  • Ubuntu 12.10 AMD/Intel Hybrid Graphics not working

    - by Marian Lux
    On Ubuntu 12.04 my Sony Vaio VPCSE with Intel® HD Graphics 3000 and AMD Radeon™ HD 6630M worked fine with the Catalyst Control Center version 12.6. Also the switching between integrated and discrete graphic card was working. In both cases, I followed this tutorial. But it is not working on Ubuntu 12.10. I tested the tutorial with the Catalyst Control Center from the Ubuntu Software Center, the version 12.8 and version 12.9. Always the same problem: After installation process I am able to boot in the login-screen. But after entering the password for my username, only the background-image appears. Unity seems not to be starting. I am only able to reach the context-menu by right clicking the mouse button. I also tried his fix, but is also does not work for me. Any ideas what to do to fix this problem?

I don't have to press any key or use mouse, it logs in automatically. But Its not working when keyboard is not connected. OS boots and stops on login screen. I can't connect keyboard in final kiosk hardware installation.

  • Customizing UPK outputs (Part 2 - Player)

    - by [email protected]
    There are a few things that can be done to give the Player output a personalized look to match your corporate branding. In my previous post, I talked about changing the logo. In addition to the logo, you can change the graphic in the heading, button colors, border colors and many other items. Prior to making any customizations, I strongly recommend making a copy of the existing Player style. This will give you a backup in case things go wrong. I'd also recommend that you create your own brand. This way, when you install the newest updates from us, your brand will remain intact. Creating your own brand is pretty easy. Make sure you have modify permissions on the publishing styles directory, if you are using a multi-user installation. Under the Publishing/Styles folder, create a new folder with your company name. Copy all the publishing styles from the UPK folder to your newly created folder. Now, when you go through the Publishing wizard, you will have two categories to choose from: the UPK category or your custom category. Now, for updating the Player output. First, the graphic that appears on the right hand side of the Player. If you're using a multi-user installation, check out the player style from your custom brand. Open the player style. Open the img folder. The file named "banner_image.png" represents the graphic that appears on the right hand side of the player. It is currently sized at 425 x 54. Try to keep your graphic about the same size. Rename your graphic file to be "banner_image.png", and drag it into the img folder. Save the package. Check in the package if you are in a multi-user installation. You've just updated the banner heading! Next, let's work on updating some of the other colors in the player. All the customizable areas are located in the skin.css file which is in the root of the Player style. Many of our customers update the colors to match their own theme. You don't have to be a programmer to make these changes, honest. :) To change the colors in the player: Make a copy of the original skin.css file. (This is to make sure you have a working version to revert to, in case something goes wrong.) Open the skin.css file from the Player package. You can edit it using Notepad. Make the desired changes. Save the file. Save the package. Publish to view your new changes. When you open the skin.css, you will see groupings like this: .headerDivbar { height: 21px; background-color: #CDE2FD; } Change the value of the background-color to the color of your choice. Note that you cannot use "red" as a color, but rather you should enter the hexadecimal color code. If you don't know the color code, search the web for "hexadecimal colors" and you'll find many sites to provide the information. Here are a few of the variables that you can update. Heading: .headerDivbar -this changes the color of the banner that appears under the graphic Button colors: .navCellOn - changes the color of the mode buttons when your mouse is hovering on them. .navCellOff - changes the color of the mode buttons when the mouse is not over them Lines: .thorizontal - this is the color of the horizontal lines surrounding the outline .tvertical - this is the color of the vertical lines on the left and right margin in the outline. .tsep - this is the color of the line that separates the outline from the content area Search frame: .tocSearchColor - this is the color of the search area .tocFrameText - this is the background color of the TOC tree. Hint: If you want to try out the changes prior to updating the style, you can update the skin.css in some content you've already published for the player (it's located in the css folder of the player package). This way, you can immediately see the changes without going through publishing. Once you're happy with the changes, update the skin.css in player style. Want to customize more? Refer to the "Customizing the Player" section of the Content Development manual for more details on all the options in the skin.css that can be changed, and pictures of what each variable controls. I'd love to see how you've customized the player for your corporate needs. Also, if there are other areas of the player you'd like to modify but have not been able to, let us know. Feel free to share your thoughts in the comments. --Maria Cozzolino, Manager of Requirements & UI Design for UPK

