• WinXp display driver incorrect to boot iso ubuntu 12.04

  - by user285829

  I have Windows Xp on a HP Pavilion w/AMD Athlon 64 processor 3300+. I have downloaded Ubuntu 12.04 iso desktop. When trying to run Ubuntu, I get a line that says "sis 630 buss not detected. It continues and makes a blue screen, then says low graphics mode only and has a white screen. The HP has display adaptor sis 760, driver= 6.14.10.3671, 4/20/2005. I'm not familiar with ubuntu because I've never got it started as yet. Can the Ubuntu install process be changed to accept my sis 760 driver? I'm trying to make a Live CD(dvd) to run Ubuntu.

• how to deal with parallel programming

  - by nkint

  Hi. I know that parallel programming is a big resource in computer graphics, with moder machines, and mayebe a computing model that will be grow up in the near future (is this trend true?). I want to know what is the best way to deal with it. there is some practical general purpose usefulness in studying processor n-dimensional mesh, or bitonic sort in p-ram machines or it's only theory for domain specific hardware used in real particular signal elaborations of scientific simulations? Is this the best way to acquire the know how for how to become acquainted with cuda or opencl? (i'm interested in computer graphics applications) and why functional programming is so important to understand parallel computing? ps: as someone has advice me i have forked this discussion from http://stackoverflow.com/questions/4908677/how-to-deal-with-parallel-programming

• Best database setup for one click games

  - by ewizard

  I am building a one click game website/mobile app, and I am debating between using MySQL and MongoDB for the backend. The way I have been exploring it is with a NodeJS/Express/Angular/Passport/MongoDB stack - I have also implemented Socket.io. I have gotten to the point where I am sending data from the flash game to the server (NodeJS). The only data that needs to be sent is basic user information, the players score at the end of each game, and some x,y positions for each players game (for anti-cheating). It seems like MySQL would work fine, but as I am already using MongoDB - are there any major drawbacks to continuing to work with MongoDB on this project?

• How do I find a proprietary driver for the Intel graphics card I have?

  - by user69798

  I have an Intel corporation core processor integrated graphics controller (rev 18), and I am trying to get a proprietary driver for my graphics card so I can play Amnesia from the Humble Bundle. I am a female that can easily follow directions but doesn't know much about Linux yet. If you give me precise directions, I will follow them so you can help me fix the problem. I would really appreciate it! My laptop is a Dell n7010. Additional info: I believe that it is the graphics card that is causing Amnesia to crash, but I am unsure. I have tried running it on the lowest possible settings, and it crashes after the first loading screen. :( Also, I installed via the Ubuntu Software Center after purchasing the Humble Bundle. I have not tried the other games yet.

• Ubuntu 12.04 very slow on samsung netbook

  - by vallllll

  I have a samsung netbook n150 1Gb Ram (Intel graphic card), 1,66GHz Intel Atom processor. It was working great with the ubuntu 10.04 netbook edition, really fast boot very eficient but I have updated to 12.04 (the netbook edition doesn't exist anymore) and now the system is so slow: slow boot, sometimes it doesn't even boot properly, strange screen light on and off behaviour, when you click on an icon takes for ever to open the app even the terminal it takes like more than 10s! It seems that this new distro was made for a far more powerful systems than this netbook. I am considering to revert back to 10.04 or choose another linux distro but is there anythhing i can do to fix these problems? Any body else had similar problems. Thanks in advance

• Now that Device Central is dead, how can I test my Flash Lite applications?

  - by Kirby

  I'm trying to use Flash Lite to make a simple game for my girlfriend, who only has a Nokia 5530, but I just realized in CS6 Adobe killed Device Central, so there's no way for me to test it without the device (and it's supposed to be a surprise). Is there any other way for me to test it? I know I can just export the movie and use Flash Player, but Device Central allowed me to test drag and drop and memory/processor usage for example... tl;dr, is there an alternative to Device Central for testing Flash Lite in older devices?

