• Ubuntu 12.10 Trackpoint not detected Thinkpad X130e

  - by killerknives

  I just did a fresh install of 12.10 and now only my touchpad works. The trackpoint and Left/Right buttons below the trackpoint do not work. The trackpoint worked fine as of 12.04. I've searched online and there was a hack that said that disabling the touchpad would enable the trackpoint. WRONG! You'll end up having to use the keyboard =/. I don't know what is needed so I'll just dump some stuff. lspci: 00:00.0 Host bridge: Advanced Micro Devices [AMD] Family 14h Processor Root Complex 00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Wrestler [Radeon HD 6310] 00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI Wrestler HDMI Audio [Radeon HD 6250/6310] 00:05.0 PCI bridge: Advanced Micro Devices [AMD] Family 14h Processor Root Port 00:06.0 PCI bridge: Advanced Micro Devices [AMD] Family 14h Processor Root Port 00:07.0 PCI bridge: Advanced Micro Devices [AMD] Family 14h Processor Root Port 00:11.0 SATA controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 SATA Controller [AHCI mode] 00:12.0 USB controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB OHCI0 Controller 00:12.2 USB controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB EHCI Controller 00:13.0 USB controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB OHCI0 Controller 00:13.2 USB controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB EHCI Controller 00:14.0 SMBus: Advanced Micro Devices [AMD] nee ATI SBx00 SMBus Controller (rev 42) 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) (rev 40) 00:14.3 ISA bridge: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 LPC host controller (rev 40) 00:14.4 PCI bridge: Advanced Micro Devices [AMD] nee ATI SBx00 PCI to PCI Bridge (rev 40) 00:18.0 Host bridge: Advanced Micro Devices [AMD] Family 12h/14h Processor Function 0 (rev 43) 00:18.1 Host bridge: Advanced Micro Devices [AMD] Family 12h/14h Processor Function 1 00:18.2 Host bridge: Advanced Micro Devices [AMD] Family 12h/14h Processor Function 2 00:18.3 Host bridge: Advanced Micro Devices [AMD] Family 12h/14h Processor Function 3 00:18.4 Host bridge: Advanced Micro Devices [AMD] Family 12h/14h Processor Function 4 00:18.5 Host bridge: Advanced Micro Devices [AMD] Family 12h/14h Processor Function 6 00:18.6 Host bridge: Advanced Micro Devices [AMD] Family 12h/14h Processor Function 5 00:18.7 Host bridge: Advanced Micro Devices [AMD] Family 12h/14h Processor Function 7 01:00.0 Network controller: Realtek Semiconductor Co., Ltd.

• Strange Ubuntu Random Display [Video]

  - by d4v1dv00

  I had this random display issue ever since Ubuntu 11.04 and now running Ubuntu 11.10 and this problem still persist. It is very hard for me to explain, so I uploaded a video to elaborate itself. Before I convert from Windows 7, this issue never happened. The symptom is so random that I cannot reproduce or tell precisely when will this happen again. My wild guess is, should this be related to driver? Below are my detail system information: $ lspci 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b5) 00:1d.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation H67 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 02:00.0 Ethernet controller: Broadcom Corporation NetLink BCM57788 Gigabit Ethernet PCIe (rev 01) is there any other information i need to post and how do i do that?

• Ubuntu and bumblebee and intel problem

  - by LnxSlck

  I have a brain teaser that i can't solve. When 12.04 (64bits) came out, i did a fresh install and then installed bumblebee with: sudo add-apt-repository ppa:bumblebee/stable sudo apt-get install bumblebee bumblebee-nvidia And Ubuntu recognized (System Settings - Details) Intel Card for primary card, and i could launch applications with optirun. I have: 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 GF119 [GeForce GT 520MX] (rev ff) Now, a few days back, i did the exact same thing, installed from the same DVD everything the same, installed bumblebee the same way. Nvidia with Optirun works fine, but Ubuntu doesn't have 3D effects: root@deathstar:~# optirun /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce GT 520MX/PCIe/SSE2 OpenGL version string: 4.2.0 NVIDIA 295.40 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: no GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no I never did anything to install Intel drivers (except installing mesa-utils), before bumblebee got everything working, but now i can't get Ubuntu to get Unity with 3D. Can someone help me please get Unity 3d working? Your help will be much appreciated

• 2 folders in Sys/Class/Backlight?

