I built my own custom made kernel image with Morty Yocto project. I fetched meta-freescale, meta-fsl-arm-extra, meta-toradex-nxp, meta-toradex-bsp-common and other necessary layers, to build the xfce image.
The HDMI is working and the monitor is showing the console message. mxcfb1, mxcfb2 are enabled in device tree (correspond with the /dev/fb0, /dev/fb1). I have no idea why the xfce doesn’t work. Any help is appreciated.

Vivante module is there:
root@colibri-imx6:~# dmesg | grep drm
[ 1.191646] [drm] Initialized drm 1.1.0 20060810
[ 1.198757] [drm] Initialized vivante 1.0.0 20120216 on minor 0
root@colibri-imx6:~#
But there is no such /usr/lib/xorg/modules/extensions/libglx.so file and /usr/lib/xorg/modules/drivers/vivante_drv.so. .
I have added
xf86-video-imxfb-vivante \
xserver-xorg-extension-viv-autohdmi \
xserver-xorg-extension-glx \
into my image.bb, did the trick.
