  • Sound coming out of headphone when running Ubuntu, but not window 7

    - by MrSimon
    I've downloaded Ubuntu yesterday, and I thought that everything went smoothly, until I found out a problem today. When I am running the Ubuntu OS on my laptop, the Samsung RC420, the speaker and the headphone works fine. However, when I am running the Window 7 OS, the speaker works fine, but my headphone will not emit any sound although the laptop has detected that 'a device has been plugged into the audio jack'. The same problem persist when I connect my X-minis as well. I tried updating my sound card drivers, check if they are hidden/disabled/disconnected and everything else. Nothing works :(

  • How do you dual boot Windows 7/8 seperatly with GRUB?

    - by Aaron
    I installed the beta version of Windows 8 and re-installed GRUB. When I boot my computer and select Windows 7, I get the new Windows 8 booting screen asking to boot between either Windows 7 or 8. If I choose Windows 7, my computer then restarts and I have to select Windows 7 again in order to boot into 7. But if I choose Windows 8 it boots right up. I understand I can choose which OS to boot by default, but I want my GRUB options to be the only way to choose between OS's. So my question is, how can I set this up so that when I click on Windows 7, I go there, and when I select Windows 8, I boot 8?

  • Google présente Chrome Web Store, son magasin d'applications a quelques similitudes avec celui d'App

    Google présente son Chrome Web Store, son magasin d'applications a quelques similitudes avec celui d'Apple La semaine dernière, Google a enchainé les annonces importantes lors de sa conférence de développement I/O. La firme semble mettre en place diverses nouveautés qui s'articulent autour de la sortie prochaine de son système d'exploitation Chrome OS. Vendredi a été présenté le Chrome Web Store, une boutique d'application qui commercialisera (ou offrira) des programmes pour les smartphones et terminaux mobiles utilisant Chrome ainsi que pour les ordinateurs équipés de Chrome OS (jeux, applications, plug-ins pour Chrome, etc.). A Mountain View, on semble donc vouloir fortement concurrence l'App Store. D'ailleurs, le...

  • removing ubuntu from a laptop (corrupted ubuntu)

    - by Ron
    I wanted to update my (very old) Ubuntu installation on my dual boot laptop. The other OS is win7. However, when I tried to boot into it I got: \ubuntu\winboot\wubildr.mbr cannot be loaded. Status 0xE0000000C. I assume the mbr is the master boot record for the Ubuntu installation. I looked at my C: drive and there's a WUBILDR and WUBILDR.MBR file there. Is it as simple as deleting them? ALSO, I just noticed there is no UBUNTU partition. If I delete these files and then get rid of the startup option for Ubuntu, is that all I have to do? (My goal is to have an up-to-date Ubuntu OS alongside Win 7).

  • Microsoft propose un kit gratuit d'initiation à Windows Phone 7 pour développer des applications et

    Microsoft propose un kit gratuit d'initiation à Windows Phone 7 Pour développer des applications et des jeux sur son nouvel OS mobile Microsoft a bien conscience que la bataille des OS pour smartphones se gagnera sur le front des applications. Et que derrière les applications, il y a les développeurs. Une réalité d'autant plus vraie pour Windows Phone 7 que la rétro-compatibilité avec Windows Mobile 6.x est rompue. Depuis avril, Microsoft avait sorti un kit de développement, baptisé Windows Phone Developer Tools. Aujourd'hui, c'est ce SDK et tout un ensemble d'outils complémentaires, de démos et de tutoriels

  • Microsoft réunit plus de 2500 développeurs autour de Windows 8 dans un coding marathon de 18h qui entre dans le record Guinness

    Microsoft réunit plus de 2500 développeurs autour de Windows 8 dans un coding marathon de 18h qui entre dans le record Guinness Windows 8 est la prochaine mise à jour majeure de l'OS de Microsoft. Entièrement repensé, il est en rupture totale avec les versions antérieures et permettra à Microsoft de faire son entrée sur le marché des tablettes. Il représente donc une nouvelle opportunité pour les développeurs qui seraient déjà assez enthousiastes face à l'OS.

  • How can I add missing Fn-key controls?