  - by zebrapie

  ISSUE: Backlight brightness does not change. More Detail: Brightness will not change, using both 'System Settings-Screen', or FN keys (Brightness bar shows and moves, but screen brightness does not change). Notcied a post in this thread (http://ubuntuforums.org/showthread.php?t=1866283) about having multiple folders in Sys-Class-Backlight... I HAVE TWO FOLDERS TOO! 'intel_backlight' and 'acpi_video0' Using the function keys, alters the value in the acpi_video0's 'Brightness' file - But doesn't actually alter the brightness of the screen. If I add 'backlight=vendor' in Grub, my function keys then edit the value in the 'Intel_Backlight brightness file. - But again doesnt actually change the brightness of the screen. Computer: Fujitsu Siemans Pi2515, Intel Integrated Graphics, No hdd partition. Already Tried: -Editing grub to contain: acpi_osi=Linux acpi_backlight=vendor -http://ubuntuguide.net/change-screen-brightness-with-fn-key-in-ubuntu-11-0410-10 -sudo apt-get install acpi -$ sudo setpci -s 00:02.0 F4.B=20 -Brightness does not adjust in fallback mode either. -Reinstalling OS, Using Linux Mint (Same problem). -Upgrading and downgrading BIOS. Many thanks for reading, I understand this problem may need a bit of a Linux pro to sort. If anyones up for the challenge i'll spend any amount of time being walked through this, posting results. Don't want to give up here!

• Is 2 lines of push/pop code for each pre-draw-state too many?

  - by Griffin

  I'm trying to simplify vector graphics management in XNA; currently by incorporating state preservation. 2X lines of push/pop code for X states feels like too many, and it just feels wrong to have 2 lines of code that look identical except for one being push() and the other being pop(). The goal is to eradicate this repetitiveness,and I hoped to do so by creating an interface in which a client can give class/struct refs in which he wants restored after the rendering calls. Also note that many beginner-programmers will be using this, so forcing lambda expressions or other advanced C# features to be used in client code is not a good idea. I attempted to accomplish my goal by using Daniel Earwicker's Ptr class: public class Ptr<T> { Func<T> getter; Action<T> setter; public Ptr(Func<T> g, Action<T> s) { getter = g; setter = s; } public T Deref { get { return getter(); } set { setter(value); } } } an extension method: //doesn't work for structs since this is just syntatic sugar public static Ptr<T> GetPtr <T> (this T obj) { return new Ptr<T>( ()=> obj, v=> obj=v ); } and a Push Function: //returns a Pop Action for later calling public static Action Push <T> (ref T structure) where T: struct { T pushedValue = structure; //copies the struct data Ptr<T> p = structure.GetPtr(); return new Action( ()=> {p.Deref = pushedValue;} ); } However this doesn't work as stated in the code. How might I accomplish my goal? Example of code to be refactored: protected override void RenderLocally (GraphicsDevice device) { if (!(bool)isCompiled) {Compile();} //TODO: make sure state settings don't implicitly delete any buffers/resources RasterizerState oldRasterState = device.RasterizerState; DepthFormat oldFormat = device.PresentationParameters.DepthStencilFormat; DepthStencilState oldBufferState = device.DepthStencilState; { //Rendering code } device.RasterizerState = oldRasterState; device.DepthStencilState = oldBufferState; device.PresentationParameters.DepthStencilFormat = oldFormat; }

