OpenGL VBO无法正常工作

我一直在玩NeHe的OpenGL教程一段时间，直到我决定转向更现代的教程。但是，无论我选择哪个教程，我都无法使用VBO和顶点数组渲染单个三角形。虽然立即呈现效果很好。

以http://ogldev.atspace.co.uk/www/tutorial03/tutorial03.html中的代码为例， make '或将项目复制到代码块进行编译，以便在运行时生成黑屏。
（请注意，本教程明确地将顶点数组的大小而不是字节数传递给glBufferData，但即使修复该错误，结果也保持不变）

我目前正在运行Ubuntu（虽然我在同一台PC上运行Windows时出现此问题），我目前正在使用的编译器是GCC 4.7.2

我还认为我的视频卡（Mobility Radeon 4330）可能会因为不支持VBO而导致此错误，所以这是glxinfo的输出：

您的卡Mobility Radeon 4330的驱动程序目前是支持OpenGL 2.1的Mesa，而现代OpenGL教程需要3.1 + OpenGL支持。

具体来说，虽然http://www.opengl.org/sdk/docs/man2/xhtml/glVertexAttribPointer.xml表示版本2.0+已经足够，但有些驱动程序并不完全支持它。我建议你升级到你的卡的最新驱动程序，这将是OpenGL 3.2，你可以愉快地尝试现代教程中的所有练习，如OGL或Arcsynthesis。
