• Macbook Pro 2011 compatibility

  - by ldx

  Hi there, I'm planning to a buy a new 13" Macbook Pro, the one that was just released this week with the Thunderbolt port. The question is, has anyone given it a shot with Ubuntu (10.10 or 11.04 alpha)? I'd be especially interested whether temperature sensors/fan control, external displays via the displayport and 3D acceleration (for Compiz or some simple 3D games) via the integrated HD3000 GPU work without flaws. Thanks!

• Avoid double compression of resources

  - by user1095108

  I am using .pngs for my textures and am using a virtual file system in a .zip file for my game project. This means my textures are compressed and decompressed twice. What are the solutions to this double compression problem? One solution I've heard about is to use .tgas for textures, but it seems ages ago, since I've heard that. Another solution is to implement decompression on the GPU and, since that is fast, forget about the overhead.

• What is the purpose of bitdepth for the several components of the framebuffer in glfwWindowHint function of GLFW3?

  - by Rui d'Orey

  I would like to know what are the following "framebuffer related hints" of GLFW3 function glfwWindowHint : GLFW_RED_BITS GLFW_GREEN_BITS GLFW_BLUE_BITS GLFW_ALPHA_BITS GLFW_DEPTH_BITS GLFW_STENCIL_BITS What is the purpose of this? Usually their default values are enough? Where are those bits stored? In a buffer in the GPU? What do they affect? And by that I mean in what way Thank you in advance!

  - by musicalfish8

  I have a problem in which I boot my computer and everything works normally, I see a purple screen with various partitions to select such as my Windows 7 and Ubuntu partitions. When I select the Ubuntu one, my computer boots to an orangish screen and plays what sounds like a drum sound once. Then nothing happens and I have to reboot my computer because the computer is stuck at this orange screen. EDIT: My hardware is: Asus M5A97 motherboard AMD Phenom II 630 processor MSI r6670 MD1GD5 GPU TrendNet TEW-641PC Wireless Card

• Can't boot Ubuntu 12.10 graphics problem

  - by Frantumn

  I can't boot since installing Ubuntu 12.10 When I try to run Ubuntu My computer never gets to the Ubuntu screen with the loading dots. I tried to run in recovery mode with safe graphics (failsafex) When I do this a message pops up saying "the system is running in low graphics mode", If I click okay I am asked what would I like to do and am given four options. I tried running low graphics for one session and then a message appears with a progress bar and says standby one minute while the display restarts. The progress bar never moves and if I click okay the whole process just restarts. I Don't know what to do from here I can't get into the OS. I'm not sure whether the problem is related to compatibility with my laptop monitor or my graphic card nvidia360m I had to install using a safe graphics mode. To learn about how I installed see this link. This link also has information on my computer hardware. Can't install Ubuntu since 10.10 ----UPDATE--- I was able to get into a desktop environment By installing Nvidia-current however it is messy. I have a screen and I am able to see my desktop however there is no unity bar and none of the keyboard controls work. I can right click and create a folder on the desktop and then I can see inside that folder in a traditional browser window. There is still no top menu or unity bar. When I boot normally I don't get into the desktop environment and I get this message in tty 'GPU lockup switching to software FBCON' Okay, I've played around with tips the pages from comments. I've been able to consistantly get into a safemode desktop environment using the xorg & nouveau drivers. I've tried switching between the 5 different options in the Additional Drivers tab in Software Sources. The nVidia (proprietary, tested) driver gets beyond the GPU lockup on a normal boot and actually gets into a Desktop. The issue is then that there is no Unity bar, or top screen menu bar and the resolution is very low. I've tried switching to the (prop, tested) driver and then reinstalling Unity and Ubuntu-Desktop but that didn't work either.

• Library For Opengl 1.4?

  - by Robinson Joaquin

  My netbook only supports openGL version 1.4, my GPU is intel gma 3150, so for you what is the best library/tools to use or somewhat great move to make/advice, there are no wrong answers, (I am trying to create a game) PS: I already check the net for resources but, opengl (redbook) 4th edition is scarce (and redbook for v1.1 is already deprecated and is very OLD than what I'm looking for), besides I don't have money to buy a new laptop or a opengl book from online shop because international delivery is very expensive, I'm from outside US.

• 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).

• Enabling a multi display desktop completely broke Gnome Shell. Help?

  - by Chintan Parikh

  I've been trying to get my dual desktops working on Ubuntu for a while. I previously had them as one large desktop, but that was incredibly slow for some reason. I tried to switch them to multi display desktop on the AMD Catalyst Control Center. Here's what I get after restarting and logging in: http://i.imgur.com/SEjgU.png I'm running an AMD Quad Core A6, AMD Radeon 6540G2 GPU, 16GB Ram. Ubuntu 12.04 Any ideas?

