  • BlockingQueue decorator that logs removed objects

    - by scompt.com
    I have a BlockingQueue that's being used in a producer-consumer situation. I would like to decorate this queue so that every object that's taken from it is logged. I know what the straightforward implementation would look like: simply implement BlockingQueue and accept a BlockingQueue in the constructor to which all of the methods would delegate. Is there another way that I'm missing? A library perhaps? Something with a callback interface?

  • How do I re-install Unity after uninstalling gnome-shell?

    - by Florian
    I am using Ubuntu 14.04. I have big issues with the Unity desktop. I installed then uninstalled gnome-shell (using "apt-get autoremove --purge gnome-shell"). Since then, my desktop has no background and no icons. Plus, and this is the bothering part, unity is very unstable. On startup, there is a huge use of memory, much more than before. Sometimes, I also cannot minimize a window without having the desktop freezing and having to kill the process in question with tty1. I have tried to use : apt-get autoremove --purge ubuntu-desktop apt-get install ubuntu-desktop But it does not change a thing. I tried to update my video drivers but it is still the same. How can I reinstall the unity desktop thoroughly (obviously, something in its install is broken) ? If it is not possible, is it safe that I create a new partition on my disk where I will put my files and reinstall Ubuntu on the old partition (I do have a USB install of Ubuntu 14.04 but not enough space to save my files on it) ?

  • How to enable Unity 3D support in 12.04 using open-source drivers for RadeonHD cards?

    - by martin
    As the title says I can't enable the Unity 3D support when I'm using open-source drivers (xorg-edgers). I have an xfx Radeon HD 6950 by the way. If I install the proprietary 12.3 drivers from AMD it works, but I get poorer 2D performance than the open-source drivers and also I get some freezes and lock ups at random. So because of this I'm trying the open-source drivers and so far no issues at all, except this one. Running this command $ /usr/lib/nux/unity_support_test -p shows this: OpenGL vendor string: VMware, Inc. OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x300) OpenGL version string: 2.1 Mesa 8.0.2 Not software rendered: no Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no And this command $ lspci -nn | grep VGA shows: 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI Cayman PRO [Radeon HD 6950] [1002:6719] So, is this normal? Do I need to go back to proprietary drivers to enable Unity 3D? If anyone can give me help, I'll much appreciate it.

  • How to get Unity working on dual gpu laptop?

    - by Mourgos
    I recently bought a new laptop (Asus X53S series) that has two GPUs, an NVidia GeForce GT 540M and an integrated Intel GPU (I believe it's called Intel HD graphics 3000). I installed the recommended restricted NVidia drivers after a clean Ubuntu 11.10 install. In the 'additional drivers' program I get the message: "This driver is enabled and in use", although when I try to open the NVidia X Server Settings it says "You do not appear to be using the NVIDIA X driver." which seems to be the case since Ubuntu only starts using Unity 2D. I've had the same issue in 11.04 and I was forced to use the nouveau driver just to get unity working, but since I get quite a few crashes with it I really want to get the propriety driver working this time around. Since I've never had this issue with older laptops, I can only assume it is caused due to the dual gpu configuration. How do I get Ubuntu to use the propriety drivers, or is there any workaround to get the integrated Intel GPU to be ignored by Ubuntu? Alternatively, has anyone got Unity working with a similar setup?

  • How to squeeze the maximum performance out of Unity and GNOME 3?

    I see that I do not get good performance with the new Unity desktop, but I should say that Unity has improved a lot since the last edition Ubuntu 11.10.

  • How to pass an interface to Java from Unity code?

    - by nickbadal
    First, let me say that this is my first experience with Unity, so the answer may be right under my nose. I've also posted this question on Unity's answers site, but plugin questions don't seem to be as frequently answered there. I'm trying to create a plugin that allows me to access an SDK from my game. I can call SDK methods just fine using AndroidJavaObject and I can pass data to them with no issue. But there are some SDK methods that require an interface to be passed. For example, my Java function: public void attemptLogin(String username, String password, LoginListener listener); Where listener; is a callback interface. I would normally run this code from Java as such: attemptLogin("username", "password", new LoginListener() { @Override public void onSuccess() { //Yay! do some stuff in the game } @Override public void onFailure(int error) { //Uh oh, find out what happened based on error } }); Is there a way to pass a C# interface through JNI/Unity to my attemptLogin function? Or is there a way to create a mimic-ing interface in C# that I can call from inside the Java code (and pass in any kind of parameter)? Thanks in advance! :)

  • Ubuntu Screenshot Window Class

    - by Weylin Schreck
    I would like to know the class for the "thing" that pops up when you take a screen shot using the default screen capture utility in Ubuntu 12.04. When I do a full screen capture it lags a lot because of particular animation I use to open things like drop down menus. Therefore I’d like to disable that only. If someone could provide me with the window "class=" or however I would disable the animation there it would be greatly appreciated.

