Default Linux on TF300TG

Hi all.
I want to ask a few questions on installation xubuntu on a tablet.
Read the topic in the development forum and encountered a problem.
I put rutfs.img in internal memory (data/media/0/linux), flashed the kernel, but when I load xubuntu tablet is not included, and reboots and goes into the android, wi-fi does not work. What is wrong?
I have a TF300TG with chromix JB 5.4 with stock moded kernel, i flashed kernel rabbit 2.2.9 and used a xubuntu 13.04.

P.S. In development forum I can not write because few reports