• Multiple Settings for One Monitor

  - by Lynda

  I have my monitor set to the way I like it, it shows colors accurately and not overly bright (white doesn't blind me). However I edit photos for the web and this is great for my screen but I have noticed when looking at other screens my photos will at times looked washed out and not a good presentation. If I manually change my monitor settings to be brighter (and a few other tweaks) I can replicate the look of other monitors close enough to help prevent washed out/blown out photos. Here is the issue, I need to be able to change settings between the two fairly easily. To manually set my monitor for one then back to the other can be time consuming and a pain to set right every time. I would like to be able to preset certain settings (in software) that I can quickly switch between by pressing hotkeys or clicking shortcut on my desktop. I have an AMD video card and have attempted to use the AMD VISION Engine Control Center to add presets then tweak the settings for each. However when I switch between the presets the settings are the same. How do I build presets using the VISION Engine Control Center that actually works (maybe I misunderstand what it is saving?) or is there a way to do this in Windows 7 or free software that actually works decently for this purpose?

• Why doesn't 12.04 recognize my ATI Radeon X300SE graphics card?

  - by Nomad Zero

  So far everything including the BCM4321 card is working, however, the OEM ATI Radeon X300SE (RV370) is not recognized. When I go into system details the card comes up as unknown. When I run lspci the card shows up as: 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV370 5B60 [Radeon X300 (PCIE)] 01:00.1 Display controller: Advanced Micro Devices [AMD] nee ATI RV370 [Radeon X300SE] I have attempted check Additional Drivers but the card does not show up as needing a driver. So far this is causing the system to run warmer as the processor is doing a bit of the work to run Unity and any full screen videos tend to be rather choppy. Is there an available driver that will fix my issue and what is the install method? I am not scared to run a terminal so no worries there, as long as I have instructions, I can find my way. I am running under 12.04 LTS Kernel 3.2.0-25-generic-pae

• Problems reviving old pc including graphics card issue.

  - by Mick

  I have a PC that seemed to have died years ago that I am trying to revive. It has a dual core athlon processor and a gigabyte motherboard. It had two dual output graphics cards, and I have long since forgotten which output would print out the diagnostic information as the PC starts up. Also I suspect that the resolution set on all the monitors was probably higher than my current single monitor is capable of displaying. The motherboard also has a built in graphics card, so I thought it may be simplest to remove both the graphics cards and plug my monitor into the onboard graphics just while I get things going. Does that seem sensible? Now the other problem: The PC has two hard drives. I have no idea which one is the primary one it is attempting to boot from. When I power up, the fan comes on and I hear some chuga-chuga-pause chuga-chuga-pause repeat indefinitely. I'm not sure which device is making the noise. There are no-beeps at any time. I see nothing on the screen at any time, not even for a second. Any suggestions? EDIT: If T start up the PC without the power connected to the CDrom there is no chuga-chugan noise.

• Graphics Driver problem, ATI Radeon HD 3200, small screen size and slows everything down.

  - by Arvind Jangid

  Regards. I am using a: 2009 Compaq Presario CQ40-415AU Notebook AMD Athlon X2 Dual core Processor 2.1 GHz 1024 MB L2 cache 3GB DDR2 RAM ATI Radeon + HD 3200 Graphics 256 MB, screen is 14 inch widescreen with resolution of 1280*800. I installed Ubuntu 12.04 LTS 32bit on my laptop. It works brilliantly until I installed graphics driver. When I installed the driver, the graphics became slow. Everything slowed down. Even the splash screen resolution changed to something like 640*480. I have liked Ubuntu since 9.10 and for the freedom it provides and its versatility, but graphics problem remains the same. I even installed Ubuntu on a 50 GB partition with 6 GB swap partition. My HDD is 320 GB. Please tell me what is wrong.

• Are VM-based languages becoming viable for Graphics since the move to GPU computing?

  - by skiwi

  Perhaps the title is not the most clear, so let me elaborate it more: I am talking about VM-based languages, by that I mean languages that run on the JVM (java) and for example C#. Also I am talking about 3D graphics, just to be clear. Lately the trend has been that most computing is being done on the GPU and not on the CPU, and since times the issue with programming games on a VM-based language is that garbage collecting may happen randomly. So let's take a look which is responsible for what: Showing the graphics: GPU Uploading graphics to the GPU: CPU? Needs to be done every frame? Calculating physics constraints: GPU Doing the real game logic (Determining when to move objects (independent of physics calculations), processing AI): CPU Is my list actually correct? And if it is, is for example Java becoming more viable? Or is uploading the graphics (vertices) still the most expensive operation? Would like to get more insight into this.

