• Macbook Pro 8,2 Graphics switching - Ubuntu 12.04

  - by fgs

  I've been reading docs and various pages for a few hours now and can't seem to put all of the pieces together on this. Basically I am trying to get 12.04 installed on my MBP 8,2 with graphics card switching working in some way or another. My basic understanding is that I need to do an EFI boot install of ubuntu so that graphics card switching will work (due to the hardware design). From there I may be able to use one of the kernel modules for graphics switching: https://help.ubuntu.com/community/HybridGraphics That article isn't clear on whether I need to do an EFI install. I have also seen comments in posts here that say and EFI install works by default as long as you have refit installed. Overall, I'm quite lost as to the simplest way to proceed to get an install up and running with graphics switching. I don't mind using open source GFX drivers as long as the basics work. Any help towards a solution is greatly appreciated.

• Correct nvidia+intel graphics setup in 14.04

  - by Espressofa

  Just upgraded to 14.04 to try to fix some other issues. Now, something has gone wrong with my graphics. I have a Thinkpad T530 with Intel and Nvidia graphics cards. $ inxi -SGx System: Host: xyz Kernel: 3.13.0-24-generic x86_64 (64 bit, gcc: 4.8.2) Desktop: N/A Distro: Ubuntu 14.04 trusty Graphics: Card-1: Intel 3rd Gen Core processor Graphics Controller bus-ID: 00:02.0 Card-2: NVIDIA GF108M [NVS 5400M] bus-ID: 01:00.0 X.Org: 1.15.1 drivers: fbdev,vesa,intel,nouveau (unloaded: nvidia) Resolution: [email protected] GLX Renderer: N/A GLX Version: N/A Direct Rendering: N/A $ glxinfo name of display: :0 Xlib: extension "GLX" missing on display ":0".

• AMD graphics drivers

  - by user284659

  I have a new laptop with dedicated graphics card and I decided I will go with Ubuntu 14.04. All is just fine and I love it but the repos for graphics drivers from Canonical are just well... old .Is there any problem if I install my graphics drivers from AMD's official website and not from Software Updater? It's just that from there i get the latest and greatest.I read the realease notes and 14.04 is supported.

• Trying to install Proprietory Nvidia Graphics Drivers

  - by Peter Snow

  After reading and trying many different suggestions for some hours, I returned to this how-to: https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia The first problem I encounter is how to identify which of the listed drivers support my Nvidia GEForce 630M graphics card. Following the links doesn't really help, since it is not stated there either (except where support for a new driver was added later which is explicitly stated, but the original devices covered are not). However, even if I knew, if it doesn't appear in the 'Additional Drivers' dialogue (see below), how will I install it? Second Issue: The article goes on to say that available drivers for my hardware are usually listed in 'Additional Drivers'. In my case, they aren't. Unfortunately, it doesn't tell me how to correct that or work around it? I've checked the bios and there is no way offered there to disable the integrated graphics, only the Nvidia graphics. I've also tried each available option in this: $ sudo update-alternatives --config i386-linux-gnu_gl_conf My system is an Acer Aspire 4752G bought May 2012. I'm running Ubuntu 12.04LTS. uname -a : 3.2.0-38-generic-pae #61-Ubuntu SMP Tue Feb 19 12:39:51 UTC 2013 i686 i686 i386 GNU/Linux It's 64bit hardware but I installed 32bit OS for greater software compatibility. Running $ sudo tail -fn 500 /var/log/Xorg.0.log | grep '(EE)' returns" (WW) warning, (EE) error, (NI) not implemented, (??) unknown. [ 28.886] (EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found) The reason for wanting the proprietor y drivers is because my laptop comes with 3D accelerated graphics adaptor and so rather than confining myself to struggling with the on-board graphics, I would rather use it. I also want to experiment with using it for bitmining (which uses the GPU's for computing power).

