OK, last night I did a test install of FC5 as an upgrade to my
FC3+planet installation.
If I log in as root, Jack is in realtime mode, and can't overload my
system enough to cause even one xrun.  But when I am logged in as a
normal user, Jack doesn't run in realtime mode, and I get xruns even
on playback.

Is this caused by something PAM related?  (Forgive me, I am a relative newbie)
