• installing 12.04 failing

  - by Steve

  I just downloaded 12.04 burned it to a cd, and booted to into it on my last built computer. It loads a purple screen, then goes to a dos looking screen with a blinking cursor then loads the ubuntu loader. The lights go from red to white and finally they all turn red. This is when the entire screen goes to noise and just hangs. Seems like a hardware issue but I can successfully boot into a non genuine windows7 that I'm looking to replace. I'm not sure what to try, so any help would be appreciated. Thanks.

• How to load kernel from live cd on UEFI install of Ubuntu 12.10?

  - by Geezanansa

  Running a GYGABYTE FM1 motherboard which is using a AMD 3870k APU with a new WS Caviar 1TB HDD. Following the advice in the Motherboard manual and https://help.ubuntu.com/community/UEFI have now got to grub screen for UEFI install. The dvd.iso being used is Ubuntu 12.10 desktop amd64. The hdd has had a gpt partition table made for, by using gparted when in a live desktop session(booted in bios mode)but decided to leave it unformatted with the intention of using installer to set up partitions. Booting live dvd gives grub list with the option to "install ubuntu" but get "can not read cd/0" and "the kernel must be loaded first" errors; when that option is selected. Any pointers on how to get installer going for UEFI install would be good. Thanks in advance.

• Nexus S 4g not detected by computer

  - by Newbie in over his head

  A little bit of a disclaimer, I have very little knowledge of the correct terminology for some of the things I'm going to ask about, and I apologize in advance I have a Nexus S 4g phone that is, at the moment of writing, connected to my 11.10 computer through its USB charger cable. In the past, connecting the phone like this has allowed me to transfer files between my computer and my phone; I'm able to get my music onto my phone, and my photos onto my computer, for example. For some reason, this has stopped working. My phone still charges its battery when connected to the computer, but neither the computer nor the phone recognized that they are connected. Is there something I can do to get the phone and the computer to detect each other? I don't know how to fix this, and it's more than a little frustrating. Any help would be greatly appreciated.

• How do I get HDMI out working on an Acer AC700 HDMI?

  - by Kyle

  I have installed Ubuntu on my Acer AC700 (Chromebook) using both the Cr-48 method and the script method both of which I think are the same. The only thing that does not work is HDMI out. I assume this is because it uses the Chrome OS kernel to boot so I have hoped that eventually it would update and work. I'm currently running 12.04 with Kernel 3.4.0 and still no luck. I've tried booting in recovery for Ubuntu and attempting to get Xorg to generate a new config but I don't know enough to do anything else and that didn't work. Am I the only one out there? Is there no one else who wants this to be possible Any help is greatly appreciated.

• .xprofile isn't enough

  - by BrianXP7

  I've been trying to find a solution on how to change the screen resolution on the login screen and other users. .xprofile will only affect my account. I've been searching for a few months but I got nothing. Please help. It would be easier if the "Default Resolution" was still there in the monitors settings. Plus, I'm afraid of editing the xorg.conf. Last time was ugly...

• Resolving equivalence relations

  - by Luca Cerone

  I am writing a function to label the connected component in an image (I know there are several libraries outside, I just wanted to play with the algorithm). To do this I label the connected regions with different labels and create an equivalence table that contain information on the labels belonging to the same connected component. As an example if my equivalence table (vector of vector) looks something like: 1: 1,3 2: 2,3 3: 1,2,3 4: 4 It means that in the image there are 2 different regions, one made of elements that are labelled 1,2,3 and an other made of elements labelled 4. What is an easy and efficient way to resolve the equivalences and end up with something that looks like: 1: 1,2,3 2: 4 that I can use to "merge" the different connected regions belonging to the same connected component? Thanks a lot for the help!

