Ubuntu xvfb-run a Unity application with Nvidia leads to a “core dumped”

I build a Linux standalone version of my game. And I want it to run in batch mode in Ubuntu so that I can write some code to get screenshot automatically for further usage.

My env:

• Ubuntu 16.04

• Unity 5.4.3

• Nvidia K2200 graphic card

• Nvidia Drider version: 367.57-0ubuntu0.16.04.1

• xvfb-run

But when I tried to run my game through SSH with this kind of command, I came across a core dumped and everything aborted:

xvfb-run --auto-servernum --server-args='-screen 1 2560x1600x24:32' -e /home/unreal/video/error_xvfb ./test.x86_64 -batchmode -logFile /home/unreal/video/stdout_unity

And in that log file "stduo_unity", some error happened but I have no idea what it is talking about:

 Got a SIGABRT while executing native code. This usually indicates
 a fatal error in the mono runtime or one of the native libraries 
 used by your application.

Then I try to uninstall Nvidia driver and everything works fine. But as it cannot use graphic card, the app is with low efficiency.

Then I re-install driver again, and try building Linux standalone app with from Unity 5.2 to Unity 5.5. Nothing better.

Now I really don't know want should I do. Can someone help me with this? Thanks!