    - by Alex Ball
    I have a Toshiba NB200 netbook. The majority of the Fn-key controls come through fine and are recognized by my OS (I'm running Kubuntu 12.04/KDE 4.9) but according to the markings on my keyboard there are a few more that xev isn't detecting, i.e. Fn + F9 (touchpad toggle) Fn + 1 (increase screen resolution) Fn + 2 (decrease screen resolution) Fn + Space (zoom) Now, I don't particularly need those last three but I thought it would be quite useful to remap them to, say, Media Previous, Media Next, and Media Play, but I can't do that if the signals aren't getting through. Is there any way for me to persuade the OS to recognize these keystrokes? I've tried using acpi_listen to detect scancodes but it doesn't pick up any of function-related Fn-key strokes (like Audio Mute, which does work by the way).

  • Triple Boot Question

    - by Rick
    I have successfully set up a a win7,win8 and Ubuntu 12.10 system. Windows 8 and Ubuntu are located on the same SSD, while windows 7 is located on another SSD. All went great and I can continue playing around with all 3 OS's. My only annoyance is, while restarting, windows 7 boot loader runs first. If I select ubuntu in the win7 manager it then runs grub2 and asks me to select an os. I used easy bcd to add entries into win8's boot manager and was hoping to just use that one. I installed ubuntu's loader on to its own partition. Any suggestions to just use Win8 loader and still be able to choose between all 3?

  • What could be a reason for cross-platform server applications developer to make his app work in multiple processes?

    - by Kabumbus
    We consider a server app development - heavily loaded with messing with big data streams. An app will be running on one powerful server. A server app will be developed in form of crossplatform application - working on Windows, Mac OS X and Linux. So same code, many platforms for stand alone server architecture. We wonder what are the benefits of distributing applications not only over threads but over processes as well, for programmers and server end users? Some people said to me that even having 48 cores, 4 process threads would be shared via OS through all cores, is that true?

  • Windows 8/Surface Lunch Event Summary

    - by Tim Murphy
    Today was a big day for Microsoft with two separate launch event.  The first for Windows 8 and all of it’s hardware partners.  The second was specifically to introduce the Microsoft Windows 8 Surface tablet.  Below are some of the take-aways I got from the webcasts. Windows 8 Launch The three general area that Microsoft focused on were the release of the OS itself, the public unveiling of the Windows Store and the new devices available from its hardware partners. The release of the OS focused on the fact that it will be available at mid-night tonight for both new PCs and for upgrades.  I can’t say that this interested me that much since it was already known to most people.  I think what they did show well was how easy the OS really is to use. The Windows Store is also not a new feature to those of us who have been running the pre-release versions of Windows 8 or have owned Windows Phone 7 for the past 2 years.  What was interesting is that the Windows Store launches with more apps available than any other platforms store at their respective launch.  I think this says a lot about how Microsoft focuses on the ability of developers to create software and make it available.  The of course were sure to emphasize that the Windows Store has better monetary terms for developers than its competitors. The also showed off the fact that XBox Music streaming is available for to all Windows 8 user for free.  Couple this with the Bing suite of apps that give you news, weather, sports and finance right out of the box and I think most people will find the environment a joy to use. I think the hardware demo, while quick and furious, really show where Windows shine: CHOICE!  They made a statement that over 1000 devices have been certified for Windows 8.  They showed tablets, laptops, desktops, all-in-ones and convertibles.  Since these devices have industry standard connectors they give a much wider variety of accessories and devices that you can use with them. Steve Balmer then came on stage and tried to see how many times he could use the “magical”.  He focused on how the Windows 8 OS is designed to integrate with SkyDrive, Skype and Outlook.com.  He also enforced that they think Windows 8 is the best choice for the Enterprise when it comes to protecting data and integrating across devices including Windows Phone 8. With that we were left to wait for the second event of the day. Surface Launch The second event of the day started with kids with magnets.  Ok, they were adults, but who doesn’t like playing with magnets.  Steven Sinofsky detached and reattached the Surface keyboard repeatedly, clearly enjoying himself.  It turns out that there are 4 magnets in the cover, 2 for alignment and 2 as connectors. They then went to giving us the details on the display.  The 10.6” display is optically bonded to the case and is optimized to reduce glare.  I think this came through very well in the demonstrations. The properties of the case were also a great selling point.  The VaporMg allowed them to drop the device on stage, on purpose, and continue working.  Of course they had to bring out the skate boards made from Surface devices. “It just has to feel right” was the reason they gave for many of their design decisions from the weight and size of the device to the way the kickstand and camera work together.  While this gave you the feeling that the whole process was trial and error you could tell that a lot of science went into the specs.  This included making sure that the magnets were strong enough to hold the cover on and still have a 3 year old remove the cover without effort. I am glad that they also decided the a USB port would be part of the spec since it give so many options.  They made the point that this allows Surface to leverage over 420 million existing devices.  That works for me. The last feature that I really thought was important was the microSD port.  Begin stuck with the onboard memory has been an aggravation of mine with many of the devices in the market today. I think they did job of really getting the audience to understand why you want this platform and this particular device.  Using personal examples like creating a video of a birthday party and being in it or the fact that the device was being used to live blog the event and control the lights and presentation.  They showed very well that it was not only fun but very capable of getting real work done.  Handing out tablets to the crowd didn’t hurt either.  In the end I really wanted a Surface even though I really have no need for one on a daily basis.  Great job Microsoft! del.icio.us Tags: Windows 8,Win8,Windows 8 Luanch

