  • Correcting color-shifted mirrored i915 driver in 12.04?

    - by Will Martin
    I was called in to fix a friend's malfunctioning HP Pavilion. She's not sure exactly which model, but the sticker on the bottom says "G60". The problem was a failed upgrade to 12.04. I was able to mostly repair it with sudo apt-get -f install, which ran setup and configuration for several hundred packages. The biggest problem at the moment is Xorg. The login screen (lightdm) loads normally but at a reduced resolution (1024x768 instead of 1366x768). But once you log in, it looks like this: Observe that the colors of the dock on the left and the bar at the top are normal. But the background is filled with bizarro color-skewed ghost images of the desktop. In all cases, the actual contents of any programs you run is a totally illegible mess, except that the bar at the top of any program windows looks and acts normally. And the ghost images are interactive! For example, if you click the icon in the top right corner to get the "shut down" menu, the same menu will appear in the ghost images below. Starting a terminal will start a terminal window in both the real desktop and the ghost images, and moving it around updates both the real and ghost desktops. I suspect Xorg is using some kind of wrong driver and/or parameter for the graphics hardware. Here is the graphics-relevant portion of the lspci -v output: 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 09) Subsystem: Hewlett-Packard Company Device 360b Flags: bus master, fast devsel, latency 0 Capabilities: [e0] Vendor Specific Information: Len=0a <?> Kernel driver in use: agpgart-intel 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 360b Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at d0000000 (64-bit, non-prefetchable) [size=4M] Memory at c0000000 (64-bit, prefetchable) [size=256M] I/O ports at 5110 [size=8] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 3 Kernel driver in use: i915 Kernel modules: i915 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) Subsystem: Hewlett-Packard Company Device 360b Flags: bus master, fast devsel, latency 0 Memory at d2500000 (64-bit, non-prefetchable) [size=1M] Capabilities: [d0] Power Management version 3 I'm not sure what to check next. I would ordinarily check xorg.conf to see what it says, but that apparently doesn't exist any more, and my googling has not yielded any useful techniques for getting Xorg to tell me what settings it decided to use. The weird part is that it works fine on the login screen. It's only when you actually log in as a user that the display gets screwed up. Suggestions?

  • Changing save directory

    - by Nathan
    Disregard my previous pre-edit post. Rethought what I needed to do. This is what I'm currently doing: https://developer.mozilla.org/en/XPCOM_Interface_Reference/nsIScriptableIO downloadFile: function(httpLoc) { try { //new obj_URI object var obj_URI = Cc["@mozilla.org/network/io-service;1"].getService(Ci.nsIIOService). newURI(httpLoc, null, null); //new file object //set file with path obj_TargetFile.initWithPath("C:\\javascript\\cache\\test.pdf"); //if file doesn't exist, create if(!obj_TargetFile.exists()) { obj_TargetFile.create(0x00,0644); } //new persitence object var obj_Persist = Cc["@mozilla.org/embedding/browser/nsWebBrowserPersist;1"]. createInstance(Ci.nsIWebBrowserPersist); // with persist flags if desired const nsIWBP = Ci.nsIWebBrowserPersist; const flags = nsIWBP.PERSIST_FLAGS_REPLACE_EXISTING_FILES; obj_Persist.persistFlags = flags | nsIWBP.PERSIST_FLAGS_FROM_CACHE; //save file to target obj_Persist.saveURI(obj_URI,null,null,null,null,obj_TargetFile); return true; } catch (e) { alert(e); } },//end downloadFile As you can see the directory is hardcoded in there, I want to save the pdf file open in the active tab to a relative temporary directory, or anywhere that's out of the way enough that the user won't stumble along and delete it. I'm going to try that using File I/O, I was under the impression that what I was looking for was in scriptable file I/O and thus disabled.

  • Subscribing to MSMQ over the internet

    - by Nathan Palmer
    I haven't been able to find a clear answer to this problem. Is there a good way to subscribe to a MSMQ through the internet? Ideally I need security both in authentication and encryption for this connection. But I would like the subscriber to act just like any other client that would be subscribed on the local network. I believe I have a couple of options here Expose the MSMQ ports publicly Put the MSMQ behind some type of WCF service (not sure if that works for a subscriber) What other options do I have? We're sitting in a .NET environment and the main problem domain that is trying to be solved is to change the remote connections from a pulling system to an event based system to reduce the load on the main server.

  • GLSL Shader Effects: How to do motion blur, etc?

