• Upgraded Ubuntu from 12.04 to 12.10 Ati radeon HD 3450 Catastrophe!

  - by minime

  When I had upgraded everything was ready on the screen om my computer and with my 12.04 ubuntu. When I restarted my system, the graphics card was not detected. I was forced to start the computer in low graphics mode, and eventually I had a pink deskop with only my maps, and no other programs at all. What do I do now? I need to recover the pictures on my system so that I can upload them online. I'd done a graphics card test on the terminal initially, and it showed that the card was compatible with unity 3D. I have an ATI radeon HD 3450 and I was running a 32 bit build of Ubuntu 12.04 initially Right now I have a broken install of Linux, with no working graphics card or desktop to start from, so I'm unsure of how to fix this.

• Monitor Settings

  - by user171625

  I'm having some viewing issues when I plug my projector in to view video. At first, the video didn't appear through the projector, only the computer screen. The projector just showed the desktop. I restarted and tried again, and it worked at first, but then the picture from the streaming video would freeze (the audio continued working) and I could do nothing. I had to manually shut down the computer. This happened a few more times before I gave up. Is there anything I can do about this?

• The entire User Interface freezes/becomes unresponsive for up to 20 seconds

  - by user2400801

  I am a rails developer, using Ubuntu 13.10 installed on a Asus S550C Ultrabook (was a windows 8 machine originally) Every day I work with Sublime Text 2, Google Chrome, and Terminal (about 6 tabs open) The problem: clicking on the menu bar (eg File - Save) while using Sublime Text 2 will occasionally (eg almost always) make the ENTIRE COMPUTER freeze for up to 20 seconds. This occasionally happens when I go to log out / lock my computer. Sometimes it doesn't freeze completely but rather is just very sluggish and then recovers. I don't know if this is a problem with Sublime Text 2, or the Ubuntu 13.10 operating system. (Thanks for reading) Best Regards

• Desktop in Kubuntu lacks bars and quite everything after trying to apply Plymouth fix for proprietary drivers

  - by Michcioperz

  I'm running Kubuntu 13.10, my computer's graphics card is Nvidia GT 520. I tried to fix that Plymouth's problem with proprietary graphics driver using an old script I found on the internet (it was coded for Natty, now that I think about it I shouldn't have done it). I ran that script and rebooted my computer. First incorrect behaviour I noticed was that Plymouth only displayed its text splash only on 1/4th of the screen, though when I pressed Esc key the logs were displaying correctly. Main problem appeared when I logged in. All my desktop's windows lack menu bar, can't be closed with Alt-F4, and they don't appear on the task bar. I tried fixing it by reinstalling GRUB a few times, purging /etc/grub.d and /boot/grub, but only the text splash issue was fixed. How can I fix that?

• laptop will not boot after attempting upgrade to 13.10

  - by naerwenya

  I wanted to update my OS to the new 14.04 LTS. I was running 12.04 LTS before and followed the advice that upgrades should be done in steps. I first upgraded to 12.10, which seemed to work fine, and later to 13.10. This was all done through the Software Manager. After the last upgrade, I am no longer able to boot up my computer. The GNU GRUB menu opens up, but after selecting Ubuntu, it just stalls with a blank purple screen. If I select one of the other kernels, it also stalls after "Loading initial ramdisk...". I can't get into the Recovery Menu, either. I'm still rather new to Linux and may have possibly made the situation worse. Unfortunately, nothing has worked yet. I tried reinstalling from a flash drive and on my first attempt, the wizard recognised a previous installation. Unfortunately, the wizard also didn't like how my partitions were set up (I didn't change anything) and gave an error before closing. Unfortunately, I didn't write the error down, but it was about the boot partition. On the next attempt and ever since, the installation wizard has stated that "This computer currently has no detected operating systems." This is strange, because I could see the disk and even access my files when booting up from the USB. At this point, I decided to back up my important files using dropbox. Before losing all my files, I wanted to try the Boot-Repair tool, which also produced no results, and the files are no longer visible when booting from USB. The link to the Boot-Repair log is at http://paste.ubuntu.com/7457249/. If I then proceed through to the "Something else" installation option, I can see that the partitions still exist. This is what they look like: /dev/sda free space (size indicated 1MB) /dev/sda1 efi (33MB of 98 MB used) /dev/sda2 efi (352634MB of 746330MB used) /dev/sda3 swap (3725MB, none used) free space (0MB) Is there any way I might be able to get my computer to work and preserve my files as well?

