conky, suspend and service.unit

I was able to solve the error from here: https://forums.bunsenlabs.org/viewtopic … 13#p144313
with the help of the German man page for 'systemd.service'. Then it was due to the special start conditions of sh scripts. This means that several start commands can be specified with the service-Type=  ‘oneshot’

Please note that shell command lines are not directly supported. If shell command lines are to be used,
they must be explicitly passed to a type of shell implementation. Example:

           ExecStart=sh -c ‘dmesg | tac’

the service

    [Unit]
    Description=unklar:after-suspend.service: Start at suspend
    DefaultDependencies=no
    After=suspend.target

    [Service]
    Type=oneshot
    Environment=DISPLAY=:0
    ExecStart=sh -c /usr/local/bin/journal-entry started from after-suspend.service "active/running"
    ExecStart=sh -c /home/unklar/John/john.sh

    [Install]
    RequiredBy=suspend.target

which shows this flawless output after suspend:

systemctl status after-suspend.service

Unfortunately, the Conky's are still not displayed.

I suspect now,
-a rights problem
-the ‘service’ ends too quickly

Anyway, I'm going to take a break for 4 days...
