  • Change color of Date and Weather app in Ubuntu 12.04 & Mate

    - by haunted85
    I have recentely installed Ubuntu 12.04 and as I am a truly Gnome 2 lover I also switched from Unity to Mate. The font color of the Weather/Date applet is barely visible so I was wondering how I can change it. I Already tried to explore all the options shown in the menu when I right-click on the applet, but apparently there's no such feature. So is there anything I could do in order to customize the font color in order to make the text more readable?

  • User login cycles

    - by Doug Brown
    Just install 12.04-64bit and while I can login using the guest login, I cannot with my user login: it just cycles back to the login screen. I have performed the sequence of apt-get update/upgrade and install of the nvidia-current driver, but got back that it was already in use. The password appears to be recognized, as wrong one results in an error. Have also tried switching to the 2D Unity, without other results.

  • Can DrawIndexedPrimitives() be used for drawing a loaded model mesh-wise?

    - by Afzal
    I am using DrawIndexedPrimitives() for drawing a loaded 3D model by drawing each mesh part, but this process makes my application very slow. This is perhaps because of a very large number of vertex/index buffer data created in video memory. That is why I am looking for a way to use the same method for each model mesh instead. The problem is that I don't know how I will set the textures of that mesh. Can anyone offer me some guidance?

  • Switching from an Ubuntu derivative to original Ubuntu

    - by SteliosSk
    I installed Zorin 6 (based on Ubuntu 12.04), because I like all the whistles it has (plymouth screen,compiz effects,installed codecs, sound themes, etc.). I miss though the modern and futuristic unity environment (launcher, dash, HUD, indicators etc.). Is there a way to switch from Zorin to Ubuntu 12.04.1 LTS and keep all these effects? Or What additional software should I install in an Ubuntu clean install to add the effects Zorin has (plymouth, compiz effects, sounds, audio and video codecs etc.)

  • Why do the Escape and Enter keys not always do the right thing in dialog boxes?

    - by Michael Goldshteyn
    Why is it that when a dialog pops up, the Escape key doesn't always cancel it and the Enter key doesn't always press the default button? Shouldn't this be a standard across all dialog boxes in all applications? I have gotten into the habit of pressing Escape to cancel a dialog and Enter to confirm it, but applications (and especially KDE, GNOME and Unity in many many cases) seem to ignore my wishes. What is the problem? Is consitency too much to ask?

    I recently upgraded to 11.10 from 11.04, everything went fine, still hate unity and all that. But my battery status is not showing up at all, even on my laptop. There isn't even any spaces for it, there is only the Mail Icon, Wirelesss Icon, Sound, Time, [username] and Power. I have tried several different things to get it, but I am at a loss. Please help I've already tried to install indicator-power and it is installed.

  • Where does a "Technical Programmer" fit in, and what does the title mean? [closed]

    - by Mike E
    Was: "What is a 'Technical Programmer'"? I've noticed in job posting boards a few postings, all from European companies in the games industry, for a "Technical Programmer". The job description was similar, having to do with tools development, 3d graphics programming, etc. It seems to be somewhere between a Technical Artist who's more technical than artist or who can code, and a Technical Director but perhaps without the seniority/experience. Information elsewhere on the position is sparse. The title seems redundant and I haven't seen any American companies post jobs by that name, exactly. One example is this job posting on gamedev.net which isn't exactly thorough. In case the link dies: Subject: Technical Programmer Frictional Games, the creators of Amnesia: The Dark Descent and the Penumbra series, are looking for a talented programmer to join the company! You will be working for a small team with a big focus on finding new and innovating solutions. We want you who are not afraid to explore uncharted territory and constantly learn new things. Self-discipline and independence are also important traits as all work will be done from home. Some the things you will work with include: 3D math, rendering, shaders and everything else related. Console development (most likely Xbox 360). Hardware implementations (support for motion controls, etc). All coding is in C++, so great skills in that is imperative. Revised Summarised Question: So, where does a programmer of this nature fit in to software development team? If I had these on my team, what tasks am I expecting them to complete? Can I ask one to build a new level editor, or optimize the rendering engine? It doesn't seem to be a "tools programmer" which focuses on producing artist tools, often in high-level languages like C#, Python, or Java. Nor does it seem to be working directly on the engine, nor a graphics programmer, as such. Yet, a strong C++ requirement, which was mirrored in other postings besides this one I quoted. Edited To Add As far as it being a low-level programmer, I had considered that but lacking from the posting was a requirement of Assembly. Instead, they tend to require familiarity with higher-level hardware APIs such as DirectX, or DirectInput. I wasn't fully clear in my original post. I think, however, that Mathew Foscarini has it right in his answer, so barring someone who definitely works with or as a "Technical Programmer" stepping in to provide a clearer explanation, I'll go with that. A generalist, which also fits the description of a more-technical-than-artist TA.

