  • Light mask map and camera for static lights in XNA Platformer

    - by JiminyCricket
    Using the example for some basic light maps found here : http://blog.josack.com/2011/07/xna-2d-dynamic-lighting.html, I've managed to create a lightmap texture using individual lightmaps and display it over a 2D tiled world as in the Platformer example. I'm using the very basic 2D camera example as found here : http://www.david-amador.com/2009/10/xna-camera-2d-with-zoom-and-rotation/, and the problem is that the lightmap texture scrolls with the player sprite. This looks pretty good and would be excellent for lighting the player sprite as it moves. But, I also want to be able to place static lights (or some initial position for the lights) that do not move with the player or camera. When I turn off the camera or give it a static position, it works as a series of static lights so I believe it's probably caused by the camera transformation matrix following the player around. I'm using RenderTarget2Ds, one for the main game screen after all the backgrounds and tiles are rendered, and one for the "lightmap" which consists of a black background and a bunch of lighting textures which are merged with it using additive blending. For now, I'm doing all of this in PlatformerGame.cs where the camera transformation and position is set and the level.Draw() call is made. I can't figure out how to separate the drawing of the lightmap and the camera following the player. I was thinking it would be better to render the shadows and lighting directly in the drawing of the level itself, but I'm not sure how to do that either because this technique requires RenderTarget2Ds and calling SpriteBatch.Begin()/End().

  • WLS Console Timeout

    - by john.graves(at)oracle.com
    The WebLogic console timeout is a great feature for security, yet a horrible feature during development.  Logging in over and over again gets to be annoying.  This is very easy to change, but I would never do this on a production system!   Find the WebLogic consoleapp weblogic.xml file.  This is typically in your WL_HOME/server/lib/consoleapp/webapp/WEB-INF/ directory. Edit the weblogic.xml file: Update the section shown and increase the timeout-secs.  I just throw an extra zero at the end giving me ten full hours of fun!!!: <session-descriptor> <timeout-secs>36000</timeout-secs> <invalidation-interval-secs>60</invalidation-interval-secs> <cookie-name>ADMINCONSOLESESSION</cookie-name> <cookie-max-age-secs>-1</cookie-max-age-secs> <cookie-http-only>false</cookie-http-only> <url-rewriting-enabled>false</url-rewriting-enabled> </session-descriptor> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }

  • How could I change the colour of the menu font in Lubuntu?

    - by cipricus
    I use Lubuntu 12.04 and I have become obsessed with the looks of it! There is a type of themes that I especially want to use (flat, light), all related to the Elegant brit theme. On my desktop it looks like: As I want to replace the dominating orange with blue, I would prefer even more the theme Elegant Brit re-Revisited The problem is that both of them have a problem with my system tray, a white background appears: A theme that is almost identical to the orange one, but has no problem with the system tray is called Elegant Blackle. I have tried to use this one and replaced the gtk2 folder in its main folder with the gtk2 folder from Elegant Brit re-Revisited. The result is an improvement for me, as I have eliminated a part of the orange stuff with a decent blue :). The orange now appears only with the gtk3 apps, which is rather amusing. Migrating also the gtk3 folder from the blue to the orange theme would bring the sys tray problem too: it is something related to that gtk3 folder. But this is another matter. Now I have something very close to what I want. But I especially would like to have a feature that was present in the Elegant Blackle theme and now is gone as its gtk2 folder was replaced by that of the blue theme: the black font of the menus, instead of the blueish ones. Could anyone instruct me what is to be changed in the gtk2 folder of the Elegant Brit re-Revisited theme so as to make the menus look like this (like they do in Elegant Blackle with its original gtk2 folder): and not like this? : (on my display this blue is more whitish). An alternative and ideal solution would be knowing how to edit the Elegant Brit re-Revisited theme so as to remove the systray problem or, maybe easier, to edit the orange colour of Elegant Blackle theme to as to be completely replaced by the blue of the other one.

