   Configuration issues
  Hello everyone!I'm facing a problem with my OpenGL sofware. I developed a software using Qt and OpenGL, and it works. I tested it on more than 5 different computers, with Windows XP, XP 64, Vista and Windows 7. It worked fine in all of them.However, I got this notebook recently formatted and I was trying to configure it for using my software. I installed the Visual C++ Redistributable and put all the DLLs necessary in the same folder as the executable. Even so, the OpenGL contexts in my Qt interface continues to show a white image. I tried a earlier version of my program, without Qt, and it showed me the same white image. It should display the image captured from a webcam. I'm using textures, but I don't see how it can be a code problem, once it worked in a lot of different computers.I tried a different OpenGL application, not related to mine, in this notebook and it worked, so I guess it's not an OpenGL problem exclusively.Do you guys have any idea of what I may have forgot? I'm out of clues here.Thank you!UPDATE: I forgot to tell you that the notebook is installed with Windows Vista Business Edition.

I'm out of clues here.There are dozens of potential issues, so help us narrow it down a bit: what graphics card (vendor and model) does the notebook have, and what OpenGL version is your application using (i.e. the result of glGetString(GL_VERSION))?I would also recommend that you run your program with GLIntercept, and see if it shows any OpenGL errors.Among likely possibilities, if this notebook uses an older/integrated GPU, it might be missing support for non-power-of-2 textures, or if OpenGL drivers are missing, it might be falling back to Microsoft's software OpenGL implementation.   ;  Thanks for your reply, swiftcoder.The graphics card is NVIDIA GeForce Go 7400 and it shows up in the device manager like this:NVIDIA GeForce Go 7400 (Microsoft Corporation - WDDM)What does this microsoft thing mean? I googled about WDDM, but I didn't understand it well. Does it mean that I'm using some generic Windows driver?The OpenGL version that I'm using is 2.1.2.I'll try the GLIntercept software and put the results here later.Thanks!   ;  Sorry, I forgot to come back here to tell. The problem was indeed the graphics card drivers. I downloaded the NVIDIA official drivers and it worked. I didn't even use the GLIntercept.Thanks all!
