Hello I can`t execute simple OpenGL and GLUT Apps on my Pentium 150 MHz, with Chips and Technologie Gfxcard and Linux SuSE 7.2 I know, the speed of the Notebook is very low to run GL progs clean, but I only bought the Computer to test my own written opengl codes in my Holydays , not to play with them... speed doesn`t matter. I thought that OpenGL can run in Softwaremode with a lot of graphic cards, even cards without 3D support, is that right ?? I don`t know why my Glut Initialization Code ends with only a black screen, and not with some vertices etc. as I wrote it. The same with some SDL Video Mode, there comes a error message like : Setup video mode failure. The options for X and the Window resolution should be right, I think. 800x600 and 16bit. Need some feedback.. thanks Do I need to buy a Notebook with 3D Card ? (too expensive)
