  • Blank screen after installing nvidia restricted driver

    - by LaMinifalda
    I have a new machine with a MSI N560GTX Ti Twin Frozr II/OC graphic card and MSI PH67A-C43 (B3) main board. If i install the current nvidia restricted driver and reboot the machine on Natty (64-bit), then i only get a black screen after reboot and my system does not respond. I can´t see the login screen. On nvidia web page i saw that the current driver is 270.41.06. Is that driver used as current driver? Btw, i am an ubuntu/linux beginner and therefore not very familiar with ubuntu. What can i do to solve the black screen problem? EDIT: Setting the nomodeset parameter does not solve the problem. After ubuntu start, first i see the ubuntu logo, then strange pixels and at the end the black screen. HELP! EDIT2: Thank you, but setting the "video=vesa:off gfxpayload=text" parameters do no solve the problem too. Same result as in last edit. HELP. I would like to see Unity. This is my grub: GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="video=vesa:off gfxpayload=text nomodeset quiet splash" GRUB_CMDLINE_LINUX=" vga=794" EDIT3: I dont know if it is important. If this edit is unnecessary and helpless I will delete it. There are some log files (Xorg.0.log - Xorg.4.log). I dont know how these log files relate to each other. Please, check the errors listed below. In Xorg.1.log I see the following error: [ 20.603] (EE) Failed to initialize GLX extension (ComIatible NVIDIA X driver not found) In Xorg.2.log I see the following error: [ 25.971] (II) Loading /usr/lib/xorg/modules/libfb.so [ 25.971] (**) NVIDIA(0): Depth 24, (--) framebuffer bpp 32 [ 25.971] (==) NVIDIA(0): RGB weight 888 [ 25.971] (==) NVIDIA(0): Default visual is TrueColor [ 25.971] (==) NVIDIA(0): Using gamma correction (1.0, 1.0, 1.0) [ 26.077] (EE) NVIDIA(0): Failed to initialize the NVIDIA GPU at PCI:1:0:0.

Thank you all for the great help and support. EDIT9 In the meanwhile I have a complete new system with "only" a MSI N460GTX Hawk, but more RAM. The system works perfect. :-) The original N560GTX had a hardware defect. Is is possible to close this question? THX!

  • 12.10 Booting Into Variations Of Blank Screen

    - by user93954
    I've been running the Ubuntu 12.10 beta since about a month before the final release with almost no problems. However since the day of release (I'm assuming an update has caused this) I have had problems booting into the actual GUI interface. Trying to get it to work is just a case of hard shutting down until it works, but for most of the time I need to battle with various different kinds of black screens. These include a plain black screen, a flashing line and a flashing line that doesn't fit the resolution. Nine times out of ten the cursor will be displayed over these. It also sometimes manages to boot into Ubuntu, albeit text mode or sometimes it loads GRUB which it isn't setup to do. If anyone could help out with this it'd be great. I really, really don't want to have to go through yet another clean installation. Cheers.

  • How can I fix broken i915 drivers for Intel GPUs?

    - by Alen Mujezinovic
    I've got troubles getting the i915 drivers to work correctly on my laptop (HP Pavilion DM4 2101ea). Specifically, the laptop screen goes black and stays black after the splash graphic when booting both from USB key and from harddrive. To get anything on to the display after the splash screen I have to boot either with acpi=off nomodeset i915.modeset=0 I'd rather not turn ACPI off because I like my fans spinning and nomodeset is a bit overkill, so for now I'm booting with i915.modeset=0. Unfortunately, this turns off KMS and my current maximum resolution on the laptop screen is fixed to 1024x768 instead of its real capability. When not setting any of the above boot flags and I plug in an external monitor, the external monitor works fine. When booting with the flags, the external monitor works fine too, but can only do 1024x768 and can't do anything else than mirroring the laptop display. I did upgrade the i915 drivers from 2.17 that ship with Precise to 2.19 which are the most recent ones but without luck of getting anything to display. Here's my lspci output: 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.2 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 3 (rev b5) 00:1c.4 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 5 (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 HM65 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) 01:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) 02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

I've never had problems with Intel hardware on Ubuntu before so this is very surprising. If you could provide a method to make i915 work, suggest alternative drivers a way to boot with i915.modeset=0 but higher resolutions and KMS on or explain what is happening and how to fix it I'll give you an answer badge. :) Thanks

    - by D3s7
    i have a problem with my Ubuntu 12.04 Wubi installation, sometimes when booting, the computer will get to the purple screen without the Ubuntu logo, then will go to a black screen and then lots of white saccaged colors will appear and i will be taken to the login page. But sometimes, it just get stuck on the black screen and does nothing and i have to hard shutdown and retry it until it works. What may cause this problem and why? I can shutdown correctly. Thanks for helping. Edit: RADEON HD 7650M Graphic card with latest available Drivers on amd's driver download site (fglrx drivers caused shutdown problems so i removed them).

