Try something simpler:

Environment=DISPLAY=:0
ExecStart=/usr/bin/python /opt/cyclades/bin/t_idl.pyo

Anyway, it seems that the script either exits (maybe some error?) or
daemonizes itself.  If it's not failing to start with an error, you
probably need to change (starting from the snippet I put above) to
Type=forking, or make the script not exit.
