• hp XW8000 work station power supply

  - by user281745

  My power supply went up in the XW8000 and I bought a new corsair cx500. I installed it but when I hook it up and I turn the computer on I get a beeping noise from the computer. I looked at the old power supply and the new power supply. The only difference is that the new power supply has 500 watts and the old one is 450 watts and the old PSU has a brown wire and the new power supply has 2 orange wires at the end. I found out that it is a sense wire that is in a different location so I was wondering how do I fix this problem.

• Wubi downloaded and installed 64bit 12.10 on my 32bit netbook

  - by Troy

  I downloaded the Wubi installer on my atom N450 netbook. When I started up Ubuntu I got an error that read failed to change the mode of /ect/passwd- to 0600. Then while it booted it froze and several strange characters filled the screen. Finally it loaded it ran pretty slow, and I could connect to my router, but not to the internet. Ping 8.8.8.8 showed no server found. So I checked the about computer and it said I was running the 64 bit installation. Now I know that my computer has a low power 32 bit chip and even the Ubuntu iso download suggested a 32 bit installation. So I went to double check and see if I just missed the option for a 32 bit Wubi install and I did not. There was no option. Is there any way to download a 32 bit version of 12.10 through the Wubi?

• Mouse permanently stuck on left side of screen

  - by Alex

  One of my two monitors is died, so while my computer was turned off I unplugged the dead monitor then turned my computer back on. When I got to the log in page I typed my password and got to the desktop my mouse was stuck to the left edge of the screen. I can move it up and down, and left and right click, but it won't come off the edge. I tried switching the monitor cable to the other slot to see if that would make a difference but nothing changed. If it makes a difference, I'm using Kubuntu.

• Xubuntu keeps loading on install with usb stick

  - by mattyh88

  I'm trying to install Xubuntu on my computer. I've followed a guide to create a USB bootable drive. I've inserted the USB stick and started the computer. I can see Xubuntu loading and after a minute or 2 it shows me a screen asking me if I'd like to use the live version or if I'd like to install. I choose install. Then on the next screen I select English as language. When I click continue, Xubuntu just keeps loading. It doesn't really freeze as I can still quit and move the cursor. When I clicked quit, I see the live version and all is working just fine. I can browse the internet, etc. What could be wrong?

• Why is my laptop so sluggish? Or Damn You Facebook and Twitter! Or All Hail Chrome!

  - by John Conwell

  In the past three weeks, I've noticed that my laptop (dual core 2.1GHz, 2Gb RAM) has become amazingly sluggish.  I only uses for communications and data lookup workflows, so the slowness was tolerable.  But today I finally got fed up with the suckyness and decided to get to the root of the problem (I do have strong performance roots after all). It actually didn't take all that long to figure it out.  About a year ago I converted to Google Chrome (away from FireFox).  One of the great tools Chrome has is a "Task Manager" tool, that gives you Windows Task Manager like details for all the tabs open in the browser (Shift + Esc).  Since every tab runs in its own process, its easy from Task Manager (both Windows or Chrome) to identify and kill a single performance offending tab.  This is unlike IE, where you only get aggregate data about all tabs open.  Anyway, I digress.  Today my laptop sucked.  Windows Task Manager told me that I had two memory hogging Chrome tabs, but couldn't tell me which web page those tabs are showing.  Enter Chrome Task Manager which tells you the page title, along with CPU, memory and network utilization of each tab.  Enter my amazement.  Turns out Facebook was using just shy of half a Gb of RAM.  Half a Gigabyte!  That's 512 Megabytes!524,288 Kilobytes! 536,870,912 Bytes!  Or 4,294,967,296 Bits!  In other words, that's a frackin boat load of memory.  Now consider that Facebook is running on pretty much 96.3% (statistics based on absolutely nothing) of every house hold desktop, laptop, netbook, and mobile device in America, that is pretty horrific! And I wasn't playing any Facebook games like FarmWars or MafiaVille.  I just had my normal, default home page up showing me who just had breakfast, or just got finished with their morning run. I'm sorry...let me say that again...HALF A GIG OF RAM!  That is just unforgivable. I can just see my mom calling me up:  Mom: "John...I think I need a new computer.  Mine is really slow these days" John: "What do you have running?" Mom: "Oh, just Facebook" John: "Ok, close Facebook and tell me how fast your computer feels" Mom: "Well...I don't know how fast it is.  All I do is use Facebook" John: "Ok Mom, I'll send you a new computer by Tuesday" Oh yea...and the other offending web page?  It was Twitter, using a quarter of a Gigabyte. God I love social networks!