  • Dead (nearly blank) laptop screen, secondary screen works - how to fix?

    - by LIttle Ancient Forest Kami
    My laptop screen is black while my secondary screen is fine. What I tried: setting brightness (Fn keys) - no effect, no change seen, also on secondary screen removing static electricity like suggested here - no effect restarting / charging battery, running on battery / "wall" power - no effect as well wait to see if warming it up helps - it doesn't follow official Ubuntu diagnostics - checking now... What I will try next: check last updates I've made IIRC I am running on nomodeset already, but can't recall how to verify this Further symptoms: can't see BIOS screen system loads and works fine, just screen has problems screen works (occasionally I could glimpse very dimly what was going on, but it was like with minimum brightness set - nearly non-distinguishable from just a black screen) Any ideas how to proceed best? What is most probable cause?

  • Using the JRockit Flight Recorder as an In-Flight Black Box

    - by Marcus Hirt
    The new JRockit Flight Recorder has some very interesting properties. It can be used like the black box of an airplane, allowing users to go back in time and check what was happening around the time when something went wrong. Here is how to enable the default continuous recording in JRockit to allow for that use case. The flight recorder is on by default in JRockit R28, the problem is that there is no recording running by default. To configure JRockit to start with the default recording running, add the parameter: -XX:FlightRecorderOptions=defaultrecording=true That will enable a recording with recording ID 0. You can see that it has been started properly by choosing Show Recordings from the context menu in JRockit Mission Control.   You should see something similar to the picture below. Simply right click on the recording and select dump to dump information available in the flight recorder. You can select to dump data for a specific period of time or all data. For more information about the command line parameters available to control the Flight Recorder, see the JRockit documentation.

  • Antec Fusion Black LCD won't turn off on system shutdown

    - by Niklas
    Hi! I've been struggling a while with getting the iMON LCD/IR-receiver on my Antec Fusion Black case to shutdown together with the system (XBMC Live 10 - ubuntu based). But it won't. When it's turned off the LCD still lights up the whole room. Many have proposed the "solution" of setting the machine into hibernation instead but that however won't work for me, since I'm unable to suspend my system. It is the LCD/IR-module that prevents me from suspending and I haven't found a solution to properly unload it on suspending (it's way above my linux knowledge). I need help with getting the display to turn off the backlight when the system is turned off. Can anyone please help me? If anyone also has the knowledge on how to get the eject function to work on my Antec Veris rm200 remote I would be very grateful, I was told about that it could get fixed with irexec but I do not know how since I haven't been able to find a good tutorial on the subject. Thank you for helping me!

  • Ubuntu 12.10 boots to purple or black screen but intermittently boots fine

    - by Nic
    I have a fresh install of Ubuntu 12.10 64bit dual booting with Win7 64bit. Windows boots fine every time. When I choose Ubuntu from Grub2 menu it will sometimes boot just fine. Most of the times though it gets stuck at a purple screen with nothing happening and no keys or key combinations working. Other times instead of the purple screen I get a black screen with a flashing cursor at the top. Nothing happens. I need to hold down the power button to restart and after a couple times of trying it will eventually boot into Ubuntu. Once that happens everything runs without any problems. I have tried different approaches to fix the problem but to no avail. I tried removing "quiet splash", used no splash, and nomodeset What I got from this was seeing all the text of the boot process but more often than not the process gets stuck right after recognizing all the USB ports and devices. If it gets stuck nothing happens (except when i plug in a usb device: it still recognizes it with a new line of text) In the case when the boot process works, after it lists the usb devices it tells me something like: recovery of read-only filesystem necessary. (its the filesystem that ubuntu runs on) then it does the recovery and i get: recovery complete. after that Ubuntu will boot properly and I get to see the login screen. I have no idea what to do to fix that problem. I have to reboot 3 to 5 times everytime I want to get into Ubuntu and I feel like I'm breaking my new Laptop. (its a lenovo ideapad z580 btw. i5 processor and nvidia gtx640 graphics card) I hope someone can help me. Thanks. Edit: i just got a "failed to enable AA error" message when waking it up from suspend. I don't know if that helps or has anything to do with the boot probs.