• How to check battery usage of an iPhone/Android app?

  - by Gajoo

  I think the title says Enough. For example Unity can generate you a report how much CPU/GPU power it's using or how fast it's going to drain device battery, but what about the applications developed using Cocos2d or the ones you develop directly using OpenGL? How should you profile them? In general what should you profile? or Should I simply run the application and wait for it's battery to run out?

• How effects found in "Autodesk Fluid FX" are implemented using OpenGL ES?

  - by afds

  How this kind of effects are technically implemented using OpenGL ES? Are they performing simulation on GPU (using Shaders) or CPU while using some smart vertex positioning and texturing? Why it appears so fast (in terms of performance)? You might check the video of that app here: http://www.youtube.com/watch?v=F4KOk6QP6kQ edit Here is the presentation for the app: http://www.futuregameon.com/FGO2010_JosStam.pdf

• Will Intel HD 3000 serve my needs, or should I opt for AMD Radeon 6650G?

  - by Matt

  I am going to be purchasing a new laptop soon, and have several models in mind at the moment. The really difficult part has been trying to determine whether or not Intel HD 3000 integrated graphics will meet my needs/desires (Unity 3D, use of Netflix via a virtualbox installation of Windows 7, and possibly Compiz effects) or if I should opt for one of the models with a dedicated GPU. So basically, what are the capabilities of the Intel HD 3000, and are they up to snuff?

• Dual NVidia graphics cards in Ubuntu / xorg.conf mania

  - by John Zwinck

  I have two NVidia graphics cards: Quadro NVS 295 (PCI Express, dual DisplayPort outputs) GeForce FX 5200 (PCI, DVI and VGA outputs) I have three identical monitors, two on DisplayPort and one on DVI. I'm on Ubuntu Hardy (and cannot currently dist-upgrade for separate reasons). I use the "nvidia" driver. What's new is the GeForce card and the third monitor. I currently have the dual DisplayPort monitors working fine. Here are the display-related parts of my xorg.conf: Section "ServerLayout" Identifier "Default Layout" Screen "PCI-Express Screen" 0 0 # adding this makes X fail to start: Screen "PCI Screen" 0 Inputdevice "Generic Keyboard" Inputdevice "Configured Mouse" EndSection Section "Module" Load "glx" # not sure why/if this is needed EndSection Section "Monitor" Identifier "DELL 2408WFP" Option "DPMS" EndSection Section "Device" Identifier "NVIDIA Quadro NVS 295" Driver "nvidia" Option "RenderAccel" "true" Screen 0 BusID "PCI:2:0:0" EndSection Section "Device" Identifier "NVIDIA GeForce FX 5200" Driver "nvidia" Option "RenderAccel" "true" Screen 1 BusID "PCI:6:4:0" EndSection Section "Screen" Identifier "PCI-Express Screen" Device "NVIDIA Quadro NVS 295" Monitor "DELL 2408WFP" Defaultdepth 24 Option "TwinView" "True" Option "UseEdidFreqs" "True" Option "MetaModes" "1920x1200 +0+1200, 1920x1200 +0+0" EndSection Section "Screen" Identifier "PCI Screen" Device "NVIDIA GeForce FX 5200" Monitor "DELL 2408WFP" Defaultdepth 24 Option "TwinView" "True" Option "UseEdidFreqs" "True" Option "MetaModes" "1920x1200 +0+0" EndSection I use nvidia-settings to configure my monitors, and it does not show the second GPU. lspci, though, shows: 02:00.0 VGA compatible controller: nVidia Corporation Unknown device 06fd 06:04.0 VGA compatible controller: nVidia Corporation NV34 [GeForce FX 5200] Which is where I got the BusID settings for the two devices (when I just had one device, I didn't have any BusID listed...and adding the BusID hasn't broken anything). What am I missing? How can I make nvidia-settings show my second GPU so I can then configure its monitor?

• Video card not detected on Lenovo T410 in Linux

  - by wich

  I have a T410 with an nVidia NVS 3100M, this is not a hybrid system, there is no Optimus. (No option in the BIOS for Optimus, lspci in linux as well as the Windows device manager only show the nVidia) Using lspci I see the GPU as a present device, however, I can not, for the life of me, get any video driver to work that will let me start an X session, every time X craps out with the error (EE) No devices detected. I have tried the nVidia binary blob, (with nvidia-config, made sure no nvidia support in the kernel), I have tried nouveau, I have tried nv, I have even tried generic vesa, nothing will work. When I compare the dmesg that I get when loading the nvidia kernel module, I see that it is missing some lines compared with another system that also has an nvidia card, specifically the line mentioning the GPU name (3100M) is not there. I have checked every option in the BIOS, there is nothing to control except for the BIOS video output port, which is set to the LCD panel. I have no idea anymore what the problem may be, or even how I can diagnose this problem further. Any help will be appreciated.