• TFS 2008 to TFS 2010 moves and some issues

  - by Enrique Lima

  There have been many things going on this year around TFS.  Most of them had to do with migrations (I don’t call them upgrades for the most part since it involved new hardware and such).  Many were implementations using the Conchango SfTS template (now EMC). But there were others that were CMMI or Agile 4.0. Everything would move just fine, no issues.  That was until you attempted to run Test Case Management or run the last configuration steps for Lab Management. There is an error that states a project is not ready to run or integrate with Test or Lab Management.  And while there was some documentation on how to adjust and update the Agile WITs to work with it, there was still some disconnect to making it work with CMMI. Now there is a great post on how to run the “fix” from end to end. Check the post here:  TFS 2010: Enable Test Case Management for upgraded Team Projects

• Choppy/unresponsive keyboard and mouse pointer until suspend

  - by Stefan Thyberg

  I had a problem where my mouse and keyboard would be choppy, the mouse pointer would work at 1-2 fps and the keyboard would keep missing letters as I was typing them. Since they were both USB I suspected there was a problem there immediately. Whenever I got this problem I would suspend the computer and start it again and the problem would be gone. The problem started appearing when I plugged the mouse and keyboard directly into the computer rather than the USB hub in the screen. I'm using a Logitech UltraX Flat and a Razer Lachesis, but I'm not sure if that matters.

• Ubuntu will not start due to full partitions

  - by mike

  I left my computer downloading all the night and I did download 35 GB of movies (legal ...). I restarted the computed in the morning then I booted in my encrypted Windows partition for my work. I have left my computer downloading 35GB of files and when I restarted in the morning, I booted Windows. When I tried to access Ubuntu, it failed to boot and in low-graphic mode told me that it won't boot because the partition is full. I tried rescue and it reported 0 MB free. I also cannot delete files with sudo rm as all are impossible due to a read-only file system. I can mount it in Windows but there is a "write protection" there, also. Should I try a live USB?

• What do you think about gems and eggs? Alternatives?

  - by Juanlu001

  I've read recently some criticism (see 1, 2, 3) about the packaging distribution system of two popular programming languages: Ruby gems and Python eggs. The most important argument stated against them is that they replace the system package manager (in case there is one, as in every Linux distribution), which makes eggs and gems difficult to track, code difficult to patch, and so on. Are actually eggs and gems right? In case not, are there any alternatives to distributing Python or Ruby modules? Should developers focus on taking advantage of package manager (apt-get, pacman, ...) capabilities?

• How to obtain a list of installed packages based on a backup?

  - by ujjain

  I have made a backup of my entire computer and I reinstalled the OS right now. I know I should have listed dpkg -l to obtain a list of packages, but I have not done so. I only made a tarball of the entire disk. I wonder how I can find a list of packages based on this data. I would like to have the same packages installed that I had on my previous set-up. But there seems no longer a way to gain a list of packages, since I already reinstalled Ubuntu on the computer and only have the tarball back-up.

