Ah ok.

Build for crespo device (nexus S) using cm 10.1 and trusty preinstalled
daily from 25/11/2013
(not sure of the date) trying to port flipped so I've installed all in
system.img and put android system.img on /var/lib/lxc/android/system.img
and android-ramdisk on /boot

Ubuntu start can access with adb but have a black screen.

When I run lxc-console -n android -t0 I can do logcat where I can see the
message
linker.c (1095): /system/lib/libubuntu_application_api.so not found

Like I guess that communication betwen android firmeware and ubuntu is
crucial
I try first to correct this. /system/lib/libubuntu_application_api.so is
present and I can stat it
it is regular file.

I've a look on jb, linker.c and try to add some trace but unfortunatly I've
no more informations on logcat and I can't find why.. It's why I need some
help.

I'm not english speaker it's maybe why I have some trouble to explain
exactly what happen .

Regards