  • dynamic 2d texture creation in unity from script

    - by gman
    I'm coming from HTML5 and I'm used to having the 2D Canvas API I can use to generate textures. Is there anything similar in Unity3D? For example, let's say at runtime I want to render a circle, put 3 initials in the middle and then take the result and put that in a texture. In HTML5 I'd do this var initials = "GAT"; var textureWidth = 256; var textureHeight = 256; // create a canvas var c = document.createElement("canvas"); c.width = textureWidth; c.height = textureHeight; var ctx = c.getContext("2d"); // Set the origin to the center of the canvas ctx.translate(textureWidth / 2, textureHeight / 2); // Draw a yellow circle ctx.fillStyle = "rgb(255,255,0)"; // yellow ctx.beginPath(); var radius = (Math.min(textureWidth, textureHeight) - 2) / 2; ctx.arc(0, 0, radius, 0, Math.PI * 2, true); ctx.fill(); // Draw some black initials in the middle. ctx.fillStyle = "rgb(0,0,0)"; ctx.font = "60pt Arial"; ctx.textAlign = "center"; ctx.fillText(initials, 0, 30); // now I can make a texture from that var tex = gl.createTexture(); gl.bindTexture(gl.TEXTURE_2D, tex); gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, gl.UNSIGNED_BYTE, c); gl.generateMipmap(gl.TEXTURE_2D); I know I can edit individual pixels in a Unity texture but is there any higher level API for drawing to texture in unity?

  • Is it possible to render and style a <title> element from within the <head> of an html document?

    - by Brian Z
    Is it possible to render and style a <title> element from within the <head> of an html document? I thought it was impossible to render information from the <head>, but the system status page for 37signals.com seems to be doing just that - http://status.37signals.com/. If you inspect the element at the very top of the page, the text that reads "37signals System Status", you'll see that the part of the DOM that is generating the text is the <head>'s <title>, and the css is as follows: title { display: block; margin: 10px auto; max-width: 840px; width: 100%; padding: 0 20px; float: left; color: black; text-rendering: optimizelegibility; -moz-box-sizing: border-box; box-sizing: border-box; } Can someone confirm that the <title> info from the <head> is indeed what is being rendered? If so, can someone point to documentation that defines this capability as I have not found any? I have applied the above css to an html document on my local web server using the same browser (chromium, os x 10.8.5) as the 37signals site was viewed on, yet my file did not display the <head>'s <title>.

  • PowerBroker (Likewise-Open) + Ubuntu 13.04 -> 13.10 Upgrade

    - by JoBu1324
    I just upgraded Ubuntu from 13.04 to 13.10, and now I can't log into Active Directory; my system is integrated using PowerBroker Identity Services (PBIS), which used to be called Likewise-Open. So far I have identified the following symptoms: I am able to log in with my credentials via ssh. The screen goes black when attempting log into my account via the login screen. I've tried leaving the domain, purging PBIS, and re-installing the latest version of PBIS. I've been trying the troubleshooting section I found here, but I haven't had any success.

  • Get a culture specific list of month names

    - by erwin21
    A while ago I found a clever way to retrieve a dynamic culture specific list of months names in C# with LINQ. 1: var months = Enumerable.Range(1, 12) 2: .Select(i => new 3: { 4: Month = i.ToString(), 5: MonthName = new DateTime(1, i, 1).ToString("MMMM") 6: }) 7: .ToList(); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } It’s fairly simple, for a range of numbers from 1 to 12 a DateTime object is created (year and day doesn’t matter in this case), then the date time object formatted to a full month name with ToString(“MMMM”). In this example an anonymous object is created with a Month and MonthName property. You can use this solution to populate your dropdown list with months or to display a user friendly month name.