• Graphics corrupt after upgrade from 11.10 to 12.04

  - by RiaanZA

  I'm stuck at the moment with an ubuntu that boots into an unusable white screen after upgrading from 11.10 to 12.04. I've tried booting into safe X mode but it just throws me back to the safe menu every time. Restore previous graphics driver, use default graphics configuration and set up new graphics configuration all don't work either. I've tried various methods of resetting the graphics from the command line, but none are working due to unmet dependencies. These cannot be fixed by doing the normal "apt-get -f install" because its saying there is a dpkg error in var/lib/dpkg/status (blank line relating to skype-wrapper). I haven't been able to find any other way to fix the dependencies yet. Can someone please give me some advice on what to do, I really don't want to go the re install route.

• Good resources for learning about graphics hardware

  - by Ken

  I'm looking for some good learning resources for graphics hardware (and associated low level software). Basically I want to learn more about what goes on underneath the opengl/direcx API layers in terms of how things are implemented. I familiar with what happens in principle during the various stages of the rendering pipeline (viewing, projection, clipping, rasterization etc). My goal is to be able to make better and more informed decisions about tradeoffs and potential optimisations when graphics/shader programming with respect to the following kinds of issues; batching view culling occlusions draw order avoiding state changes triangles vs pointsprites texture sampling etc Basically whatever the graphics programmer needs to know about modern graphics hardware in order to become more effective. I'm not really looking for specific optimisation techniques, rather I need more general knowledge so that I will naturally write more efficient code.

• Is my graphics card in use or not?

  - by Lindhe94

  I have a Samsung Series 7 NP730U3E which is running Ubuntu Gnome 13.10. This computer have an Intel Core i5 3337U an AMD Radeon HD 8570M on the inside. Ubuntu 13.10 is said to have driver support for this graphics card, but I am not sure whether or not this is the case. When I check System Settings Details it says "Graphics: Intel® Ivybridge Mobile" and lspci | grep VGA returns VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09).

• Sharing data between graphics and physics engine in the game?

  - by PolGraphic

  I'm writing the game engine that consists of few modules. Two of them are the graphics engine and the physics engine. I wonder if it's a good solution to share data between them? Two ways (sharing or not) looks like that: Without sharing data GraphicsModel{ //some common for graphics and physics data like position //some only graphic data //like textures and detailed model's verticles that physics doesn't need }; PhysicsModel{ //some common for graphics and physics data like position //some only physics data //usually my physics data contains A LOT more informations than graphics data } engine3D->createModel3D(...); physicsEngine->createModel3D(...); //connect graphics and physics data //e.g. update graphics model's position when physics model's position will change I see two main problems: A lot of redundant data (like two positions for both physics and graphics data) Problem with updating data (I have to manually update graphics data when physics data changes) With sharing data Model{ //some common for graphics and physics data like position }; GraphicModel : public Model{ //some only graphics data //like textures and detailed model's verticles that physics doesn't need }; PhysicsModel : public Model{ //some only physics data //usually my physics data contains A LOT more informations than graphics data } model = engine3D->createModel3D(...); physicsEngine->assingModel3D(&model); //will cast to //PhysicsModel for it's purposes?? //when physics changes anything (like position) in model //(which it treats like PhysicsModel), the position for graphics data //will change as well (because it's the same model) Problems here: physicsEngine cannot create new objects, just "assing" existing ones from engine3D (somehow it looks more anti-independent for me) Casting data in assingModel3D function physicsEngine and graphicsEngine must be careful - they cannot delete data when they don't need them (because second one may need it). But it's rare situation. Moreover, they can just delete the pointer, not the object. Or we can assume that graphicsEngine will delete objects, physicsEngine just pointers to them. Which way is better? Which will produce more problems in the future? I like the second solution more, but I wonder why most graphics and physics engines prefer the first one (maybe because they normally make only graphics or only physics engine and somebody else connect them in the game?). Have they any more hidden pros & contras?

