  • Blank pale blue screen with Live USB Kubuntu on AMD Sempron 2800+ processor

    - by WGCman
    I am trying to install Kubuntu onto a USB stick to use on my Acer Aspire 1362 laptop with an AMD Sempron 2800+ chip. Using Windows XP, I downloaded and saved to the laptop's hard drive: kubuntu-2.04.1-desktop-i386.iso from the GetKubuntu website and LinuxLive USB Creator 2.8.16.exe from the Linux live website I then installed the latter and ran it, installing the kubuntu onto the Memory stick. Leaving the Bios setup unchanged, the USB stick is ignored and Windows boots. If I change the Bios boot order so that the memory stick takes precedence, I see a dark blue screen announcing Kubukntu 12.04, and on selecting either “live Mode” or “Persistent mode”, messages flash by quickly, some of which appear to be error messages, including “trying to unpack rootfs image as initramfs”, “cannot allocate resource for mainboard”, “no plug and play device found”. Eventually I see a pale blue screen with four moving dots announcing Kubukntu 12.04, similar to the login screen of my Kubuntu desktop, but no invitation to log in or indeed any dialog. After several minutes, this changes to a black screen with more messages including “no caching mode present”, “ADDRCONF(NETDEV_UP): wlan0: link is not ready”, then degrades to a blank pale blue screen which can only be moved by switching the computer off. Finding no way to log the error messages passing by, I managed to photograph most of them, but know no way to attach the photo to this forum. As suggested by User 68186 (to whom thanks!), I have edited my original post to reflect the recent progress, so the following two comments are now superseded.

  • Is there software that lets me drag windows between two PCs? (there is!)

    - by Jonathan
    I'm looking for a preferably free program that is similar to MaxiVista, which lets you extend you desktop to another desktops screen on the same network. But with MaxiVista you have to extend the entire screen. I'd like to just drag one window onto the other computers screen without extending the desktop. So on top of the other computer's windows. Kind of like a cross between MaxiVista and Windows 7' XP mode where you can run XP programs on the windows 7 desktop. EDIT: I am pleased to announce this is possible, though the windows is poor quality (8-bit color) but I believe thats just because MetaVNC isn't very up to date.

  • Copy files between two windows machines on seperate domains

    - by Simon
    I need to copy several database backups between two computers. The source computer initiates the copy and is a Windows 2000 pc and is a member of domain1. The destination machine is running Windows Server 2000 and is a member of domain2. The machines are on separate networks physically connected via a firewall. The files are currently copied via ssh with http://sshwindows.sourceforge.net/ installed on the destination machine. There is no need to encrypt the contents during the copy, however the passwords should not be sent in the clear. I am looking for a way to copy the files without having to install a server on the destination. I specifically need help with how to set up the permissions and what ports would need to be opened on the firewall.

  • Stacks in C++

    - by MarkPearl
    So some more basics… One of the things you will be taught at any college after conquering arrays is different derivatives of collections. Stack is one of the simplest of those and very useful… A stack is a LIFO (last in first out) data structure and has at least two basic method calls – push & pop. Push, “pushes” an item on the top of the stack. Pop, removes the top most item off the stack. Because all elements on a stack are of the same type, one can use an array to implement a stack or a linked list. With the array based approach, the first element in a stack would be the first element in the array, the second on the stack would be the second on the array, etc. One limitation with an array implementation of a stack is that unless the array is dynamic, one would have to have a preset max stack size (based on the bounds of the array). Linked lists is another approach that gets past this boundary by allowing you to dynamically grow or shrink a collection of data. Stacks have many applications… a typical computer science example would be Postfix Expression Calculator, where the LIFO principle is maintained.

  • Extending C drive not possible

    - by gokul
    This is my computer partition list. You can see my C drive is running very low on disk space. I wanted to extend my disk space, so I used mmc Disk managment to shrink a volume, but I can't extend it to the C drive because the extended volume in dropdown list of C is not clickable. I've tried many packages, but none were able to do it. My C drive is simple, basic, NTFS, healthy (boot, crash dump, primary partition). The MMC Windows: What should I do?

