I have made this little script #!/bin/sh /usr/sbin/915resolution 38 1280 768 24 in /etc/init.d and made it executable; how do I use update-rc.d to create the symlink to the correct init directory? My script needs to run before X is started... I have looked at the man pages 'init' and 'update-rc.d', but I don't know where to start.