  • ArchBeat Link-o-Rama Top 10 for December 9-15, 2012

    - by Bob Rhubart
    You click, we listen. The following list reflects the Top 10 most popular items posted on the OTN ArchBeat Facefbook page for the week of December 9-15, 2012. DevOps Basics II: What is Listening on Open Ports and Files – WebLogic Essentials | Dr. Frank Munz "Can you easily find out which WebLogic servers are listening to which port numbers and addresses?" asks Dr. Frank Munz. The good doctor has an answer—and a tech tip. Using OBIEE against Transactional Schemas Part 4: Complex Dimensions | Stewart Bryson "Another important entity for reporting in the Customer Tracking application is the Contact entity," says Stewart Bryson. "At first glance, it might seem that we should simply build another dimension called Dim – Contact, and use analyses to combine our Customer and Contact dimensions along with our Activity fact table to analyze Customer and Contact behavior." SOA 11g Technology Adapters – ECID Propagation | Greg Mally "Many SOA Suite 11g deployments include the use of the technology adapters for various activities including integration with FTP, database, and files to name a few," says Oracle Fusion Middleware A-Team member Greg Mally. "Although the integrations with these adapters are easy and feature rich, there can be some challenges from the operations perspective." Greg's post focuses on technical tips for dealing with one of these challenges. Podcast: DevOps and Continuous Integration In Part 1 of a 3-part program, panelists Tim Hall (Senior Director of product management for Oracle Enterprise Repository and Oracle’s Application Integration Architecture), Robert Wunderlich (Principal Product Manager for Oracle’s Application Integration Architecture Foundation Pack) and Peter Belknap (Director of product management for Oracle SOA Integration) discuss why DevOps matters and how it changes development methodologies and organizational structure. Good To Know - Conflicting View Objects and Shared Entity | Andrejus Baranovskis Oracle ACE Director Andrejus Baranovskis shares his thoughts -- and a sample application -- dealing with an "interesting ADF behavior" encountered over the weekend. Cloud Deployment Models | B. R. Clouse Looking out for the cloud newbies... "As the cloud paradigm grows in depth and breadth, more readers are approaching the topic for the first time, or from a new perspective," says B. R. Clouse. "This blog is a basic review of cloud deployment models, to help orient newcomers and neophytes." Service governance morphs into cloud API management | David Linthicum "When building and using clouds, the ability to manage APIs or services is the single most important item you can provide to ensure the success of the project," says David Linthicum. "But most organizations driving a cloud project for the first time have no experience handling a service-based architecture and don't see the need for API management until after deployment. By then, it's too late." Oracle Fusion Middleware Security: Password Policy in OAM 11g R2 | Rob Otto Rob Otto continues the Oracle Fusion Middleware A-Team "Oracle Access Manager Academy" series with a detailed look at OAM's ability to support "a subset of password management processes without the need to use Oracle Identity Manager and LDAP Sync." Understanding the JSF Lifecycle and ADF Optimized Lifecycle | Steven Davelaar Could you call that a surprise ending? Oracle WebCenter & ADF Architecture Team (A-Team) member learned a lot more than he expected while creating a UKOUG presentation entitled "What you need to know about JSF to be succesful with ADF." Expanding on requestaudit - Tracing who is doing what...and for how long | Kyle Hatlestad "One of the most helpful tracing sections in WebCenter Content (and one that is on by default) is the requestaudit tracing," says Oracle Fusion Middleware A-Team architect Kyle Hatlestad. Get up close and technical in his post. Thought for the Day "There is no code so big, twisted, or complex that maintenance can't make it worse." — Gerald Weinberg Source: SoftwareQuotes.com

  • How do I draw anti-aliased holes in a bitmap

    - by gyozo kudor
    I have an artillery game (hobby-learning project) and when the projectile hits it leaves a hole in the ground. I want this hole to have antialiased edges. I'm using System.Drawing for this. I've tried with clipping paths, and drawing with a transparent color using gfx.CompositingMode = CompositingMode.SourceCopy, but it gives me the same result. If I draw a circle with a solid color it works fine, but I need a hole, a circle with 0 alpha values. I have enabled these but they work only with solid colors: gfx.CompositingQuality = CompositingQuality.HighQuality; gfx.InterpolationMode = InterpolationMode.HighQualityBicubic; gfx.SmoothingMode = SmoothingMode.AntiAlias; In the two pictures consider black as being transparent. This is what I have (zoomed in): And what I need is something like this (made with photoshop): This will be just a visual effect, in code for collision detection I still treat everything with alpha 128 as solid. Edit: I'm usink OpenTK for this game. But for this question I think it doesn't really matter probably it is gdi+ related.