  • Vertex fog producing black artifacts

    - by Nick
    I originally posted this question on the XNA forums but got no replies, so maybe someone here can help: I am rendering a textured model using the XNA BasicEffect. When I enable fog, the model outline is still visible as many small black dots when it should be "in the fog". Why is this happening? Here's what it looks like for me -- http://tinypic.com/r/fnh440/6 Here is a minimal example showing my problem: (the ship model that this example uses is from the chase camera sample on this site -- http://xbox.create.msdn.com/en-US/education/catalog/sample/chasecamera -- in case anyone wants to try it out ;)) public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; Model model; public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; } protected override void LoadContent() { // Create a new SpriteBatch, which can be used to draw textures. spriteBatch = new SpriteBatch(GraphicsDevice); // TODO: use this.Content to load your game content here model = Content.Load<Model>("ship"); foreach (ModelMesh mesh in model.Meshes) { foreach (BasicEffect be in mesh.Effects) { be.EnableDefaultLighting(); be.FogEnabled = true; be.FogColor = Color.CornflowerBlue.ToVector3(); be.FogStart = 10; be.FogEnd = 30; } } } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); // TODO: Add your drawing code here model.Draw(Matrix.Identity * Matrix.CreateScale(0.01f) * Matrix.CreateRotationY(3 * MathHelper.PiOver4), Matrix.CreateLookAt(new Vector3(0, 0, 30), Vector3.Zero, Vector3.Up), Matrix.CreatePerspectiveFieldOfView(MathHelper.PiOver4, 16f/9f, 1, 100)); base.Draw(gameTime); } }

  • Can't install Ubuntu, black screen after install

    I tried several times, but wasn't able to make it work. I tried all recent types of Ubuntu but it didn't work. Then I tried acpi=off at the beginning of the installation.

  • Ubuntu Server 11.10 boot, white terminal with garbled black text

    - by SpeedCrazy
    I just installed Ubuntu server 11.10 and the install went fine. This system is running on an Intel Pentium II board with onboard graphics. However when I try to boot into Ubuntu I get a white terminal with garbled black text. I have tried various grub 'fixes' as googling the issue seemed to suggest it was a res or grub related issue. I cannot ssh in so the issue does affect Linux as well. I have had no luck with anything thus far and am at my wits end. This was my first Ubuntu excursion as my friend told me it was better for servers than CentOS because it was easier... Not so much.... Does anyone have any ideas as to what the issue could be? When answering bear in mind I am an Ubuntu noob and Linux novice. As of 1/26/12 I have tried to add the console=ttyl line to the /etc/default/grub and run update-grub. This results in the line in the boot parameters that normally reads: linux /vmlunz-3.0.0-12-generic-pae root=/dev/mapper/dev-root rovt.handoff=7 now reads: linux /vmlunz-3.0.0-12-generic-pae root=/dev/mapper/dev-root ro console=ttyl vt.handoff=7 This does not work. Is there anyway to have console=ttyl inserted on a line by itself? I am at my wits ends, Thanks for all your help, Speed

  • Black or White Border/Shadow around PNGs in SDL/OPENGL

    - by Dylan
    having the same issue as this: Why do my sprites have a dark shadow/line/frame surrounding the texture? however, when I do the fix suggested there (changing GL_SRC_ALPHA to GL_ONE) it just replaces the black border with a white border on the images, and messes with my background color and some polygons I'm drawing (not all of them weirdly) by making them much lighter... any ideas? heres some of my relevant code. init: glMatrixMode(GL_PROJECTION); glLoadIdentity(); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glEnable(GL_DEPTH_TEST); glEnable(GL_MULTISAMPLE); glEnable(GL_TEXTURE_2D); glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE); glAlphaFunc(GL_GREATER, 0.01); glEnable(GL_ALPHA_TEST); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glEnable(GL_BLEND); when each texture is loaded: glGenTextures(1, &textureID); glBindTexture(GL_TEXTURE_2D, textureID); gluBuild2DMipmaps(GL_TEXTURE_2D, GL_RGBA, surface->w, surface->h, GL_BGRA, GL_UNSIGNED_BYTE, surface->pixels); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

  • Screen going black, further investigation reveals healthy ram and hard disk, and several kernel oops logs

    - by Virulan
    Six days ago, I went to go take a shower, and I suspended Ubuntu as usual, to save battery life. I came back, and the screen was black. REISUB and general fiddling around did nothing. Restarted, and still had nothing on the screen. Since then, this has happened several times, and the only fix is to 1) force shut laptop, 2) take out battery, 3) hold power button, 4) put battery back in, 5) boot. I have investigated further into the matter, doing a ram test and a hard disk check. Both turned out fine, but then my attention turned towards the error messages I was receiving upon bootup, the whole "System program problem detected" dealio. I did some digging and found four kernel oops logs in my /var/crash. What I can understand of them points to two things, 1) they are connected to my suspending problems, since there are four them (I have had four suspending crashes), and they both confirm that there was a issue with waking up from suspend, and 2) the crashes might have to do with Python (possibly could be jumping to conclusions), since mentions of Python are peppered throughout the logs. At this point, I am unsure of how to continue, and I have come here for help. Is there any way I can fix this? Should I start by uploading the logs here?

