  • Gnome 3 - Old fashioned buttons and menus

    - by vigs1990
    I've upgraded to Gnome 3 and the problem I'm facing is that when I restart, sometimes the menus and buttons look old-fashioned like this: whereas sometimes, it looks modern and neat like this: Notice the differences between the two: here are a few differences: The menu bar (notice the difference in fonts, dark grey color of Snapshot1 vs the light grey color in Snapshot2 in the background) The file navigation bar bellow the menu bar (notice the 'Home' button there and also the left arrow button) The left-hand side navigation bar (font, background color and color of selected folder) The old style look effects the GTK aspects of the interface, such as the menu, buttons, mouse pointer etc. Another observation is that changing the GTK themes does using gnome-tweak-tool when the old style look is loaded does NOT work. However, this works when the regular look is loaded. How can I ensure that the old-fashioned look does not load on boot?

  • SpriteBatch.Begin() making my model not render correctly

    - by manning18
    I was trying to output some debug information using DrawString when I noticed my model suddenly was being rendered like it was inside-out (like the culling had been disabled or something) and the texture maps weren't applied I commented out the DrawString method until I only had SpriteBatch.Begin() and .End() and that was enough to cause the model rendering corruption - when I commented those calls out the model rendered correctly What could this be a symptom of? I've stripped it down to the barest of code to isolate the problem and this is what I noticed. Draw code below (as stripped down as possible) GraphicsDevice.Clear(Color.LightGray); foreach (ModelMesh mesh in TIEAdvanced.Meshes) { foreach (Effect effect in mesh.Effects) { if (effect is BasicEffect) ((BasicEffect)effect).EnableDefaultLighting(); effect.CurrentTechnique.Passes[0].Apply(); } } spriteBatch.Begin(); spriteBatch.DrawString(spriteFont, "Camera Position: " + cameraPosition.ToString(), new Vector2(10, 10), Color.Blue); spriteBatch.End(); GraphicsDevice.DepthStencilState = DepthStencilState.Default; TIEAdvanced.Draw(Matrix.CreateScale(0.025f), viewMatrix, projectionMatrix);

  • Good practices in screen states management?

    - by DevilWithin
    I wonder what are the best ways to organize different screens in a game? I am thinking of it like this: Inheriting a base State class, and overriding update and render methods, to handle the current screen. Then, under certain events a StateManager is able to activate another Screen State, and the game screen changes as only the current State is rendered. On the activation of a new screen, effects like fading could be added, and also the same goes for its deactivation. This way a flow of screen could be made. By saying when A ends, B starts, allowing for complex animations etc. Toughts?

    - by Gaurav Sharma

Now whatever little I know , this may be related with graphics diver either they are not present or the graphic card is not turned on. Can some one help with this. And yeah i tried ubuntu 13.10 that worked fine but it has some bugs. and yeah please pardon me for my bad English.

  • Display monitor info via command line

    - by icyrock.com
    Is there a way to query monitor information from command line? For example, get monitor model, similar to e.g. what lspci does for graphic card info, or whether it's currently on or off, things like that. If possible, what kinds of basic information such as the above can be easily gathered? For example, is it possible to determine if monitor is in portrait or landscape position? Or if it has built-in speakers or not? Command line is the preference, but if there's a GUI method, I'd like to hear about it, too.

  • How can I create a dynamic site that is still search-bot friendly?

    - by zuko
    If I want to have a slide effect between pages. You click a link, it is loaded off to the side and then slides in (pushing the old page off the other side). I can imagine using jQuery to do the PHP and the effects... but how do I do something like this that gracefully degrades for users without Javascript, including bots? Possibly more problematic: what if I wanted to have a sort of mural background across the site, perhaps with a parallax scrolling effect, and sliding to other pages reveals more of the, possibly giant image? Again, I can imagine how to do this with lots of fancy jQuery and PHP but it would heavily rely on those. How can I gracefully degrade in a situation like that? Any pointers, articles or books would be greatly appreciated. I keep trying to search for answers but I just get a lot of "theory"-based, unhelpful blogs.

