Hi all,

When trying to run my Unreal Project (C++, Blank Template) using Unreal 4.17.2 on Linux Ubuntu 16.04.3 I’m having the error on the method IsRHIDeviceIntel when checking check(GRHIVendorId != 0);.

I already went through the links provided on the related question but nothing helped.

If I run gxlinfo| grep OpenGL i have the following output:

OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 4.0, 256 bits)
OpenGL core profile version string: 3.3 (Core Profile) Mesa 17.0.7
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 17.0.7
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 17.0.7
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00
OpenGL ES profile extensions:

Running glxinfo| grep version I have the following:

server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
    Max core profile version: 3.3
    Max compat profile version: 3.0
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.0
OpenGL core profile version string: 3.3 (Core Profile) Mesa 17.0.7
OpenGL core profile shading language version string: 3.30
OpenGL version string: 3.0 Mesa 17.0.7
OpenGL shading language version string: 1.30
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 17.0.7
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00

I’m using EC2 Instances from AWS (if this info helps).

EDIT - added callstack

The error stack is:

Any of you have an idea about how to solve this?