  • Black Screen on pressing back button in libgdx

    - by user26384
    In my game when i touch on advertisements and press back button to return on game the i am getting a black screen. I referred this link. I tried to change IosGraphics.java but the change is not reflected in monotouch project. I did the following : Extracted nightly.zip and opened gdx-backend-iosmonotouch-sources From there I changed IosGraphicsjava. I then made a new jar file gdx-backend-iosmonotouch.jar and replaced it with original jar file in the nightly folder. Compressed all the files from nightly folder in .zip file. Used this .zip file to make a new project throuch gdx-setup-ui.jar. I tried to open my project in monotouch and from com-gdx-backendios.dll i found that the changes in IosGraphics are not being reflected. Am I missing something? How do I solve this? I even tried to open gdx-backend-iosmonotouch-sources.jar with winrar and edit IosGraphics.java and save it. Even this didn't work.

I can get to the purple screen on the live cd but then, if I choose "Installing Ubuntu", I have a black screen with a cursor blinking (and nothing else happens). My PC : acer aspire M3920, CPU i5-2300, 8 Gb RAM, NVIDIA gt 405. What I already tried : I tried with 12.04 and 13.04 daily build I tried with a live usb and with a live dvd I tried the following boot options : nomodset, acpi=off I googled a lot and it seems that it could be a graphic card problem. Do you know any other boot options that I could try ? UPDATE This is not a duplicate : I've tried all the common boot options (nomodeset, noacpi...) and it doesn't change anything. With the option "no splash" (instead of "quiet splash"), I can see what happens before the forever-blinking cursor : [sdg] no caching mode present [sdg] assuming drive cache : write trough ata8.00: excetion Emask 0x52 ... frozen ata8 : SError : { RecovData RecovComm UnrecovData...} ata8.00 : failed command : IDENTIFY PACKET DEVICE ... ata8.00 : status : { DRDY } ata8 : hard resetting link Does somebody know what it means ? N.B. astonishingly, Puppy Linux boots fine (but Debian, Fedora and Ubuntu do not) Solution In fact, it was not a graphic card problem. I had to disconnect the dvd drive and connect it to another free sata connector (I don't really understand why Ubuntu had trouble with this connector and Windows 7 not). After that, everything worked fine.