• Hosted News Carousel

  - by user19240

  I'm trying to add a news carousel on my OneHub site. I know there are quite a few plugins that I can use, but I'm looking for a ready-to-use hosted solution where people can log-on and manage the content, and I can simply include as an iFrame widget on our OneHub site. We would prefer to use Expression Engine, since we're using this on some of our other websites. It looks like Expression Engine + JQuery Cycle Rotator might be an option, not sure how easily I can get this onto OneHub though... WordPress has a carousel plugin as well that I'll explore. Anyhow, while I'm trying out these options, I figured I would put a question out there for any thoughts or advice, other solutions, etc. Any help would be greatly appreciated! Thanks, Alan

• My Computer in Ubuntu?

  - by Casey Hungler

  I was wondering if Ubuntu has an equivalent to the Windows feature "My Computer", which lists all available drives/storage devices. Typically, My Computer shows C:, which can be opened to view all of your directories and files. At this point, it is very similar to Ubuntu's Home Folder, but I am looking for something that allows me to view/select all available HDD's/Partitions. Here's my reason: I found a 6gb IDE HDD in my basement, and got an IDE cable for it. My desktop computer has a SATA drive in it, but has an IDE slot, so I wanted to plug it in and see what might be on it. The drive seems to be recognized in BIOS, but I can't find it in Ubuntu to view files, and Ubuntu is the only OS on that particular computer. If anyone has any ideas as to how to view the contents of that drive WITHOUT formatting it or tampering with the contents in any way, I would greatly appreciate your help. Thanks in advance!

• Compiling old versions of R (2.11 or older) on Ubuntu 13.10 (or newer)?

  - by user283293

  I am trying to compile an old version of R (2.11.1, specifically). "Why?", you might ask. Well, I have a program I am trying to run (that was not written by me, but I am hoping to use in my research) that was written in "old" R, and the program writer has specifically mentioned that R-2.11.1 or older must be used. I have run ./configure with no obvious errors (the entire output being far too long to post here, but I have been warned that I cannot make PDF, DVI, or HTML versions of the help pages, which I'm not too concerned about). Next, when I pass the make command, I am met with the following error (after a long stream of successful commands): Warning in solve.default(rgb): unable to load shared library '/home/sbowerma/Programs/R-2.11.1/modules//lapack.so': /home/sbowerma/Programs/R-2.11.1/lib/libRlapack.so: undefined symbol: _gfortran_compare_string Error in solve.default(rgb) : lapack routines cannot be loaded Error: unable to load R code in package 'grDevices' Execution halted However, I have confirmed that the library lapack.so is, in fact, in the exact position it is supposed to be.

• Flikering line on top of display

  - by jaskaran

  I just bought a new Dell Inspiron pre-installed with Ubuntu 11.10. All was fine until I updated the OS. Since then, I have this flickering line at the top of my screen and it won't go after rebooting or changing the screen resolution. It gets really annoying. I don't know which update did this. I tried reinstalling the image from Dell, and it worked fine until I applied the updates. I tried to take a screen shot but it does not show. The line seems to be outside the desktop area. Help please... Thanks!

• What to do if I hate C++ header files?

  - by BlaXpirit

  I was always confused about header files. They are so strange: you include .h file which doesn't include .cpp but .cpp are somehow compiled too. NOTE: I UNDERSTAND EVERYTHING ABOUT THE HEADERS, PLEASE DON'T TELL ME I'M STUPID OR SHOULD USE OTHER LANGUAGE Recently I joined a team project, and of course, both .h and .cpp are used. I understand that this is very important, but I can't live with copy-pasting every function declaration in each of multiple classes we have. How do I handle the 2-file convention efficiently? Are there any tools to help with that, or automatically change one file that looks like example below to .h and .cpp? (specifically for MS VC++ 2010) class A { ... Type f(Type a,Type b) { //implementation here, not in another file! } ... }; Type f(Type a) { //implementation here } ...

• Build automation: Is it usual to use QMake for non-Qt projects?

  - by Raphael

  So, I'm planning to write a C++ library and I want it to be cross-platform, and as this library won't deal with UI and I want it to have as little dependencies as possible, I won't be using Qt (actually Qt won't really help me to achieve what I want, all I plan on using is STL and Boost). Now when it comes to build a cross-platform project, I really like QMake as it's extremely easy to use and I have experience with it. I also heard good things about CMake, though I really doubt it's as easy to use as QMake. Anyway, here is my question: Should I stick with build automation tool that I know or is QMake just out of context for a non-Qt project? Should I take this as an opportunity to learn CMake? Or is there a better alternative to these two?