• Does running Nexuiz gives extra pressure on Processor if you dont have external Graphics card?

  - by Curious Apprentice

  Its a rather stupid question, though I want to be sure. Does having a external graphics card can lower the stress over the processor? what kind of graphics card Ubuntu supports ? Well I'm planning to buy a graphics card for Windows 7 as I have started learning Adobe Premiere Pro. Which G card should I buy? Do i consider the card or the availability of the card drivers for Ubuntu Linux ? If I install a Graphics card and does not install its drivers can I left it unused on Ubuntu ? I don't think theres a much need for G card on Ubuntu Though.

• Is Ubuntu recognizing and/or using my NVIDIA graphics card?

  - by user212860

  This is my first post here, and I'm pretty new to Ubuntu/Linux. I currently have no other OS except for Ubuntu 13.10. (I used to have Win7 until i got a new terabyte hard drive). My current PC build, if any of this helps: CPU: Intel i5 quad-core Graphics: NVIDIA GeForce GTX 650 RAM: 8 GB HDD: 1 TB SATA 3 Motherboard: MSi Z77 A-G41 OS Ubuntu 13.10 So I recently installed Ubuntu 13.10 and put Steam on it, and I'm seeing that my games run a lot slower than they did when I had Win7. I figured it was a graphics problem, so I checked System Settings Details Overview. It says in "Graphics" that I have "Gallium 0.4 on NVE7" (don't really know what that is). Does this mean that Ubuntu is not using my graphics card? In System Settings Software & Updates Additional Drivers, it clearly shows like this: NVIDIA Corporation: GK107 [GeForce GTX 650] -This device is using an alternative driver (And then it shows a list of drivers that I can switch back and forth to) So this is a bit confusing. In Software and Updates, it clearly shows that I have my NVIDIA card installed, and that I have a driver selected for it. But in System Settings, it shows I have some Gallium 0.4 thing. I had done a bit of research, and ended up typing command: "lspci|grep VGA" in the Terminal. It showed this in response: VGA compatible controller: NVIDIA Corporation GK107 [GeForce GTX 650] (rev a1) The Terminal seems to recognize my graphics card. What it looks like to me, is that I don't have the proper driver, and I might be using my CPU's integrated graphics. When I switch around which driver I am using in that list, it still does not see my card in System Settings. Some of the drivers in the list give me some sort of OpenGL error when I try to run a game. It might just be that my games are running slow because the game developers have not optimized it for Ubuntu that well. However, that still doesn't take away from the fact that System Settings is not showing my NVIDIA card. TL;DR Version: How do I know if my video card is being recognized/used? If my video card is not being used, what is the best way fix that? Please make your answers easy to understand. I do not mind wordy responses, as long as I can follow what you're saying. Any help would be greatly appreciated! Thanks, Jabber5

• Fried graphics card, how to proceed ?

  - by user19496

  Motherboard: Biostar TPower I45 I fried my graphics card (white smoke), by removing the cable marked PCI-E from the card, and then booting. Removed the graphics card, and now the machine is booting, and I can ping it. However I have no possibility to see what is actually happening, because I can't attach a monitor. Can I workaround the lack of monitor in some way, just to see if the motherboard is fine, attach a cable and telnet in or any other way ? Or, do I have to buy and install a new graphics card to be sure ?

• Linux Programs for pulling measurements from graphics

  - by Zack

  As a front-end developer, I'm often given graphics of web sites and told pretty much, "Make it work." I've recently started working on Linux 100% of the time and was wondering if there's any programs out there that're good for "digesting" graphics. All I do, pretty much, is draw little selection boxes and takes notes on their dimensions; I also slice out a piece of the graphic (i.e. copy out just the part of the graphic I need for to make the same effect in CSS). Before now I've been very happy with Fireworks, but I need something for Linux, any suggestions? As a note, I mainly deal with pixel based graphics, so the program being vector based isn't a necessity.