  • Why do my pyramids fade black and then back to colour again

    - by geminiCoder
    I have the following vertecies and norms GLfloat verts[36] = { -0.5, 0, 0.5, 0, 0, -0.5, 0.5, 0, 0.5, 0, 0, -0.5, 0.5, 0, 0.5, 0, 1, 0, -0.5, 0, 0.5, 0, 0, -0.5, 0, 1, 0, 0.5, 0, 0.5, -0.5, 0, 0.5, 0, 1, 0 }; GLfloat norms[36] = { 0, -1, 0, 0, -1, 0, 0, -1, 0, -1, 0.25, 0.5, -1, 0.25, 0.5, -1, 0.25, 0.5, 1, 0.25, -0.5, 1, 0.25, -0.5, 1, 0.25, -0.5, 0, -0.5, -1, 0, -0.5, -1, 0, -0.5, -1 }; I am writing my fists Open GL game, But I need to know for sure if my Normals are correct as the colours aren't rendering correctly. my Pyramids are coloured then fade to black every half rotation then back again. My app so far is based on the boiler plate code provided by apple. heres my modified setUp Method [EAGLContext setCurrentContext:self.context]; [self loadShaders]; self.effect = [[GLKBaseEffect alloc] init]; self.effect.light0.enabled = GL_TRUE; self.effect.light0.diffuseColor = GLKVector4Make(1.0f, 0.4f, 0.4f, 1.0f); glEnable(GL_DEPTH_TEST); glGenVertexArraysOES(1, &_vertexArray); //create vertex array glBindVertexArrayOES(_vertexArray); glGenBuffers(1, &_vertexBuffer); glBindBuffer(GL_ARRAY_BUFFER, _vertexBuffer); glBufferData(GL_ARRAY_BUFFER, sizeof(verts) + sizeof(norms), NULL, GL_STATIC_DRAW); //create vertex buffer big enough for both verts and norms and pass NULL as data.. uint8_t *ptr = (uint8_t *)glMapBufferOES(GL_ARRAY_BUFFER, GL_WRITE_ONLY_OES); //map buffer to pass data to it memcpy(ptr, verts, sizeof(verts)); //copy verts memcpy(ptr+sizeof(verts), norms, sizeof(norms)); //copy norms to position after verts glUnmapBufferOES(GL_ARRAY_BUFFER); glEnableVertexAttribArray(GLKVertexAttribPosition); glVertexAttribPointer(GLKVertexAttribPosition, 3, GL_FLOAT, GL_FALSE, 0, BUFFER_OFFSET(0)); //tell GL where verts are in buffer glEnableVertexAttribArray(GLKVertexAttribNormal); glVertexAttribPointer(GLKVertexAttribNormal, 3, GL_FLOAT, GL_FALSE, 0, BUFFER_OFFSET(sizeof(verts))); //tell GL where norms are in buffer glBindVertexArrayOES(0); And the update method. - (void)update { float aspect = fabsf(self.view.bounds.size.width / self.view.bounds.size.height); GLKMatrix4 projectionMatrix = GLKMatrix4MakePerspective(GLKMathDegreesToRadians(65.0f), aspect, 0.1f, 100.0f); self.effect.transform.projectionMatrix = projectionMatrix; GLKMatrix4 baseModelViewMatrix = GLKMatrix4MakeTranslation(0.0f, 0.0f, -4.0f); baseModelViewMatrix = GLKMatrix4Rotate(baseModelViewMatrix, _rotation, 0.0f, 1.0f, 0.0f); // Compute the model view matrix for the object rendered with GLKit GLKMatrix4 modelViewMatrix = GLKMatrix4MakeTranslation(0.0f, 0.0f, -1.5f); modelViewMatrix = GLKMatrix4Rotate(modelViewMatrix, _rotation, 1.0f, 1.0f, 1.0f); modelViewMatrix = GLKMatrix4Multiply(baseModelViewMatrix, modelViewMatrix); self.effect.transform.modelviewMatrix = modelViewMatrix; // Compute the model view matrix for the object rendered with ES2 modelViewMatrix = GLKMatrix4MakeTranslation(0.0f, 0.0f, 1.5f); modelViewMatrix = GLKMatrix4Rotate(modelViewMatrix, _rotation, 1.0f, 1.0f, 1.0f); modelViewMatrix = GLKMatrix4Multiply(baseModelViewMatrix, modelViewMatrix); _normalMatrix = GLKMatrix3InvertAndTranspose(GLKMatrix4GetMatrix3(modelViewMatrix), NULL); _modelViewProjectionMatrix = GLKMatrix4Multiply(projectionMatrix, modelViewMatrix); _rotation += self.timeSinceLastUpdate * 0.5f; } But providing I understand this correct one pyramid is using the GLKit base effect shaders and the other the shaders which are included in the project. So for both of them to have the same error, I thought it would be the Norms?

  • Ubutu 14.04 triple screen, third screen black and X cursor

    - by Horse
    I am having some issues getting my third screen working properly. I had triple screens working fine on 12.04, using 2 nvidia cards. Did a fresh install of 14.04 and having no end of problems getting it working. It either will just be disabled, or the screen is black with the cursor as an X. I can only enable it from the nvidia server settings tool. The Ubuntu native display settings won't even show the 3rd screen. I tried copying the xorg.conf from my old install, which upon restarting X worked fine on the login screen, but then it just sat there after I logged in and didn’t do anything (mouse was still working). I am using gnome-session-fallback instead of unity if that makes any difference. Still having these issues if I try unity though. How do I get my 3rd screen working and displaying a desktop?