  • Using Jquery.Form Plugin + MultiFile to automatically upload a single file

    - by Alan Neal
    I wanted to find a way to upload a single file*, in the background, have it start automatically after file selection, and not require a flash uploader, so I am trying to use two great mechanisms (jQuery.Form and JQuery MultiFile) together. I haven't succeeded, but I'm pretty sure it's because I'm missing something fundamental. Just using MultiFile, I define the form as follows... <form id="photoForm" action="image.php" method="post" enctype="multipart/form-data"> The file input button is defined as... <input id="photoButton" "name="sourceFile" class="photoButton max-1 accept-jpg" type="file"> And the Javascript is... $('#photoButton').MultiFile({ afterFileSelect: function(){ document.getElementById("photoForm").submit(); } }); This works perfectly. As soon as the user selects a single file, MultiFile submits the form to the server. If instead of using MultiFile, as shown above, let's say I include a Submit button along with the JQuery Form plugin defined as follows... var options = { success: respondToUpload }; $('#photoForm').ajaxForm(options); ... this also works perfectly. When the Submit button is clicked, the form is uploaded in the background. What I don't know how to do is get these two to work together. If I use Javascript to submit the form (as shown in the MultiFile example above), the form is submitted but the JQuery.Form function is not called, so the form does not get submitted in the background. I thought that maybe I needed to change the form registration as follows... $('#photoForm').submit(function() { $('#photoForm').ajaxForm(options); }); ...but that didn't solve the problem. The same is true when I tried .ajaxSubmit instead of .ajaxForm. What am I missing? BTW: I know it might sound strange to use MultiFile for single-file uploads, but the idea is that the number of files will be dynamic based on the user's account. So, I'm starting with one but the number changes depending on conditions.

  • How can I get six Xbox controllers to provide input to an HTML5 game?

    - by Daniel X Moore
    I'm creating a six player HTML 5 game designed to be played locally (Red Ice). I've previous set up handling 7 Wiimotes using something along the lines of Joy2Key to map each input for each player to a separate keyboard key, but Wiimotes are pretty hard on the hands for these types of games and not very ergonomic so I thought I'd try and get Xbox controller support. I don't believe that any simple key mapping solution will work due to the nature of the directional stick. My inclination is that this will require a browser plugin and if so I'd prefer to write the plugin for Google Chrome. How do I create a Chrome browser plugin to handle multiple Xbox controllers or is there some other way? Please do not answer this question saying it can't be done, because it absolutely can. EDIT: I don't believe any keymapping/mouse simulating solution will work unless it can reliably distinguish six axis of inputs, one per player.

  • More Than Headsets: 5 Things You Can Do With Bluetooth

    - by Chris Hoffman
    Your laptop, smartphone, and tablet probably all have integrated Bluetooth support. Bluetooth is a standard that allows devices to communicate wirelessly. Most people are familiar with Bluetooth headsets, but there are more things you can do with Bluetooth. To make two Bluetooth devices work together, you’ll have to “pair” them. For example, you can pair a Bluetooth mouse with your laptop, pair a Bluetooth headset with your phone, or pair your smartphone with your laptop.

  • Unable to wake display with remote

    - by Eugene
    I'm running an HTPC (xbmc) without a keyboard/mouse attached, running oneiric. After some indeterminate amount of time, sometime between 1 and 12 hours, the display goes to sleep. The computer itself is not sleeping, I can still SSH to it from another computer. The remote will not wake the display. The IR receiver is working, as irw will show me the remote key presses. The only way to get my display back is to restart the display manager, lightdm in this case. Does anybody know a way to keep the display from going to sleep? I don't really need any power management at all considering that it connects to my TV and when I want my display to go to sleep, I turn off my TV.