• How can I bind an interface to a class decided by an xml or database configuration at the launch of the application?

  - by ipohfly

  I'm re-working on the design of an existing application which is build using WebForms. Currently the plan is to work it into a MVP pattern application while using Ninject as the IoC container. The reason for Ninject to be there is that the boss had wanted a certain flexibility within the system so that we can build in different flavor of business logic in the model and let the programmer to choose which to use based on the client request, either via XML configuration or database setting. I know that Ninject have no need for XML configuration, however I'm confused on how it can help to dynamically inject the dependency into the system? Imagine I have a interface IMember and I need to bind this interface to the class decided by a xml or database configuration at the launch of the application, how can I achieve that?

• confusion understanding the fluid 2 column navigation layout

  - by Jason Madux

  I'm trying to understand the following cross-browser layout: http://matthewjamestaylor.com/blog/perfect-2-column-left-menu.htm but I'm having some confusion with some of its parts and there isn't enough information on the page or in the css comments to help me. What is the purpose of the .colleft div? Why can't the 2 columns be directly under the .colmask container? Why does the .colleft div have a right 75%? I don't understand its purpose/benefit. Why don't the widths of .col1 and .col2 add up to 100%? How was left:102% calculated for .col1 and left:6% for .col2? The comments for this are not very clear to me. How is it any different from not even specifiying a left/right css property?

• How to update a mesh position base on a pressed key?

  - by steven166

  I have a mesh loaded from a file, like a tiger mesh. At the first time it locates at A position, then if I press a left key, it will moves to B position but the problem is if I press a left key one more time, it will move from B position to C position. It means that the amount I want to move the mesh will base on the current position instead of the first time rendering position. I can do it if I have a array vertices then I just update the vertex buffer, but a mesh loaded from a file does not have an array vertices, so how to do it? Anybody help me, please?

• Kubuntu permanent install won't attach sound card

  - by rob

  I installed Kubuntu Live version and sound card visible in the volume/mixer panel. After installing the permanent version I have a dummy output where my sound card should be, therefore no sound. I re-installed the live version three times and then to permanent but the same problem each time. There is a very brief error on boot up to the permanent version that says: error. cannot attach card default. no such file or directory. I'm running Kubuntu 12.04 on a Mac G4 PPC with no other OS. I'm very new to Linux. I am able to follow instructions to help resolve this, but I'm not familiar with the OS.

• E-Mail Center: How to Debug Auto-Processing Issues

  - by LuciaC

  Do you use E-mail Center Auto-Processing functionality?  Auto-processing rules can be defined which will process an email and initiate actions such as sending an auto-reply, auto-acknowledgement or service request update or creation.  If you're using auto-processing in your environment, then you will have noticed that, when things go wrong, often the only indication that there is an issue is if the email goes to the Supervisor Queue for manual processing instead of being sent.  Oracle Development has developed a script to help you debug when an email is meant to be auto-processed but is failing. There are scripts for R12.0.6 through to R12.1.3. See Doc ID 1427925.1 for details of the script and how to use it.

• Unable to use separate X-Screen's GTX 550ti Ubuntu 12.10

  - by user12622

  I am currently trying to get from "Twin View" to using separate X screen's on Ubuntu 12.10, however I'm not having a great deal of luck. I am using an Nvidia GeForce GTX 550 Ti and am on driver version 304.51 Initially, when I turn on the separate X screens option, presents me on the 1 monitor with a box to accept the changes, however the 2nd screen goes black, and effectively, Ubuntu only seems to recognise the one screen. When I reboot, I boots back into Ubuntu with both screens working in Twinview. I'm not too sure where to start, but my xrandr can be found: Xrandr Any help is greatly appreciated, this is the last but one thing I need to make Ubuntu my only OS, so fingers crossed we can crack it :)