  • OBJ model loaded in LWJGL has a black area with no texture

    - by gambiting
    I have a problem with loading an .obj file in LWJGL and its textures. The object is a tree(it's a paid model from TurboSquid, so I can't post it here,but here's the link if you want to see how it should look like): http://www.turbosquid.com/FullPreview/Index.cfm/ID/701294 I wrote a custom OBJ loader using the LWJGL tutorial from their wiki. It looks like this: public class OBJLoader { public static Model loadModel(File f) throws FileNotFoundException, IOException { BufferedReader reader = new BufferedReader(new FileReader(f)); Model m = new Model(); String line; Texture currentTexture = null; while((line=reader.readLine()) != null) { if(line.startsWith("v ")) { float x = Float.valueOf(line.split(" ")[1]); float y = Float.valueOf(line.split(" ")[2]); float z = Float.valueOf(line.split(" ")[3]); m.verticies.add(new Vector3f(x,y,z)); }else if(line.startsWith("vn ")) { float x = Float.valueOf(line.split(" ")[1]); float y = Float.valueOf(line.split(" ")[2]); float z = Float.valueOf(line.split(" ")[3]); m.normals.add(new Vector3f(x,y,z)); }else if(line.startsWith("vt ")) { float x = Float.valueOf(line.split(" ")[1]); float y = Float.valueOf(line.split(" ")[2]); m.texVerticies.add(new Vector2f(x,y)); }else if(line.startsWith("f ")) { Vector3f vertexIndicies = new Vector3f(Float.valueOf(line.split(" ")[1].split("/")[0]), Float.valueOf(line.split(" ")[2].split("/")[0]), Float.valueOf(line.split(" ")[3].split("/")[0])); Vector3f textureIndicies = new Vector3f(Float.valueOf(line.split(" ")[1].split("/")[1]), Float.valueOf(line.split(" ")[2].split("/")[1]), Float.valueOf(line.split(" ")[3].split("/")[1])); Vector3f normalIndicies = new Vector3f(Float.valueOf(line.split(" ")[1].split("/")[2]), Float.valueOf(line.split(" ")[2].split("/")[2]), Float.valueOf(line.split(" ")[3].split("/")[2])); m.faces.add(new Face(vertexIndicies,textureIndicies,normalIndicies,currentTexture.getTextureID())); }else if(line.startsWith("g ")) { if(line.length()>2) { String name = line.split(" ")[1]; currentTexture = TextureLoader.getTexture("PNG", ResourceLoader.getResourceAsStream("res/" + name + ".png")); System.out.println(currentTexture.getTextureID()); } } } reader.close(); System.out.println(m.verticies.size() + " verticies"); System.out.println(m.normals.size() + " normals"); System.out.println(m.texVerticies.size() + " texture coordinates"); System.out.println(m.faces.size() + " faces"); return m; } } Then I create a display list for my model using this code: objectDisplayList = GL11.glGenLists(1); GL11.glNewList(objectDisplayList, GL11.GL_COMPILE); Model m = null; try { m = OBJLoader.loadModel(new File("res/untitled4.obj")); } catch (Exception e1) { e1.printStackTrace(); } int currentTexture=0; for(Face face: m.faces) { if(face.texture!=currentTexture) { currentTexture = face.texture; GL11.glBindTexture(GL11.GL_TEXTURE_2D, currentTexture); } GL11.glColor3f(1f, 1f, 1f); GL11.glBegin(GL11.GL_TRIANGLES); Vector3f n1 = m.normals.get((int) face.normal.x - 1); GL11.glNormal3f(n1.x, n1.y, n1.z); Vector2f t1 = m.texVerticies.get((int) face.textures.x -1); GL11.glTexCoord2f(t1.x, t1.y); Vector3f v1 = m.verticies.get((int) face.vertex.x - 1); GL11.glVertex3f(v1.x, v1.y, v1.z); Vector3f n2 = m.normals.get((int) face.normal.y - 1); GL11.glNormal3f(n2.x, n2.y, n2.z); Vector2f t2 = m.texVerticies.get((int) face.textures.y -1); GL11.glTexCoord2f(t2.x, t2.y); Vector3f v2 = m.verticies.get((int) face.vertex.y - 1); GL11.glVertex3f(v2.x, v2.y, v2.z); Vector3f n3 = m.normals.get((int) face.normal.z - 1); GL11.glNormal3f(n3.x, n3.y, n3.z); Vector2f t3 = m.texVerticies.get((int) face.textures.z -1); GL11.glTexCoord2f(t3.x, t3.y); Vector3f v3 = m.verticies.get((int) face.vertex.z - 1); GL11.glVertex3f(v3.x, v3.y, v3.z); GL11.glEnd(); } GL11.glEndList(); The currentTexture is an int - it contains the ID of the currently used texture. So my model looks absolutely fine without textures: (sorry I cannot post hyperlinks since I am a new user) i.imgur.com/VtoK0.png But look what happens if I enable GL_TEXTURE_2D: i.imgur.com/z8Kli.png i.imgur.com/5e9nn.png i.imgur.com/FAHM9.png As you can see an entire side of the tree appears to be missing - and it's not transparent, since it's not in the colour of the background - it's rendered black. It's not a problem with the model - if I load it using Kanji's OBJ loader it works fine(but the thing is,that I need to write my own OBJ loader) i.imgur.com/YDATo.png this is my OpenGL init section: //init display try { Display.setDisplayMode(new DisplayMode(Support.SCREEN_WIDTH, Support.SCREEN_HEIGHT)); Display.create(); Display.setVSyncEnabled(true); } catch (LWJGLException e) { e.printStackTrace(); System.exit(0); } GL11.glLoadIdentity(); GL11.glEnable(GL11.GL_TEXTURE_2D); GL11.glClearColor(1.0f, 0.0f, 0.0f, 1.0f); GL11.glShadeModel(GL11.GL_SMOOTH); GL11.glEnable(GL11.GL_DEPTH_TEST); GL11.glDepthFunc(GL11.GL_LESS); GL11.glDepthMask(true); GL11.glEnable(GL11.GL_NORMALIZE); GL11.glMatrixMode(GL11.GL_PROJECTION); GLU.gluPerspective (90.0f,800f/600f, 1f, 500.0f); GL11.glMatrixMode(GL11.GL_MODELVIEW); GL11.glEnable(GL11.GL_CULL_FACE); GL11.glCullFace(GL11.GL_BACK); //enable lighting GL11.glEnable(GL11.GL_LIGHTING); ByteBuffer temp = ByteBuffer.allocateDirect(16); temp.order(ByteOrder.nativeOrder()); GL11.glMaterial(GL11.GL_FRONT, GL11.GL_DIFFUSE, (FloatBuffer)temp.asFloatBuffer().put(lightDiffuse).flip()); GL11.glMaterialf(GL11.GL_FRONT, GL11.GL_SHININESS,(int)material_shinyness); GL11.glLight(GL11.GL_LIGHT2, GL11.GL_DIFFUSE, (FloatBuffer)temp.asFloatBuffer().put(lightDiffuse2).flip()); // Setup The Diffuse Light GL11.glLight(GL11.GL_LIGHT2, GL11.GL_POSITION,(FloatBuffer)temp.asFloatBuffer().put(lightPosition2).flip()); GL11.glLight(GL11.GL_LIGHT2, GL11.GL_AMBIENT,(FloatBuffer)temp.asFloatBuffer().put(lightAmbient).flip()); GL11.glLight(GL11.GL_LIGHT2, GL11.GL_SPECULAR,(FloatBuffer)temp.asFloatBuffer().put(lightDiffuse2).flip()); GL11.glLightf(GL11.GL_LIGHT2, GL11.GL_CONSTANT_ATTENUATION, 0.1f); GL11.glLightf(GL11.GL_LIGHT2, GL11.GL_LINEAR_ATTENUATION, 0.0f); GL11.glLightf(GL11.GL_LIGHT2, GL11.GL_QUADRATIC_ATTENUATION, 0.0f); GL11.glEnable(GL11.GL_LIGHT2); Could somebody please help me?