  • Using PowerShell, in Active Direcotry, how would I change all the DNS A records that have a given IP to a new IP?

    - by djsumdog
    We've been moving data centers and I have a lot of old records that were not correctly but in DNS as CNAME records, but A records that have a direct IP (e.g. 192.168.100.n) and they're all moving to a new subnet (10.19.100.n). I just need to write a powershell script to change all those records. I found this site: http://www.indented.co.uk/index.php/2008/12/30/administering-microsoft-dns-in-powershell/ and from it I made this simple script: $dnsServer = "meldc2" $scope = New-Object Management.ManagementScope("\\$dnsServer\root\MicrosoftDNS") $path = New-Object Management.ManagementPath("MicrosoftDNS_Zone") $options = New-Object Management.ObjectGetOptions($Null,[System.TimeSpan]::MaxValue, $True) $ZoneClass= New-Object Management.ManagementClass($scope,$path,$options) $Zones = Get-WMIObject -Computer $dnsServer -Namespace "root\MicrosoftDNS" -Class "MicrosoftDNS_Zone" $Zones | Get-Member foreach($Z in $Zones) { $Z | Select-Object Name,DsIntegrated,ZoneType,Reverse,Data } but that only gets me a listing of root zones. I don't understand how to iterate over all the entries in each of the zones. Also, all the examples I've seen involve adding new zones, but there aren't any examples I can find on modifying existing A records.

  • Is there such thing as a portable database that runs easily OsX and Windows?

    - by Jean-Philippe Murray
    I need to make a small database for a project at school (not computer related at all, I'm indexing and categorizing paper documents of a research projet). The thing is that in september, my semester is over and other students will have to taker over the project (and so on, for every semester!), so I'd need something that would be free and OS agnostic (or at least OsX/Windows) so it would easily be given to the next students on the project. I was thinking about a WAMP running USB key that would have a MySQL / HTML interface, but it will become locked to the OS I choose first. LibreOffice and the likes will be an option in the end if I don't find anything truly portable. Anyone has a solution in mind?

  • Fabric and cygwin don't work with windows UNC paths

    - by tcoopman
    I have some strange problems with fabric deployment to Windows Server 2008r2. The thing I try to accomplish is to copy some files to a shared folder with a fabric script (this script does a lot of other things too, but only this step gives me problems). This is the problem: When I try to access a UNC(Universal Naming convention) path I always get access denied kind of answers if I run the script in fabric. When I run the command in an ssh prompt (same user) it works fine. Examples: cmd: robocopy f:/.... //share result: in ssh this works fine, in fabric I get "Logon failure: the user has not been granted the requested logon type aat this computer." cmd: cd //share result: in ssh this works fine, in fabric I get "//share: Not a directory" Further information: uname -a and whoami return exact the same thing in fabric and ssh. I also tried things like mount, net use, but these commands all have kind of the same problem.

  • Can't run Ubuntu from disc

    - by alex
    When I place the boot CD in my CD drive and boot from it, I get the Ubuntu menu. I have these options Try Ubuntu without any change to your computer Install Ubuntu Check disc for defects Test memory Boot from first hard disk I can use the cursor keys to select them, and I can push F1 for help etc. However, I can not select an option. I've highlighted the first and tried enter, space bar etc. I do have a KVM, so I plugged in a 2nd USB keyboard and tried it but no go either. I can push escape and then got to the prompt. Am I doing something wrong?

  • Removed Java replaced with newest "Sun Java", disc won't boot, and won't let me re-install grub using boot repair disc

    - by Al Rowe
    Had a minor problem with my Stock market platform. Set-up screen would freeze program. Called their tech support, got their "Linux guy", who advised remove all Java and replace, not with synaptic version, but newest Sun Java. After removing, computer auto rebooted, and went to blue mem-test screen. Showed no errors, but couldn't get back in. Tried two versions of boot repair disc from iso (checked md5sum, showed good.), but fix aborted, giving apt-error detected. Opened a terminal and typed (or copy/paste): sudo chroot "/mnt/boot-sav/sda1" apt-get -f install. My system is Ubuntu 12.04. Had a few very minor issues from install, all fixed. Also added some of my favorite gnome tricks just to make life easier, but none that could have caused this. Added script to add shortcuts to desktop, open terminal in any menu from inside it, access root terminal, etc. System was firewalled and using avast antivirus (o.k., I'm paranoid. Used to do Windows sys-op and security.) But relative newbie to Linux.

