  • Can T520+Bumblebee run an external monitor via DisplayPort?

    - by Fen
    Using 64-bit Ubuntu 11.10 and integrated (Intel) graphics, I can run the 1600x900 laptop display plus a 1600x1200 external monitor connected to the VGA adapter. But my external monitor is 1920x1200 so I have black stripes on each side. I believe the resolution is limited like this as the maximum resolution available from the Intel GPU is 2560x1600 = 4,096,000 pixels and I'm asking for a 3520x1200 = 4,224,000 display (with 1200x300 lost above the laptop screen). At 3200x1200 = 3,840,000 pixels, the Intel GPU seems happy. Under Windows, the same limit exists when using the VGA adapter, but if I turn Optimus on then I can connect the external monitor to the DisplayPort and get its full resolution and an extended desktop. I've seen that Bumblebee can run apps on the DisplayPort using the 'optirun' command. My question is: can Bumblebee run the DisplayPort in concert with the Intel card running the laptop screen creating a large virtual desktop (as on Windows)? If so, are there any pointers to how to do this? I tried once, failed, and dropped back to Integrated Graphics (and black stripes) as I could find no reports of this configuration working.

  • Graphical glitches on grub and ubuntu desktop

    - by Klyn
    I've decided to install ubuntu but neither ubuntu or any other linux distro won't even get to the desktop screen or work after getting there. On windows 8, everything is just fine. my new video card works perfectly and I have no problem with anything about it. then when I try to boot from ubuntu with wubi or with usb everything goes like this: 1) Grub screen...no problem at all, colors are just fine everything looks okay 2) and then linux boot screen...weird background color, over the backround there are vertical stripes of red-orange dots. but on the ubuntu logo and text, there are no dots at all! -I mean its shape is perfect- 3) desktop is about the start but * vertical stripes of red colored dots are all over the unity screen*. then when I click on ubuntu's menu, it usually switches to black screen saying something about "panic occured"...and then it restarts or it gives no respond at all. problems started after putting hd 6570 video card on my asus m5a78lm-lx video card which has amd phenom II X4 processor on it. I've searched to find something but there was no similar question that's why I'm almost sure it is kind of unique. again, I'm writing on Windows 8 right now and everything works and looks perfect. so far I've updated bios and anyone knows anything to solve this?

  • Stripe suppression algorithm needed

    - by maximus
    I have images with text. There are dark stripes in image that still exists in binary image too. That makes characters connected with that stripe - it can be vertical or horizontal (or at some angle) I need to remove them from image at first, and then to binarize. I've seen bandpass filter in ImageJ program that have some options like - suppress horizontal stripes, and it works good, but it also apply a bandpass filtering. So any idea please how to do it. I think it should be done in frequency domain.

  • Graphics artifacts/distortion with Win7 and nVidia

    - by Gepard
    Problem I encounter is rather hard to describe, so I provide a screenshot: http://dl.dropbox.com/u/1732760/video-distortion.png As you can see there are some horizontal stripes in random colors. These stripes appear sometimes in all windowed apps, games and on the desktop too. They tend to stay in place until I refresh window (or force it to to redraw by for example minimizing and maximizing again). They also tend to appear in the same place and shape multiple times, even if they disappear, it's very likely they will be again in the same place after a while. These artifacts do not blink or change if computer is idling. If I don't touch anything, do not use mouse, they will stay in place forever (unless some app redraws its window on its own). I first encountered this problem some weeks ago. Back then I thought it might be cooling problem, so I took out the graphics card, removed dust from the radiator and fan and put it into PC back. I also ran some stress test using Furmark (peak tempearature was ~65C) to see if the problem becomes more intense if the card gets hotter, but suprisingly no artifacts whatsoever appear during the stress test. Graphic card is Galaxy GeForce 7300 GT with DDR3 memory, was never overclocked. Drivers are the latest, from Nvidia site. OS is Windows 7 64-bit, updated. AMD64 3000+, 2GB RAM. I'm running a dual monitor setup with 2 19'' Samsung LCDs and problem is on both, so I assume it's not a monitor or cable issue.

