如何为 i915 驱动程序启用直接渲染？

我的glxgears工作还好，不过有点慢。在一些 python OpenGL 上运行时演示，它崩溃了

X Error of failed request:  BadRequest (invalid request code or no such operation)
  Major opcode of failed request:  155 (GLX)
  Minor opcode of failed request:  168 ()
  Serial number of failed request:  114
  Current serial number in output stream:  114

我的 OpenGL 版本和台面如下，

$ glxinfo | grep "OpenGL version"
OpenGL version string: 1.4 (2.1 Mesa 10.1.3)

此外，直接渲染设置为 false。我想验证是否是“直接渲染”导致了问题。但我在网上没有找到合适的解决方案。有人能帮我吗？