  • Visual Studio 2005 SP1 refuses to install in Windows 7

    - by JesperE
    I'm trying to install Visual Studio 2005 in Windows 7. When attempting to start, Windows 7 complains that VS2005 is incompatible with Windows 7 and offers me to search online for a solution. It comes up with a link to VS2005 SP1 for Vista and Windows 7, but when I download it (VS80sp1-KB932232-X86-ENU.exe) and try to run it, it refuses to install saying that The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch.

  • Java Applet Tower Defence Game needs tweeking

    - by Ephiras
    Hello :) i have made a tower defence Game for my computer science class as one of my major projects, but have encountered some rather fatal roadblocks. here they are creating a menu screen (class Menu) that can set the total number of enimies, the max number of towers, starting money and the map. i tried creating a constructor in my Main class that sets all the values to whatever the Menu class passes in. I want the Menu screen to close after a difficulty has been selected and the main class to begin. Another problem i would really like some help with is instead of having to write entire arrays i would like to create a small segment of code that runs through an entire picture and sets up an array based on that pixels color.this way i can have multiple levels just dragged into a level folder and have the program read through them. users can even create their own. so a 1 if its yellow, a two if blue and a 3 if purple, then everything else = 0; you can download all the classes and code uif you'd like here sorry about having to redirect you but i wasn't sure how to efficently add a code spoiler. help is greatly appreciated

  • USB port not recognising mouse on first bootup

    - by Pacifika
    On a computer here when first powered on the USB wired mouse is not recognised. The light under the mouse is not lit up. Other usb hub's and keyboards work fine. Disconnecting it and reconnecting it fixes the issue, even after a restart - after the pc is switched off for a length of time (for example overnight) the problem reappears. I swapped the mouse, updated the bios and installed updated intellimouse drivers, turned of power saving on the usb ports. Any ideas?

  • Analyzing Memory Usage: Java vs C++ Negligible?

    - by Anthony
    How does the memory usage of an integer object written in Java compare\contrast with the memory usage of a integer object written in C++? Is the difference negligible? No difference? A big difference? I'm guessing it's the same because an int is an int regardless of the language (?) The reason why I asked this is because I was reading about the importance of knowing when a program's memory requirements will prevent the programmer from solving a given problem. What fascinated me is the amount of memory required for creating a single Java object. Take for example, an integer object. Correct me if I'm wrong but a Java integer object requires 24 bytes of memory: 4 bytes for its int instance variable 16 bytes of overhead (reference to the object's class, garbage collection info & synchronization info) 4 bytes of padding As another example, a Java array (which is implemented as an object) requires 48+bytes: 24 bytes of header info 16 bytes of object overhead 4 bytes for length 4 bytes for padding plus the memory needed to store the values How do these memory usages compare with the same code written in C++? I used to be oblivious about the memory usage of the C++ and Java programs I wrote, but now that I'm beginning to learn about algorithms, I'm having a greater appreciation for the computer's resources.

  • Power cut during Ubuntu upgrade to 10.04 - boots to command line, apt-get and dpkg do not work.

    - by Macha
    I was upgrading Ubuntu to 10.04, when a tripswitch tripped, cutting power to the computer. When it was restarted, it booted into a command line prompt. Google tells me to try: sudo dpkg --configure -a This gets me a lot of output that ends with a list of packages. I can't tell you what the output is, as piping the output to more/less does not work (still just all scrolls by and moves to next prompt), and redirecting it to a file just results in an empty file. Google also suggested: sudo apt-get install -f This also didn't work. Is a fresh install the only solution at this point?