  • 2D basic map system

    - by Cyril
    i'm currently coding a 2D game in Java, and I would like to have some clues on how-to build this system : the screen is moving on a grander map, for instance, the screen represent 800*600 units on a 100K*100K map. When you command your unit to go to another position, the screen move on this map AND when you move your mouse on a side or another of the screen, you move the screen on the map. Not sure that i'm clear, but we can retrieve this system in most RTS games (warcraft/starcraft for example). I'm currently using Slick 2D. Any idea ? Thanks.

  • Creating a column of RadioButtons in Adobe Flex

    - by adnan
    I am having an un-predictable behavior of creating radio buttons in advancedDataGrid column using itemRenderer. Similar kind of problem has been reported at http://stackoverflow.com/questions/112036/creating-a-column-of-radiobuttons-in-adobe-flex. I tried to use the same procedure i.e. bind every radio button selectedValue and value attributes with the property specified in the property of the associated bean but still facing the problem. The button change values! The selected button becomes deselected, and unselected ones become selected. Here is the code of my advancedDataGrid: <mx:AdvancedDataGrid id="adDataGrid_rptdata" width="100%" height="100%" dragEnabled="false" sortableColumns="false" treeColumn="{action}" liveScrolling="false" displayItemsExpanded="true" > <mx:dataProvider> <mx:HierarchicalData source="{this.competenceCollection}" childrenField="competenceCriteria"/> </mx:dataProvider> <mx:columns> <mx:AdvancedDataGridColumn headerText="" id="action" dataField="criteriaName" /> <mx:AdvancedDataGridColumn headerText="Periode 1" dataField="" width="200"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center" width="100%" verticalAlign="middle"> <mx:RadioButton name="period1" value="{data}" selected="{data.period1}" group="{data.radioBtnGrpArray[0]}" visible="{data.showRadioButton}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> <mx:AdvancedDataGridColumn headerText="Periode 2" dataField="" width="200"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center" width="100%" verticalAlign="middle"> <mx:RadioButton name="period2" value="{data}" selected="{data.period2}" group="{data.radioBtnGrpArray[1]}" visible="{data.showRadioButton}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> <mx:AdvancedDataGridColumn headerText="Periode 3" dataField="" width="200"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center" width="100%" verticalAlign="middle"> <mx:RadioButton name="period3" value="{data}" selected="{data.period3}" group="{data.radioBtnGrpArray[2]}" visible="{data.showRadioButton}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> </mx:columns> </mx:AdvancedDataGrid> Any work around is highly appreciated in this regard!

  • OpenGL programming vs Blender Software, which is better for custom video creation?

    - by iammilind
    I am learning OpenGL API bit by bit and also develop my own C++ framework library for effectively using them. Recently came across Blender software which is used for graphics creation and is in turn written in OpenGL itself. For my part time hobby of graphics learning, I want to just create small-small movie or video segments; e.g. related to construction engineering, epic stories and so on. There may be very minimal to nil mouse-keyboard interaction for those videos, unlike video games which are highly interactive. I was wondering if learning OpenGL from scratch is worth for it or should I invest my time in learning Blender software? There are quite a few good movie examples are created using Blender and are shown in its website. Other such opensource cross platform alternatives are also welcome, which can serve my aforementioned purpose.

  • Dell Inspiron touchpad not working

    - by Bobby
    I own a Dell Inspiron on which I installed 12.04 on. Everything was working great up until a couple of weeks ago when the Touchpad stopped working. It doesn't show up in mouse/touchpad settings either. I was wondering if anyone has had the same problem with 12.04 and was able to fix it. I am a noob when it comes to computer code and stuff like that, so please try to keep the answer noob proof. Also, does anyone know if the guys behind Ubuntu will have an update to fix this problem?

