"Could not start dbus. Can you call qdbus?"
by deretsigernu from LinuxQuestions.org on (#5QXE2)
I can't log in to my regular user with KDE. I can log in as root. After I enter my password and the log in continues, a small windows opens and says "Could not start D-bus. Can you call qdbus?" I'm using 14.2 64bit.
I'm not sure what exactly I changed when I last logged in a couple of days ago. I did install Miniconda the last time I logged in. I had no issues with KDE at that point.
I searched for some possible solutions. One asked what's in /usr/bin/startkde:
