Thankyou for the input.

There was a thought that some of these tweaks would get triggered by jackd starting. I can see that may not work in this case. I also have an app that sits in the tray and with a click and selection can change a set of tweaks for up to four modes of operation or normal and three more. I was thinking normal, audio, video and graphics... that is what icons I have made anyway. I use it on my netbook to set scaling, turn off cron and friends, unload a kernel module that messes things up and turn off pulse->jack bridging. What is still needed is a GUI config app so the user can tune what gets turned off or on for each mode. As Tim Henderson says in his message there is a xfce utility that could help. However, my thought is that there are enough other things a user may need to tweak for audio or video work, that one app that does all at once would be a lot handier. My app, BTW just triggers a runlevel switch for rl 2-5 (runlevels 3 to 5 seem to have fallen to disuse any more) and then uses 4 upstart scripts (init scripts could be used too, but as ubuntu is moving away from that, I chose upstart) to set things on entering and exiting that runlevel. Just a quick note: on any ubuntu system don't try setting the system to "performance" before 60 seconds after login.