  • Cisco Unity Connection 7 and Exchange 2010 Unified Messaging

    - by Jason N. Gaylord
    We are looking to get our Cisco Unity Connection 7 to store messages using Exchange Server 2010 Unified Messaging. Is anyone aware of any whitepaper/document/tutorial or other that they'd recommend we look into? We can't seem to find much. From what I here from our Cisco partner is that the connection works, but will be better in the next release. Thanks in advance.

  • Cannot get webapps to work after upgrade from 12.04 to 12.10

    - by kashan
    I just upgraded to Ubuntu 12.10 from 12.04. But I cannot use WebApps. In fact there is no sign of them anywhere. Firefox and Chromium are not prompting for integration. I tried re-installing both browsers/webapps plugin of each, but no luck. Out of curiousity, I tried to install unity-webapps-preview through terminal, apt-get reported that this operation is going to need 127mb. After installation, restarting session, nothing. I re-ran the unity-webapp-preview in terminal and SURPRISINGLY it again asked me that this operation is going to need 58mb. After Installation, nothing. Firefox is showing the unity-webapp plugin in Extensions but in Preferences there is noting like Unity settings or options for exceptions in General tab (as I seen in some threads). Chromium is not even showing the plugin in Extensions nor in the settings. Really need help. I know there is a reported bug but it is mostly about the complains that the webapps are not working as they should but in my case they don't seem to exist. EDIT: The out put of gsettings list-recursively | grep webapp is: com.canonical.unity.webapps allowed-domains @as [] com.canonical.unity.webapps dontask-domains @as [] com.canonical.unity.webapps index-update-time 43200 com.canonical.unity.webapps integration-allowed true com.canonical.unity.webapps preauthorized-domains ['amazon.ca', 'amazon.cn', 'amazon.com', 'amazon.co.uk', 'amazon.de', 'amazon.es', 'amazon.fr', 'amazon.it', 'www.amazon.ca', 'www.amazon.cn', 'www.amazon.com', 'www.amazon.co.uk', 'www.amazon.de', 'www.amazon.es', 'www.amazon.fr', 'www.amazon.it', 'one.ubuntu.com']

  • Program to Hide/show Given window with hotkey?

    - by Wayne Werner
    Hi, I'm fairly sure this program exists, but I don't remember what it was called. There are a few drop-down terminal programs (guake, yakuke, tilde), and I've been a fan of guake for a while. However, since I discovered GNU Screen I've been more interested in using Eterm. But I would like to make it dropdown/hide on keypress, similar to the way Guake does. I remember at some point that someone mentioned a program that allowed you to do similar things with basically any other window. Unfortunately my time spent googling around for terms like "show/hide any terminal ubuntu" have been met with stupid Windows search engine spam. Any clue where I could find the program I'm looking for? Thanks!

  • Can't specify window's class in CCSM's Place Windows

    - by Anto
    Following this method, I wanted to "place" some of my windows on specific viewports. For instance, I want Xchat to always start on my top right viewport (x=2, y=1). But after I have set everything up and clicked the "Close" button to validate it (I don't have any other action button, like "OK" or "Apply"), the only thing that get saved up are the viewport X and Y coordinates. The window class (in my case class=Xchat) remains empty. This bug only occurs in the "Windows with fixed viewport" section; it works well in the "Windows with fixed placement mode", for instance. How can I solve or circumvent this issue ?

  • Run programs that require a window manager, on the CLI

    - by Twitchy
    Is there any way I can run a game server (MW3) under wine without requiring a window manager present? Currently to run windows only game servers on my Ubuntu box, I have to start them using RDP access as this creates a X session which the program (which has its own GUI). This is a pain as it cannot be automated (or can it?) on start up. What I would rather is some sort of X session emulator that pulls the console output of the program into the CLI so that I can automate server start ups. Is there any program or method that can do this?

  • Unity doesn't work

    - by Budda
    Yesterday I've implemented the code: CustomerProductManager productsManager = container.Resolve<CustomerProductManager>(); It was compilable and working. Today (probably I've modified something I am constantly getting the error: The non-generic method 'Microsoft.Practices.Unity.IUnityContainer.Resolve(System.Type, string, params Microsoft.Practices.Unity.ResolverOverride[])' cannot be used with type arguments My collegue has the same source code and doesn't have same error. Why? How to resolve the problem? P.S. line "using Microsoft.Practices.Unity;" is present in usings section. I've tried to replace generic version with non-generic one: CustomerProductManager productsManager = (CustomerProductManager)container.Resolve(typeof(CustomerProductManager)); And got another error: No overload for method 'Resolve' takes '1' arguments It seems like one of the assemblies is not referenced.. but which one? I have 2 of them referenced: 1. Microsoft.Practices.Unity.dll 2. Microsoft.Practices.ServiceLocation.dll P.P.S. I've saw similar problem http://unity.codeplex.com/WorkItem/View.aspx?WorkItemId=8205 but it is resolved as "not a bug" Any thought will be helpful

