![损坏的 OpenGL:glxinfo 和 inxi 中的错误 GLX 渲染器(Nvidia 而不是 Intel)](https://linux22.com/image/867018/%E6%8D%9F%E5%9D%8F%E7%9A%84%20OpenGL%EF%BC%9Aglxinfo%20%E5%92%8C%20inxi%20%E4%B8%AD%E7%9A%84%E9%94%99%E8%AF%AF%20GLX%20%E6%B8%B2%E6%9F%93%E5%99%A8%EF%BC%88Nvidia%20%E8%80%8C%E4%B8%8D%E6%98%AF%20Intel%EF%BC%89.png)
我花了一整天时间试图解决这个问题,我希望这个友好论坛中的某个人可以提供帮助:
我正在运行以下设置:
Distribution: Ubuntu 14.04.01
Kernel: 3.13.0-43-generic
Hardware: Intel Core i7-3840QM CPU with integrated Intel HD Graphics IvyBridge GPU
当我运行 glxinfo 时,我得到:

事实上,此安装从未安装过 Nvidia 显卡/驱动程序。所以不知道为什么我在这里有 nVidia 引用。以下是一些可能有帮助的信息:

OpenGL 使用间接渲染,将数据发送回您的本地系统以便在本地进行呈现,并且它会检测并列出该硬件而不是您服务器上的硬件。
我也有同样的困惑,但服务器中有一块 Nvidia 卡,检测到的是 AMD 卡。以下是来自 glxinfo 的相关部分:
$ glxinfo | egrep 'direct|client|server|OpenGL'
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
server glx vendor string: SGI
server glx version string: 1.4
server glx extensions:
client glx vendor string: NVIDIA Corporation
client glx version string: 1.4
client glx extensions:
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: AMD Radeon HD 6770M OpenGL Engine
OpenGL version string: 1.4 (2.1 ATI-1.24.38)
OpenGL extensions:
我的系统中根本没有 AMD 硬件,所以我也很困惑,直到我意识到我的本地系统拥有 Radeon HD 6770M。当 glxinfo 报告客户端和服务器时,它看起来就像 X 一样定义它们;服务器是运行 $DISPLAY 中指向的 X 服务器的主机,而客户端是运行 glxinfo 的主机。因此,即使如您所说,服务器计算机上没有 X 服务器,但仍有一个正在运行并通过网络被 glxinfo 查询的服务器。我猜您的本地系统上确实有运行 X 的 Nvidia 硬件。
作为一个实验,您可以尝试在未指定显示的情况下运行 glxinfo,您会发现它甚至无法工作:
$ DISPLAY="" glxinfo
Error: unable to open display
如果您在远程服务器上运行 X 服务器,将其配置为使用直接渲染,并使用 VNC 之类的工具与 X 交互,则可以在服务器上使用硬件加速。在这种情况下,它只会将完成的图像发送到您的本地系统。