• Upgrade the Graphics Card for a Dell Dimension 3100

  - by Pat Foran

  Hi, I have a Dell Dimension 3100 Desktop with a 128MB Graphics Card Integrated into the Mother Board. I need to upgrade this 128MB to at least 256MB or 512MB if the system will support same. I am told by Dell that all I have is a PCIx1 slot and that they do not stock a Graphics Card for this. I was told to shop around at Amazon and ebay etc and I would find one there. I have shopped around for some time now and do not know exactly what I am looking for. There are several PCI Graphics Card out there but which one would be the correct one for a Dell Dimension 3100. Can you help me resolve this problem. If you know of a PCIx1 card that will sort out my problem you might please let me have all the details for to purchase it. Regards, Pat,

• Windows Experience Index Dropped After Adding Dedicated Graphics Card

  - by Ludo

  I purchased a new PC with a Gigabye Z68X-UD3H-B3. I had a Radeon HD 5450 graphics card spare, so I've added that instead of using the onboard graphics as I just presumed it would be better. But, my windows experience index has gone down. From 5.4 to 5. Dekstop Performance has dropped from 5.4 to 5, although gaming graphics has gone up from 5.9 to 6.2. I'm not actually going to be using the machine for gaming, just audio production, but I added the card as I'll possibly be doing video editing in future too. Why would this be? Can I trust windows experience index scores? Or is it possible the onboard stuff is just better for general desktop stuff? Thanks! Ludo.

• Integrated Graphics and Audio as Media Center?

  - by Will

  I'm considering setting up a PC as a Media Center. Mainly to watch movies (ideally HD quality) and listening to music, but also to perform tasks like e-mail, web browsing, ... I quite like the looks and the price of this barebone: http://www.asus.de/Barebone_PC/S_Series_7L/S2P8H61E However it comes with integrated graphics and audio and only has one free PCI-Express slot. Which would mean in the worst case, where both integrated graphics and audio turn out to be insufficient, I could only upgrade one. So is integrated graphics and audio sufficient for a media center solution? Cheers, Will

• Microsoft Ergonomic 7000 keyboard + mouse lag

  - by user115210

  I recently bought a new Microsoft Ergonomic 7000 keyboard. I started to use it with my Ubuntu 12.04 and it lags all the time. I try to be more specific: Even on a minor CPU usage the mouse lags. By minor I mean firefox loading a webpage, or opening an application like conky, gnome-terminal etc. When higher CPU usage occurs the keyboard is lagging too, but by this I mean it misses my hits, so what I type won't appear later. What I tried so far (and did not work)? Disable autosuspend (echo -1 to sys/bus/usb.../autosuspend) and at the same place set level to "on". I have tried several video drivers: Vesa, radeon, newest catalyst (and catalyst beta too) When my keyboard and/or mouse lags I tried an other USB keyboard which works perfectly and the same for the mouse. I tried the keyboard and mouse on a different computer with Linux (Ubuntu, Arch, OpenSuse) too, the same problem appears but not on Windows. I tried to replace the battery sets, and to change channel on the dongle. And also tried to use the dongle from other USB ports. On the same time I am able to use any other wireless mouse. I changed the XkbModel to "microsoft7000" but it did not solve anything.

• Black screen with thinkpad edge e525, AMD radeon HD before and after installation, plymouth?