• installing ubuntu 13.04 along side window 7 64 bit

  - by Shikhar Subedi

  I have a 64 bit computer with windows OS. Here are my specifications: core i3 processor 4 gb ram nvdia ge210 hard disk with 680 gb memory In my windows installation I have C: drive with 104 gb, D: drive with 246gb and E: drive with 246gb memory. My dvd rom is in f: drive. I want to install ubuntu 13.04 64 bit along side windows 7. So i burned the ubuntu 64 bit iso image onto a dvd and restarted the computer. but in the choice for installations, there is no option to select installing ubuntu along side windows. There is an option to install ubuntu inside windows instead. There are other options as well. What should I do to get the option to install ubuntu along side windows. I think the problem is with the number of drives in windows. Please tell me how should I make a partition in windows 7 to install ubuntu. Thanks a lot..

• JMeter: how to asign a single distinct value from CSV Data Set Config to each thread in thread group?

  - by JohnnyM

  I have to make a load test for a relatively large number of users so I cant realy use User Parameters pre-processor to parametrize each thread with custom user data. I've read that I should use CSV Data Set Config instead. However I run into a problem with how JMeter interprets the input of this Config. Example: I have a thread group of 3 threads and Loop Count:10 with one HTTP request sampler with server www.example.com and path: \${user}. The csv file (bullet is a single line in file) for CSV Data Set Config to extract the user parameter: 1 2 3 4 5 Expected output is that for thread 1-x the path of the request should be: \x. So the output file should consist of 10 samples per thread namely: for thread 1-1 : 10 requests to www.example.com\1 for thread 1-2 : 10 requests to www.example.com\2 for thread 1-3 : 10 requests to www.example.com\3 but instead i get requests to each \1 - \5 and then to EOF. Does anyone know how to achieve the expected effect with CSV Data Set Config in jmeter 2.9?

• Will Ubuntu be releasing an update for Cedar Trail Processors?

  - by Alan

  There is a file available on the Intel web site with the file name "cdv-gfx-drivers-1.0.1_bee.tar.bz2" and a date of July 6, 2012. It can be found by searching the Intel Download Center for the filename or the string "Linux* PowerVR Graphics/Media Drivers". The download page links to the file, release notes and a link, Enabling hardware accelerated playback that takes one to a page containing links to two pdf documents titled "Enabling Hardware Accelerated Playback for Intel® AtomTM Processor N2000/D2000 Series", one for Ubuntu and one for Fedora. The instruction and release notes speak to working with kernel 3.1.0 and since I do not feel I have the skills, knowledge or training to do anything else but, follow the instructions to the "T", I am very reluctant to try anything on my freshly updated 3.2.0 kernel. I would much rather use a Ubuntu supported kernel that applies these drivers and doesn't break anything in the process. Is it a case where this is so new that Canonical has not yet included these drivers but, soon will do so?

• Is the Lenovo Ideapad Z570 fully compatible with 12.04?

  - by umpirsky

  I'm looking for some notebook that will run on Ubuntu perfectly. I like LENOVO IdeaPad Z570, but I'm not sure how it will perform on Ubuntu. I heard people are complaining about wireless problems. Here is full configuraion: Processor Intel Core i5 2430M 2.4GHz - 3.0GHz Chipset Intel HM65 Express Memory 4GB DDR3 1333MHz Graphics NVIDIA GeForce GT 520M 1GB HDD 750GB SATA II Wireless 802.11b/g/n, Bluetooth 2.1 Network adapter Ethernet LAN 10/100Mbps Ports VGA, HDMI, 3x USB 2.0, eSATA Does anyone have experience with this model? Any problems noted? I heard there is a test suite, how can I install it? Maybe I can boot live CD and try it myself before buying it. But, unfortunately, sometimes something works on live CD, but not when you install it. I guess critical components here are graphics and wireless. Any feedback would be appreciated.

