You want to make sure you kill the right X server, if more than
one is running on the machine.
perl -e '
($pid, $ppid) = `ps axl -Ouser | grep X | grep \`whoami\` | awk '{ print $2 $3 }'`;
print "$pid\n";
'
That won't work on Solaris, but should work on Linux and FreeBSD.
Making it actually work is an exercise for the reader (you may have to
play with the quoting a bit, and no doubt there's a much better way to
do that in Perl than what I've shown).