  • Functional testing in the verification

    - by user970696
    Yesterday my question How come verification does not include actual testing? created a lot of controversy, yet did not reveal the answer for related and very important question: does black box functional testing done by testers belong to verification or validation? ISO 12207:12208 here mentiones testing explicitly only as a validation activity, however, it speaks about validation of requirements of the intended use. For me its more high level, like UAT test cases written by business users ISO mentioned above does not mention any specific verification (7.2.4.3.2)except for Requirement verification, Design verification, Document and Code & Integration verification. The last two can be probably thought as unit and integrated testing. But where is then the regular testing done by testers at the end of the phase? The book I mentioned in the original question mentiones that verification is done by static techniques, yet on the V model graph it describes System testing against high level description as a verification, mentioning it includes all kinds of testing like functional, load etc. In the IEEE standard for V&V, you can read this: Even though the tests and evaluations are not part of the V&V processes, the techniques described in this standard may be useful in performing them. So that is different than in ISO, where validation mentiones testing as the activity. Not to mention a lot of contradicting information on the net. I would really appreciate a reference to e.g. a standard in the answer or explanation of what I missed in the ISO. For me, I am unable to tell where the testers work belong.

  • nvidia-settings makes one of my dual monitors grey and useless, disables network

    - by Kerrick
    I'm running Ubuntu 12.04 64-bit, Precise Pangolin, with a PNY GTS 250 1GB video card and a monitor plugged into each of the DVI ports. I'm using the proprietary drivers (post-release updates). If I set anything to do with Separate X Screens up in nvidia-settings (and write it to xorg.conf and reboot), my second monitor has a grey background, no menu bar, no ability to have a window on it, the second monitor doesn't get picked up in a screneshot, and if I move my mouse cursor to it it's an ugly black X. Plus, my network is unable to connect to anything. If I subsequently delete /etc/X11/xorg.conf and reboot, everything goes back to working, albeit with a single monitor activated. If I set anything to do with TwinView up in nvidia-settings, my second monitor starts working, but it isn't seen as a second monitor by Ubuntu, so I can't apply color calibration to it separately. Plus, my mouse gets "caught" between the monitors every time I try to move my cursor between the two. What gives? If it helps, this is the xorg.conf that nvidia-settings generates for Separate X Screens.

  • Why doesn't my cube hold a position?

    - by Christian Frantz
    I gave up a previous method of creating cubes so I went with a list to hold my cube objects. The list is being populated from an array like so: #region MAP float[,] map = { {0, 0, 0, 0, 0}, {0, 0, 0, 0, 0}, {0, 0, 0, 0, 0}, {0, 0, 0, 0, 0}, {0, 0, 0, 0, 0} }; #endregion MAP for (int x = 0; x < mapWidth; x++) { for (int z = 0; z < mapHeight; z++) { cubes.Add(new Cube(device, new Vector3(x, map[x,z], z), Color.Green)); } } The cube follows all the parameters of what I had before. This is just easier to deal with. But when I debug, every cube has a position of (0, 0, 0) and there's just one black cube in the middle of my screen. What could I be doing wrong here? public Vector3 cubePosition { get; set; } public Cube(GraphicsDevice graphicsDevice, Vector3 Position, Color color) { device = graphicsDevice; color = Color.Green; Position = cubePosition; SetUpIndices(); SetUpVerticesArray(); } That's the cube constructor. All variables are being passed correctly I think

  • Dependency injection: what belongs in the constructor?

