"Initial System Configuration" merely describes the steps that must be performed, outside of the context of VirtualGL, before VirtualGL can be installed. That includes ensuring that the 3D X server is running and supporting hardware-accelerated OpenGL. The VirtualGL User's Guide contains no directions for installing and configuring the 3D X server, because the 3D X server is not part of VirtualGL. As described in the "Terminology" section (https://cdn.rawgit.com/VirtualGL/virtualgl/2.6.3/doc/index.html#hd002001), the 3D X server is an X-windows server that runs on the VirtualGL server machine and is attached to a GPU in the same machine. If you are trying to remotely access a workstation (a machine that can also be used locally, as opposed to a headless server that can only be used remotely), then the 3D X server is the same as the local X server on the workstation. It sounds as if you can successfully log into that local X server when you're sitting in front of the workstation. That means that the 3D X server is working, but it doesn't necessarily mean that it's using the correct drivers. That's why the VGL User's Guide suggests running glxinfo locally on the 3D X server. That will show you what the OpenGL vendor string is, and it should contain "NVIDIA Corporation" if the nVidia proprietary drivers are in use. However, if you know that you've successfully used the 3D X server (the workstation's local X server) with hardware-accelerated OpenGL in the past, then you can consider it to be configured, and you should proceed with "Granting Access to the 3D X server." Also, please note that X11 forwarding has nothing to do with the 3D X server. When you use X11 forwarding, server-side applications send all of their X11, GLX, and OpenGL commands over the network to be rendered on your client machine, so the X server in the server machine is never involved. Thus, that's not a relevant test of anything related to VirtualGL. > I'm not sure if you need anything in particular but just in a case... > > lspci -- 1:00.0 VGA compatible controller: NVIDIA Corporation GM204 > [GeForce GTX 970] (rev a1) > less /proc/info -- Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz > > This will generally be on a local LAN. > > Thanks for any help, > > Jim > -- You received this message because you are subscribed to the Google Groups "VirtualGL User Discussion/Support" group.