• Error after installing Ubuntu 12.04 using Wubi

  - by KJ50

  After using Windows Ubuntu Installer from within Windows, I am prompted to restart, so I follow the directions. When I try to start Ubuntu after restarting, the desktop background appears, but then a loading bar with this title appears. Verifying the installation configuration... While this is loading, an error window pops up that says No root file system is defined Please correct this from the partitioning menu There is only an 'Ok' button available to click, and if I click that the same error window appears. I do not know how to get to the "partitioning menu" from this state, so the only option I have is to shut down my computer. What can I do so that Ubuntu finds a "root file system"? Can I diagnose this problem via Windows? Does anyone have any insight? FYI - I am using a new ultrabook with 6GB RAM, Intel i7 3rd gen processor, and no CD/DVD drive.

• juju: How do I list all the relation variables and debug them interactively?

  - by mfisch

  I'm writing a charm that requires a mysql database, I found from looking at other charms that this (below) is how I get the info about the database: user=`relation-get user` password=`relation-get password` mysqlhost=`relation-get private-address` But I just found that from reading the wordpress charm example, is there a way to show all the relation variables that I can use? Also, while debugging my db-relation-changed script, I wanted to ssh into my host and interactively run those commands, for example relation-get user, but it didn't work. I resorted to having to restart everything and use juju log to print them out. This wasted a lot of time. Is there a way to print out these relations, either from my dev box or from the instance running my charm? (Below is what happens when I tried to interactively run relation-get): ubuntu@mfisch-local-tracks-0:~$ relation-get user usage: relation-get [-h] [-o OUTPUT] [-s SOCKET] [--client-id CLIENT_ID] [--format FORMAT] [--log-file FILE] [--log-level CRITICAL|DEBUG|INFO|ERROR|WARNING] [-r RELATION ID] [settings_name] [unit_name] No JUJU_AGENT_SOCKET/-s option found

• How do I use Content.Load() with raw XML files?

  - by xnanewb

  I'm using the Content.Load() mechanism to load core game definitions from XML files. It works fine, though some definitions should be editable/moddable by the players. Since the content pipeline compiles everything into xnb files, that doesn't work for now. I've seen that the inbuild XNA Song content processor does create 2 files. 1 xnb file which contains meta data for the song and 1 wma file which contains the actual data. I've tried to rebuild that mechanism (so that the second file is the actual xml file), but for some reason I can't use the namespace which contains the IntermediateSerializer class to load the xml (obviously the namespace is only available in a content project?). How can I deploy raw, editable xml files and load them with Content.Load()?

• How to improve Unity Performance?

  - by Wolter Hellmund

  I installed ubuntu netbook edition on my netbook* expecting to get the best performance out of it, but apparently, that didn't turn out. Unity is a bit slow on it, and when I click on Files and folders it takes a while to load the respective interface and the bar at the top disappears and then loads in. Is this expected? Is there anything I can do to improve the performance? Is this problem specific to my netbook? *Netbook info: Acer - Aspire One 1.6 GHz Intel Atom Processor 1 GB RAM Memory Intel GMA 950 graphics card

• Game getting progressively laggier?

  - by Valentin Krummenacher

  I have a small game in HTML5 that uses socket.io to communicate with a node.js server. Now my problem is that, eversince I did my last update on it it seems to have something "chunk up" in the background making it laggier and laggier the longer it runs. In the update were a few temporary local variables being defined with var(you know, variables that are only used during one function and then not needed anymore) alongside with alot of other changes, and I am not even sure if this update or something else is causing this. Might the "var" have caused it? Or what other reasons might this strange complication have?

• Ubuntu swappiness

  - by Viswanath Kuchibhotla

  I have a laptop with 4 GB RAM and i3 processor. It runs very fast when I use windows, but it keeps slowing down on my Ubuntu when I use it continuously. I noticed that 500mb+ swap is getting used even if only 20% of RAM is only used, and I have a doubt that this is the reason for the slowness. I have already set the swappiness value to 10. Then how else can I change it? I spend most of my time in Ubuntu so this is very important for me.

