• No boot record when installing 13.04 from USB on WinXP

  - by Phil Leslie

  I'm replacing WinXP with 13.04 on an older PC using wubi.exe on a USB stick. I had no problem changing the BIOS on another system that was a bit newer but when I change the settings on the older PC to boot from USB, I get a DOS message saying "Searching for boot record...Not found" & asked to try again. I don't have the ability to boot from a live CD so is there a reason why I can boot from a USB on a newer computer but can't from an older one? Both have options to choose to boot from USB, but the older one can find no boot record. The system was built on 12/13/01 by American Megatrends. Since I don't have enough "reputation points" to post the screen shot image, you can see it at http://img.photobucket.com/albums/v633/boonevillephil/1029131748-00.jpg.

• Ubuntu won't run

  - by Cody

  So I just installed it last night, the latest version. I did a fresh install. When I woke this morning I turn on the computer and login. It goes to a black screen with two thick with/multicolored lines towards the bottom and freezes. I then must shut down the tower. I have only been able to run the 'Ubuntu 2D' option. I am new to this all and need some help. Also when I am using terminal it wants me to enter my password, but it says its incorrect. Is there anyway so I don't need to enter my password when I use it and also when I install or remove something? Many thanks would be helpful. What is Ubuntu 2D?

• Network does not connect at boot

  - by Daniel Svozil

  I am on Ubuntu 12.04, fresh install. When I boot a machine, the boot screen says Connecting to network, later it is changed to something like Did not connect, trying for another 60s. However, the network does not connect at the boot. But I can then log in without a network connection, and if I start a network manager service manually from the terminal (sudo service network-manager start), the network is connected without any problems. Please, does anybody know where the problem could be? I don't want to wait more than two minutes every computer restart :-). I am new to Ubuntu (and also to upstart) so I am a bit lost. There is no /var/log/messages, in dmesg I found this record, though it may not be related: init: network-interface (eth1) pre-start process (492) terminated with status 1 init: network-interface (eth1) post-stop process (548) terminated with status 1 Thanks Daniel

• 12.04 on Pentium Dual Core with 1GB or ram running slow

  - by Alex

  hey i have a Lenovo Thinkpad Laptop with Ubuntu 12.04 installed. It runs slow. I tried "System profiler and Benchmark" to test the computer. but the application quits and closes after the first few benchmark test. before it even gets to the other tests. So i tried "Hardinfo" that installed on the Puppy Linux live cd. that did the same thing (the apps look just a like). the memory usage isnt the problem on this pc. its the cpu processes. just running the "system profiler" app that comes with ubuntu uses about 34% on each core, default with nothing running its 5-10% on each core. i cant really find what the deal is other than that ubuntu is a cpu hog. so im testing unity2D at the moment to see how it goes. if you have any other suggestions, feel free to answer this question. thanks

• Cisco AnyConnect VPN Client broke my internet

  - by user137864

  I was using the AnyConnect client when it froze and I had to do a hard reboot of my computer. Now I can't connect to the internet at all, with or without VPN. The Network Connections manager seems to think I have a wired and wireless connection without a problem, but I can't go online. I have tried using /etc/init.d/networking restart and it even says it is "ok" with no luck. I am guessing I need to clear some settings somewhere and restart a service, but I am not sure what. Thanks!

• Why does qt-creator need to connect to google-analytics?

  - by Nanda

  I just installed qt-creator to work on non-qt C++ projects. The installed version is 2.5.0 (Based on Qt 4.8.2 32-bit) If I click on any of these pages: I get this error: I realized that /etc/hosts file has the following entry: 127.0.0.1 www.google-analytics.com I don't want to remove the entry from the hosts file because it's always been there along with thousands of other similar adservices/porn/malware addresses. I do not intend to say that qt-creator is looking to create problems in my computer, but I am genuinely interested to know why qt-creator needs to connect to google-analytics? Can this be disabled and qt-creator can still be functional?

• How should I study programming languages?

  - by gcc

  I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter).