    - by DevilWithin
    I am not sure how right it is to ask this question, but still here it goes. I have a full 2D environment, with sprites going around as landscape, characters, etc And to make it more state-of-art looking, i want to implement a motion blur effect, similar to modern FPS's (i.e. crysis) blur when moving fast the camera. In a sidescroller, the desired effect is having this slight blur appearing to give the idea of fast movement, when the camera is moving. If anyone could give me some tips on doing this, im assuming in a pixel shader, i'd be grate. Also, if anyone has other good tips on cool pixel shader effects for 2D games it would be awesome, like some stylizing post fx, such as previous Prince of Persia illustrative style. Thanks

  • Width of li with two floats different in IE, correct in FF

    - by Nathan Loding
    I've worked out most of the kinks with my "lava-lamp" effect that I'm trying to create. Basically I want two curly braces (both are images) to wrap a list-item, then follow over to the next list-item. I always build in FF, then make exceptions for IE. I can't figure out what exception I need to make! I'm using an absolutely positioned li that contains two div's. The first div is floated left, the second is floated right. The width of the li is set to the width of the li it supposed to be wrapping. Thus creating the effect of the braces on the left and right sides of the text. It works beautifully in Firefox, but IE has two issues: The bottoms of the images are cut off. Sometimes they reappear when the animation ends, sometimes they don't. I assume this has to do with height, but no matter what I set the height to, it fails! The width is completely wrong. Here's a live example of it: http://jsbin.com/odome/2 The left position in IE is always 5-7px more than in FF, but that's a small difference. I'm more concerned with the width and the bottoms of the images being trimmed. Thanks, as always, for the help!

  • Create Personalized Controls For Java ME

    - by Nathan Campos
    I'm starting to develop a eBook reader for mobile using Java ME, but for the control were the book will be shown I need a personalized control. For this I need to first know how to do one, to workaround with my needs. Then I need to know how can I do a personalized control as we do with Visual Basic. PS: I want to do a personalized TextBox, that in some parts can be in bold, italic, sublined, that supports topics(as the Edit, the MS-DOS Text Editor) and many other things that make a eBook better viewed than a simple plain text

  • Why aren't min-width and max-width working as I expect?

    - by Nathan Long
    I'm trying to adjust a CSS page layout using min-width and max-width. To simplify the problem, I made this test page. I'm trying it out in the latest versions of Firefox and Chrome with the same results. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Testing min-width and max-width</title> <style type="text/css"> div{float: left; max-width: 400px; min-width: 200px;} div.a{background: orange;} div.b{background: gray;} </style> </head> <body> <div class="a"> (Giant block of filler text here) </div> <div class="b"> (Giant block of filler text here) </div> </body> </html> Here's what I expect to happen: With the browser maximized, the divs sit side by side, each 400px wide: their maximum width Shrink the browser window, and they both shrink to 200px: their minimum width Further shrinking the browser has no effect on them Here's what actually happens, starting at step 2: Shrink the browser window, and as soon as they can't sit side-by-side at their max width, the second div drops below the first Further shrinking the browser makes them get narrower and narrower, as small as I can make the window So here's are my questions: What does max-width mean if the element will sooner hop down in the layout than go lower than its maximum width? What does min-width mean if the element will happily get narrower than that if the browser window keeps shrinking? Is there any way to achieve what I want: have these elements sit side-by-side, happily shrinking until they reach 200px each, and only then adjust the layout so that the second one drops down? And of course... What am I doing wrong?

  • Cast errors with IXmlSerializable

    - by Nathan
    I am trying to use the IXmlSerializable interface to deserialize an Object (I am using it because I need specific control over what gets deserialized and what does not. See my previous question for more information). However, I'm stumped as to the error message I get. Below is the error message I get (I have changed some names for clarity): An unhandled exception of type 'System.InvalidCastException' occurred in App.exe Additional information: Unable to cast object of type 'System.Xml.XmlNode[]' to type 'MyObject'. MyObject has all the correct methods defined for the interface, and regardless of what I put in the method body for ReadXml() I still get this error. It doesn't matter if it has my implementation code or if it's just blank. I did some googling and found an error that looks similar to this involving polymorphic objects that implement IXmlSerializable. However, my class does not inherit from any others (besides Object). I suspected this may be an issue because I never reference XmlNode any other time in my code. Microsoft describes a solution to the polymorphism error: https://connect.microsoft.com/VisualStudio/feedback/details/422577/incorrect-deserialization-of-polymorphic-type-that-implements-ixmlserializable?wa=wsignin1.0#details The code the error occurs at is as follows. The object to be read back in is an ArrayList of "MyObjects" IO::FileStream ^fs = gcnew IO::FileStream(filename, IO::FileMode::Open); array<System::Type^>^ extraTypes = gcnew array<System::Type^>(1); extraTypes[0] = MyObject::typeid; XmlSerializer ^xmlser = gcnew XmlSerializer(ArrayList::typeid, extraTypes); System::Object ^obj; obj = xmlser->Deserialize(fs); fs->Close(); ArrayList ^al = safe_cast<ArrayList^>(obj); MyObject ^objs; for each(objs in al) //Error occurs here { //do some processing } Thanks for reading and for any help.

