Ah, sorry probably is me not you.
I edit as you requested but there is not /tmp/strace.log file, this is the 
commands I used:

bogdan at zmeu:~$ sudo systemctl daemon-reload     
bogdan at zmeu:~$ sudo systemctl start rtkit-daemon
Job for rtkit-daemon.service failed because the control process exited with 
error code.
See "systemctl status rtkit-daemon.service" and "journalctl -xe" for details.
bogdan at zmeu:~$ systemctl status rtkit-daemon.service

   Loaded: loaded (/etc/systemd/system/rtkit-daemon.service; disabled; vendor 
preset: enabled)

What "Loaded: loaded (/etc/systemd/system/rtkit-daemon.service; disabled; 
vendor preset: enabled)" *disabled means in the log?