  • how to reapply knockout binding

    - by MikeW
    Currently I have a knockout binding that stripes rows in a list which works fine ko.bindingHandlers.stripe = { update: function (element, valueAccessor, allBindingsAccessor) { var value = ko.utils.unwrapObservable(valueAccessor()); //creates the dependency var allBindings = allBindingsAccessor(); var even = allBindings.evenClass; var odd = allBindings.oddClass; //update odd rows $(element).children(":nth-child(odd)").addClass(odd).removeClass(even); //update even rows $(element).children(":nth-child(even)").addClass(even).removeClass(odd); ; } } Triggered from <button data-bind="click: addWidget" style="display:none">Add Item</button> The problem I have is when reloading data from the server , I call addWidget() manually in the view model the stripe binding handler is not applied - all rows appear as same color, if I click the html button then the binding happens and stripes appear var ViewModel = function() { self.addWidget(); }); Is it possible to reapply this custom binding manually in js? Thanks Edit: The stripe binding gets applied like so <div data-bind="foreach: widgets, stripe: widgets, evenClass: 'light', oddClass: 'dark'">

  • Electronic Door Lock Uses QR Codes As Keys

  • [Dear Recruiter] I'm an engineer trapped in a kittens body.

    - by refuctored
    Aditya -- I am very interested in pursuing the opportunity you've presented to me.  Let me assure you, there are very few individuals in Indianapolis with the skill set which I have so passionately trained to acquire.   Accompanying my skill set I do have a few quirks that you'll need to be okay with prior to placing me at a company. Bluntly, I feel like I'm a software engineer trapped in a cute little kitten's body.  I find that I am most comfortable going to work with a few stripes and whiskers painted on my face.  Coworkers will need to be okay with me grooming myself and making kitten noises whilst I do so.  I do occasionally let out a purr now and then, but not loud enough to disrupt anyone.  I always throw my arm-hair-balls in the appropriate trash receptacle. Will your company provide a scratching post or will I need to bring my own?  I can bring my own litter box. Meow-muh,George

  • How to shade a texture two different colors?

    - by Venesectrix
    To give an example of what I'm asking about, I'll use Saints Row 3 since I've been playing that lately. In that game you can customize your looks and your car's appearance a lot. Your coat can have a primary color and a trim color. Your car can have a primary color and a stripe color, etc. Is there just a single coat texture that is being shaded two different colors somehow or are they overlaying a transparent second texture for the trim/stripes that gets shaded differently? If it's just one texture I'd like to know how it's done. If it's two different textures it seems like it's a waste of space. The second texture would be the same size as the first one but mostly transparent if you just wanted to lay it on top of the first one. Or are they just carefully positioning a second, smaller texture so that it aligns properly with the first one?

  • We Heart Discussion Forums (and Know You Do Too)

    - by oracletechnet
    It's not generally known, but Oracle (via Oracle Technology Network) hosts one of the largest discussion forums instances (forums.oracle.com) on the planet (founded in 2001), containing nearly 10 million messages from 1 million registered users. That's a whole lot of conversations! And we really, really value those conversations - they span almost every conceivable technical subject across hundreds of products and technologies. More often not - and this is by design - those discussions are stewarded by community volunteers, many of whom are Oracle ACEs (who in fact earned their ACE stripes that way). And so, I am very happy to tell you that we have just initiated a project with our platform partner, Jive Software, to upgrade that platform to the most current, modern version available. The end result should be a vastly improved user experience for everyone involved, in all dimensions. There are many, many details to work on in coming weeks, but we'll keep you posted - and, when needed, come back to you for advice and suggestions. For now, we just wanted to share the good news!

  • What is the minimum of shader I need to use to run basic calculation on GPU?

    - by Jinxi
    I read, that the Hull Shader, Domain Shader, Geometry Shader and Pixel Shader can be used optional. So, is the Vertex Shader optional too? If no: What does a basic Vertex Shader look like? Just like a simple pass through? Is the Vertex Shader necessary to tell what kind of datastructure (Van Stripes or Meshes) are used? What can I do, with just the vertex shader? Are the fixed functions working without any help of programming a programmable stage?

  • Are there any new/updated Java web development frameworks to watch for?

    - by predhme
    I know recently Spring 3.0 was released which brought about a nice new set of features and ease of web development with their MVC package. However are there any new frameworks on the horizon and/or new versions of other frameworks that a web developer should have their eyes on? I heard about the Stripes framework, but it seems as though development has stopped. It also seems grails has a new release coming out as well which that looks like it is just an update to support the new features in the latest groovy release.

  • Getting jerky backgrounds on Win7 on iMac 27'' 2560x1440

    - by JohnIdol
    I installed Win7 on bootcamp on my new iMac 27'' (ATI videocard) and everything was good until recently I noticed that the default win7 background (then one on the background on login) looked jerky. When I say jerky I mean the kind of jerky you get if you can't display enough colours, and instead of nice fading shades you just get stripes and jerky patterns. I am on native resolution but even if I go down to 1920x1080 I get the same. This might have happened after a firmware update but as I don't use windows very often I am not too sure it's what caused it. Oh, and when I am playing games everything looks OK (as in not jerky!). Any help appreciated!