  • Can't get my head arround background workers in c#

    - by Connel
    I have wrote an application that syncs two folders together. The problem with the program is that it stops responding whilst copying files. A quick search of stack-overflow told me I need to use something called a background worker. I have read a few pages on the net about this but find it really hard to understand as I'm pretty new to programming. Below is the code for my application - how can I simply put all of the File.Copy(....) commands into their own background worker (if that's even how it works)? Below is the code for the button click event that runs the sub procedure and the sub procedure I wish to use a background worker on all the File.Copy lines. Button event: protected virtual void OnBtnSyncClicked (object sender, System.EventArgs e) { //sets running boolean to true booRunning=true; //sets progress bar to 0 prgProgressBar.Fraction = 0; //resets values used by progressbar dblCurrentStatus = 0; dblFolderSize = 0; //tests if user has entered the same folder for both target and destination if (fchDestination.CurrentFolder == fchTarget.CurrentFolder) { //creates message box MessageDialog msdSame = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "You cannot sync two folders that are the same"); //sets message box title msdSame.Title="Error"; //sets respone type ResponseType response = (ResponseType) msdSame.Run(); //if user clicks on close button or closes window then close message box if (response == ResponseType.Close || response == ResponseType.DeleteEvent) { msdSame.Destroy(); } return; } //tests if user has entered a target folder that is an extension of the destination folder // or if user has entered a desatination folder that is an extension of the target folder if (fchTarget.CurrentFolder.StartsWith(fchDestination.CurrentFolder) || fchDestination.CurrentFolder.StartsWith(fchTarget.CurrentFolder)) { //creates message box MessageDialog msdContains = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "You cannot sync a folder with one of its parent folders"); //sets message box title msdContains.Title="Error"; //sets respone type and runs message box ResponseType response = (ResponseType) msdContains.Run(); //if user clicks on close button or closes window then close message box if (response == ResponseType.Close || response == ResponseType.DeleteEvent) { msdContains.Destroy(); } return; } //gets folder size of target folder FileSizeOfTarget(fchTarget.CurrentFolder); //gets folder size of destination folder FileSizeOfDestination(fchDestination.CurrentFolder); //runs SyncTarget procedure SyncTarget(fchTarget.CurrentFolder);

  • Is it possible to get the old workspaceswitcher back in the top-panel?

    - by Arne
    I just updated my Ubuntu from 10.04 to 12.04 yesterday and so far I'm very satisfied with it. There is only one thing which is still missing to get back just the same comfort as I had with the previous version. I work on 4 workspaces and would like to have the ability to switch from one to another by just one click. With Gnome there was the possibility to add the workspace switcher to the top-panel next to the system tray and I could easily click on just the workspace I wanted to switch to. Of course there I could switch by using the keyboard shortcuts, but I would like to use the mouse in addition. I don't like using the switcher on the left side because it's much slower. Is it possible to get the old workplace switcher back in the panel at the top?

  • console windows not close after stopping program

    - by robUK
    Hello, Visual Studio 2005 C++ Windows XP Pro I have a sample application that I am testing, that links with boost libraries. However, the program runs ok. However, when I try and stop the program by clicking the 'Stop Debugging' button. The program ends, but the console window remains open. So I have many of them, as during my testing I am starting and stopping the application. Even when I try and close it by clicking the close button it has no affect. And it doesn't seem to appear under task manager when the program ends. The only way I can close them if I reboot windows. I am thinking it might be a thread that has not closed, and maybe that is keeping the console windows open. Many thanks for any advice,

  • Removing active class and adding it to a sibling

    - by Kyle
    Currently, I have a jQuery Cycle plugin that allows the image to scroll. With it's callback I am calling this function function onAfterVideoScroll() { $('.myRemote.active').removeClass("active").next().addClass("active"); } This SHOULD be removing the current class from another set of links, and adding the class to the it's next sibling. This is to keep whichever image is showing it's button predecessor will be active so the user can tell which button is currently showing on the slideshow. If this makes sense, please let me know why it will remove the active class but it never gives the sibling the active class. Thanks!