  • Dim (NEARLY blank) laptop screen, secondary screen works - why?

    - by LIttle Ancient Forest Kami
    My laptop screen is (almost) black while my secondary screen is fine. I believe it to be backlight / brightness related. Problem description it starts when I start the laptop system loads and works fine, just screen has problems I can see the screen though very faintly / dimly - it's hard to see anything which ain't very white e.g. starting screen has big Thinkpad logo in white, large font - I can see it, though very dimly second screen works very well Official backligtht debugging: using acpi setting as prescribed there for Thinkpads didn't help I can see an entry in /sys/class/backlight/ and it changes when I press hotkeys for brightness (current backlight power for instance goes up or down) acpi-off didn't helpm neither did acpi_backlight=vendor Hardware data Laptop is Thinkpad Edge with glossy screen. 4 processors, 2 cores, exemplary CPU data from cat /proc/cpuinfo reports Genuine Intel i5 (M 480 @ 2.67GHz). OS is Ubuntu Lucid, 10.04 LTS, 64-bit, with Linux generic kernel (2.6.32-44) and GNOME 2.32.2 (though I doubt there lies the problem). $ lspci | grep VGA 01:00.0 VGA compatible controller: ATI Technologies Inc M92 [Mobility Radeon HD 4500 Series] $ lshw -C display *-display description: VGA compatible controller product: M92 [Mobility Radeon HD 4500 Series] vendor: ATI Technologies Inc physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 32 bits clock: 33MHz capabilities: pm pciexpress msi bus_master cap_list rom configuration: driver=radeon latency=0 resources: irq:33 memory:c0000000-dfffffff(prefetchable) ioport:2000(size=256) memory:f0300000-f030ffff memory:f0320000-f033ffff(prefetchable) Driver I was NOT running any proprietary drivers, just checked with "Hardware drivers". There is one for ATI that is suggested there, though I didn't need it so far. UPDATE: changing the driver to proprietary one (ATI/AMD FGLRX) didn't help. Tried and failed Resetting / running on power or battery / charging / getting rid of static electricity / warming up *doesn't help* This is NOT a blank-screen problem, at least it isn't following official Ubuntu black-screen diagnostics - I can see my screen, though barely. What I will try next: - check last updates I've made - IIRC I am running on nomodeset already, but will verify this Any ideas how to proceed best? What is most probable cause?

