*Opensuse Leap 15.2 / Phyton 3.6 / KDE-Desktop*
Dear maintainers,
Installation of the latest pytrainer version 2.0.2 successful.
Running pytrainer comes up with the error listed below.
*echo $DISPLAY shows :0*
What causes this and how can I fix this problem?
Thank you and have a nice day!
Best regards,
Peter