    I am having trouble with Ubuntu 12.10. Everything is working fine, although there is a slight problem. It seems to lag every once in a while, as in I will move the mouse, then about two seconds later the cursor will actually move on the screen. Is there any way to fix this? This is my first day using Ubuntu and I put it on a computer I built myself. I don't have much experience so a detailed answer would be very much appreciated.

  • Ios Parse Login

    - by user3806600
    I am programming an IOS app that will use parse to login a user. Using storyboard I have the login button connected to another view controller with the push segue. Whether the username and password are correct the button selection always goes to the new view controller. I might be doing this all wrong. Any help is appreciated. Here is my code: - (IBAction)signIn:(id)sender { [PFUser logInWithUsernameInBackground:self.emailField.text password:self.passwordField.text block:^(PFUser *user, NSError *error) { if (!error) { [self performSegueWithIdentifier:@"signIn" sender:nil]; } else { // The login failed. Check error to see why. } }]; }

  • Augmenting your Social Efforts via Data as a Service (DaaS)

    - by Mike Stiles
    The following is the 3rd in a series of posts on the value of leveraging social data across your enterprise by Oracle VP Product Development Don Springer and Oracle Cloud Data and Insight Service Sr. Director Product Management Niraj Deo. In this post, we will discuss the approach and value of integrating additional “public” data via a cloud-based Data-as-as-Service platform (or DaaS) to augment your Socially Enabled Big Data Analytics and CX Management. Let’s assume you have a functional Social-CRM platform in place. You are now successfully and continuously listening and learning from your customers and key constituents in Social Media, you are identifying relevant posts and following up with direct engagement where warranted (both 1:1, 1:community, 1:all), and you are starting to integrate signals for communication into your appropriate Customer Experience (CX) Management systems as well as insights for analysis in your business intelligence application. What is the next step? Augmenting Social Data with other Public Data for More Advanced Analytics When we say advanced analytics, we are talking about understanding causality and correlation from a wide variety, volume and velocity of data to Key Performance Indicators (KPI) to achieve and optimize business value. And in some cases, to predict future performance to make appropriate course corrections and change the outcome to your advantage while you can. The data to acquire, process and analyze this is very nuanced: It can vary across structured, semi-structured, and unstructured data It can span across content, profile, and communities of profiles data It is increasingly public, curated and user generated The key is not just getting the data, but making it value-added data and using it to help discover the insights to connect to and improve your KPIs. As we spend time working with our larger customers on advanced analytics, we have seen a need arise for more business applications to have the ability to ingest and use “quality” curated, social, transactional reference data and corresponding insights. The challenge for the enterprise has been getting this data inline into an easily accessible system and providing the contextual integration of the underlying data enriched with insights to be exported into the enterprise’s business applications. The following diagram shows the requirements for this next generation data and insights service or (DaaS): Some quick points on these requirements: Public Data, which in this context is about Common Business Entities, such as - Customers, Suppliers, Partners, Competitors (all are organizations) Contacts, Consumers, Employees (all are people) Products, Brands This data can be broadly categorized incrementally as - Base Utility data (address, industry classification) Public Master Reference data (trade style, hierarchy) Social/Web data (News, Feeds, Graph) Transactional Data generated by enterprise process, workflows etc. This Data has traits of high-volume, variety, velocity etc., and the technology needed to efficiently integrate this data for your needs includes - Change management of Public Reference Data across all categories Applied Big Data to extract statics as well as real-time insights Knowledge Diagnostics and Data Mining As you consider how to deploy this solution, many of our customers will be using an online “cloud” service that provides quality data and insights uniformly to all their necessary applications. In addition, they are requesting a service that is: Agile and Easy to Use: Applications integrated with the service can obtain data on-demand, quickly and simply