• Cannot sleep/standby in Ubuntu 12.04

  - by mstaessen

  Yesterday, I installed Ubuntu 12.04 Desktop i386 on my netbook (HP Mini 311c). I am unable to use the sleep mode. When I press the suspend button (or do sudo pm-suspend), the screen flickers but the computer does not power off. Even worse, the screen comes back up and I'm back where I left off. Hibernating does work (although it is not available in Power Management). I have to use pm-hibernate to make that work. I'm using the 3.2.0.20 kernel and Gnome 3.3.92 (Unity, especially compiz, is a resource hog). Before Ubuntu 12.04, I was using Mint Linux 12 with the 3.0 kernel and everything worked fine back then. Any help is much appreciated because this is driving me crazy.

• Elantech trackpad being identified as a logitech wheel mouse.

  - by Nathan Cox

  I recently purchased a Samsung RF510 laptop computer, which I absolutely love. However, upon installing Ubuntu 10.10 onto it I couldn't get the trackpad to function properly. It worked as a basic mouse (point and click) but had no functionality for edge scrolling or any of the multitouch settings the trackpad is capable of. After doing a lot of research I discovered the reason is a known issue where the Ubuntu kernel will improperly detect an Elantech trackpad as a logitech PS/2 wheel mouse, and as such will gain none of the functionality that seems to be coded for synaptics trackpads. The question I have is: does anyone know a way to get this working properly? This is my first time trying to run Ubuntu on a laptop (actually, it's my first laptop in the last 12 years) and I'm finding the experience to be intolerable without the basic scrolling/zooming/etc I've been used to using for as long as I can remember.

• The Best How-To Geek Articles for June 2011

  - by Asian Angel

  June has been a busy month here at How-To Geek where we covered topics like cleaning keyboards, what to do when your e-mail has been compromised, creating high resolution Windows 7 icons, and more. Join us as we look back at the most popular articles from this past month. Note: Articles are listed as #10 through #1. What You Said: How Do You Keep Notes? Note taking applications have grown increasingly sophisticated. Historically, when people took notes on a computer they simply used the word processor or text editor installed on it and left it at that—mostly because there were few widely available alternatives. While many people still use simple txt files for their note taking needs an entire ecosystem of note taking apps exists now—thanks, in large part, to the rise of widespread internet access and easy synchronization.How To Encrypt Your Cloud-Based Drive with BoxcryptorHTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)

• Graphic card for parallel programming vs traditional methods

  - by Sambatyon

  With a simple search in amazon one can see that the modern approach for parallel programming is to use your graphic card. However I am still a little bit skeptical about it. My last computer has an 8 core CPU which I need is enough for basic all my parallel needs, if I need more I will probably use MPI through a network using my old machines. All in all, Why and/or when should I use CUDA or another method which uses my graphic card instead of traditional methods like pthreads, java threads, boost threads or the new C++ 11 threads? What about using processes?

• What triggered the popularity of lambda functions in modern programming languages?

  - by Giorgio

  In the last few years anonymous functions (AKA lambda functions) have become a very popular language construct and almost every major / mainstream programming language has introduced them or is planned to introduce them in an upcoming revision of the standard. Yet, anonymous functions are a very old and very well-known concept in Mathematics and Computer Science (invented by the mathematician Alonzo Church around 1936, and used by the Lisp programming language since 1958, see e.g. here). So why didn't today's mainstream programming languages (many of which originated 15 to 20 years ago) support lambda functions from the very beginning and only introduced them later? And what triggered the massive adoption of anonymous functions in the last few years? Is there some specific event, new requirement or programming technique that started this phenomenon?

• All video players display black screen.

  - by Dennis

  I'm working in 10.04 Lucid. All my video players (Movie Player and VLC) and the preview windows in editors (OpenShot and Pitivi) will only display a black screen when playing a video. The sound is fine and the videos work fine on other computers. I have tried multiple formats from varying sources .MOV taken from old ffmpeg projects, .AVI straight from a camera, .MP4 using h.264 from OpenShot on another system, .OGV from a gtk-recordmydesktop session on this very computer. I even get a pure black screen in the viewer when starting a remote session in VNC. This box has a GeForce 8400 GS using the Nvidia drivers in case it may be a card problem or setting.

• How do I disable changing proxy settings?

