I've tried this with an internal Intel video card: it showed the window, but it there were some artifacts and the window was unable to do anything (close/maximize/resize) and showed Segmentation Fault when window is closed with Alt+F4. I've clearly removed all ati fglrx drivers, made a reboot. and it fails with Segmentation Fault again:

So, if I'll follow the logic with ATI drivers, I need an Intel drivers, but they are pre-installed with Ubuntu 8.10

...
>>> from OpenGL import GLUT
>>> GLUT.glutInitDisplayMode(GLUT.GLUT_RGBA | GLUT.GLUT_DOUBLE)

Program received signal SIGSEGV, Segmentation fault.
