>#10 0xb5090d89 in QMessageLogger::fatal(char const*, ...) const () from /usr/lib/i386-linux-gnu/sse2/libQt5Core.so.5 This is printing a message. Can you run plasmashell from a command line and tell me what it says?
Hello sorry for delay if I do under shell as user : # X& # export DISPLAY=0;0 # xclock& # plasmashell & plasma starts without problems and is usable. It is only with startx that plasmashell aborts (in loop since it seems startx wants to restart it each time). I don't really know how to start plasmashell by hand in this environnment. No message is displayed on X screen except the crash window.
