[Gllug] "X connection to :0.0 broken"

[Qingning Huo]

Hi,

I am wondering what does this error message mean, and what cause it.

X connection to :0.0 broken (explicit kill or server shutdown).

Say I just run xclock from a terminal window and close it by clicking
the "X" button.  Sometime it quits normally, and at other times it
generates the above text, and then $? will be 1 instead of 0.

Is it normal or does it indicate some kind of error?  Why does it
happen kind of randomly?