    - by Adam Backstrom
    I'm evaluating my current PHP practices in an effort to write more testable code. Generally speaking, I'm fishing for opinions on what types of actions belong in the constructor. Should I limit things to dependency injection? If I do have some data to populate, should that happen via a factory rather than as constructor arguments? (Here, I'm thinking about my User class that takes a user ID and populates user data from the database during construction, which obviously needs to change in some way.) I've heard it said that "initialization" methods are bad, but I'm sure that depends on what exactly is being done during initialization. At the risk of getting too specific, I'll also piggyback a more detailed example onto my question. For a previous project, I built a FormField class (which handled field value setting, validation, and output as HTML) and a Model class to contain these fields and do a bit of magic to ease working with fields. FormField had some prebuilt subclasses, e.g. FormText (<input type="text">) and FormSelect (<select>). Model would be subclassed so that a specific implementation (say, a Widget) had its own fields, such as a name and date of manufacture: class Widget extends Model { public function __construct( $data = null ) { $this->name = new FormField('length=20&label=Name:'); $this->manufactured = new FormDate; parent::__construct( $data ); // set above fields using incoming array } } Now, this does violate some rules that I have read, such as "avoid new in the constructor," but to my eyes this does not seem untestable. These are properties of the object, not some black box data generator reading from an external source. Unit tests would progressively build up to any test of Widget-specific functionality, so I could be confident that the underlying FormFields were working correctly during the Widget test. In theory I could provide the Model with a FieldFactory() which could supply custom field objects, but I don't believe I would gain anything from this approach. Is this a poor assumption?

  • Ubuntu 11.10 and Mobility radeon HD 4570, 512MB can't find working drivers

    - by Slavak
    i'm pretty new to Linux and my new problem is ATI drivers. When i installed Ubuntu then i had black screen issue with the blinking in left upper corner, fixed it with F6 and set the "nolapic" mode, can boot only with "nolapic". Now the problem is the drivers. The suggested drivers, from the "Additional drivers" are not working. Always freeze at the login screen, the divers are: ATI/AMD proprietary FGLRX graphics driver Tried this method: http://drivers.downloadatoz.com/tutorial/28786,how-to-fix-amd-catalyst-11-10-not-working-on-ubuntu-11-10-issues.html? but this method break it down really hard, not ever that helped anymore: sudo /usr/share/ati/fglrx-uninstall.sh # (if it exists); sudo apt-get remove --purge fglrx*; sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon ; sudo apt-get install xserver-xorg-video-ati; sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core; sudo dpkg-reconfigure xserver-xorg Now i'm here with a fresh install and i cant find anything that works, can someone help me please! I like Ubuntu, but i need to get rid of the lagg, or its Windows 7 only for me then :( Thanks for reading!

  • Making LISPs manageable

    - by Andrea
    I am trying to learn Clojure, which seems a good candidate for a successful LISP. I have no problem with the concepts, but now I would like to start actually doing something. Here it comes my problem. As I mainly do web stuff, I have been looking into existing frameworks, database libraries, templating libraries and so on. Often these libraries are heavily based on macros. Now, I like very much the possibility of writing macros to get a simpler syntax than it would be possible otherwise. But it definitely adds another layer of complexity. Let me take an example of a migration in Lobos from a blog post: (defmigration add-posts-table (up [] (create clogdb (table :posts (integer :id :primary-key ) (varchar :title 250) (text :content ) (boolean :status (default false)) (timestamp :created (default (now))) (timestamp :published ) (integer :author [:refer :authors :id] :not-null)))) (down [] (drop (table :posts )))) It is very readable indeed. But it is hard to recognize what the structure is. What does the function timestamp return? Or is it a macro? Having all this freedom of writing my own syntax means that I have to learn other people's syntax for every library I want to use. How can I learn to use these components effectively? Am I supposed to learn each small DSL as a black box?

  • 12.04, nvidia-settings makes one of my dual monitors grey and useless, disables network

    - by Kerrick
    I'm running Ubuntu 12.04 64-bit, Precise Pangolin, with a PNY GTS 250 1GB video card and a monitor plugged into each of the DVI ports. I'm using the proprietary drivers (post-release updates). If I set anything to do with Separate X Screens up in nvidia-settings (and write it to xorg.conf and reboot), my second monitor has a grey background, no menu bar, no ability to have a window on it, the second monitor doesn't get picked up in a screneshot, and if I move my mouse cursor to it it's an ugly black X. Plus, my network is unable to connect to anything. If I subsequently delete /etc/X11/xorg.conf and reboot, everything goes back to working, albeit with a single monitor activated. If I set anything to do with TwinView up in nvidia-settings, my second monitor starts working, but it isn't seen as a second monitor by Ubuntu, so I can't apply color calibration to it separately. Plus, my mouse gets "caught" between the monitors every time I try to move my cursor between the two. What gives? If it helps, this is the xorg.conf that nvidia-settings generates for Separate X Screens.