• Small hiccup with VMware Player after upgrading to Ubuntu 12.04

  The upgrade process Finally, it was time to upgrade to a new LTS version of Ubuntu - 12.04 aka Precise Pangolin. I scheduled the weekend for this task and despite the nickname of Mauritius (Cyber Island) it took roughly 6 hours to download nearly 2.400 packages. No problem in general, as I have spare machines to work on, and it was weekend anyway. All went very smooth and only a few packages required manual attention due to local modifications in the configuration. With the new kernel 3.2.0-24 it was necessary to reboot the system and compared to the last upgrade, I got my graphical login as expected. Compilation of VMware Player 4.x fails A quick test on the installed applications, Firefox, Thunderbird, Chromium, Skype, CrossOver, etc. reveils that everything is fine in general. Firing up VMware Player displays the known kernel mod dialog that requires to compile the modules for the newly booted kernel. Usually, this isn't a big issue but this time I was confronted with the situation that vmnet didn't compile as expected ("Failed to compile module vmnet"). Luckily, this issue is already well-known, even though with "Failed to compile module vmmon" as general reason but nevertheless it was very easy and quick to find the solution to this problem. In VMware Communities there are several forum threads related to this topic and VMware provides the necessary patch file for Workstation 8.0.2 and Player 4.0.2. In case that you are still on Workstation 7.x or Player 3.x there is another patch file available. After download extract the file like so: tar -xzvf vmware802fixlinux320.tar.gz and run the patch script as super-user: sudo ./patch-modules_3.2.0.sh This will alter the existing installation and source files of VMware Player on your machine. As last step, which isn't described in many other resources, you have to restart the vmware service, or for the heart-fainted, just reboot your system: sudo service vmware restart This will load the newly created kernel modules into your userspace, and after that VMware Player will start as usual. Summary Upgrading any derivate of Ubuntu, in my case Xubuntu, is quick and easy done but it might hold some surprises from time to time. Nonetheless, it is absolutely worthy to go for it. Currently, this patch for VMware is the only obstacle I had to face so far and my system feels and looks better than before. Happy upgrade! Resources I used the following links based on Google search results: http://communities.vmware.com/message/1902218#1902218http://weltall.heliohost.org/wordpress/2012/01/26/vmware-workstation-8-0-2-player-4-0-2-fix-for-linux-kernel-3-2-and-3-3/ Update on VMware Player 4.0.3 Please continue to read on my follow-up article in case that you upgraded either VMware Workstation 8.0.3 or VMware Player 4.0.3.

• Ubuntu 14.04 doesn't detect my discrete GPU

  - by user258887

  I recently purchased a laptop with an Nvidia GeForce 860m, and have installed Ubuntu 14.04. On my old laptop I had 12.04, which automatically filled Additional Drivers with Nvidia drivers. But on this computer, the only thing in Additional Drivers is Qualcomm. So I manually installed Nvidia, but X Server Settings doesn't seem to detect any GPU... lspci | grep VGA reports only my integrated Intel GPU, but lspci -v reports many things, including the Nvidia GPU: 01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 860M] (rev a2) Subsystem: ASUSTeK Computer Inc. Device 157d Flags: fast devsel, IRQ 16 Memory at ec000000 (32-bit, non-prefetchable) [size=16M] Memory at c0000000 (64-bit, prefetchable) [size=256M] Memory at d0000000 (64-bit, prefetchable) [size=32M] I/O ports at e000 [size=128] Expansion ROM at ed000000 [disabled] [size=512K] Capabilities: access denied Don't know what any of that means. Not sure if it's supposed to say 'access denied'... I need my GPU to do CUDA and OpenGL programming. What else can I do to figure out why this isn't working?

• How to make a great functional specification

  - by sfrj

  I am going to start a little side project very soon, but this time i want to do not just the little UML domain model and case diagrams i often do before programming, i thought about making a full functional specification. Is there anybody that has experience writing functional specifications that could recommend me what i need to add to it? How would be the best way to start preparing it? Here i will write down the topics that i think are more relevant: Purpose Functional Overview Context Diagram Critical Project Success Factors Scope (In & Out) Assumptions Actors (Data Sources, System Actors) Use Case Diagram Process Flow Diagram Activity Diagram Security Requirements Performance Requirements Special Requirements Business Rules Domain Model (Data model) Flow Scenarios (Success, alternate…) Time Schedule (Task Management) Goals System Requirements Expected Expenses What do you think about those topics? Shall i add something else? or maybe remove something?