  • Dual nVidia GPUs (3 monitors) not working in 11.10

    - by jasonmclose
    after searching I have not found a solution. I have 2 nvidia quadro 295 cards with 3 monitors but I can not extend twinview across multiple GPUs. I have the most recent nvidia proprietary drivers installed, and they work fine for the single GPU / dual monitors. I tried using xinerama, but without success. I don't mind switching to the nouveau drivers if that would handle my multiple monitors, although I would like to continue to use unity and compiz if i can).

  • How to design the scenarios in a platform game?

    - by ReyLitch
    I am developing a 3D platform game like Metroid Fusion with XNA. I have many classes for different elements as models, game screens, postprocessing and so on. Now I want to start designing the scenarios but I think that the scenarios needed in a platform game are not as conventional (by conventional I say something like this). I am very lost and not know where to start and how to structure it. Thanks in advance.

  • Ubuntu 12.10 on Acer Aspire S3: screen resolution

    - by sashkello
    I'm new to linux and recently installed Ubuntu 12.10 alongside Windows on my laptop. Initially 3D screen effects (i.e., Docky) were not working and I tried different things like installing and reinstalling nvidia-current, compiz etc... Now I think I messed up the display drivers completely... Although all the effects are now working, I can't get any screen resolution other than 640x480. Can anyone please tell me how to find out exactly what's wrong and ways of fixing it?

  • How do I find out which version and derivative of Ubuntu is right for my hardware in terms of minimal system requirements?

    - by con-f-use
    For a given hardware configuration, how do I find out if Ubuntu will run on it? What considerations should I take into account when choosing an Ubuntu version and flavour such as: Xubuntu with a lighter desktop than the usual Gnome and Unity Lubuntu with the even lighter LXDE desktop Obviously Ubuntu does not run on some processor architectures. So how do I go about choosing the right version and derivate. How can I find out the minmal system requirements?

  • Missing resolutions on ubuntu 11.10 fresh install

    - by Sean Marshall
    Today I installed Ubuntu 11.10 for the first time on my computer. My Monitor's resolution is 1280x1024, but the only resolutions in display are "1024x768 (4:3)" and "800x600 (4:3)". I installed all updates, There is nothing in additional drivers and still nothing. I want to set the resolution to 1280x1024. How do I check my graphic card name? By the way Unity 3d is working and compiz effects are working super fast.

  • Movement prediction for non-shooters

    - by ShadowChaser
    I'm working on an isometric (2D) game with moderate-scale multiplayer - 20-30 players. I've had some difficulty getting a good movement prediction implementation in place. Right now, clients are authoritative for their own position. The server performs validation and broad-scale cheat detection, and I fully realize that the system will never be fully robust against cheating. However, the performance and implementation tradeoffs work well for me right now. Given that I'm dealing with sprite graphics, the game has 8 defined directions rather than free movement. Whenever the player changes their direction or speed (walk, run, stop), a "true" 3D velocity is set on the entity and a packet it sent to the server with the new movement state. In addition, every 250ms additional packets are transmitted with the player's current position for state updates on the server as well as for client prediction. After the server validates the packet, it gets automatically distributed to all of the other "nearby" players. Client-side, all entities with non-zero velocity (ie/ moving entities) are tracked and updated by a rudimentary "physics" system - basically nothing more than changing the position by the velocity according to the elapsed time slice (40ms or so). What I'm struggling with is how to implement clean movement prediction. I have the nagging suspicion that I've made a design mistake somewhere. I've been over the Unreal, Half-life, and all other movement prediction/lag compensation articles I could find, but they all seam geared toward shooters: "Don't send each control change, send updates every 120ms, server is authoritative, client predicts, etc". Unfortunately, that style of design won't work well for me - there's no 3D environment so each individual state change is important. 1) Most of the samples I saw tightly couple movement prediction right into the entities themselves. For example, storing the previous state along with the current state. I'd like to avoid that and keep entities with their "current state" only. Is there a better way to handle this? 2) What should happen when the player stops? I can't interpolate to the correct position, since they might need to walk backwards or another strange direction if their position is too far ahead. 3) What should happen when entities collide? If the current player collides with something, the answer is simple - just stop the player from moving. But what happens if two entities take up the same space on the server? What if the local prediction causes a remote entity to collide with the player or another entity - do I stop them as well? If the prediction had the misfortune of sticking them in front of a wall that the player has gone around, the prediction will never be able to compensate and once the error gets to high the entity will snap to the new position.

  • Xubuntu: Screen idle-dims after lock+new login although not idling

    - by unhammer
    I set my screen to dim after 2 minutes idling on battery in XFCE power settings. If I lock and click new login, and log in as another user, the screen will dim after 2 minutes even though that second user is active. Is there some setting or workaround for this? It feels like a bug, but I have no idea what program or combination of programs would be responsible … (I don't know if this affects Unity users or not.)
