  • Error after installing Ubuntu 12.04 using Wubi

    - by KJ50
    After using Windows Ubuntu Installer from within Windows, I am prompted to restart, so I follow the directions. When I try to start Ubuntu after restarting, the desktop background appears, but then a loading bar with this title appears. Verifying the installation configuration... While this is loading, an error window pops up that says No root file system is defined Please correct this from the partitioning menu There is only an 'Ok' button available to click, and if I click that the same error window appears. I do not know how to get to the "partitioning menu" from this state, so the only option I have is to shut down my computer. What can I do so that Ubuntu finds a "root file system"? Can I diagnose this problem via Windows? Does anyone have any insight? FYI - I am using a new ultrabook with 6GB RAM, Intel i7 3rd gen processor, and no CD/DVD drive.

  • Sprite rotation

    - by Kipras
    I'm using OpenGL and people suggest using glRotate for sprite rotation, but I find that strange. My problem with it is that it rotates the whole matrix, which sort of screws up all my collision detection and so on and so forth. Imagine I had a sprite at position (100, 100) and in position (100, 200) is an obstacle and the sprite's facing it. I rotate the sprite away from the obstacle and when move upwards my y axis, even though the projection shows like it's going away from the obstacle, the sprite will intersect it. So I don't see another way of a rotating a sprite and not screwing up all collision detection other than doing mathematical operations on the image itself. Am I right or am I missing something?

  • Apple Gets the Message About Centralized Notifications on Mobile

    - by ultan o'broin
    Yep, looks like iOS5 introduces a centralized messaging system: the Notification Center. Wonder where they got that idea from? Seriously, way to go though; this matches and probably betters what I really like about Android’s notifications system. I’ll have to check it out myself, though. Application UX's own research confirmed the centralized approach as something users wanted in research last year. This feature will really help the iOS in the enterprise user market too. Up to now, iOS is pretty dismal in the notifications space IMO.

  • USB internet not accessible

    - by Eric
    I'm brand new to ubuntu and linux. We access internet from a usb stick issued by a local telephone company. When I plug the stick into the computer, I see the device listed under internet connections as a mobile broadband device but it is grayed out and inaccessible. I tried to create a new mobile broadband connection but my country (Gabon) is not listed and we have no payment plans per se (we pay from a pre-paid card system).. Any clues as to how I can get the system to recognize the internet connection? Thanks for any help...

  • Programming Windows Identity Foundation - ISBN 978-0-7356-2718-5

    - by TATWORTH
    This book introduces a new technology that promises a considerable improvement on the ASP.NET membership system. If you ever had to write an extranet, system you should be aware of the problems in setting up membership for your site. The Windows Identity Foundation promises to be an excellent replacement. Therefore the book Programming Windows Identity Foundation - ISBN 978-0-7356-2718-5 at  http://oreilly.com/catalog/9780735627185, is breaking new ground. I recommend this book to all ASP.NET development teams. You should reckon on 3 to 5 man-days to study it and try out the sample programs and see if it can replace your bespoke solution. Rember this is version 1 of WIF and give yourself adequete time to read this book and familiarise yourself with the new software.

  • Dual-boot question involving separate HD and windows 8

    - by user286976
    I use an external HD with Ubuntu+GRUB on it. This allows me to effectively "hijack" most systems. Basically it's a permanent LiveUSB - my own system wherever I go. I use it for recovery mainly when Windows systems muck up, and for portability (as I can have my system on the go, without effecting the pc I'm borrowing, much like a LiveCD). I'm about to update to Windows 8 now [on a new, different computer]. Is there any special measure I should take to do this? I've seen a similar post here, but the OP had both harddrives plugged in simultaneously - that's not exactly my setup. Thank you :) EDIT: added for clarification that this is for a totally new computer.

  • Daemon for moving files between partitions?