• Ubuntu 12.04 wired ethernet not working and wireless not working, How do I fix it?

  - by Eloy

  I am new to ubuntu. I recently installed the latest ubuntu for desktop from http://www.ubuntu.com/download. I was very excited to start using ubuntu until I booted the computer and saw that i couldn't connect to the internet at all. I have spent hours trying to figure this out. I keep running into people suggesting installing drivers etc. I have tried about everything and nothing seems to work. I have the ethernet cable connected to the computer but it doesn't recognize it. I ran the following: lspci | grep -i eth and I get this 09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet PCI Express (rev 02) Any help would be much appreciated. I am kind of bummed I have spent all this time tyring to get the internet to work and haven't even gotten to use the power of ubuntu Update copied from comment: Changing the Ethernet cable to a different one fixed the problem.

• Sound card stop responding

  - by Merianos Nikos

  A few days ago I installed the latest version of Ubuntu in a computer of mine, that it has installed the "Sound Blaster Audigy 2ZS". After the installation and up to yesterday everything was excelent. Yesterday I installed the latest Ubuntu updates and today I had several issues. First the mouse was not responed as should be, but after restarted my computer everything was fine with mouse. Next was my sound card. For now I do not have sound at all :( I don't really know what's wrong. Does anybody has any idea on how to solve that issue, or from where to start, to find a solution ? If there is no any available solution for that issue, can I remove the latest updates that installed yesterday ? Kind regards Merianos Nikos

• Event Driven Behavior Tree: deterministic traversal order with parallel

  - by Heisenbug

  I've studied several articles and listen some talks about behavior trees (mostly the resources available on AIGameDev by Alex J. Champandard). I'm particularly interested on event driven behavior trees, but I have still some doubts on how to implement them correctly using a scheduler. Just a quick recap: Standard Behavior Tree Each execution tick the tree is traversed from the root in depth-first order The execution order is implicitly expressed by the tree structure. So in the case of behaviors parented to a parallel node, even if both children are executed during the same traversing, the first leaf is always evaluated first. Event Driven BT During the first traversal the nodes (tasks) are enqueued using a scheduler which is responsible for updating only running ones every update The first traversal implicitly produce a depth-first ordered queue in the scheduler Non leaf nodes stays suspended mostly of the time. When a leaf node terminate(either with success or fail status) the parent (observer) is waked up allowing the tree traversing to continue and new tasks will be enqueued in the scheduler Without parallel nodes in the tree there will be up to 1 task running in the scheduler Without parallel nodes, the tasks in the queue(excluding dynamic priority implementation) will be always ordered in a depth-first order (is this right?) Now, from what is my understanding of a possible implementation, there are 2 requirements I think must be respected(I'm not sure though): Now, some requirements I think needs to be guaranteed by a correct implementation are: The result of the traversing should be independent from which implementation strategy is used. The traversing result must be deterministic. I'm struggling trying to guarantee both in the case of parallel nodes. Here's an example: Parallel_1 -->Sequence_1 ---->leaf_A ---->leaf_B -->leaf_C Considering a FIFO policy of the scheduler, before leaf_A node terminates the tasks in the scheduler are: P1(suspended),S1(suspended),leaf_A(running),leaf_C(running) When leaf_A terminate leaf_B will be scheduled (at the end of the queue), so the queue will become: P1(suspended),S1(suspended),leaf_C(running),leaf_B(running) In this case leaf_B will be executed after leaf_C at every update, meanwhile with a non event-driven traversing from the root node, the leaf_B will always be evaluated before leaf_A. So I have a couple of question: do I have understand correctly how event driven BT work? How can I guarantee the depth first order is respected with such an implementation? is this a common issue or am I missing something?