  • Is it possible to convert striped logical volume to linear logical volume?

    - by JooMing
    I've a logical volume that is striped across three physical volumes. I had to move this logical volume to another physical volume. This worked nicely with pvmove command. However, I discovered later that the logical volume is still striped and now all three stripes are on the same physical volume. Is there any way to convert striped logical volumes to linear logical volumes? I'm using LVM2 on linux. I figured that the obvious possibility is to rename the striped logical volume, create a new linear logical volume, and then copy data over, but that requires taking the filesystem system offline for some time. Unfortunately, I can't do that before the next week. Is there any better alternative?

    I'm editing my video in Windows Live Movie Maker from Live Essentials 2011. My source video is from camera and is .mp4 format with size of 1280 x 720. After editing in Movie Maker, I save the movie. And no matter what option I chose, I always end up with .wmv file, that is either 4:3 image with black stripes above and below the video, or 16:9 with black frame all around the image. What settings should I use, to be able to export or save the video in 1280 x 720 without any black border?

  • HTML CheckBox labels within a container are not displayed as expected

    - by Tiny
    The following HTML code attempts to display checkboxes inside a <div></div> container. <div style="overflow: auto; width: auto; display:block; max-height:130px; max-width:200px; background-color: #FFF; height: auto; border: 1px double #336699; padding-left: 2px;"> <label for="chk12" style='white-space: nowrap;'> <input type='checkbox' id="chk12" name='chk_colours' value="12" class='validate[required] text-input text'> <div style='background-color:#FF8C00; width: 180px;' title="darkorange">&nbsp;&nbsp;</div> </label> <label for="chk11" style='white-space: nowrap;'> <input type='checkbox' id="chk11" name='chk_colours' value="11" class='validate[required] text-input text'> <div style='background-color:#D9D919; width: 180px;' title="brightgold">&nbsp;&nbsp;</div> </label> <label for="chk10" style='white-space: nowrap;'> <input type='checkbox' id="chk10" name='chk_colours' value="10" class='validate[required] text-input text'> <div style='background-color:#76EE00; width: 180px;' title="chartreuse2">&nbsp;&nbsp;</div> </label> <label for="chk9" style='white-space: nowrap;'> <input type='checkbox' id="chk9" name='chk_colours' value="9" class='validate[required] text-input text'> <div style='background-color:#2E0854; width: 180px;' title="indigo">&nbsp;&nbsp;</div> </label> <label for="chk8" style='white-space: nowrap;'> <input type='checkbox' id="chk8" name='chk_colours' value="8" class='validate[required] text-input text'> <div style='background-color:#292929; width: 180px;' title="gray16">&nbsp;&nbsp;</div> </label> </div> What it displays can be visible in the following snap shot. It is seen that various colour stripes which are displayed using the following <div> tag <div style='background-color:#FF8C00; width: 180px;' title="darkorange">&nbsp;&nbsp</div> are displayed below their respective checkboxes which are expected to be displayed in a straight line even though I'm using the white-space: nowrap; style attribute. How to display each stripe along with its respective checkbox in a straight line? It was explained in one of my questions itself but in that question each checkbox had a text label in place of such colour stripes. Here it is. I tried to do as mentioned in the accepted answer of that question but to no avail in this case.

  • How can I find the right UV coordinates for interpolating a bezier curve?

    - by ssb
    I'll let this picture do the talking. I'm trying to create a mesh from a bezier curve and then add a texture to it. The problem here is that the interpolation points along the curve do not increase linearly, so points farther from the control point (near the endpoints) stretch and those in the bend contract, causing the texture to be uneven across the curve, which can be problematic when using a pattern like stripes on a road. How can I determine how far along the curve the vertices actually are so I can give a proper UV coordinate? EDIT: Allow me to clarify that I'm not talking about the trapezoidal distortion of the roads. That I know is normal and I'm not concerned about. I've updated the image to show more clearly where my concerns are. Interpolating over the curve I get 10 segments, but each of these 10 segments is not spaced at an equal point along the curve, so I have to account for this in assigning UV data to vertices or else the road texture will stretch/shrink depending on how far apart vertices are at that particular part of the curve.