  • Does Google sometime prevent new white hat sites from ranking at all in some verticals?

    - by JVerstry
    Assuming someone wants to implement a new viagra or akai berry e-commerce website. There is a lot of competition and this site does not really bring something new, other than a new online counter to buy products at a nice price. Assuming this site does not use any black hat techniques and that it stays with Google quality guidelines, and assuming it has no (or few) backlinks (from non-authoritative websites). Assuming this website's pages are indexed properly in Webmaster Tool, and that no penalties are reported. No site improvements are suggested. Google crawls the site daily as reported in GWT. No robots.txt configuration issues. Does Google sometime decide to no rank this site for any user query (for weeks), because of lack of original content? The reason I am asking this is that I am trying to understand the possible cause of a similar situation I am observing with two sites. If so, what is the way out to start ranking for these site? If not, does it mean the cause is elsewhere for sure? Any confirmed info to get out of the maze is welcome.

Company OverviewHyundai Motor Company is one of the world’s fastest-growing car manufacturers, ranked as the fifth-largest in 2011. The company also operates the world’s largest integrated automobile manufacturing facility in Ulsan, Republic of Korea, which can produce 1.6 million units per year. The company strives to enhance its brand image and market recognition by continuously improving the quality and design of its cars. Business Challenges To maximize the company’s growth potential, Hyundai Motor Company undertook a project to improve business efficiency and reinforce data security by centralizing the company’s sales, financial, and car manufacturing documents into a single repository. Specifically, they wanted to: Introduce a smart work environment to improve staff productivity and efficiency, and take advantage of rapid company growth due to new, enhanced car designs Replace a legacy document system managed by individual staff to improve collaboration, the visibility of corporate documents, and sharing of work-related files between employees Improve the security and storage of documents containing corporate intellectual property, and prevent intellectual property loss when staff leaves the company Eliminate delays when downloading files from the central server to a PC Build a large, single document repository to more efficiently manage and share data between 30,000 staff at the company’s headquarters Establish a scalable system that can be extended to Hyundai offices around the world Solution DeployedAfter conducting a large-scale benchmark test, Hyundai Motor Company chose Oracle Exalogic, Oracle Exadata, Oracle WebLogic Sever, and Oracle WebCenter Content 11g, as they provided better performance, stability, storage, and scalability than their competitors. Business Results Lowered the overall time spent each day on all document-related work by approximately 85%—from 4.5 hours to around 42 minutes on an average day Saved more than US$1 million per year in printer, paper, and toner costs, and laid the foundation for a completely paperless environment Reduced staff’s time spent requesting and receiving documents about car sales or designs from supervisors by 50%, by storing and managing all documents across the corporation in a single repository Cut the time required to draft new-car manufacturing, sales, and design documents by 20%, by allowing employees to reference high-quality data, such as marketing strategy and product planning documents already in the system Enhanced staff productivity at company headquarters by 9% by reducing the document-related tasks of 30,000 administrative and research and development staff Ensured the system could scale to hold 3 petabytes of car sales, manufacturing, and design data by 2013 and be deployed at branches worldwide We chose Oracle Exalogic, Oracle Exadata, and Oracle WebCenter Content to support our new document-centralization system over their competitors as Oracle offers stable storage for petabytes of data and high processing speeds. We have cut the overall time spent each day on document-related work by around 85%, saved more than US$1 million in paper and printing costs, laid the foundation for a smart work environment, and supported our future growth in the competitive car industry.

