Hello! After boot-up, but before log-in, comes a warning window with the following message: Xsession: warning XRDB command not found: X resources not merged.
At first, I was getting a small square window with a large lightbulb. It said: Xsession and needed to be "OK'd". Then and now everything seems to start normally, but I'm worried. What is the meaning of this warning? my x-windows is xfce4
