Question

我正在尝试在Red Hat Linux OS上执行使用OpenGL（需要4.x）的c ++代码。它抛出以下错误。

X Error of failed request:  GLXBadFBConfig

硬件信息：操作系统：Linux POWER LE RHEL 7

通过VNC Viewer访问屏幕。

以下是lspci输出：

 lspci | grep VGA
0002:02:00.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 41)

lspci | grep 3D
0004:04:00.0 3D controller: NVIDIA Corporation GV100GL [Tesla V100 SXM2] (rev a1)
0035:03:00.0 3D controller: NVIDIA Corporation GV100GL [Tesla V100 SXM2] (rev a1)

我认为我的机器opengl的版本与程序的所需版本不匹配。所以我检查了glxinfo，下面是输出

此处显示的是1.4版。并且OpenGL供应商字符串不是Nvidia。直接渲染是没有的。似乎它正在使用cpu进行渲染。

如何使我的nvidia驱动程序用于gl渲染？如果使用nvidia驱动程序，那么我的OpenGL版本会增加吗？

我的Nvidia驱动程序不用于OpenGL渲染吗？
