The FAE of ASPEED Co. had checked this issue. They found the "modesetting" (drm) driver loaded and the xorg-server running will cause segmentation fault which is logged in Xorg.0.log. But they have no idea for this segmentation fault. They provide me a xorg.conf file and I put xorg.conf file into /etc/X11 and reboot and then I can see the X-window running properly.