  • Using generics in Unity ... InvalidCastException

    - by Sunny D
    Hi, My interface definition is: public interface IInterface where T:UserControl My class definition is: public partial class App1Control : UserControl, IInterface The unity section of my app.config looks as below: <unity> <typeAliases> <typeAlias alias="singleton" type="Microsoft.Practices.Unity.ContainerControlledLifetimeManager, Microsoft.Practices.Unity" /> <typeAlias alias="myInterface" type="MyApplication.IInterface`1, MyApplication" /> <typeAlias alias="App1" type="MyApplication.App1Control, MyApplication" /> </typeAliases> <containers> <container> <types> <type type="myInterface" mapTo="App1" name="Application 1"> <lifetime type="singleton"/> </type> </types> </container> </containers> </unity> The app runs fine but, the following code gives a InvalidCastException container.Resolve<IInterface<UserControl>>("Application 1"); The error message is : Unable to cast object of type 'MyApplication.App1Control' to type 'MyApplication.IInterface`1[System.Windows.Forms.UserControl]' I believe there is a minor mistake in my code ... but am not able to figure out what. Any thoughts?

  • Unable to step into interface implementation configured by unity application block

    - by Rahul
    I have configured a set of interface implementations with EntLib. unity block. The constructor of implementation classes work fine as soon as I run the application: 1. The interface to implement when I run the application the cctor runs fine, which shows that unity resolution was successful: But when I try to call a method of this class, the code just passes through without actually invoking the function of the implemented class: Edit: Added on June 11, 2012 Following is the Unity Configuration I have. (This is all the unity configuration I am doing) public class UnityControllerFactory : DefaultControllerFactory { private static readonly IUnityContainer container; private static UnityControllerFactory factory = null; static UnityControllerFactory() { container = new UnityContainer(); UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity"); section.Configure(container); factory = new UnityControllerFactory(); } public static UnityControllerFactory GetControllerFactory() { return factory; } protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { return container.Resolve(controllerType) as IController; } } I am unable to step into this code and the implementation simply skips out without executing anything. What is wrong here?

  • Applying Unity in dynamic menu

    - by Rajarshi
    I was going through Unity 2.0 to check if it has an effective use in our new application. My application is a Windows Forms application and uses a traditional bar menu (at the top), currently. My UIs (Windows Forms) more or less support Dependency Injection pattern since they all work with a class (Presentation Model Class) supplied to them via the constructor. The form then binds to the properties of the supplied P Model class and calls methods on the P Model class to perform its duties. Pretty simple and straightforward. How P Model reacts to the UI actions and responds to them by co-ordinating with the Domain Class (Business Logic/Model) is irrelevant here and thus not mentioned. The object creation sequence to show up one UI from menu then goes like this - Create Business Model instance Create Presentation Model instance with Business Model instance passed to P Model constructor. Create UI instance with Presentation Model instance passed to UI constructor. My present solution: To show an UI in the method above from my menu I would have to refer all assemblies (Business, PModel, UI) from my Menu class. Considering I have split the modules into a number of physical assemblies, that would be a dificult task to add references to about 60 different assemblies. Also the approach is not very scalable since I would certainly need to release more modules and with this approach I would have to change the source code every time I release a new module. So primarily to avoid the reference of so many assemblies from my Menu class (assembly) I did as below - Stored all the dependency described above in a database table (SQL Server), e.g. ModuleShortCode | BModelAssembly | BModelFullTypeName | PModelAssembly | PModelFullTypeName | UIAssembly | UIFullTypeName Now used a static class named "Launcher" with a method "Launch" as below - Launcher.Launch("Discount") Launcher.Launch("Customers") The Launcher internally uses data from the dependency table and uses Activator.CreateInstance() to create each of the objects and uses the instance as constructor parameter to the next object being created, till the UI is built. The UI is then shown as a modal dialog. The code inside Launcher is somewhat like - Form frm = ResolveForm("Discount"); frm.ShowDialog(); The ResolveForm does the trick of building the chain of objects. Can Unity help me here? Now when I did that I did not have enough information on Unity and now that I have studied Unity I think I have been doing more or less the same thing. So I tried to replace my code with Unity. However, as soon as I started I hit a block. If I try to resolve UI forms in my Menu as Form customers = myUnityContainer.Resolve(); or Form customers = myUnityContainer.Resolve(typeof(Customers)); Then either way, I need to refer to my UI assembly from my Menu assembly since the target Type "Customers" need to be known for Unity to resolve it. So I am back to same place since I would have to refer all UI assemblies from the Menu assembly. I understand that with Unity I would have to refer fewer assemblies (only UI assemblies) but those references are needed which defeats my objectives below - Create the chain of objects dynamically without any assembly reference from Menu assembly. This is to avoid Menu source code changing every time I release a new module. My Menu also is built dynamically from a table. Be able to supply new modules just by supplying the new assemblies and inserting the new Dependency row in the table by a database patch. At this stage, I have a feeling that I have to do it the way I was doing, i.e. Activator.CreateInstance() to fulfil all my objectives. I need to verify whether the community thinks the same way as me or have a better suggestion to solve the problem. The post is really long and I sincerely thank you if you come til this point. Waiting for your valuable suggestions. Rajarshi

