LXLE linux, automatic logon, unwanted hangs waiting for ENTER key

Hi All, I installed LXLE linux newest legend version (32 bits) on a EEEPC which is aimed as an internet radio. I want to automatically logon and start clementine. This works, except one caveat: logging in without typing the password goes well, but it is still needed to hit the ENTER key, which is annoying. I search the web for 2 days to find the solution, but avail. Can someone give me a solution or the clou as to the right direction I have to search? Until now I tried to find the script that evokes the logon screen. The bootlog file indicates that after calling logon there is a "hold" waiting for the key hit.

Thanks in advance!
