 214736 1% /var/run none 214789 3 214786 1% /var/lock /home/myuser/.Private 3055616 602499 2453117 20% /home/myuser df -I Edit: When I run only df: Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 48060296 45618928 0 100% / none 1538340 684 1537656 1% /dev none 1547596 808 1546788 1% /dev/shm none 1547596 104 1547492 1% /var/run none 1547596 0 1547596 0% /var/lock /home/myuser/.Private 48060296 45618928 0 100% /home/myuser Edit: I thinking about few solution but I don't know which better and how exactly to do them: to enlarge partition size (I cant install gparted - no more disk space) remove encryption of partition - I really not need that

  • How to remove iso 9660 from USB?

    - by a_m0d
    I have somehow managed to write an iso 9660 image onto my USB drive, which makes all my computer think that the device is actually a CD. I have tried various methods of removing this partition, but nothing seems to work. I have tried fdisk, which says $ fdisk -l /dev/sdb Cannot open /dev/sdb parted crashes when I try to use it on this device. I have even tried $ dd if=/dev/zero of=/dev/sdb but it just hangs with no output (either on screen or on disk). However, when I plug the USB in, it does mount, and I can view (but not edit) the files on it. edit: now the result is $ dd if=/dev/zero of=/dev/sdb dd: opening `/dev/sdb': Read-only file system I have also tried re-formatting it on Windows, but it gets to the end of the format process and then says "Couldn't format the drive". How can I remove this partition and get my whole USB drive back to normal again? EDIT 1: Trying a simple mkfs doesn't work: $ sudo mkfs -t vfat /dev/sdb mkfs.vfat 3.0.0 (28 Sep 2008) mkfs.vfat: Will not try to make filesystem on full-disk device '/dev/sdb' (use -I if wanted) I can't do mkfs on /dev/sdb1 because there is no such partition, as shown:$ ls /dev | grep sdb sdb EDIT 2: This is the information posted by dmesg when I plug the device in:$ dmesg . .

  • Mecer laptop gives me a white screen when I close the screen

    - by Dane Rossenrode
    I'm having a very strange hardware issue with my Mecer m770u laptop with intel i7 quad core, etc... I'm wondering if anyone has had this issue with any other brand/model of laptop, and what I should fix/replace to solve it...? Basically when I close the screen of the laptop, the screen often goes completely white. If I open it slowly and smoothly again, the screen returns to normal. But if I close the screen when the computer is off, and then switch it on, it boots with a white screen, and opening it slowly/smoothly doesn't help. I have to then switch it on and off a few times before it returns to normal. Makes travelling with my laptop really difficult! Any suggestions?

  • hosting environment for delivering FLVs

    - by Gotys
    What would be the ideal hardware setup for pushing lots of bandwith on a tube site? We have ever-expanding cloud storage where users upload the movies, then we have these web-delivery machines which cache the FLV files on its local harddrives and deliver them to users. Each cache machine can deliver 1200 mbits/s , if it has SAS 8 harddrives. Such a cache machine costs us $550/month for 8x160gb -- so each machine can cache only 160GB at any given time. If we want to cache more then 160gb , we need to add another machine..another $550/month..etc. This is very un-economical so I am wondering if we have any experts here who can figure out a better setup. I've been looking into "gluster FS", but I am not sure if this thing can push a lot of bandwith. Any ideas highly appreciated. Thank you!

  • Remove a file on linux using the inode number

    - by WebDevHobo
    If you create a file on UNIX/linux with special chars, like touch \"la*, you can't remove it with rm "la*. You have to use the inode number(you can if you add the \ before the name, I know, but you'd have to guess as a user that it was used in the file creation). I checked the manpage for rm, but there's no metion of the inode number. Doing rm inodenumber doesn't work either. What is the command for this?

  • Fixing sticky keys without removing the keys?

    - by Earlz
    Hello, we had an E-Machine netbook brought in today that has sticky keys. (don't ask me why we said we'd fix it) Well, I've looked at a few howtos for fixing it, but they all require removing the keys. When I tried to remove the keys, I got the key to like a 45 degree angle and it still didn't budge, so I'm pretty sure the keys are non-removable. Is it common for places to even be able to find a replacement keyboard for netbooks and is there a way to fix sticky keys without removing the keys?

  • Remove Mac OS X and install Windows?

    - by user18948
    Is there a way to completely remove Mac OS X from MacBook Pro and replace it with Windows 7? I’m not talking about Boot Camp, I’m talking about completely wiping disk of any files and partitioning it for Windows installation. Any BIOS, booting, compatibility problems? I know it’s rare to replace Mac OS X for Windows, but I have this one situation where this is needed so I would appreciate any help. Thanks!