  • Importing synaptics settings

    - by Marcus
    I've got a Samsung Series 5 Chromebook which I've installed Ubuntu on. In Chrome OS the clickpad is working great but in ubuntu it hasn't got the same settings so I'm having problems with selcting text. I managed to find the setting in Chrome OS, it's 120 about lines of settings looking like this: Device 'SynPS/2 Synaptics TouchPad': Device Enabled (131): 1 Coordinate Transformation Matrix (133): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 Device Accel Profile (265): -1 Device Accel Constant Deceleration (266): 1.000000 Device Accel Adaptive Deceleration (267): 1.000000 Device Accel Velocity Scaling (268): 10.000000 Device Node (250): "/dev/input/event6" Now I would like to import these settings to Ubuntu. Is that possible?

  • Le Mac App Store est ouvert depuis ce matin, mais il inquiète déjà certains développeurs

    Le Mac App Store est ouvert depuis ce matin, mais il inquiète déjà certains développeurs Mise à jour du 06.01.2011 par Katleen Comme nous vous l'avions annoncé il y a deux semaines, le Mac App Store est lancé ce jour. Un service de plus dans la panoplie d'Apple, qui ne cesse de s'étendre. Son objectif ? Offrir plus de visibilité à Mac OS X, l'OS de la firme. La boutique sera en effet disponible directement depuis celui-ci. Seulement, ce concept ne fait pas la joie de tout le monde : les développeurs commencent à grincer des dents. En effet, à cause de la prolifération des applications, qui sont de plus en plus nombreuses, un phénomène de concurrence s'est mis en place, e...

  • What Scripting Program would you choose to recover deleted and missing files?

    - by Steven Graf
    For a private project I'm looking for a command line tool to scan and recover files. I'm working on Gnome 3 (but I could also change my OS if it helps reaching my goal) and must be able to find and recover files on attached devices with formats such as NTFS, Fat32, MAC OS Extended and ext3. Is there a command line script to cover all of them or do I need to use different programs to reach my goal? can you recommend command line tools for these kind of tasks? is one of you willing and able to show me some examples and teach me further?

  • Network Computers Not Showing up

    - by Muhnamana
    Alright, 3 machines running, two using Ubuntu 11.10 and one on Mac OS X. On the two Ubuntu machines, both have samba installed and configured on the same workgroup, "HOME". On machine 1, I can see all networked machines. On machine 2, I can only see the Mac OS X machine. It doesn't show the other Ubuntu machine. What am I missing on machine 2 to see all networked computers? Any suggestions are welcome. I'm pretty much stumped.

