export LIBGL_ALWAYS_SOFTWARE=1

/home/ubuntu/carla-0.7/CarlaUE4.sh /Game/Maps/Town01 -windowed -ResX=400 -ResY=300 -carla-server -carla-world-port=9988

on a machine with no GPUs, I see a segfault when initializing the Unreal Engine.

Or is it impossible to run Unreal without a GPU?

Full output below.