Cost-effective: Pre-integrated into applications so customers don’t have to Has High Data Quality: Single point access to reference data for data quality and linkages to transactional, curated and social data Supports Data Governance: Becomes more manageable and cost-effective since control of data privacy and compliance can be enforced in a centralized place Data-as-a-Service (DaaS) Just as the cloud has transformed and now offers a better path for how an enterprise manages its IT from their infrastructure, platform, and software (IaaS, PaaS, and SaaS), the next step is data (DaaS). Over the last 3 years, we have seen the market begin to offer a cloud-based data service and gain initial traction. On one side of the DaaS continuum, we see an “appliance” type of service that provides a single, reliable source of accurate business data plus social information about accounts, leads, contacts, etc. On the other side of the continuum we see more of an online market “exchange” approach where ISVs and Data Publishers can publish and sell premium datasets within the exchange, with the exchange providing a rich set of web interfaces to improve the ease of data integration. Why the difference? It depends on the provider’s philosophy on how fast the rate of commoditization of certain data types will occur. How do you decide the best approach? Our perspective, as shown in the diagram below, is that the enterprise should develop an elastic schema to support multi-domain applicability. This allows the enterprise to take the most flexible approach to harness the speed and breadth of public data to achieve value. The key tenet of the proposed approach is that an enterprise carefully federates common utility, master reference data end points, mobility considerations and content processing, so that they are pervasively available. One way you may already be familiar with this approach is in how you do Address Verification treatments for accounts, contacts etc. If you design and revise this service in such a way that it is also easily available to social analytic needs, you could extend this to launch geo-location based social use cases (marketing, sales etc.). Our fundamental belief is that value-added data achieved through enrichment with specialized algorithms, as well as applying business “know-how” to weight-factor KPIs based on innovative combinations across an ever-increasing variety, volume and velocity of data, will be where real value is achieved. Essentially, Data-as-a-Service becomes a single entry point for the ever-increasing richness and volume of public data, with enrichment and combined capabilities to extract and integrate the right data from the right sources with the right factoring at the right time for faster decision-making and action within your core business applications. As more data becomes available (and in many cases commoditized), this value-added data processing approach will provide you with ongoing competitive advantage. Let’s look at a quick example of creating a master reference relationship that could be used as an input for a variety of your already existing business applications. In phase 1, a simple master relationship is achieved between a company (e.g. General Motors) and a variety of car brands’ social insights. The reference data allows for easy sort, export and integration into a set of CRM use cases for analytics, sales and marketing CRM. In phase 2, as you create more data relationships (e.g. competitors, contacts, other brands) to have broader and deeper references (social profiles, social meta-data) for more use cases across CRM, HCM, SRM, etc. This is just the tip of the iceberg, as the amount of master reference relationships is constrained only by your imagination and the availability of quality curated data you have to work with. DaaS is just now emerging onto the marketplace as the next step in cloud transformation. For some of you, this may be the first you have heard about it. Let us know if you have questions, or perspectives. In the meantime, we will continue to share insights as we can.Photo: Erik Araujo, stock.xchng

  • UIViewControllers - TabBarApplication - iPhone SDK

    - by Kevin
    Hello everyone, I am very new to the iPhone SDK. I need to know if in a tab bar application I need to make UIViewController classes. For example, when I make a new tab bar application there is a default FirstViewController class (.h, .m) already there. Now if I have code on the second tab, would I need to create a SecondViewController class? If not, how would I make a button on the 2nd tab, and make that button do something. I'm not really sure how to do it, because the FirstViewController works with the buttons and code, but if I make a SecondViewController, and I link everything my app crashes. If anyone could help it would be greatly appreciated. Kevin