  • Can't shutdown Ubuntu (Wubi Installation)

    - by zsgre3nd3s7
    I downloaded Ubuntu 12.04 using Wubi. The installation went correctly and everything was working fine until I tried to shutdown. I clicked shutdown and then Ubuntu started shutdown, but as soon as I saw the Ubuntu logo with blank dots under, it froze. I had to perform a hard shutdown. After booting my computer back and going into Ubuntu, I tried shutting it down again but this time it took me on a black page with lots and lots of log writing on the screen and after a little while, it stopped writing stuff. I was able to input characters using the keyboard and everything, but it never shutdown. I had to perform a hard shutdown again. Now it always gives me a Ubuntu logo and freezes. What should I do? I know hard shutdowns are bad and want to avoid them. Is there anyway to make shutdowns work? I tried a reboot and it also froze on the Ubuntu logo. Sony VAIO Model E SVE17115FDB Laptop. Graphic card - AMD RADEON HD 7650M (and it installed correctly in Ubuntu). BIOS - H2O Bios. Processor - Intel i7-3612QM. Edit: I only installed the AMD/ATI proprietary drivers FGLRX, not the AMD/ATI post release drivers because they keep showing an error message. Here is jockey.log. Edit 2: Here is the log that i mentioned before that appeared on my screen, it appeared after i tried reinstalling my AMD driver but failed so i reinstalled the other one. Sorry for the quality i took those pictures with my phone.

  • Ubuntu 12.04 nomodeset fixes boot problem but causes screen resolution to get stuck

    - by Thunder
    I've been searching the askubuntu forum for the past 3 days trying to figure out what's going on with my system and I have tried a lot of things but to no avail. So, I will explain my situation and tell you what I have tried and I hope someone can help me :) I have an: HP Workstation xw4100 Pentium(R) 4 3.00 GHz 1.5 GB RAM NVIDIA Quadro4 380 XGL graphics card It came with Windows XP and I set it up (with WUBI) to dual boot with Ubuntu 12.04 After installation I had the problem that so many people had with it booting to a black screen (mine was actually booting to the terminal basic shell) that is fixed by adding nomodeset into the grub. When I do that, MY screen resolution becomes stuck in 1280x768 (as opposed to 1366x768 before adding nomodeset) (and also, when running XP the best resolution is 1280x720) When I go to "additional drivers" it doesn't show any proprietary drivers, so I manually downloaded them using this command: sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current but after rebooting, that made the graphics even worse (now stuck as 800x600) SO I tried to configure the drivers with sudo nvidia-xconfig but that simply created an empty xorg.config file. I found one place where a guy gave information to manually input into the xorg.config file but that had no effect at all. Lastly I tried to install previous versions of the NVIDIA drivers, but they wouldn't even fully install. So now I have just re-installed Ubuntu 12.04 and I either need to find a better solution to the first problem (nomodeset) or get the nouveau driver to correctly configure to work with my nvidia graphics. Thanks for your help ahead of time!

  • Blank pale blue screen with Live USB Kubuntu on AMD Sempron 2800+ processor

    - by WGCman
    I am trying to install Kubuntu onto a USB stick to use on my Acer Aspire 1362 laptop with an AMD Sempron 2800+ chip. Using Windows XP, I downloaded and saved to the laptop's hard drive: kubuntu-2.04.1-desktop-i386.iso from the GetKubuntu website and LinuxLive USB Creator 2.8.16.exe from the Linux live website I then installed the latter and ran it, installing the kubuntu onto the Memory stick. Leaving the Bios setup unchanged, the USB stick is ignored and Windows boots. If I change the Bios boot order so that the memory stick takes precedence, I see a dark blue screen announcing Kubukntu 12.04, and on selecting either “live Mode” or “Persistent mode”, messages flash by quickly, some of which appear to be error messages, including “trying to unpack rootfs image as initramfs”, “cannot allocate resource for mainboard”, “no plug and play device found”. Eventually I see a pale blue screen with four moving dots announcing Kubukntu 12.04, similar to the login screen of my Kubuntu desktop, but no invitation to log in or indeed any dialog. After several minutes, this changes to a black screen with more messages including “no caching mode present”, “ADDRCONF(NETDEV_UP): wlan0: link is not ready”, then degrades to a blank pale blue screen which can only be moved by switching the computer off. Finding no way to log the error messages passing by, I managed to photograph most of them, but know no way to attach the photo to this forum. As suggested by User 68186 (to whom thanks!), I have edited my original post to reflect the recent progress, so the following two comments are now superseded.
