Hello,
I have a workstation for scientific calculations based on RHEL 6.6.
The workstation is equipped with a NVIDIA Tesla M2090 GPU that is used for CUDA.
My users need to use use graphics applications that use OpenGL, like paraView, on remote PCs via TurboVNC and VirtualGL, but an error is thrown when they are launched, about GLX extension missing.
Actually, when I try glxinfo from my remote TurboVNC client (display :6), I obtain the following
$ glxinfo
name of display: :6.0
Xlib: extension "GLX" missing on display ":6.0".
Xlib: extension "GLX" missing on display ":6.0".
Xlib: extension "GLX" missing on display ":6.0".
Xlib: extension "GLX" missing on display ":6.0".
Xlib: extension "GLX" missing on display ":6.0".
Error: couldn't find RGB GLX visual or fbconfig
Xlib: extension "GLX" missing on display ":6.0".
Xlib: extension "GLX" missing on display ":6.0".
Xlib: extension "GLX" missing on display ":6.0".
Xlib: extension "GLX" missing on display ":6.0".
Xlib: extension "GLX" missing on display ":6.0".
Xlib: extension "GLX" missing on display ":6.0".
I can’t figure out how to fix the problem.
Does anyone have a clue?
I installed the NVIDIA drivers following the “NVIDIA CUDA Getting Started Guide for Linux” at http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/ using the runfile installation.
As part of the installation, I had to remove the Nouveau drivers following the instructions on paragraph 4.3.2:
Create a file at /etc/modprobe.d/blacklist-nouveau.conf with the following contents:
blacklist nouveau
options nouveau modeset=0
Regenerate the kernel initramfs:
$ sudo dracut --force
After that, the drivers seem to work correctly:
$ nvidia-smi

I noticed that the Tesla M2090 is used as a 3D controller and not as VGA controller, but I can’t say if this matters and how:
