--- Comment #8 from David Faure <fa...@kde.org> --- :#3 QMessageLogger::fatal (this=this@entry=0x7ffe86010420, msg=msg@entry=0x7f24a7f28b78 "QXcbConnection: Could not connect to display %s") at global/qlogging.cpp:784 :#4 0x00007f24a7e94c40 in QXcbConnection::QXcbConnection (this=0x5573eb5194a0, nativeInterface=0x5573eb50fc90, canGrabServer=<optimized out>, defaultVisualId=4294967295, displayName=0x0) This says that you don't have the variable $DISPLAY set. Just to be sure -- is this on X11? You have X running, right? I have no idea why your setup doesn't set $DISPLAY, but that's definitely a setup bug. -- You are receiving this mail because: You are watching all bug changes.