  • How can I customize an FPS game?

    - by monoceres
    I want to create a customized (modded) fps game where I can change the look and feel of the game to match my intended theme. Some of the things I would like to do: Create a custom map (terrain). Add custom sound effects Change AI (For example, running away instead of actively looking for combat). Change menus and add some storyboard. Script events in game (like a countdown until game over) Change the models of the NPC's. What options do I have? Is there any platform/game/engine/whatever that allows one to do the things above in a reasonable way? I work as a programmer so I'm not afraid of coding some part of the project, but to save time it would be nice to work in some high-level way (like scripting or configuration files).

  • Where can I learn image processing? [on hold]

    - by Little Child
    I am learning image processing on my own and I have managed to teach myself a fair few things like: Making images grayscale using 3 different methods Applying a 'pixellate' filter Applying a 'pointillize' filter Make images out of lines Now, I want to take my knowledge further but I do not know how. Adding more information: I am interested in making software like Photoshop or Gimp (although it won't be half as powerful as these 2). So, I want to learn to apply various creative effects to an image. Can someone please suggest resources for this??

What would be the best course of action to find help?

  • Tunnels in pseudo 3D racing game

    - by Nicholas
    How would one go about doing tunnels in a pseudo 3D racing game ? The main problem I have at the moment is perspective - I cant think of a way, beyond having to Z sort the sprites and tunnel coordinates, so that vehicles are displayed in front of the tunnel entrance and somehow block the display when out of site. I would like my tunnels to be used on both flat, curved and hills and slopes. The tunnel enterance/exit is made up of 3 separate graphics, (left, right and top), whilst inside the tunnel it is just one line graphic along the top (the idea being its supposed to be a set distance above the current vertical road position). As you can see from the picture, the vehicles are still being rendered whilst in the tunnel. I've converted the Code Incomplete road system to GLBasic.

  • How to get audio spectrum analysis?

    - by Mrwolfy
    I need to find or create a tool that analyzes the audio spectrum of a sound file (like a .wav or .mp3). I need to output the "volume" or power of x number of frequency bands and output the data as text. This will be used to produce a visualization, a graphic equalizer like you'd see on a stereo. I am currently looking at python to do it. My question is are there some tools out there that would do this (signal processing), like math works or others? I don't have any experience with them so any advice would be appreciated.

  • How can I make my game more popular without paying money?

    - by Marlon Drescher
    I am a game designer, software developer, composer and graphic artist and made the 3D Hack 'n Slay MMO Forgotten Elements on my own. It's playable at open Beta and will be released at the end of the year. I used Plain Old JAVA, JPCT 3D Engine, Tomcat Webserver and Blender 3D / Gimp to manage all the tasks. I developed the whole game from scratch. For me the hardest task in this challenge is probably the whole thing about marketing and advertisement. Because it is a independent project and I am the only person working on it, there is no money I could invest for making advertisement. But anyhow... How could it be possible to make this game more popular? What would you suggest me?

  • What is the right option of programming languages and tools for building our website?

    - by Goma
    We are 3 persons trying to build a large website which will be available in 3 languges. However, we will start with one language and with small idea then we are going to improve it and make it larger! What do you think the best tools and language that we should use? We are caring alot about the speed of loading the pages and tools that provide excellent qulaity with cheaper fees. Edit: We are graphic designers, so we did not choose the programming language yet. But we studied computer science and we have an idea but we found that this is the best place to ask the question and expect the right answer from you. Should we use ASP.NET for example? or PHP? We do not want an expesive option that will cost us alot in the future and we do not want to change the technology at least for the first 5 years. Thanks!

  • What effect does using itemprop="significantLinks" on anchors have for SEO?

    - by hdavis84
    So as I've described in a previous post about span tags within head tags, I'm practicing application of microdata via http://schema.org. Anyone who's browsed the documentation there knows that there's a lot of need for improvement for more clear understandings on use for each property. My question on this post is more about the "significantLinks" property and how it effects SEO for on page, in content anchored text. Does anyone have any more information regarding whether its good to use for link optimization? I understand what schema.org means that it's to be used on "non-navigational links" and those links should be relevant to the current page's meaning. But will using this property hurt SEO or make SEO better for each page? Thanks in advance, as by answering this with accurate information you are helping not just me, but many people who are trying to make their customers more successful through helping their rank for relevant keywords to their business, bringing them more search engine traffic.