• No image from graphics card but image from onboard video

  - by ReAzem

  I have an HD 5970 running on a P8Z68-v LE motherboard and I have no image comming out of the graphic card. When I plug my screen on my motherboard, I see the bios and the OS. When I plug my screen on the graphic card, I don't see anything. I know that the graphic card works because I have tested it on another computer. I know the motherboard works because I tested it with another graphic card and it worked. I know that the graphic card works with the computer because I have another computer with a P8Z68-LE and an HD 5970. I know it is not an OS issue because I should atleast be able to see the bios. I have tried unplugging my HDDs so that the OS dont interfere with anything. Using a 1000W power supply Using another HD5970 on the computer works. So this is a problem with my HD5970, but why is the graphic card working on my other computer?

• Laptop with Intel Graphics: external VGA monitor only gets signal on boot (no "hot plugging")

  - by iveand

  I am able to get an external VGA monitor (or projector) to work if I start my laptop with it connected. However, if I start the laptop with it disconnected there is no signal on the external. The Displays screen shows the external, and thinks that it is active, but there is no signal being sent to it. This has been a persistent problem since 10.04 (I am now on 12.04.... each upgrade hoping something is improved). I should note that even when it works (starting with display connected), Displays still says the monitor is "unknown" (but it sends the signal). For the correct resolution to display, I have had to add a few xrandr lines for my monitor to my .xprofile file... otherwise resolution is limited to default 1024x768. So, resolution issues can be worked around, but the main issue is that the external doesn't get a signal without starting the machine with it connected. I have tried: adding i915.modeset=1 to grub (also i965.modeset=1 since someone posted that this helped even though lshw shows i915) adding following ppa and doing a dist-upgrade: sudo add-apt-repository ppa:xorg-edgers/ppa Here are the details: Laptop: Toshiba Tecra M10 lspci listings for video: 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07) sudo lshw -C video listing: *-display:0 description: VGA compatible controller product: Mobile 4 Series Chipset Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 07 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:46 memory:ff400000-ff7fffff memory:e0000000-efffffff ioport:cff8(size=8) *-display:1 UNCLAIMED description: Display controller product: Mobile 4 Series Chipset Integrated Graphics Controller vendor: Intel Corporation physical id: 2.1 bus info: pci@0000:00:02.1 version: 07 width: 64 bits clock: 33MHz capabilities: pm bus_master cap_list configuration: latency=0 resources: memory:ffc00000-ffcfffff "System Info" shows my graphics as the following Mobile Intel® GM45 Express Chipset x86/MMX/SSE2

• Graphics performance of 945GME

  - by l0b0

  Edit: Since setting Appearance - Visual Effects up to a stunning "Normal", I now get ~35 FPS in glxgears right after login, with nothing else running :( I'm getting terrible graphics performance in NeverWinter Nights (native with SoU+HotU+CEP2) on my Eee PC 1005HAB. Even with all graphics settings (including the "advanced" ones) at minimum I get about 2-10 FPS, depending on the scene. Firefox is really sluggish as well - Changing tabs often takes a second, scrolling is laggy, and typing this I notice the delay between pressing keys and seeing the text on screen. The rest of the OS is running OK, although general performance seems to be even worse than my old Eee PC 900. glxgears gives about 60 FPS, which is apparently as it should be (synchronized with the monitor refresh rate). Bugs like Launchpad #252094 and the instructions for Reverting the Jaunty Xorg intel driver to 2.4 are old enough that I'm afraid following the instructions would render the system unusable. Are there any tips for improving graphics performance on this system that are still relevant for 10.10? $ uname -a Linux l0b0eee 2.6.35-28-generic #49-Ubuntu SMP Tue Mar 1 14:40:58 UTC 2011 i686 GNU/Linux $ lspci -nn | grep VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GME Express Integrated Graphics Controller [8086:27ae] (rev 03) $ glxinfo name of display: :0.0 display: :0 screen: 0 direct rendering: Yes server glx vendor string: SGI server glx version string: 1.4 ...

