Most examples were functional until about 2 months ago. I've stopped working on that machine at that time because of poor OpenGL support of the intel drivers (for instance, they were missing the GL_EXT_framebuffer_object extension). I have now switched to the most recent intel xorg drivers which may be slightly experimental, so maybe this is causing the problem? > And another one ;-), is this the only > example that has this problem or does for example CSM/Simple also > crash at roughly the same place ?

However, it doesn't complain about the 'glXCreateContextAttribsARB' function any more.
