I’m learning OpenGL using this book. I’m trying to run the first example, which is here. It compiles fine, but when I try to run it, I get an X11 BadAlloc error:

X Error of failed request:  BadAlloc (insufficient resources for operation)
Major opcode of failed request:  128 (GLX)
Minor opcode of failed request:  34 ()
Serial number of failed request:  38
Current serial number in output stream:  39

As far as I can tell, this error is caused when glutCreateWindow is called. I don’t know if this is an issue with X itself or with my graphics card, which is a nVidia geForce 310.

    Your graphics drivers don’t support OpenGL version 4.0.

    glutInitContextVersion(4, 0);

    I changed it to 3.3:

    glutInitContextVersion(3, 3);

    and it works fine. You can get your OpenGL version from glxinfo.
