many thanks for your quick reply, in the meantime I had to send back my faulty display and must wait for a replacement. The error messages appear whether Jivelite is running or not. What I also saw was that when I tried to stop Jivelite I got the response „not successful, try kill“ but the application was stopped anyway and the kill option was not even presented. What I also discovered was that for the original Pi 7″ display I need an extra plugin for this touchscreen.
Is the setting of the display in Jivelite itself then disregarded or what do I have to set there ?