• Screen gets garbled on some web sites

  - by user10565

  I have a Gateway notebook with graphics card 01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series] with open source driver Linux version 2.6.32 -28 - generic. No other operating system on the computer. When I am using firefox to browse the web, everything normally works just fine except that when I attempt to access some particular web pages the screen completely messes up going mostly white with various streaks, etc., although I can access other pages of the same site without problems. When I run the cursor over the garbled screen, bits of the image recompose themselves, at least partially, and I can continue to open the applications window, or turn the computer off, or open the terminal, or take screen shots, etc., although all menus are unreadable. Also, when I zoom in on Google Earth the screen completely messes up. At all other times, there are no apparent problems. Any ideas?

• What is the "don't force full gpu scalling" configuration in the newest Nvida driver settings?

  - by wild_oscar

  I have a Zotac Ion board on a computer running Linux ad I had the driver version 295.xx. I was trying to run a 1080 video on XBMC and, because playback was a bit sluggish, part of my (unsuccessful) attempt at making it run smoothly was to upgrade the Nvidia driver. The problem is that the computer is connected by HDMI to a Pioneer A/V system - which in turn is connected to the TV (also through HDMI). When I created this set up I didn't get any image on my tv until I Unchecked "force full gpu scaling" in "Flat Panel Scaling". After upgrading the Nvidia driver I no longer have image. Upon investigating, I saw on the release changelog: Removed Flat Panel Scaling configurability in nvidia-settings. Any desired scaling can be configured through the new "ViewPortIn" and "ViewPortOut" MetaMode attributes. I know very little about this, however, so I'm lost. What would the correct configuration be with these new ViewPortIn/Out options to achieve the same result as "unchecking force full gpu scalling"?

• Wobbly windows not working in compiz for 12.04

  - by f22christian

  I'm very new at Ubuntu and am still trying to figure everything out. I recently downloaded Compiz settings manager and enabled wobbly windows. Nothing. So I uninstalled it and re-installed it and still, nothing. I've ran all the updates and updated the graphics drivers and I still have nothing. I have a Sony Vaio with a Intel® Core™2 CPU T5500 @ 1.66GHz × 2 . Its a 2009 computer, so I think it should be able to work just fine. Please help! I'm not a "computer wiz", so you'll need to put it in simpler terms for me. And yes, I am I do have Unity 3D. Thanks!

• How can I make my Java desktop application to run on different computers in a network locally and updating same mysql database?

  - by JaMpa

  I have developed Java desktop application for registration of students in the computer laboratories in our college, but what I need is to make this application whenever it runs on any computer (Windows XP machines) on the laboratory each and every data filled by the college students goes to the same MySql database (through WAMP server) running on the server machine (Win Server 2003). Also, I need this application to run during booting of windows computers in the laboratory for the purpose when any student tries to switch on any PC in the comp lab before interfacing the desktop icons should sign in through user name and password when he has already registered or signing up in order for getting the access.

• Ubuntu 12.10 hasa no wireless connectivity on Dell Inspiron 1520

  - by Jorge Tijerina

  I have just installed Ubuntu for the first time ever. I have just installed it in a Dell Inspiron 1520 that came pre installed with Windows Vista and i currently run both of the OS (I just choose when the computer starts up). The wifi definitely works on the computer since i used it to download Ubuntu in the first place when I was using Vista. The Network Manager says that I only have a 'Wired' Network and it doesn't have any other options to choose from. I connected the Laptop into a wired connection and downloaded the 'Wicd Network Manager' but it had no effect either. From there I continued to go into 'Software Sources' and installed the wireless drive but that had no effect either. So... What can I do?