  - by gap

  I've got several machines, running 14.04.1, for kids to access. Each machine has accounts for each kid, as well accounts for several adults. Although I've set a system wide proxy use policy, it doesn't get used by Chrome. Instead, I had to log into each kids account and set a proxy use policy, pointing to tinyproxy/dansguardian, for safe internet access. The problem is that, should the kids get an ounce of computer savvy, they'll figure out that they can launch the proxy settings config panel from Unity, then change the proxy settings to None, and completely bypass the "safe" internet scheme I've setup. Can anyone tell me how I can disable those user accounts from being able to modify their proxy settings (not the "system wide" ones... those arent used.. this is the per-user settings). Thanks

• How to create a use case diagram for board game played on PC

  - by user970696

  I'm struggling with a task as I was given to practice UML and use cases. The problem is that I should model computer version of a board game so I am unsure about a few things. obviously it does not matter if you play against the PC or another player, the actions are the same. The game is simply like tic tac toe. E.g. Actor Player ---(Place a diamond)-----include----(Check for a row)---include--(Swap players) But the game is played on the PC, so is Check for row really a use case? And the same with Swap players? Because the system would do that. On the other hand, if it was not, how could I continue?

• How do I fool 12.10 to think it uses Unity2d in order to get the resolution my screen can use?

  - by Konstapel Kask

  On a laptop (model older) I have two screens (one built in, one external). I wish to use them both at the same time, but the settings app complains: Requested size (2944, 1080) exceeds 3D hardware limit (2048, 2048). You must either rearrange the displays so that they fit within a (2048, 2048) square or select the Ubuntu 2D session at login. The problem though, Unity 2D has been discontinued. I have forced Ubuntu to render Unity in 2D mode (with the help of echo export UNITY_LOW_GFX_MODE=1 >> .xprofile in accordance to this askubuntu post. But the error message still remains. How can one get the resolution that my computer supports? Or, how can I assure Ubuntu that it truly does use a 2D session?

• Horible lag on Xubuntu media center setup

  - by William

  I am setting up a media center running Xubuntu 11.10 as a media center. It is using the XFCE desktop enviroment. I have the NVIDIA drivers installed from the Additional Drivers program, and uninstalled all but the esennitial software. The computer is a Dell Dimension 3000. You can view detailed technical specifications here. The graphics card installed is a Geforce 8400 GS. I have installed all updates through Update Manager. What can I do to fix the horrible lag? It makes watching TV impossible.I have uploaded two videos of the lag, here and here. The second one does not have sound because the sound stops playing on some channels that lag a lot. The TV card is a Hauppage 950q USB, and the TV recording program is Kaffiene. Please help me with this, I am trying to do this to show how great Ubuntu is to the rest of the family.

• How do I query the gvfs metadata for a specific attribute?

  - by Mathieu Comandon

  A nice feature in evince is that when you close the program and later reopen the same pdf, it automatically jumps to the page you were reading. The problem I have is that I often read ebooks on several computers and I have to find were I was on the last computer I was reading the pdf. I think syncing these bookmarks in UbuntuOne would be a killer feature for people like me who read pdfs on different computers. By investigating a bit, I found where evince was storing this data, it's in the gvfs metadata and it can be accessed for a particular document by typing gvfs-ls -a "metadata::evince::page" myEbook.pdf Rather that querying a particular file, I'd like to query the whole metadata file (located in ~/.local/share/gvfs-metadata/home for the home directory) for any file where this particular attribute is set to some value. The biggest issue is that gvfs metadata and stored in binary files and we all know it's not easy to get something out of a binary file. So, do you know any way to query the gvfs metadata for some attribute?

• My ASUS U32U with fresh Xubuntu install shows a black screen 50-80% of the startups

  - by Jona Ekenberg

  I have recently installed Ubuntu 12.10 with Xubuntu-package on my ASUS U32U notebook (Radeon HD 6320 GPU). The issue I have is that more often than not, after the GRUB-select screen I get a black screen, and three times total white lines (kind of) flashes very quickly (with maybe 5 seconds between each flash). I'm not even able to get to the login-screen (nor the Xubuntu loading screen). At first I thought it was simply me having installed something dumb or messed up some settings, but even after reformatting the partition and installing ubuntu again, the problem remains. Before I formatted it xfce4's window manager wouldn't start either, but it does now (when I am able to see anything). I can access the virual consoles (ctrl+alt+f1), but I can't see anything, but I've managed to shutdown the computer by using it (sudo shutdown -h now).

