>Description:
When running X, these error messages appear at first :

  trap: 'SIGKILL' cannot be caught
  xauth: file /home/<user>/.serverauth.xxx does not exist

I know these messages are not very important, but it seems to me that they are really useless and can lead one to believe that there is a real problem !!!


>How-To-Repeat:
In the text shell console launch X :

$ startx

In X swap to text shell console :

Ctrl-Alt-F1

  trap: 'SIGKILL' cannot be caught
  xauth: file /home/<user>/.serverauth.xxx does not exist
  ...

The messages are also visible when you exit X and go back in the text shell console.
>Fix:
these messages can be avoided with the following changes in the file /usr/X11R7/bin/startx at line 176:

# create a file with auth information for the server. ':0' is a dummy.
    xserverauthfile=$HOME/.serverauth.$$
++  touch $xserverauthfile
--  trap "rm -f '$xserverauthfile'" HUP INT QUIT ILL TRAP KILL BUS TERM
++  trap "rm -f '$xserverauthfile'" HUP INT QUIT ILL TRAP BUS TERM
    xauth -q -f "$xserverauthfile" << EOF
add :$dummy . $mcookie
EOF
