  • How can I ensure my Samsung Series 7 is actually using the Radeon switchable graphics?

    - by patricksweeney
    I have a Samsung Series 7 with the Radeon 6750M switchable graphics. The ATI software lets you force programs to use the dedicated card. However, I'm not convinced it is actually ever using it, as the frame rates on some non-taxing games (Portal, TF2) are merely OK. To make matters worse, it looks like the ATI Catalyst Control has vanished from my laptop. To make it even worse, you can't download the driver and ATI CCC from ATI's site, you need to download it from Samsung, and the ZIP they provide is corrupted. How can I ensure my Samsung Series 7 is actually using the Radeon switchable graphics?

  • Taking web sites offline for demonstration on Galaxy Tablet

    This article is the Android sequel to the initial article about how to prepare an offline version of your web site for the purpose of demonstration or for exhibitions: Taking web sites offline for demonstration. If you didn't read the original article, please take some minutes (5 to 10 maximum) to gain a better understanding on the following. Thanks. I'm going to describe my steps using a Samsung Galaxy Tab 10.1 running on Ice Cream Sandwich (ICS - version 4.0.4) but I would assume that any other Android-based device will show more or less the same results.

  • Low end dedicated GPU vs. integrated Intel graphics (for light CAD work)

    - by PaulJ
    I have been asked to spec a PC for an interior design business. They are going to do some AutoCAD work (but they won't be using massive datasets or anything), and also use Kitchen Draw, a program that has 3D visualization features and says, in its requirements, that "a recent NVidia or ATI card might be enough". Since they are very limited budget-wise, I had originally picked a GeForce GT 610 card, but this card is so low end that I'm left wondering whether it will be an improvement at all over the dedicated Intel HD2500 graphics chip that comes with the CPU (I will be using an Ivy-Bridge Intel i5). Most of the information I see around is for gaming, which isn't really relevant in my case. Basically, for the use case I've described (light 3D work), can one get away with a current Intel HD graphics chipset? And will a low end GPU like the GT 610 provide a noticeable improvement?

  • Display with intel integrated graphics, bitcoin mine with Radeon 6950

    - by karategeek6
    I'm on Ubuntu Linux 11.04 64 bit. I have an intel i5 with integrated graphics and a Radeon 6950, with one monitor. I would like to run my graphics on the integrated card, and run bitcoin mining on the 6950. I have bitcoin mining working when I use the 6950 for both display and mining. Every time I try and and use the integrated graphics instead, OpenCL doesn't recognize my 6950. Using aticonfig --initial when using the integrated graphics for display breaks things. So I used the xorg.conf it created as a basis and tried to manually edit it. I really don't know what I'm doing, though. My last attempt is given below. The graphics ran off the integrated card, but the 6950 wasn't recognized. Any help would be greatly appreciated! xorg.conf: #Section "ServerLayout" # Identifier "Intel Layout" # Screen "Default Screen" # Identifier "aticonfig Layout" # Screen "aticonfig-Screen[0]-0" # Screen 0 "aticonfig-Screen[0]-0" 0 0 #EndSection Section "Module" Load "glx" EndSection # Intel Section "Device" Identifier "Intel Integrated Graphics" Driver "intel" BusID "PCI:0:2:0" EndSection Section "Monitor" Identifier "Default Monitor" Option "VendorName" "Monitor Vendor" Option "ModelName" "Monitor Name" Option "DPMS" "true" EndSection Section "Screen" Identifier "Default Screen" Device "Intel Integrated Graphics" Monitor "Default Monitor" DefaultDepth 24 EndSection # ATI Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:1:0:0" EndSection Section "Monitor" Identifier "aticonfig-Monitor[0]-0" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Screen" Identifier "aticonfig-Screen[0]-0" Device "aticonfig-Device[0]-0" Monitor "aticonfig-Monitor[0]-0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection

  • dual-boot (win-xp/ubu12.04) graphics card for ubu-desktop/win-xp-games

    - by iole1
    for work I need to get a a new and cheap graphics card for a dual boot machine: windows xp/ubuntu 12.04 LTS. The only requirements I have are: it should work 'flawlessly' in ubuntu (proprietary drivers are ok) it should handle Guild Wars 2 & League of Legends in windows xp (this is really the top priority as we need to be able to play at work :) - yes I have a cool job) I know nothing about graphics cards (and it seems to be a jungle out there). From other questions here and some webstigation I think I'd like to go for a Nvidia card, I've been trying to figure out what models fit the system req's but it seems they use different kind of model numbers so I don't get any wiser. tl;dr: will http://www.geforce.co.uk/hardware/desktop-gpus/geforce-gt-620-oem/specifications run Guild Wars 2 http://gamesystemrequirements.com/games.php?id=938 Or what is the worst card from nVidia that will run GW2 smoothly and work well in Ubuntu 12.04 Thanks!

  • XNA - Drawing 2D Primitives (Boxes) and Understanding Matrices in Computer Graphics

    - by MintyAnt
    I have two issues which I wish to solve by creating 2D primitives in XNA. In my game, I wish to have a "debug mode" which will draw a red box around all hitboxes in the game (Red outline, transparent inside). This would allow us to see where the hitboxes are being drawn AND still have the sprite graphics being drawn. I wish to further understand how matrices work within computer graphics. I have a basic theoretical grasp of how they work, but I really just want to apply some of my knowledge or find a good tutorial on it. To do this, I wish to draw my own 2D primitives (With Vertex3's) and apply different transormation matrices to them. I was trying to find a tutorial on drawing primitives using Direct3D, but most tutorials are only for c++, and just tell me to use XNA's Spritebatch. I wish to have more control over my program than just with Spritebatch. Any Help on using Direct3D or any other suggestions would greatly be appreciated. Thank you.

