我有一个可视化工作站，我通过 SSH 连接到它（应该启用 iGLX，因为我可以glxgears通过 SSH 运行），它附带了 Titan X 卡和 Matrox 适配器，我相信它是集成 Intel Iris VGA 的适配器。我使用存储库包（而不是使用运行文件）安装了最新的 CUDA。我成功编译并运行了（一些）正确执行的 CUDA 示例程序。
我遇到的问题是，在我看来，GL 应用程序不是使用 nVidia 卡上的 OpenGL 运行，而是通过集成卡运行（甚至可能使用 MESA CPU 模拟的 OpenGL）。
glxinfo| grep -i opengl

我还检查了它libGL.so似乎是由 MESA 安装的，而不是由 nVidia 安装的：