• Getting the most out of a Mac mini as a media center

  - by celebritarian

  Hello! I own an old Mac mini from 2006 (maybe early 2007). It's got an Intel Core Solo 32-bits CPU and 512 MB RAM. 160 GB HDD. The GPU is an integrated chip… Currently, my Mini is sitting under my LCD TV (720p). It's plugged in via a DVI to HDMI cable. It's currently running Leopard. And unfortunately, Snow Leopard can't be installed on a device with less than 1 GB of RAM… So, my Mac mini isn't exactly powerful. Also, it's slow and Mac OS X is not a pleasant experience on my Mini right now. It feels slow and heavy. I want to use my Mac mini as a media center/player. I want to be able to play video files in 720p (H.264, Matroska/MOV files). So basically, playing high-def videos is all I want to do with my Mini. What OS should I install? Stick to OS X? Optimize for video playback? Or should I install another OS — like Win XP, Ubuntu or any other Linux dist? Then, will my Mini be able to play 720p videos smoothly, even though the CPU and GPU aren't that powerful and with the limit of 512 MB of RAM? Appreciate all help. Thanks in advance!

• Enable CPU fan always on

  - by Gundars Meness

  I am using 3 years old overheating laptop and I want my CPU fan to be spinning 24/7 regardless of the consequences. How to make it spin? The problem is that CPU & GPU heats up to 68°C (154 F) right after boot and never goes down, because CPU fan is not spinning full throttle. It starts spinning faster when temperature goes over 70°C and stops when it reaches seventy again. When doing heavy work on databases, it gets from 70 to 90 in no-time and automatically powers off. Bios does not contain any "fan spin 100%" options, just "spin slowly all the time" and "auto" which is more useless than the first one since my fan doesn't have pwm wire. Currently I'm solving this with cooling stand (3x5V), but it isn't much of a help. I would rather use the CPU fan since it is the only fan directly responsible for cooling down CPU/GPU. But how to make it spin 100% all the time? Should I attach it's red power wire to motherboard to get constant 5V (is there such option?), or is there an option to control it via software? Laptop: Samsung R528 2.3 GHz Intel i3 with Nvidia GeForce 310M Bios: Phoenix 03KT.M003.20100622.KSJ (and that is latest update) OS: Ubuntu 12.04.2 LTS with 3.2.0.51 kernel CPU fan: Image/Description Has 5V 0,4A and only 3 pins, no pwm. P.S. Yes, I did clean everything with alcohol, freed the air vents, changed thermal paste etc; that reduced temperature by 4 degrees.

• Constant crashes in windows 7 64bit when playing games

  - by yx

  I've tried everything I can possibly think of in trying to fix this problem and I'm totally out of ideas, so any help would be appreciated: The problem: whenever I fire up a game, it works for a short while with no problems and then it would crash. Either its a hard crash, forcing me to reboot, or windows would report that the display driver has stopped working and recovered. Here is a list of things I've already tried: Drivers - tried the latest drivers (catalyst 9.12) as well as the stock drivers that came with the video card. Also have the latest BIOS/chipset Memtest - Ran Memtest86+ overnight, had no problems, the windows diagnostic tool also does not find any problems. Overheating - Video card/cpu temperatures are well below peak (42 and 31 Celsius receptively) PSU Voltage - CPUID shows that the voltage levels are all above what they should be. The PSU itself is only roughly 16 months old and is a good model. HDD - No errors when checked GPU - Brand new (replaced previous card since I thought it was the problem, apparently not) Overclocking - Everything is at stock levels, memory voltage is set to manufacturer's standard Specs: Motherboard: ASUS P5Q Pro CPU: Core 2 Duo E8400 3.0 ghz OS: Windows 7 home premium 64 bit Memory: Mushkin Enhanced 4GB DDR2 GPU: Sapphire HD 5850 1GB PSU: SeaSonic M12 600W ATX12V DirectX: DX11 Event Viewer after a crash always has these logged: A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 1 The details view of this entry contains further information. A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 0 The details view of this entry contains further information. A previous card that I had (4850x2) also had these errors, so I changed video cards, but the same thing is happening.