  • How to prevent creation of monitors.xml?

    - by user222723
    I'm using Ubuntu on a tablet and have a problem with the screen rotation, which I can fix by removing ~/.config/monitors.xml, but sadly every time I rotate the screen a new monitors.xml is created. Is there any way to prevent this? I already tried to create an empty file with the same name as root but it was still overwritten after rotating the screen. Edit: I think I finally found the reason for the problem. Everytime the orientation is changed the new orientation is saved in monitors.xml while the original monitors.xml is saved as monitors.xml.backup. By playing around with chattr I found out that this causes Ubuntu to try to restore monitors.xml out of monitors.xml.backup after every login. So if I turn the screen to the left and then back to normal monitors.xml says "orientation=normal" and monitors.xml.backup says "orientation=left". After the login Ubuntu overwrites monitors.xml with the backup and uses its configuration and turns the screen to the left.

  • Qt Graphics et performances - le coût des commodités, un article de Gunnar traduit par Guillaume Belz

    Le 11 décembre 2009, la documentation de QPainter subissait un énorme ajout concernant l'optimisation de son utilisation. En effet, le bon usage de cet outil n'était pas accessible à tous, il n'était pas présenté dans la documentation. Ceci ne fut qu'un prétexte à une série d'articles sur l'optimisation de QPainter et de Qt Graphics en général. Voici donc le premier article de cette série, les autres sont en préparation : Qt Graphics et performances : ce qui est critique et ce qui ne l'est pas Pensez-vous que cet ajout à la documentation de QPainter sera utile ? Trouvez-vous les performances de vos applications trop faibles ?...

  • How do you turn off touch on a Wacom Bamboo CTH-470?

    - by Foxx
    I bought my girlfriend a Wacom Bamboo CTH-470 recently and it is running well after installing wacom-dkms. I have now run into a wall that I don't know how to get around. The touch on the tablet will not turn off. I am running Ubuntu 12.04 Beta 2. I have tried turning the touch off from the wacom settings in the settings menu. The pen and touch both work perfectly fine, it is just that the touch drives her insane when trying to draw in myPaint.

  • Dual monitor setup with Intel graphics and Nvidia Geforce GT 425M on 12.04

    - by fo_x86
    I have a Dell XPS L401x and just installed 12.04. I have a mini-display and an HDMI output, and I could hook up two Dell UltraSharp monitors to each port on Windows 7, and get a triple monitor setup. Doing a bit of research, it seems like the mini-display is wired to the integrated graphics card whereas HDMI is hooked up to Nvidia graphics card. I've also installed Bumblebee as it seemed like that was the proper way of installing Nvidia drivers on Ubuntu. At the moment none of my monitors is being recognized by Ubuntu. Is it even possible to have a triple monitor (laptop display + 2 external) setup? Has anyone successfully done this?

  • Energy saving with two batteries (Gigabyte S1080 and similar)

    - by user37155
    my today question is: how do I manage a tablet (Gigabyte 1080) with an additional battery in Ubuntu ? The control bar shows two separate batteries but starts to suck all the energy from the secundary battery, not leaving any power in it and ruining it (if I don't remove it earlier), and then starts with the primary battery. Here you find a description of the secundary battery: http://www.gigabyte.com/products/product-page.aspx?pid=3837#kf Do you have some solutions for a more confortable use of te device, with windows-like drivers maybe ? Is there a graphical tool to manage two batteries in Linux, in order not to ruin them, and possibly to save energy with them ? Many thanks and greetings, Francesco

  • What are some tablets that can run Ubuntu?

    - by tacozmeister
    I can't believe I'm actually asking this, but what are some good, cheap tablets that can run Ubuntu? I'm considering getting a tablet, but I don't really want an expensive one like an iPad. And I love Ubuntu. So what tablets are out there that are cheap, but can also run Ubuntu 12.04 without much lag if it's installed after purchase? Personal anecdotes would be appreciated! Note: I'm not asking you to help me shop, just to formulate a list of tablets (+personal preference) that can use Ubuntu.

  • Can emsripten compile down to Canvas-based Js instead of WebGL?

    - by Sebastian Scholle
    I understand that emscripten compiles down LLVM to JS and it converts OpenGL Calls to WebGL. Thats a fairly simple translation. Is there a way to tell emscripten to use some other graphics Library ( for example Pixi JS ) for its rendering code translations? Is the compiled JS code easy to update or would it be better to merge in your own Graphics API that handles WebGL/Canvas calls. IE: can we use a C++ Graphics Wrapper Library that when compiles to JS, will simply plug into our own JS Graphics Wrapper Library? Im assuming YES, but has anyone tried this? And if So, what would be your technique, as my C++ skills are basic.

  • How do I disable a Nvidia 9600GT on MacBookPro 5.1?

    - by Gjan
    i finally put up a Dual Boot with Ubuntu and Lion on my old MacBookPro 5.1 As reported in many cases the discrete graphics card is turned on all the time consuming a lot of power and thus heating up the laptop. Since the discrete graphics card does not support the nvidia optimus technology, the corresponding packge nvidia-prime does not help in this case. Therefore my question is, how to manually disable the discrete graphics card Nvdidia 9600GT ? Preferably a 'switch-on-the-run' version, but a 'set-on-boot' would be totally fine!
