Hmmm..looks like something ate my original.
Bill,
Actually I went ahead and stuck the following line in rc.local
/usr/bin/renice -10 -p `/bin/ps -elf | /bin/grep /etc/X11/X | /bin/awk
'{print $4}' | /usr/bin/head -1`
I haven't rebooted yet to actually test, but I do believe that the X
server is started by the time rc.local is read.
I did go look in the XFree86 FAQ and they do recommend re-nicing the X
server as well.