• Need help with gimp 2.8 (cpu not used to full capacity) [closed]

  - by Birgir Freyr

  I know this isn't the right place to ask this question but maybe some one here can point me out to were I should place this question (or help me fix it :)). Since I updated Gimp to 2.8 (and let me start by saying how happy I am with the new gimp) I have notice that Gimp only uses 35% max of my CPU power. I have tried changing settings, assigning only one CPU to Gimp (both in gimp preference and in windblows task manager). No matter what settings I choose it only uses 35% of the cpu. If I assign just one Core to it then Gimp will use 100% of that core (which is about 35% of a three core processor I have. Any thoughts? I am using Windblows 7 64 bit, gimp 2.8.0, AMD a6-3500 cpu. I also use Ubuntu (am going to see if it works the same there). Any help would be great.

• dual display breaks unity

  - by dougleduck

  I find that most of the time, when I plug in my Dell 19" monitor with an HDMI lead, unity can't decide on the configuration; it will switch between different resolutions, and setups every 2-30 setusecond until I either ctrl-alt-backspace or unity crashes so I have to hard boot. Alternatively all the windows decorations and unity get killed. My setup is 11.10 64 bit,Dell Vostro 3550, AMD Radeon HD 6630M 1GB, Intel Core i5-2520M processor 2.50 GHz with integrated graphics card Currently I don't think the Radeon graphics card is working properly, but I'm not sure.

• PowerXpress error with Driver Catalyst. How can I fix it?

  - by J03Bukowski

  I have install Ubuntu 11.10 64bit on my Hp Dv6-3150el. My Notebook has two graphics cards: lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) 01:00.0 VGA compatible controller: ATI Technologies Inc Madison [AMD Radeon HD 5000M Series] I tried to install the proprietary graphics drivers ''fglrx'' available in "Additional Drivers", which does not give me 3D graphics acceleration (and I can't install those post-release). Then I can try to download and install from the website (I tried the version that Catalyst 11.8 11.12). The installation goes perfectly (I followed this guide and others), except that when I configure Xorg.conf file: sudo aticonfig --initial PowerXpress error: Cannot stat '/usr/lib64/fglrx': No such file or directory Failed to initialize libglx for discrete GPU

• video/audio output via HDMI Ubuntu 12.04

  - by lostNfound

  I've been out of the Ubuntu loop for quite a while now and have a completely new laptop now. Just installed Ubuntu 12.04 64-bit and would like to output my video and my audio via HDMI to my television. the following is the lspci | grep VGA for my computer. please tell me if there is any additional information needed and preferably how to obtain it and i will be more than happy to oblige. thank you in advance for your time and assistance in this matter. 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev a1) Edit: every time i restart my computer, after a short moment, i get an error message stating something along the lines "sorry, jockey needed to close unexpectedly." after researching, i discovered jockey is the name of the "additional drivers," which after initial installation, ubuntu informed me of proprietary drivers available. those are no longer available, and this error continues to occur.

• XNA: Retrieve texture file name during runtime

  - by townsean

  I'm trying to retrieve the names of the texture files (or their locations) on a mesh. I realize that the texture file name information is not preserved when the model is loaded. I've been doing tons of searching and some experimenting but I've been met with no luck. I've gathered that I need to extended the content pipeline and store the file location in somewhere like ModelMeshPart.Tag. My problem is, even when I'm trying to make my own custom processor, I still can't figure out where the texture file name is. :( Any thoughts? Thanks! UPDATE: Okay, so I found something kind of promising. NodeContent.Identity.SourceFilename, only that returns the location of my .X model. When I go down the node tree he is always null. Then there's the ContentItem.Name property. It seems to have names of my mesh, but not my actual texture file names. :(
