@hfpop: That's... interesting. Is the KA1-LE using an IR-grid or a capacitive touchlayer?
We have a specific workaround in place for the neonode grid found on the H2O, because mine was being very finicky...
If the issue is similar (except, in my case, touch *never* woke up), this one may also need a little 'nudge'...
If it is an IR-grid, can you check through the terminal plugin (or a proper SSH shell) if you can find a path to something resembling
Code:
/sys/devices/virtual/input/input1/neocmd
?
