    This segfault occurs in unity-editor-2018.1.2f1 when -nographics is not provided on the cmd line and there is no X display running on the machine for the user. Notice that main() is calling InitializeX11() and calling into libX11, which shouldn't occur when -batchmode is provided as a parameter.

    $ unity-editor -quit -batchmode -projectPath . -buildLinux64Player ./out
    No protocol specified
    Segmentation fault


    $ cat /home/user/.config/unity3d/Editor.log

    Error opening default X display

    Yes, the Unity editor on Linux currently requires a usable X display, even in batch mode.
