Hello, I also have a problem with opengl. I am using Kubuntu latest version. I use the 3D drawing program "IntelliPlus architectural pro" emulated with wine under linux. The software works well but I can not display the OpenGL rendering. The 3D view with hidden line or 256 colors is possible, but when I ask OpenGL rendering, I get: 1) or with a black screen 2) an office block with stripes made of the application. My hardware: Intel Core 2 Quad Q9400 CPU 2.66Hz 3.2GB of RAM ATI 5700 series Radheon I enabled the graphics accelerator kubuntu. What to do? Thank you for helping me Ailan J'utilse Google translate - I'm sorry
