Hi,
We are new to Paraview but our team has some experience working with other softwares like 3D Slicer, Pyvista, etc.
I wanted to try Paraview which looks like an easy to use and very helpful tool for our visualization purpose of medical data.
I am using linux centos(3.10.0-1160.11.1.el7.x86\_64) and Paraview v5.9 for linux.
When I downloaded and opened Paraview it gave me this Warning(attached in 2nd screenshot).
Then we ran this command before starting Paraview, and this time there was no error. Worked I guess.
```auto
export MESA_GL_VERSION_OVERRIDE=4.6
```
Then I tried loading my Dicom dataset from local machine as given in this documentation: [2. Loading Data — ParaView Documentation 5.8.1 documentation](https://docs.paraview.org/en/latest/UsersGuide/dataIngestion.html)
The data we believe was successfully loaded as we could see the some metadata about the dicom data in the “Information” tab on the left, like the range of pixel values, dimensions of each axes, etc, which were accurate.
But them when we tried to load the 3D view of the data selecting “Volumes” and clicking the “eye” icon next to the loaded directory. We got this error:
```auto
ERROR: In /builds/gitlab-kitware-sciviz-ci/build/superbuild/paraview/src/VTK/Rendering/VolumeOpenGL2/vtkVolumeTexture.cxx, line 932

vtkTextureObject (0x1bb24380): Failed to determine texture parameters. IF=0 F=6403 T=5126
```
We wanted to understand what’s wrong here, why the data is not able to load into a 3D view.
Any help or suggestions would be highly appreciated. We are also attaching out GPU information in the 1st screenshot.
Thanks,
Pranay

Your GPU driver seems complety out of date or incorrect. what is the output of `glxinfo` ?

I am from Pranay’s team. Apologies for the late update. You are right about GPU driver being out of date. Independent of this, we found that we were missing libOpenGL.so in our installation. After bringing in NVIDIA provided libOpenGL.so for the same driver, we can run ParaView in client/server rendering mode with EGL version running on GPU and client using Mesa on CPU.
IIUC, this is the only mode available for running on GPUs plugged in headless servers? We get following for “glxinfo | grep -i opengl”: -
```auto

OpenGL vendor string: VMware, Inc.
OpenGL renderer string: llvmpipe (LLVM 7.0, 256 bits)

Thanks Mathieu for your super-prompt response!