• 3D Vector "End Point" Calculation for procedural Vector Graphics

  - by FrostFlame64

  Alright, So I need some help with some Vector Math. I've developing some game Engines that have Procedural Fractal Generation for Some Graphics, such as using Lindenmayer Systems for generating Trees and Plants. L-Systems, are drawn by using Turtle Graphics, which is a form of Vector graphics. I first created a system to draw in 2D Graphics, which works perfectly fine. But now I want to make a 3D equivalent, and I’ve run into an issue. For my 2D Version, I created a Method for quickly determining the “End Point” of a Vector-like movement. Given a starting point (X, Y), a direction (between 0 and 360 degrees), and a distance, the end point is calculated by these formulas: newX = startX + distance * Sin((PI * direction) / 180) newY = startY + distance * Cos((PI * direction) / 180) Now I need something Similarly Equivalent for performing this Calculation in 3D, But I haven’t been able to Google anything that could show me how to do this. I'm flexible enough to get whatever required information is needed for this method calculation, in any reasonable form (Vector3, Quaternion, ect). To summarize: Given a starting point/vector position in 3D space (X, Y, Z), a Direction in 3D space (Vector3, Quaternion, ect), and a Distance, I need to find the “End Point” in 3D Space. Thank you for your time and help.

• Is it possible to install a discrete mobility card on a laptop without a graphics card already?

  - by JXPheonix

  To be specific: Can I: Install a discrete graphics card on a laptop that does not come with a discrete graphics card? Teach windows 8 to use the discrete card over the integrated graphics? To me this is the only downside of my laptop and I would not mind getting any graphics card as long as it is better than the integrated laptop card (an Intel 3000) The laptop if you need more information is an Asus U46E-BAL6.

• Edubuntu boots in low graphics mode. with an Intel HD Graphics system

  - by user63957

  I have a HD Intel graphics card in my laptop. It was working fine the first few days with the new version Edubuntu. Now when you start, just before it goes to the part asking for the login password I think the OP means lightdm it sends me to a low graphics mode. Things I've tried: I tried Ctl+Alt+F1. Updated and installed fglrx from the terminal. All my work is all stored there. Please, if anyone knows how to fix this, tell me. Original version: hola tengo una tarjeta intel hd graphics en mi laptop estuve trabajando los primeros dias bien con la nueva version edubuntu solo que ahora cuando inicia y justo antes de que pase a la parte que me pide la contraseña me manda low graphic mode no se que hacer ya entre y le di ctr alt f1 y actualice tmb instale fglrx necesito obtener toda miinformacion todo mi trabajo esta ahi guardado, por favor si alguien sabe como solucionar este bug digame como, gracias, ciao.

• Purple line on left side of screen when I use graphics card's hdmi port

  - by fab

  My graphics card is a nVidia GeForce GTX 660 2GB. When I plug HDMI into mobo it works fine. When I plug it into the graphics card (with 2nd monitor too) it shows a purple vertical line on the left side. It adds 2 pixels to the width and I can't adjust it with my monitor. It doesn't come up when I print screen. I tried changing the driver to the binary one (at the top) but that made it not show up at all. What do I do? Are some graphics cards just not compatible?

• Ubuntu 11.10 doesn't detect Intel integrated graphics (i7-2670QM CPU)

  - by Telmo Marques

  The laptop I'm using is an MSI GT683DX-847PT that comes with an NVIDIA GeForce GTX570M discrete GPU, and an Intel Core i7-2670QM CPU. According to Intel's description of the Core i7-2670QM CPU, it has an HD Graphics 3000 integrated GPU. The problem is that the Intel integrated graphics GPU doesn't come up in lspci nor in lshw, only the NVIDIA GPU shows up. Here is the output of both commands: sudo lspci: http://pastebin.com/raw.php?i=9AZg8bJy sudo lshw: http://pastebin.com/raw.php?i=6cAMFQsY I was counting on having two GPU's to run CUDA programs on the discrete NVIDIA GPU, while X was handled by the integrated Intel GPU, to prevent kernel execution timeout. Why doesn't the Intel HD Graphics 3000 GPU show up? Any tests I could make to verify the presence of an integrated GPU?

• OpenGL behaviour depending on the graphics card?

  - by Dan

  This is something that never happened to me before. I have an OpenGL code that uses GLSL shaders to texture a 3D model. The code involves a lot of GPU texture processing, blending, etc... I wanted to check how the performance of my code improves using a faster graphics card (both new and old are NVIDIA, using always the NVIDIA development drivers). But now I have found that once I run the code using the new graphics card, it behaves completely different (the final render looks wrong), probably because some blending effect is not performed correctly. I haven't really look into what has changed, but I am guessing that some OpenGL states are, by default, set different. Is this possible? Have you ever found different OpenGL/GLSL behaviour using different graphics cards? Any "fast" solution? (So far I've thought of plugging back the old one, push all OpenGL default states, and compare with the ones I initially get using the new card..)

• Which graphics library should I be using?

  - by DaveDev

  I have been developing and maintaining a WPF application, for which I've recently been tasked with adding a 3D representation of some of the data. I'm new to graphics programming in every kind of way so I'm curious whether I should stick with 3D graphics capabilities built into WPF or should I investigate other solutions, like OpenTK or SharpGL My objective is to represent the data so that it will eventually appear similar to: with nodes connected by lines. I need to rotate the image around each axis and each node will be a 3D model of the device it represents. So far, I've been able to experiment with the tutorial outlined here: Windows Presentation Foundation (WPF) 3D Tutorial and it was helpful as an introduction. But I can see that there are other ways to implement 3D graphics solutions and I wonder if they are more suitable for my needs, or should I stick with the in-built WPF solution? What are the pros and cons of each?

• 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.

• Which Graphics/Geometry abstraction to choose?

  - by Robz

  I've been thinking about the design for a browser app on the HTML5 canvas that simulates a 2D robot zooming around, sensing the world around it. I decided to do this from scratch just for fun. I need shapes, like polygons, circles, and lines in order to model the robot and the world it lives in. These shapes need to be drawn with different appearance attributes, like border/fill style/width/color. I also need to have geometry functions to detect intersections and containment for the robot's sensors and so that the robot doesn't go inside stuff. One idea for functions is to have two totally separate libraries, one to implement graphics (like drawShape(context, shape)) and one for geometry operations (like shapeIntersectsShape(shape1, shape2)). Or, in a more object-oriented approach, the shape objects themselves could implement methods to do their own graphics (shape.draw(context)) and geometry operations (shape1.intersects(shape2)). Then there is the data itself: whether the data to draw a shape and the data to do geometric operations on that shape should be encapsulated within the same object, or be separate structures (where one would contain the other, or both be contained inside another structure). How do existing applications that do graphics/geometry stuff deal with this? Is there one model that is best, or is each good for certain applications? Should the fact that I'm using Javascript instead of a more classical language change how I approach the design?

• Hybrid Graphics Functional won't work with my Asus UL30V anymore

  - by futuress

  The problem is that I am no longer able to boot in compatibility mode for just turning on my Nvidia graphics to install the driver. Because no login screen will appear if Ubuntu is loading. In Ubuntu 11.10 I was able to activate nvidia graphics only' option this way: 1) Change BIOS to 'compatibility mode' which will turn off the Intel card. 2) Install the Nvidia proprietary driver using Ubuntu's driver finder (Additional Drivers) and then reboot. I was not interested using only the Intel graphics, for the sake of battery life. Now I have both cards running and they drain my battery life dramatically. And the main problem of this configuration no OpenGL is available, so I can't play any games any more. At this point, I have a pre-solution. I uninstalled the nvidia drivers and installed bumblebee. Now the Intel card is recognized. I would prefer to run just the nvidia card as in Ubuntu 11.10 but for now this is better than nothing. Does anybody else have the same problem?