  • Tracking down random BSOD on windows 7

    - by pehrs
    I have gotten a computer running windows 7 handed to me that randomly, several times a day, bsods with a PAGE_FAULT_IN_NONPAGED_AREA (50) or WHEA_UNCORRECTABLE_ERROR (124). Crashes happens regardless of load. I am running out of ideas for how to track this down. Analyzing the minidumps shows the crash to be in ntkrnlmp.exe/WMIADAP.exe System has plenty of power (600w) Ram checks out fine using memtest86+ over a weekend. System is clean inside. No dust build up. Temperatures stay low. As far as I know (and reliability history shows) no new drivers were installed for several months before the problems started. All drivers are now up to date. sfc /scannow reports the system as clean. CHKDSK reports the disks as clean Removing the AV (Avast) has no effect. Any more things that should be tried on windows 7 before I start replacing the hardware?

  • Have 3 Monitors Display the same thing? (WinXP)

    - by Drew Tenenbaum
    I have a setup in which there is a Computer running windows XP, with 3 monitors plugged into it, with a "Matrox Millennium P750" Graphics card. What I want is to enable mirroring of ALL THREE MONITORS, meaning I want all the monitors to display the same image. In Matrox Powerdesk, it does not have an option to do this, and I'm pretty sure that Windows XP does not support it nativley. I really should only need some software/drivers, right? What can i do to display the same thing on 3 screens?

  • ubuntu 12.10/linux mint 14 ssh-copy-id doesn't work and returns Ambiguous output redirect

    - by Marc
    I recently got a new computer and I'm trying to use ssh-copy-id to put my keys on another server so I can login without password. but when I try ssh-copy-id -i ~/.ssh/id_rsa.pub user@server and after inputting the correct password it returns Ambiguous output redirect. There are no other messages after that. I thought it was maybe just Ubuntu 12.10 so I installed Linux Mint 14 and sure enough exact same thing happens. I've tried removing authorized_keys from the remote server but that didn't change anything.

  • Setting up NIS/NFS on Mac OS 10.6

    - by evan
    We have an Ubuntu NIS/NFS server at work and we recently got a few new iMacs. Is there a way to set them up so they can use the linux user accounts and mount the shared nfs files? Are there any guides on how to do this? I've been googling with no success. I tried getting NFS to work by connecting to the server via the Disk Utility but after I run 'sudo automount' from the command line and ls the directory I tried to mount it to (Volumes/nfs) it gives a permissions error. If there isn't a way to do this, anyone know of any not to complicated ways to share user accounts and files between mac and linux computers (and even hypothetically a windows computer one day?) I know its kind a of huge question, but I'll greatly appreciate any advice on the topic. Thanks!

  • Boot from external usb hdd won't work in 12.04

    - by Ben Andersen
    I've been running 10.04 on an external USB HDD without problems for years. I installed 12.04 on an external USB HDD and it worked until I upgraded to all the new packages. But after that it wouldn't boot. I just got into the grub prompt. So then I tried installing on the disk inside the computer and that worked fine. But when I take it out and use it as an external USB HDD I just get: error: hd0 out of disk. grub rescue> How can I fix this? So why do I want this you might wonder? Well I have a laptop at home and a somewhat similar at work. And I just move the disk between them and don't have to move a heavy laptop. So I really hope I can continue doing this with 12.04! The old disk is only 80Gb but the new one is 320Gb (7200rpm Toshiba). I'm using 12.04 on a 64Gb SSD as an external drive and it warns about out of disk but it boots anyway most of the times.

  • how can I discover what keys are being sent when I press a mouse button?

    - by jcollum
    I'd like to map my Logitech MX Revolution keys in Visual Studio. More importantly, I'd like to do it without installing any software. Is this possible? I specifically want to map the two side buttons to View.NavigateBackward and View.NavigateForward. But I'm not sure what those keys are mapped to right now. I thought they were mapped to Ctrl-Tab and Shift-Ctrl-Tab, since they seem to behave that way in Notepad++, but that isn't working in VS. I'm on the work computer, which means 2 problems: I'm in Windows XP and installing software is frowned upon/monitored.