    - by RATHI
    I have a system with Ubuntu installed in 20GB and windows in 100 GB, two partitions - each of 100GB using NTFS. While using DC++ (multiple downloading of big file) I used to get message that system is running out of memory. Is there any way to make a deamon which will be checking the Ubuntu partition so that if its used space goes up to a certain amount (let's say 18 GB) it will automatically start a moving file from this drive to another drive (let's assume it will pick the file from movie folder or largest media file from this drive to move)? Or it prompt to ask from user which file to move? Is there any program which can do this for me? If not, can you suggest something to read so that I could make it?

  • Mouse stopped responding after installing Ubuntu Server

    - by Danijar
    It was 2 operating systems on my machine, Windows 7 and Ubuntu Desktop 12.04, both 64bit version. All works well, firstly I installed Win, then the Desktop version of Ubuntu, lasts's GRUB rewrites windows's boot and of course added it as a variant to load. Yesterday I wish to play with Ubuntu Server 12.04, and install it as a third operating system. During the installation Server's GRUB seems to rewrite that which installed earlier (background color became black, was purple). Firstly, newly installed GRUB generates me overmuch load options for Ubuntu Desktop, by two for each kernel version (normal and recovery modes). OK, it's bearable, but most thing, that the mouse on this machine is totally stops responding, regardless which operating system I choose to load. Hope somebody help me. Thanks in advance!

  • Need to run `nvidia-xconfig` before booting

    - by RobinJ
    I formatted my whole hard drive, and installed Elementary OS (Ubuntu 10.10) on it in an attempt to get rid of all the problems. It failed. Every since I installed the nvidia-current drivers I first need to boot into recovery mode, and run sudo nvidia-xconfig before booting the system in the normal way. If I don't do this, it will just stop at a black screen after the boot screen, responding to nothing but CTRL+ALT+DELETE and the power button. When I boot the system after running the nvidia-xconfig command I can just start working as usual. Update I suspect it's got something to do with Plymouth. I shall have to try it again before I can confirm it, but removing the quiet and splash parameters from the kernel line in /boot/grub/grub.cfg seems to help. But still, I like my Plymouth screen. A black screen with text rolling over it (or without the text) doesn't attract me much.

  • Fast lookup for organization hierarchy

    - by Élodie Petit
    I need a way to implement a fast lookup algorithm / system to find users very quickly in a multi-level department and multi-level employee/manager relation organization structure. Departments can have any level of departments and users directly connected to departments. User are connected to departments and other users at the same time. What would be the best approach to implement such a system? There will be approximately 2000 users and 30 departments. Is there a good way to hold all of this information on memory?

  • Importing synaptics settings

    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?

  • Virtualbox, How do I change guest (precise) resolution to 16:9 (1920x1080) instead of default 4:3?

    - by CHolmstedt
    There are many questions about resolution issues on askubuntu but no question/solution seems to solve my issue. I've a 12.04/precise host system and installed Ubuntu 12.04/precise as guest system as well. After installation I had the option of selecting 1024x768 (4:3) and 800x600 (4:3) as resolution in display settings. After installing guest additions the options 1280x960 (4:3) and 1440x1050 (4:3) was added to the list. Now 4 in total all having the 4:3 ratio. I then activated full screen mode (host+f) and got the guest running in native 1920x1200 (16:10) for my screen. After deactivating full screen two more options had been added to the resolutions dropdown list, 1920x1200 (16:10) and 1600x1200 (4:3). I want to run the guest in 1920x1080 (16:9) so I can easily record screencasts in "full-hd". Last time I had this problem the solution was to run "VBoxManage controlvm nameofyourVM setvideomodehint width height colordepth" command from the host but now I want to know if there is any easier way to solve this?

  • How to build completely modular web applications

    - by Webnet
    In the coming months we're going to begin a project where we take a system we've built for a client (v1) and rebuild it from scratch. Our goal with v2 is to make it modular, so that this specific client will have their own set of modules they use, then another client may use a different set of modules altogether. The trick here is that Company A might have a series of checkout and user modules that change how that system works. Company B might stick with the standard checkout procedure but customize how products are browsed. What are some good approaches to application architecture when you're building an application from scratch that you want to have a Core that's shared among all clients while still maintaining the flexability for anything to be modified specifically for a client? I've seen CodeIgniter's hooks and don't think that's a good solution as we could end up with 250 hooks and it's still not flexible enough. What are some other solutions? Ideally we won't need to draw a line in the sand.