  • How to configure Unity/Compiz in 12.04 so that Update Manager opens maximized w/screen bigger than 1024×600?

    - by Jani Uusitalo
    In Precise, window auto-maximize is disabled on monitors with a resolution above 1024 × 600 [1]. I have a bigger resolution, but I prefer maximized windows anyway. I want Update Manager to start maximized. What I've tried so far: In Compiz Config Settings Manager, I have Place Windows activated and 'Windows with fixed placement mode' has windows matching the rule "(name=gnome-terminal) | (name=update-manager)" set to 'Maximize'. With this, Gnome Terminal starts maximized, Update Manager does not. In Compiz Config Settings Manager, I have set a Window Rules [2] rule to match "name=update-manager". Irregardless of any rules set or not, activating Window Rules results in not being able to bring out Unity Launcher anymore, Alt+Tab window switching becoming slow or nonfunctional entirely and the screen sporadically freezing completely. Not a viable option apparently. I've installed Maximus [3] and started it. Update Manager ignores it (or vice versa). I've not tried devilspie and would prefer not to. Having to configure something external for this would seem stupidly redundant with (the no-brainer) Maximus and all these Compiz options already available. I just can't seem to make them work.

  • Can GMod/SFM models be converted to Unity GameObjects?

    - by Supuhstar
    Someone made a suite of GMod/SFM models available for free for people making games and videos in GMod and SFM. These are of type .dmx, .dx80.vtx, .dx90.vtx, .mdl, .phy, .sw.vtx, .vvd, .vmt, and .vtf. I fon't use GMod or SFM, so I don't know what these are, thus making it hard for me to manually convert them. Is there any way to change these into files Unity can recognize and use? I'd like to have an easy step from converting them, but I would also accept instructions on how to export them to generic mesh/skeleton/texture files, and then how to import and combine these in Unity.

  • How can I edit/create new launcher items in Unity by hand?

    - by Ike
    Will Unity allow making custom launcher icons from .desktop files or via menu editing system? (Right now the launcher doesn't give the option to "keep in launcher" on all programs. For some programs I use, I have to make custom launchers or .desktop files. For instance, daily blender builds are generally just folders with an executable. In basic gnome or kde, I can make a new menu entry with the menu editing system. Then, I can also add it to docky either from the menu or by dragging a .desktop file to it. Unity launcher doesn't support drag and drop, so thats not a bug or anything, but when i open a .desktop file, it has unpredictable results. Most time it will not have"keep in launcher". Sometime it will have a pinnable item without the .desktop's icon, and if i pin the item to the launcher, it will not call upon the program again after closing it. I've also gotten it to just work with a .desktop file for "celtx".

  • How to reset settings when Unity won't finish booting?

    - by Emre
    I have a new 12.04 installation and I messed things up after trying to move /home to an NTFS partition, which I later learned was a bad idea. I removed references to the NTFS partition on fstab and created new users on the ext4 / partition. Now I can't get Unity to start up properly for any user. I get the GUI with only three Launch icons (none of which are clickable) and no bar at the top. The keyboard seems to the nonfunctional after I enter my credentials. The interesting thing is that I can boot when I go through recovery mode and select resume. I wonder whether I am creating the new users properly. What is the correct protocol for doing so in order to ensure that they can run Unity?

  • Will Unity allow users to change the color/appearance of the top-Panel?

    - by Sam
    I'm very excited by the functional design principles and keyboard shortcuts that are being implemented for Unity. And function of use is more important to me than looks. However, after experiencing the aesthetic beauty of the display of the top panel in gnome-shell, I was wondering if users would be able to alter the color of Unity's top panel? IMHO it does not look as good as the gnome-shell implementation (or mac OS X/iPad). I think if an alternate color/appearance were chosen for the panel, it would make a big difference aesthetically. Is there a way to make it Black like gnome-shell? Or are the color choices limited to theme-designs as pointed out in this answer? For efficiency and clarity, the Panel should be better differentiated from application controls. The panel should be a different color because it has a "constant (always present) state," unlike application controls. For contrast and easy-recognition, I would like to make the Panel black (like gnome-shell) but make the application controls (e.g., those of Firefox) "Inverted"