  • Install/Downgrade kernel to v3.5.5 on Ubuntu 13.04

    - by Villi Magg
    I've been looking around the internet for a solution to downgrade the kernel from 3.8 to 3.5.5 since I've got the AMD/Ati Radeon Mobility HD 5600 graphic card on my machine. This video card in unfortunately not supported by the 3.8 kernel. And then when I've downgraded the kernel I need to install a version 12.* of the AMD Catalyst driver. There is too much in stake to wipe out the current installation of the OS and install an older OS. So I would like to avoid doing that to the ends of the world. Hope someone can help me with this one? Kind regards! Villi Magg.

  • Ubuntu version on external hardrive that shows up in GRUB?

    - by RPi Awesomeness
    I was wondering, is it possible to have Ubuntu installed on an external harddrive and still have it show up in GRUB? Of course, you wouldn't be able boot the other HDD OS unless it was connected, but would this work? I googled 'external HDD OS show in GRUB' and 'have external HDD show up in GRUB' but they didn't bring up anything. Does anyone have any resources to point me to? I can see this as being useful for testing out new releases or having multiple OSs installed without having to go through the BIOS boot choice. Thanks!

  • Why Android for new (micro) consoles?

    - by Klaim
    There are a lot of new (micro) consoles with Android inside coming soon or already there (OUYA for example). My question is: why use Android and not another OS as base for these consoles? I assume that there are pragmatic answers to this but I can't see any clear killer feature. For example, one can assume that any stable Linux distribution would work (like Valve seem to think). Android is primarily targetted at mobile platforms which mean it is built around the idea of being interrupted which goes against a lot of what console devs needs in new hardware - but is not killing Android as a platform for gamedev either as it's just a constraint. Why not another OS? What's the Android killer features that make micro-console builder using it instead of Linux or anything else?

  • Why was Tannenbaum wrong in the Tannenbaum-Torvalds debates?

    - by Robz
    I was recently assigned reading from the Tannenbaum-Torvalds debates in my OS class. In the debates, Tannenbaum makes some predictions: Microkernels are the future x86 will die out and RISC architectures will dominate the market (5 years from then) everyone will be running a free GNU OS I was a 1 year old when the debates happened, so I lack historical intuition. Why have these predictions not panned out? It seems to me, that from Tannenbaum's perspective, they're pretty reasonable predictions of the future. What happened so that they didn't come to pass?

  • Setting up lvm with HDD and SSD

    - by stonegrizzly
    My current hard drive is just about full and rather than just toss it and get a new one (since it works fine), I want to get a new drive and set them both up using lvm. While I'm at it, I also want to get an SSD to install the OS and applications on. This is my plan: Put / on the SSD (one partition) Put /tmp on a ram disk Put /var on a partition on my new drive Put /home on the rest of the new drive and my current drive using lvm. My goals are: Speed up boot time and application launch Minimize unnecessary writes to the SSD Never have to worry about which disk/partition to store my files on. I want the OS & lvm to take care of that Does this make sense? I'm fairly experienced with Ubuntu but I've never dealt with lvm before.

  • Getting Started Quickly

    - by Owen Allen
    If you're interested in using Ops Center, you'll want to get up and running as quickly and effectively as possible. One way to do this would be to work your way through the documentation library - use the Linux or Oracle Solaris install guides, then go through the Feature Guide and Admin Guide to start using the software. They're thorough, but they're a lot of reading. But if you're looking to install a simple deployment quickly, and you don't want to do all of the configuration work right off the bat, you can use the Quick Start Guide. It's a streamlined procedure that runs you through installing a single Enterprise Controller and co-located Proxy Controller, and then shows you how to discover assets quickly. Once you've discovered these assets, it describes how to use the analytics feature to view their performance, and use monitoring to keep track of their statuses and health. You'll have to do some additional configuration to use features like OS provisioning, OS updates, and virtualization, but the Quick Start guide gives you an overview of how to install and start using features quickly.

  • Core i7 with 4GB - go 64 bit or stay 32bit..?

    - by tommed
    I have a Core i7 laptop with 4gb ram. In windows, the disadvantage of using the 32bit OS would be that a single app could not use more than 2gb of ram (+ the 2gb shared kernel-space memory) except when setting a boot switch which reduces the amount of shared kernel memory, then it's 3GB max per app. What disadvantages/limitations would I have in Ubuntu for sticking to the 32bit OS? (If any?) - As I only have 4GB of ram, I can't see why I need to use the 64bit version?
