I plan to build an image for P1020.
I am using SDK 1.5, Ubuntu 13.04.
I have setup the host enviroment.
As succeeding to complete command of host-prepare.sh, and if rebooting computer, I cannot enter x-window forever,
I am sure passwd is right, and if not rebooting computer, I can compile kernel, module, everything is ok.
I reinstall Ubuntu 13.04 and repeat above-mentioned procedure, nothing change.
It looks like that SDK1.5 package updating damage some system file of ubuntu 13.04