• Font substitution

  - by sjdh

  What happens when you open a .docx document that is written in a font not available on your computer? How can you find the name of original font? I guess writer select automatically an other font. I tried to open a document written in Japanese. Writer shows the fond Droid Sans, and all the characters except number and Roman letters appear as squares. After changing to Droid Sans Japanese a few boxes are still left. I guess I have to install the original font on my computer, but I do not know the name of the font.

• Advice for last year college graduates

  - by Tomh

  Hey guys, I know there are many "advice" questions around this site. But I wanted to to narrow mine down to last year college students, in my case my last year as Master student in computer science. So far is a list of things I've done during my time in college (which I can recommend others to do aswell): Code a lot I've written several hobby projects, had part time jobs, entered the Imagine cup from Microsoft, took programming extensive courses and did freelance gigs. Read a lot I've bought most top books from the recommended book topics here, to be honest I have not read them all. learn different languages I've tried several languages including Haskell, Java, Python, Ruby, Lisp, Prolog, C#, PHP, JS, AS3 and possibly some more I forgot. Tried to start a blog Joel recommends to learn how to write, I tried starting a couple of blogs to improve upon this, I gave up on all instances after writing about three posts. It was just not my thing... Have a portfolio of launched projects/programs I'm busy with this, have a couple of finished, working projects I worked on to show to people. So this is my last year. Is there anything else you can recommend a last year college student to do before hitting the job market? Personally I'm tempted to spend my time on the following: Practice algorithm design Learn and memorize the usage of the low level API's of your favorite language Polish your portfolio Why? Because those first two will make sure you pass the majority of the interviews, here in Holland (I could be wrong). I rather not spend my time on those first two points, but I have to be realistic and thats just my experience on what kind of questions you'll get when you apply. The third point is my hope that I won't have to answer questions about the amount of standard types in c# for example if they can see I get projects done and launched. But I'm still graduating, so I don't know anything :), and many of you might be hiring grads on a recent base and could tell me and other interested people what you wish that the recent grads you interviewed would have done before they applied.

• Iterating throgh mvc model lists using javascript

  - by kapil

  I want to iterate through my model values. Following is what I did to achieve this. But the varible count never increments. How can I increment it to iterate throgh my model values? <script language="javascript" type="text/javascript"> function AddStudentName() { var StudentName = document.getElementById('txtStudentName').value; StudentName= StudentName.replace(/^\s+|\s+$/g, ''); if(StudentName!= null) { <%int count = 0; %> for(var counter = 0; parseInt(counter)< parseInt('<%=Model.StudentInfo.Count%>',10); counter++) { alert('<%=count%>'); if('<%=Model.StudentInfo[count].StudentName%>' == StudentName) { alert("A student with new student name already exists."); return false; } <%count = count +1;%> } } } </script> thanks, Kapil

• How do you marshall a parameterized type with JAX-WS / JAXB?

  - by LES2

  Consider the following classes (please assume public getter and setter methods for the private fields). // contains a bunch of properties public abstract class Person { private String name; } // adds some properties specific to teachers public class Teacher extends Person { private int salary; } // adds some properties specific to students public class Student extends Person { private String course; } // adds some properties that apply to an entire group of people public class Result<T extends Person> { private List<T> group; private String city; // ... } We might have the following web service implementation annotated as follows: @WebService public class PersonService { @WebMethod public Result<Teacher> getTeachers() { ... } @WebMethod public Result<Student> getStudents() { ... } } The problem is that JAXB appears to marshall the Result object as a Result<Person> instead of the concrete type. So the Result returned by getTeachers() is serialized as containing a List<Person> instead of List<Teacher>, and the same for getStudents(), mutatis mutandis. Is this the expected behavior? Do I need to use @XmlSeeAlso on Person? Thanks! LES