  • Is there a PROPRIETARY driver (NVIDIA or ATI) that actually works with 12.10?

    - by DS13
    NOTE: I see many similar topics on this, but I've tried all their suggestions, and nothing has worked. THE MAIN DIFFERENCE SEEMS TO BE: I always get a black screen with a blinking cursor, while others seem to get through the boot-up and see distorted graphics or just their wallpaper. ISSUE: I do a clean install of Ubuntu 12.10. Boots fine with the “nouveau” graphics driver – graphics (even just menus) are very slow, choppy, and distorted. The three other driver options in Ubuntu (official NVIDIA drivers), all result in a variation of the black screen on boot up. There will be NO access to a command line/GUI in anyway what-so-ever (tried every option recommended out there, but the system is unusable at this stage). I can only reinstall, and try different drivers…and I only ever get one shot at it. QUESTIONS: -Does anyone know of a PROPRIETARY driver that will actually work on 12.10 with a NVIDIA or ATI card? -Should I just buy a newer graphics card to put in as a replacement? MORE INFO: This is my second computer, and I’m just trying to get a working install of Ubuntu on it. I don’t want to put much money into it, as I have seen Ubuntu run great on much older/less capable machines. I’ve got a decent'ish Core2Duo Intel processor (2.13Ghz), 2GB of RAM, 320GB hard drive, 32-bit architecture, and there is no other O/S installed. It appears as if the graphics card (NVIDIA Geforce 7350 LE) is holding me back. TRIED SO FAR: -all drivers available in Ubuntu *all fail -manual install of some different NVIDIA drivers *all fail -also tried installing the generic kernel, Nvidia driver doesn't work in 12.10 *no difference -tried installing 12.04 *same results -every method suggested to at least get a command line after switching to a NVIDIA driver *all fail -UPDATE- Re-tried everything above with a new NVIDIA Geforce 210...same results for everything. -UPDATE #2- Re-tried everything above with a new AMD Radeon HD 6450...installed the proprietary driver from Ubuntu's "Software Sources" menu...EVERYTHING NOW WORKS. See "answer" below for summary.

  • T60 Screen/LCD gets black after some minutes with a highpitched sound rising and fading

    - by Edward De Leau
    Just now my T60 screen got "black" (so no display). On my second monitor: no problems so the vga output works. symptom: Screen blanks / no display but works on second monitor steps to reproduce: - boot - wait (it does not matter what you do you do not have to login or anything) - (now the monitor of the laptop slowly begins to make a ssssssssHHHHHHHHHHHHHHHHHWOEOEssssssss noice of about 10 seconds) - right after the sounds ends the monitor gets black times seem to be the same each time. software: installed no new software before/after, running zone alarm and antivirus. other: it does not feel hot in any place, there dont seem to be running processes with strange behaviour. warranty: out of warranty what was i doing: typing text on a website and doing some php coding in a text editor. Anyone any idea what I can do here other than buy a new laptop? / does it sound familiar to known cases? update: * exactly the same problem: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-Screen-Blackout/m-p/288772 and the second poster (garyj) here: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/Black-Screen-on-T60/m-p/235053#M48627 and here: "i have that same problem. i replaced the CCRL on mine and it works fine when the screen is not screwed in. once the frame of the LCD screen (metal portion) touches the metal on the laptop which holds the screen the screen goes black. If the metal is touching the screen when you boot up it boots up with it being very dimmly lit. " from http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-screen-problems/m-p/205047#M44995 (it seems replacing the lcd is no use, he tried it 3 times). same problem: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-black-screen/m-p/80604#M25914 Hmmm... not handy 3 or 4 months ago I ordered and installed a new fan. Now the LCD. Which does not seem the core isse but some electric issue so it seems replacing the LCD is not the thing todo here. I have the following question: If it is not the LCD that needs to be replaced (see other threads) which parts can I order to fix this? Has anyone got any information which could lead me to identify the issue? I have read replacing the "inverter" AND the "backlightning" would that make sense?
