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.
