Usually this is because Tk send is not working.

The problem is that there is a missing directory that needs to be created.
If you're using operating in runlevel five you can look at your
/var/log/xdm-error.log file and you will notice that the first line should
look like this:
xdm error (pid 491): Cannot open server authorization file
/usr/X11R6/lib/X11/xd
m/authdir/A:0-a00491
The directory that needs to be created is /usr/X11R6/lib/X11/xdm/authdir.
After this is created, xauth takes over and everything is fine.