  • Bizarre image loading problem from apache2

    - by NateDSaint
    Users have complained a few times about seeing a bizarre set of pink or green stripes on our webpage. At first I thought there were a rash of video card outages, but then someone sent me a screenshot from their browser (IE8). I later saw the same thing, but with slightly different colors on Chrome. Users have experienced this on their iPads and iPhones (iOS Safari). Because I've optimized the site to cache images, the bad image stays around until you clear your cache, so once you do, it resolves itself. My assumption is that the transmission of the image is being cut off mid-stream and then staying that way, but I can't for the life of me figure out why. Here's what I've checked: Header length is being sent, and transmission looks okay (wget sample below): wget http://www.superiorlivestock.com/templates/sla2/images/wallbg2.jpg --2012-04-05 08:46:00-- http://www.superiorlivestock.com/templates/sla2/images/wallbg2.jpg Resolving www.superiorlivestock.com (www.superiorlivestock.com)...

  • Cannot find GRUB - Ubuntu/Windows 8 dual-boot

    - by ubeatlenine
    Hello Ubuntu community, I find myself in an interesting situation. I have a Dell Inspiron 531 with Windows Vista. Recently my brother decided it would be a good idea to overwrite Vista with the Windows 8 consumer preview. Since we have had this PC for a very long time, we have long since lost the Vista CD, and according to the Windows 8 preview website you cannot recover your previous OS without it. I thought this would be a good opportunity to try out Ubuntu (since we obviously cannot keep the preview as an OS), but it appears that Ubuntu 11.10 Desktop is not compatible with Win8. Ubuntu doesn't run from the LiveUSB I made, instead it freezes on the loading screen and then disintegrates into black and white stripes. I blamed this failure on Ubuntu not being compatible with win8 yet and tried to install Ubuntu from the USB on a partition made from the remaining space on my hard drive - about 100GB. However the installer crashed while loading modules and told me I didn't have enough disk space. Since then, I have not been able to load either Ubuntu or Windows, BIOS is shifted over to the left of my screen, and I always get the same message: error: unknown filesystem grub rescue> typing "ls" at the prompt gives me the following: (hd0) (hd0,msdos7) (hd0,msdos6) (hd0,msdos5) (hd0,msdos2) (hd0,msdos1) does this mean I have multiple partitions running windows on my computer? Is it possible to recover Vista without the disk? Are all of my problems stemming from Ubuntu not being compatible with Win8 preview? (I realize the majority of my questions are about Windows, but seeing as the prompt I get is for grub I thought I would ask here first.) Any insight anyone has on this predicament would be greatly appreciated.

  • How to learn high-level Java web development concepts

    - by titaniumdecoy
    I have some experience writing web applications in Java for class projects. My first project used Servlets and my second, the Stripes framework. However, I feel that I am missing the greater picture of Java web development. I don't really understand the web.xml and context.xml files. I'm not sure what constitutes a Java EE application as opposed to a generic Java web application. I can't figure out how a bean is different from an ordinary Java class (POJO?) and how that differs from an Enterprise Java Bean (EJB). These are just the first few questions I could think of, but there are many more. What is a good way to learn how Java web applications function from the top down rather than simply how to develop an application with a specific framework? (Is there a book for this sort of thing?) Ultimately, I would like to understand Java web applications well enough to write my own framework.

  • hidden row causing issue with tablesorter zebra striping

    - by Harvengure
    Sorry if this has already been solved elsewhere but my searches have been able to turn up nothing and my attempts at solving the issue myself have made even less progress. :P Put quite simply I have a table that is using the jquery tablesorter and it's zebra widget. In this table there is a hidden column. I've so far been able to make it so that when a tr contains specific text (I was aiming for * but was seemingly unable to get \* to work for whatever reason...and I suspect my selector is perhaps not specific enough) the containing row is set not to display by ".hide()". The problem I am having though is when the row is hidden, tablesorter does exactly what it should do and stripes all the rows their specific colours based on their odd and even values. Of course .remove doesn't do the trick either as the table still sees some funny striping. Any thoughts on how to make it so that when a row is hidden, the striping compensates?

  • [Java] Form data transition into entity beans to persist them by the server side ORM

    - by cscsaba242
    Hello guys, Is there any good explanation or tutorial which describes the common way how can we create entity beans from the received data of the form ? The main reason of my question the treating the received ids (e.g id of country,city and so forth) which is the way from the id to entity ? Example: ................Client side form username:String countryid:Integer (could be a drop down) ................Server side entities public class UserBean { String username; CountryBean Country; } public class CountryBean { String cityname; Integer id; } ............................................ Maybe the question is dependent of the used technology, but I guess there is a very common way. I would like to comprehend the conventional approach of this problem. (For the sake of the completeness I would like to save the form data (received by Stripes) by JPA) Thanks advance. cscsaba242