• Ubuntu 13.10, kernel 3.11 blank screen issue with hybrid graphics

  On my HP Envy, which has both an Intel on-chip graphics card and an Nvidia Geforce: *-display UNCLAIMED description: 3D controller product: GK208M [GeForce GT 740M] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: cap_list configuration: latency=0 resources: memory:d2000000-d2ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:5000(size=128) memory:b2000000-b207ffff *-display description: VGA compatible controller product: 4th Gen Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 06 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:46 memory:d3000000-d33fffff memory:c0000000-cfffffff ioport:6000(size=64) I have trouble with all newer kernels. I basically had to install 12.04 LTS and use their 3.5 kernel family to get the system to boot. The 3.8 from 12.10 or the newest 3.11 from Ubuntu 13.10 leave me with a black screen upon boot. On one occasion I did hear the "log in" sound, but the screen did not display anything. I have purged all nvidia drivers so I guess it should just use the intel drivers, but apparently this is all messed up with newer kernel versions. This is different from the other "nvidia boots into blank screen" bug in that I don't rely solely on an nvidia card. Surely the intel on-chip card should be supported and leave me with something different from a blank screen? Again, it only works with kernel versions 3.5.0-41-generic, not with the 3.11.0-12 one that ships with Ubuntu 13.10. When I go into the grub menu and change the boot options from 'quiet splash' to 'nomodeset' I am able to boot the system, but then I don't get any graphics and trying 'sudo service lightdm start' doesn't succeed (I get 100% CPU for apport, but this doesn't do anything either, so I kill it). Help, I'm all out of ideas. EDIT: Let me add that I'm using the EFI boot system and have a dual-boot installation with Windows 8.

  - by Endle

  Hello wonderful people. I know there are several other posts with similar questions. I also know how to use Google. I also have read up on posts discussing bumblebee, crossfire, ati catylist and many other interesting topics. I would just like someone to give me advice on how to use the onboard and pci-e graphics at the same time. I know the computer is capable of doing this. It works in Windows. I can use the VGA and DVI onboard port and the HDMI port of the add on card all at the same time. Works great in Windows 7, In Ubuntu, it seems only one or the other will work. I can use any combination of two displays on either adapter: VGA and HDMI..HDMI and DVI..so forth and so on. I have started experimenting with xorg.conf files, but have not been able to get any of them to work. Here is my last attempt at writing an xorg.conf file: Section "ServerLayout" Identifier "X.org Configured" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" LeftOf "Screen0" Screen 2 "Screen2" LeftOf "Screen1" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "Device" Identifier "Onboard Video" Driver "radeon" BusID "PCI:01:05.0" EndSection Section "Device" Identifier "Graphics Card" Driver "radeon" BusID "PCI:02:00.0" EndSection Section "Monitor" Identifier "CRT2" Option "VendorName" "ViewSonic" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Monitor" Identifier "DVI1" VendorName "ACR" ModelName "P224W" Option "DPMS" EndSection Section "Monitor" Identifier "DVI2" Option "VendorName" "Acer" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Screen" Identifier "Screen0" Device "Onboard Video" Monitor "CRT2" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1280x1024" EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Graphics Card" Monitor "DVI1" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1920x1080" EndSubSection

• Less graphics power all the sudden (Intel HD 3000)

  - by queueoverflow

  I have a Intel Sandy Bridge i5 with the HD 3000 graphics card. I used to be able to play Urban Terror and Nexuiz comfortably with 85 and 60 frames per seconds until mid/end of October 2012, the former even on a full HD display with that many frames. Now I have around 30 to 45 on the smaller laptop screen and around 20 to 30 on the external monitor. Did something happen to Kubuntu 12.04 so that it has less graphics performance than previously? Update I looked into the system monitor and could not detect anything being at the maximum. The four CPU cores were pretty much bored, the 8 GB RAM were filled with maybe 2 GB. And I ran intel_cpu_top and did not notice anything at its limit. See the output. after Kernel bisecting I now did a kernel bisect and tried 3.2.0-23, 3.2.0-27, 3.2.0-29 and 3.2.0-30 and all had full graphics power. Interestingly, I then had full power when I just booted back into the regular 3.2.0-32 kernel. This does not make sense to me …
