System Information
Operating system:

Ubuntu 20.04 x64 with NVIDIA Card 960m
Ubuntu 16.04 x64 with intel grafics.

However, i run blender from snap, so libs should be the same on both installs

Graphics card:

Blender Version
Blender 2.91.2 (hash 5be9ef4177 built 2021-01-19 16:16:34) as delivered via snap install

Short description of error
Blender crashes when trying to render an eevee scene from the command line
when either DISPLAY is not set or when trying to launch via an remote X11 connection (ssh -C -X).

Exact steps for others to reproduce the error

This run is with DISPLAY set (ssh -C -X):

This is a side effect of the same problem described in #84675 (Batch Rendering Crashes if EEVEE set in scene),
The difference is that there, the GPU is not supported.
And here the GPU cannot create a context without a display.

I don't know if it's possible to create an OpenGL context without a display (@Jeroen-Bakker or @fclem can give you more information on that).
If it is not possible, I would say that it is a duplicate of the other report.

IMHO rendering EEVEE should also be possible on the command line. If there is no display to connect to then blender should revert back to non-GPU rendering....

Maybe see https://community.khronos.org/t/opengl-rendering-without-display/58289 for hints.

Hmm. Had a closer look at #84675. That one talks about Windows, mine talks about Linux, which is quite a large difference regarding display handling IMHO.....

So should this one be re-opened since it is not a duplicate?
