[oe] X/Xorg can not run successfully

[daniel tian]

Hello, all:
        I already built the openembedded code with "bitbake
e-image-core". but after the rootfs and kernel runs on mips24k board,
I can login with root in minicom.
        But after I run the 'X', the LCD screen becomes black.
        Here is the command I run, and the message shows on minicom:
        root at db1200:~# X

        By the way, the Poky can run on my board normally.

        Does your guys also encounter with this problem?
        Any suggestion is appreciated.
        Thanks very much.