  - by carolien

  I have a new thinkpad edge e525 (which should work) and wanted to try ubuntu (first linux experience). With the ubuntu desktop-cd I had a blackscreen before installation, I could fix that with nomodeset. After the installation, when rebooting I got the black screen again. First I see some ubuntu colour with a green busted stripe. I have the same problem with the live boot, also tried mint live, the stripe gets pink. I installed xubuntu 64bit from an alternate cd and I didnt have problems until de reboot after the installation. Same problem, just a black screen with the green stripe than blackscreen. I tried several things: adding nomodeset to the bootmenu, but than I get: No connection to plymouth and it is stuck at checking the battery status. I tried to replace quiet splash with text. Didnt work either. actually one time I saw a blue booting image before that. I managed to get a root command though via the recovery boot. I didnt dare to just remove the plymouth package. Can I just delete plymouth or do I have to deinstall it as described in several ways. (Problem is, right now the notebook doesnt have a internet connection. And I dont know how to manage it with a usb stick?) Or do I have to install the AMD catalyst driver manually? (Again, how can I do that with an usb stick) I also tried this: Ubuntu hits a black screen after boot. Is there any solution without internet? And if I need internet which is the right one? Please explain step by step what I have to write and so on! Thank you! also tried: set gfxpayload=text and: just remove splash and adding vesafb.nonsense=1 to the grub editor, because I couldnt find it anywhere

• OpenGL or OpenGL ES

  - by zxspectrum

  What should I learn? OpenGL 4.1 or OpenGL ES 2.0? I will be developing desktop applications using Qt but I may start developing mobile applications in a few months, too. I don't know anything about 3D, 3D math, etc and I'd rather spend 100 bucks in a good book than 1 week digging websites and going through trial and error. One problem I see with OpenGL 4.1 is as far as I know there is no book yet (the most recent ones are for OpenGL 3.3 or 4.0), while there are books on OpenGL ES 2.0. On the other hand, from my naive point of view, OpenGL 4.1 seems like OpenGL ES 2.0 + additions, so it looks like it would be easier/better to first learn OpenGL ES 2.0, then go for the shader language, etc Please, don't tell me to use NeHe (it's generally agreed it's full of bad/old practices), the Durian tutorial, etc. Thanks

• Issue with distinguishing levels in isometric game

  - by Konrad

  I'm working on an isometric game however I am having trouble visually distinguishing between levels in the game. Take the example below, the first image shows concrete blocks at ground level and the following images show an attempt to build a few blocks a level above. As you can see the level above is visually swallowed the one below. I've tried shading to make lower levels darker with respect to camera, but this doesn't work that well.. any ideas?

• OpenGL - have object follow mouse

  - by kevin james

  I want to have an object follow around my mouse on the screen in OpenGL. (I am also using GLEW, GLFW, and GLM). The best idea I've come up with is: Get the coordinates within the window with glfwGetCursorPos. The window was created with window = glfwCreateWindow( 1024, 768, "Test", NULL, NULL); and the code to get coordinates is double xpos, ypos; glfwGetCursorPos(window, &xpos, &ypos); Next, I use GLM unproject, to get the coordinates in "object space" glm::vec4 viewport = glm::vec4(0.0f, 0.0f, 1024.0f, 768.0f); glm::vec3 pos = glm::vec3(xpos, ypos, 0.0f); glm::vec3 un = glm::unProject(pos, View*Model, Projection, viewport); There are two potential problems I can already see. The viewport is fine, as the initial x,y, coordinates of the lower left are indeed 0,0, and it's indeed a 1024*768 window. However, the position vector I create doesn't seem right. The Z coordinate should probably not be zero. However, glfwGetCursorPos returns 2D coordinates, and I don't know how to go from there to the 3D window coordinates, especially since I am not sure what the 3rd dimension of the window coordinates even means (since computer screens are 2D). Then, I am not sure if I am using unproject correctly. Assume the View, Model, Projection matrices are all OK. If I passed in the correct position vector in Window coordinates, does the unproject call give me the coordinates in Object coordinates? I think it does, but the documentation is not clear. Finally, to each vertex of the object I want to follow the mouse around, I just increment the x coordinate by un[0], the y coordinate by -un[1], and the z coordinate by un[2]. However, since my position vector that is being unprojected is likely wrong, this is not giving good results; the object does move as my mouse moves, but it is offset quite a bit (i.e. moving the mouse a lot doesn't move the object that much, and the z coordinate is very large). I actually found that the z coordinate un[2] is always the same value no matter where my mouse is, probably because the position vector I pass into unproject always has a value of 0.0 for z. Edit: The (incorrectly) unprojected x-values range from about -0.552 to 0.552, and the y-values from about -0.411 to 0.411.