  • Brightness control not working on HP Pavilion dm3t (Intel GMA 4500MHD)

    - by James
    Hey all, I picked up an hp dm3t laptop with intel HD graphics and installed ubuntu 10.10 64 bit on it. It works great -- the only problem is that the brightness controls on the keyboard don't work. The brightness is always at full. When I try to adjust it down, the indicator graphic indicates that it's going down but the actual brightness doesn't change. Is there anything that I can try to make this work? I'd really appreciate any help. I asked this on superuser.com and someone commented that I should play around with the intel hd drivers. I'm a total noob -- how do I do that? What else can I try? I really don't want to go back to windows.

  • How is Basic Physics applied in CS/SE?

    - by Wulf
    What basic physics principles do software engineers and/or computer scientists use to help solve specific or common problems? The first one that came to my head was creating a Physics engine for a game; physics is involved, as it requires knowledge of: Forces and Motion: Kinematics, Dynamics, Circular Motion However, I need another example, but haven't come across one that involves basic physics. Please consider the following basic physics (grade 12 level) concepts: Energy and Momentum: Work and Energy, Momentum and Collisions, Gravitational and Celestial Mechanics Electric, Gravitational & Magnetic Field: Electric Charges and Electric Field, Magnetic Fields and Electomagnetism The Wave Nature of Light: Waves and Light, Wave Effects of Light Matter-Energy Interface: Einstein’s Special Theory of Relativity, Waves, Photons and Matter, Radioactivity and Elementary Particles I will be happy with any response; Keywords for google, names of methods like raycasting, etc.

  • Ubuntu 12.04 LTS - Black Screen at boot After changing Nvidia Driver

    - by nDman
    2 days ego i updated my Ubuntu 12.04 LTS to latest updates but i ignored Grub Updating because I thought it will clear my grub settings (I'm so noob!). After restart every things was right, the Ubuntu started normally and every things was working well except graphic which had problem before update. I had the experimental driver before but I changed it to the current-update version. After restart Ubuntu stock on black screen. I tried to reinstall Nvidia driver from recovery but it not worked. Then i used Update Grub in recovery, it not worked too but i see this line on screen at boot: at this time it stops and keyboard not working, but when I push the power button it shows these lines and it will shutdown. OK finally I made it start with older kernel (3.5.0-28-generic). Now how can I keep this kernel or fix Ubuntu to work with new kernel? Should I reinstall Nvidia driver? Which version should I use?

  • Unity3D or UDK or OPENGL from scratch?

    - by Legolas
    I am just very confused which I should choose in terms of high end game development. The application that I am designing is pretty simple, requires some 3D, and some effects. I am looking at a game similar to ping pong, but with high textures and graphics. I will just need web services to submit high scores. From my description, you can see that its pretty straight forward and I am confused whether I should use Unity3D or UDK or write the entire application myself with openGL (which will take a lot of time though). If you had faced this dilemma before, and chose for a particular graphics engine, please provide your suggestions and reasons as to why that was better. It would be helpful. Also, how can this affect in terms of investment and revenue ?

  • Ubuntu won't wake after pm-suspend

    - by Matus
    i have ubuntu 12.04 on my Zotac AD-02. Problem is when i run pm-suspend. zotac goes to sleep (it shows red led, and green light is flashing) but when i send magic packet to WOL it hangs ... it stops flashing and LED is green as its turned on but SSH wont run and it won't react to mouse or anything. I've read that sometimes it has something to do with graphics. It is mainly for DLNA and PLEX so i don't use any graphic component so if there is the problem tell me how to disable it :) is there some log or anything i can post? im fairly good at bash but not at all in ubuntu or debian. so i can't find any log. Thanks EDIT: here is lscpi if it helps
