Thanks. It seems that problem is solved on one way. When I switch to DLite, Kindle doesn't accept input anymore. However Dlite still does. Fortunately I solved this by changing 14th line of stopdk.sh from
Code:
dstop=$(killall -STOP KindleApp)
to
Code:
dstop=$(killall -9 KindleApp)
Now it shuts down DuokanLite when I switch back to the Kindle.
There is another thing:
I installed both Duokan and DuoakanLite and try to use launchpad way described on
this thread on this installed Duokan. Unfortunately it doesn't work correctly especially when I try to switch back to Kindle(It continually reboots). Could you solve this,too?