• Flashing task bar(firefox) in lxde panel and ubuntu internal error

  - by arroy_0209

  I have upgraded from ubuntu10.04 to 12.04 and installed lxde. The panel is now customized according to my convenience. The problem is there was a default checked option for "Flash when there is any window requiring attention" in Task bar(window list) and now when I run firefox, at times the concerned bar in the panel window list starts flashing but it is not clear exactly why at that moment firefox requires my attention. Normally this happens after I download some files (pdf files) and keep using firefox. The only solution I have found is to quit firefox and even after that I receive this message "Sorry, ubuntu12.04 has experienced an internal error. If you notice further problems, try restarting the computer." As usual I report the detailed message to ubuntu as suggested and finally restart the computer. So there are two problems, first, exactly why firefox needs my attention at times and second, why immediately after this, ubuntu experiences an internal error. Please suggest what I should do.

• Monitor displays "No VGA signal" "Check DVI cable" after installing motherboard drivers

  - by user1604220

  I bought computer with all of the needed parts, got everything sorted out, installed windows 7 but my CD-ROM doesn't fit my motherboard. So I had to download the driver manually and install it using USB disc. My motherboard: ECS elitegroup H61H2-M2, I downloaded it's drivers, installed the BIOS map or something, and then the computer forced a reboot after it was complete, after the reboot my monitor just stopped working and displayed No VGA signal, No DVI cable I think I've just installed the wrong driver, well but how can I sort it out? This is the driver I installed. On the book, it tells me to install the drivers, without the driver it won't see the Internet connection cable. I'm 100% sure there is nothing wrong with the monitor or it's cables. it stopped working exactly after the reboot after the installation.

• Crontab opens as blank page, cannot save

  - by Sarah

  I am really not familiar with linux, and only started using it recently, so be patient with me. I am trying to control a camera on regular intervals through a script that is called upon in the crontab. When I start up the computer, I can open crontab, edit and save, and everything is executed correctly. However, I can never open crontab a second time, unless I restart the computer first. If I type crontab -e, I get a blank page, located in the /tmp directory. I can enter my commands in there, but cannot save it. I don't know if this is relevant, but when I try sudo crontab -e, I get something like "no cron installed for root". Any help is really appreciated! Sarah

• System doesn't boot when ubuntu is installed on an SSD

  - by Caetano Nichnich Nunes

  I've recently discovered Ubuntu and decided to give it a try. I am using a Samsung Series 5 p530u3c-ad1 which comes with a 24gb SSD and a ~500gb HDD, My intention is to set the system files to the ssd and the rest to the HDD. The system works fine if I do a direct install using only the HDD, but if I try using the SSD for the system files the computer doesn't boot-up, I do not know if the SSD is being recognized by the computer, I think so because I could install Ubuntu on it, but it doesn't appear on the boot order or the boot menu. I read some posts and tried using boot-repair which pointed me not to forget to set my system to boot from my SSD, unfortunately I cannot because of the issues mentioned above. Thanks for your time.

• gnome-file-share-properties doesn't work

  - by Riccardo Magrini

  I've configured gnome-file-share-properties on all my Ubuntu's PC for sharing the directory Public to each other. I following some guide found on Internet for the configuration of it, all explain the same procedure but in my case I don't see any Public directory shared with the PC. Following this link http://library.gnome.org/users/gnome-user-share/stable/gnome-user-share-getting-started.html.en I'd see the directory Public plus the name of PC that shares its directory on Nautilus Places. In my case I don't see anything, therefore on the Network place see all the machines 'n if I try to click on one receive this: "DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)" note: I don't want to use Samba because I've all Ubuntu PC, and the firewall is disabled on all PC.

• How to remove Ubunto from boot screen?

  - by Alaa M.

  I tried to install Ubuntu 14.04 on my Windows 8, and in the installation wizard I chose "Help me boot from CD". Now I have something like this when I restart the computer: http://i.stack.imgur.com/HxDQr.png If I click Ubuntu I get an error about a missing file (wubildr.mbr). I found a solution here. But that's not my concern now. I don't know if that means I have Ubuntu installed on my computer now or not, but I wanna delete it from the boot screen. I figured that I need to delete its partition, so I went to Disk Management and found the following: http://i.stack.imgur.com/W0oP4.png My question is: which one should I delete?
