yes.  FC3, 2.6.10-2.1.ll.rhfc3.ccrma.

oh, ok.  i didn't want to try those yet since they were "unstable" and
this one seems to be working decently.  i have 0.4 and 0.5 installed,
>   /etc/rc.d/init.d/rtload status

I would do this, but I have started getting the "GDM is not able to
write to your authorization file", so I can't log in as a user
normally anymore.  I did the ctrl+alt+F1 thing, though, logged in as
user, and did it, and it says:

Realtime kernel module is loaded, current parameters are:
 any=1; gid=-1; mlock=1

But I don't know if that is a valid way to do it.  Now I have to
figure out how to log in normally.  *sigh*  I had to do
ctrl+alt+backspace because it locked up, and now I can't login.  i
tried deleting files, so it's not a full hard drive.

Oh, ok.

Ok.  I should have said this was qjackctl, and it's just doing
whatever it was doing by default.  I will change it when I get back
into user mode.