  • Ubuntu 11.04 seem's like a laggy OS

    - by user772401
    I'm new to Linux/Ubuntu in general. I just dual booted the Ubuntu 11.04 w/Windows 7 on my Lenovo laptop - Intel i7 Quad Core 2Ghz, 4Gb ram, etc. etc... and for some reason Ubuntu is very laggy and slow. When I'm switching between programs (Chromium, folders, software center, etc..) it doesn't run as smooth as windows 7 (I have no more than 3 programs/windows up at a time...). I don't think it's my system requirements bkz Linux OSs are known to use low system resources. Could be a bad install or do people find it slow and laggy in general or is it my PC mfg type?? I installed it using Wubi - should I do a reinstall? I've already done all the recommended updates..

  • Bitmap rotation jitter around pivot

    - by Manderin87
    I am working on a asteriods clone and I have the ship graphic loaded as a 96x96 bitmap. When the player rotates the ship I rotate the bitmap by degree (float). rotation function: if(m_Matrix == null) { m_Matrix = new Matrix(); } else { m_Matrix.reset(); } m_Matrix.setRotate(degree, m_BaseImage.getWidth() / 2, m_BaseImage.getHeight() / 2); m_RotatedImage = Bitmap.createBitmap(m_BaseImage, 0, 0, m_BaseImage.getWidth(), m_BaseImage.getHeight(), m_Matrix, true); draw function: m_Paint.setAntiAlias(true); m_Paint.setFilterBitmap(true); m_Paint.setDither(true); canvas.drawBitmap(m_RotatedImage, (int) posX - m_RotatedImage.getWidth() / 2, (int) posY - m_RotatedImage.getHeight() / 2, m_Paint); When the bitmap is drawn, the bitmap jitters slightly around the pivot. Can anyone fix or tell me why the bitmap is jittering around the pivot? It needs to be smooth.

  • How to make a minimal upgrade?

    - by wajed
    I use apt-get install --no-install-recommends ubuntu-desktop to install minimal desktop. I want to upgrade my system to the latest version (12.04) with it still being minimal. How do I do that? What I tried:- I tried Update Manager, and it gave me the Option to upgrade to 11.10 first, then to 12.04. What happened after I upgraded to 11.10 is that my desktop got bloated, and instead of the system using 500MB of RAM, now it uses about 1.5GB I can't even start apps anymore.

  • Microsoft Releasing Windows 8 in Late October

    The one thing Microsoft did not give was the exact date in October that this latest operating system would become available. But that may be difficult to predict. Brandon LeBlanc, Microsoft communications manager, stated only that Windows 8 is on track for a release to manufacturers (RTM) in August. The company, on average, produces a new version of Windows every three years; the last one to come out was Windows 7, back in October of 2009. The operating system will enjoy a widespread release, coming out in 109 languages across 231 markets throughout the world. It will be used not only in PCs...

  • USB keyboard does not load after 13.10 upgrade

    - by Paul
    Problem: Running kernel 3.11.0-12-generic after a Ubuntu upgrade from 13.04 to 13.10 my USB keyboard is not recognised, thus I am not able to unlock my encrypted disk. I suspect it might be related to a minimal/incorrect install of initrd. Question: How do I go about getting the newest kernel to recognise my generic USB keyboard, allowing me to unlock my encrypted disk? What I have tried: I have already re-installed the newest kernel: sudo apt-get install --reinstall linux-image-generic linux-image and I have also updated the initrd: update-initramfs -c -k 3.11.0-12-generic Back story: I just completed upgrading my Ubuntu system from 13.04 to 13.10. When I subsequently rebooted by system I was no longer able to enter my encryption password (passphrase) as the keyboard drivers did not load. Temporary workaround: Earlier in the boot process (before the keyboard stops working) I was able to enter GRUB menu were I choose to boot from an older kernel (3.8.0-31-generic) which did load the USB keyboard drivers. This is currently the kernel I am running. Thanks
