Thank you, but I allready have autologin and it does not solve the problem as 
the lock occurs when I put the computer to "suspend".

I may have found another solution by using rtcwake and hibernate:

rtcwake -m disk -u -t <timestamp>

It's a little more complicated, as you first have to generate the 
correct "number" for the date and time, but the computer then hibernates and 
when waking up seems to do a regular boot and does not lock the screen.

Shutting it down seems to work, but I had to use rc.local to run the shutdown 
command at boot and as root, so i must not forget to remove this after use...

The current method - still being tested - is:

- edit /etc/rc.local for shutdown
- program Kaffeine for recording
- generate the date/time number
- run rtcwake with this number

The computer then hibernates and (hopefuly) comes back to life at the right 
time, records and then shuts down.