  • Creating a form dynamically

    - by Nathan
    Hi, I use a search button that creates a form dynamically at the server side and returns it with Jquery syntax. After I fill-up the form and click on submit button, there is another .submit() Jquery function that suppose to be called to validate input before data is sent to the server. But, for some reason, this function is never called, and the data is request is sent. In more details: This is the form that the serach button creates dynamically at the server side and "prints" to html page with Jquery: <form action=... name="stockbuyform" class="stockbuyform" method="post"> <input type=text value="Insert purchasing amount"> <input type="submit" value="Click to purchase"> </form> And here is the .submit() function : $(".stockbuyform").submit(function() { alert("Need to validate purchasing details"); } But whaen I click on purchase button, the .submit() function is never called. Does it mean that I can't use another Jquery call with the answer I got in the first call?

  • Can PHP dissect its own syntax?

    - by Nathan Long
    Can PHP dissect its own syntax? For example, I'd like to write a function that takes in an input like $object->attribute and says to itself: OK, he's giving me $foo->bar, which means he must think that $foo is an object that has a property called bar. Before I try accessing bar and potentially get a 'Trying to get property of non-object' error, let me check whether $foo is even an object. The end goal is to echo a value if it is set, and fail silently if not. I want to avoid repetition like this: <input value="<? if(is_object($foo) && is_set($foo->bar)){ echo $foo->bar; }?> "/> ...and to avoid writing a function that does the above, but has to have the object and attribute passed in separately, like this: <input value="<? echoAttribute($foo,'bar') ?>" /> ...but to instead write something which: preserves the object-attribute syntax is flexible: can also handle array keys or regular variables Like this: <input value="<? echoIfSet($foo->bar); ?> /> <input value="<? echoIfSet($baz['buzz']); ?> /> <input value="<? echoIfSet($moo); ?> /> But this all depends on PHP being able to tell me "what kind of thing am I asking for when I say $object->attribute or $array[$key]", so that my function can handle each according to its own type. Is this possible?

  • Version control: delete branches after merging?

    - by Nathan Long
    When you branch some code, finish working with the branch, and merge it back to the trunk, what do you do with the branch? Delete it from the repository? Keep it for reference? It seems like you would keep it for reference, but I imagine the /branches directory could get pretty cluttered. (If this isn't something people generally agree on, please comment and I'll make it a community wiki.)

  • Best solution for managing navigation (and marking currently active item) in CakePHP

    - by Nathan
    So I have been looking around for a couple hours for a solid solution to handling site navigation in CakePHP. Over the course of a dozen projects, I have rigged together something that works for each one, but what I'm looking for is ideally a CakePHP plugin that handles the following: Navigation Model Component for handing off to the view Element View Helper for displaying the navigation (with control over sublevels displayed and automatically determining the "active" item based on URL and/or controller/model/slug Admin pages for managing a tree of navigation Any suggestions for an all-in-one solution or even the individual components would be very appreciated! Or even suggestions on how you have handled it in the past

    Hello I am a beginning android developer using windows and the eclipse IDE to develop java android applications.I have published one game but there is a free version of the game and a paid version. The google market insists that the different versions must have different package names. So far i have been refactoring the package with 2 different names and changing the R resource file import each time i build the different versions. The code is 99% the same for both versions.Is there a better way?

  • jQuery Validate - can I re-validate a group of fields after changing one?

    - by Nathan Long
    I'm using jQuery Validate and would like to re-validate a group of fields whenever one of them is changed (or possibly, whenever one of them validates successfully). My attempts so far just create infinite loops. Is this possible, or does the plugin design preclude it? (Specifically, I've got a method that requires at least X of group Y to be filled out, and as soon as that's true, I'd like all those fields to re-validate. Currently I'm clearing out their error messages with my own code, but that's a hack - it also hides unrelated validation problems until the form is re-submitted.)

  • How can I package sqlite with my Perl for Windows application?

    - by Paul Nathan
    I need to set up sqllite for Perl on a Windows box. However - Perl is probably being run over the network from a central server, and I do not know what modules will be available on initial running of my script. I can guarantee Perl 5.8+ (activestate) or Perl 5.10+ (strawberry). Therefore, I need to package sqlite & the associated Perl module(s) in the project directory itself. Having Goggled around, I don't see any immediate zipfile to do this.

  • How can you get a list or traversable tree of bookmarks from within a Firefox Extension?

    - by Nathan
    I am working on a simple Firefox Extension, and I need a list of the user's bookmarks. I have found the nsINavBookmarksService class which appears to be the recommended way of manipulating bookmarks since Firefox 3.0. Strangely I don't see a method that I could use to get a list of all the bookmarks in a folder. I need some way of creating a flat list of all the Bookmark URIs, but without any methods that return information about more than one bookmark I don't see a way to do it.