• Use Google Calendar UI but showing only filtered events

  - by Edwin

  I have just started using Google Calendar API (using Python client). I'm basically developing a web app for a school with Django. What I'd like to achieve is something like this: To make things simple for now, I have 1 Google account and all events will be created in the calendar under that account (this is the school calendar). The calendar will be made public. When a class is created by a teacher, the class schedule will be automatically added as an event in the Google Calendar. When a student logs in, he can see the school calendar, showing only schedules from the classes that he's registered in. I think I can filter the calendar feeds to show only class schedules that a student is registered in using Google Data API. The problem is, how can I display Google Calendar on my web app using Google Calendar UI to show only those filtered events? I can use Google Calendar UI with the provided embeddable HTML snippet, but I can't control/filter events with that (i.e. all events in the school calendar will be displayed). Or perhaps I'm missing something? I read the Data API guide and the Publishing tool doc but I can't seem to find this information. THanks in advance!

• Get data from database without refresh whole page

  - by stefanz

  Hello everybody. My project is about a school admin I have a page called : createClass.php, where user inserts grade, profile etc. When he press "submit" page called createdClass.php is loading. Inside this page I have all code which insert data into database and also an "if" structure which says : "Class already exists" if in database is another class with same specifications. Also in second page (createdClass.php) i have a small table which shows the place of each student. First time all cells are green (this means that place is free) and if i click one of them appear a popup window which let me to add info about student from that place. If a place is busy the cell will be red (take a look here : http://screencast.com/t/NzM2YzYxNjct). The big problem is that the cell will be red only after refresh the page (the place ask for data from database). If I press refresh appears "class already exists". To test the code i added in a comment all lines which verify and add respectively classroom . I think my problem can be solved with ajax. I'm waiting for an answer. Regards Stefan

• Can the Diamond Problem be really solved?

  - by Mecki

  A typical problem in OO programming is the diamond problem. I have parent class A with two sub-classes B and C. A has an abstract method, B and C implement it. Now I have a sub-class D, that inherits of B and C. The diamond problem is now, what implementation shall D use, the one of B or the one of C? People claim Java knows no diamond problem. I can only have multiple inheritance with interfaces and since they have no implementation, I have no diamond problem. Is this really true? I don't think so. See below: [removed vehicle example] Is a diamond problem always the cause of bad class design and something neither programmer nor compiler needs to solve, because it shouldn't exist in the first place? Update: Maybe my example was poorly chosen. See this image Of course you can make Person virtual in C++ and thus you will only have one instance of person in memory, but the real problem persists IMHO. How would you implement getDepartment() for GradTeachingFellow? Consider, he might be student in one department and teach in another one. So you can either return one department or the other one; there is no perfect solution to the problem and the fact that no implementation might be inherited (e.g. Student and Teacher could both be interfaces) doesn't seem to solve the problem to me.

• Using wildcards in prepared statement - MySQLi

  - by Michael Irwin

  Hi! I'm trying to run the following query, and I'm having trouble with the wildcard. function getStudents() { global $db; $users = array(); $query = $db->prepare("SELECT id, adminRights FROM users WHERE classes LIKE ? && adminRights='student'"); $query->bind_param('s', '%' . $this->className . '%'); $query->execute(); $query->bind_result($uid, $adminRights); while ($query->fetch()) { if (isset($adminRights[$this->className]) && $adminRights[$this->className] == 'student') $users[] = $uid; } $query->close(); return $users; } I'm getting an error that states: Cannot pass parameter 2 by reference. The reason I need to use the wildcard is because the column's data contains serialized arrays. I guess, if there's an easier way to handle this, what could I do? Thanks in advance!
