when i add some LOG in EventHub.cpp,I found that:when open
acquire_partial_wake_lock ,it return permission denied
I/power ( 679): *** set_screen_state 1
I/power ( 679): go_to_sleep now=44106449000 g_error=Permission
denied
so I changed the mod in init.rc
chmod 0666 /sys/android_power/acquire_partial_wake_lock
this time it can be open but the ts has no response now ,it has top
bar slide before the mod being changed
and my new logcat is attached,here are some of it