• Openmatics Revolutionizes Fleet Management with Standards-Based Vehicle Telematics Platform

  - by Michael Snow

  Openmatics s.r.o. was founded in 2010 as a subsidiary of ZF Friedrichshafen AG, a global player in driveline and chassis technology. Oracle Customer:  Openmatics s.r.o.Location:  Pilsen, Czech RepublicIndustry:  AutomotiveEmployees:  70 Its goal was to develop and operate a flexible, open telematics platform for automotive applications, which is independent from vehicle and component suppliers—recognizing that the fragmented telematics market was not meeting today’s fleet management needs. Openmatics provides a rich product portfolio, and customers can extend the platform, as required, to meet their needs. Partners and third-parties can develop their own applications using the Openmatics’ software development kit and can sell them via the Openmatics app shop.ZF Friedrichshafen AG is a global player in driveline and chassis technology. With 121 production companies and 650 service partners in 26 countries, ZF is among the top 10 largest automotive suppliers worldwide. Founded in 1915 to develop and produce transmissions for airships and vehicles, the group’s product offerings now include transmissions and steering systems as well as chassis components and complete axle systems and modules.  A word from Openmatics s.r.o.  “Oracle WebCenter Portal, together with the underlying Oracle Application Development Framework, provided the fundamental infrastructure for the Openmatics platform. Fleet managers can now reduce fuel consumption and operating costs, and more efficiently manage vehicle usage, maintenance, and safety. The standards-based platform allows third-party suppliers to deploy their own vehicle telematics services as Openmatics apps and creates a de facto standard for the automotive industry, independent from a single manufacturer or service provider.” – Gero Strobel, Head of Development, Openmatics s.r.o. Challenges Create an industry standard for vehicle telematics by establishing a customizable platform that enables access to telematics information, such as current and past fuel consumption, through a web browser to better meet automotive market and customer needs Reduce fleet-management costs by eliminating the need to invest in isolated telematics hardware and software solutions per vehicle brand and vehicle component manufacturer Establish an open platform where third-party providers—such as original equipment manufacturers (OEM), insurers, fleet operators, and individual developers—can deploy their own vehicle telematics services Allow users to purchase targeted telematics services as single apps to reduce costs and ensure rapid growth of telematics services available on the platform Enable users to configure their telematics apps with ease to make sure the platform meets individual fleet management requirements, such as analyzing past and current fuel consumption of a truck fleet Solutions Deployed Oracle WebCenter Portal as a foundation for Openmatics, a standards-based automotive telematics platform that provides next-generation fleet management with unified digital communication from and to vehicles on the move Used Oracle Application Development Framework as the development framework for Oracle WebCenter Portal’s components and services, providing developers with ready-to-use software development kits with application programming interfaces, design templates, and visual tools that accelerated time to market Used Oracle Enterprise Pack for Eclipse to simplify telematics application development in Java Enabled fleet monitoring by recording vehicle data—such as fuel consumption information—through onboard units, delivering the information to Oracle Database, and making it accessible through a customizable app portfolio on any web browser Stored vehicle telematics data—sent as encrypted information—in Oracle Database, ensuring data integrity and immediate availability for the platform’s telematics applications Enabled a wide range of telematics services suppliers, from vehicle component manufacturers to fleet application developers, to offer vehicle telematics services on the Openmatics platform, ensuring platform independence from OEMs Provided Openmatics customers with the means to individually select the automotive telematics services that are relevant to their business requirements, eliminating the need to pay for superfluous information and reducing fleet management costs Oracle Products & Services Oracle Application Development Framework Oracle WebCenter Portal Oracle SOA Suite Oracle Enterprise Pack for Eclipse Oracle Database Oracle Consulting &amp;amp;amp;amp;amp;amp;amp;&amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;gt;amp;&amp;amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;amp;gt;lt;p&amp;amp;amp;amp;amp;amp;amp;amp;gt; &amp;amp;amp;amp;amp;amp;amp;amp;lt;/p&amp;amp;amp;amp;amp;amp;amp;amp;gt;
