Hi  all

first of all thanks to chaos for the answer of my previous post... it 
was a really dumb question...:P

Now my actual problem:

i've upgraded my fc1 ccrma partition to fc2 not without problems, but 
now everything appears to work fine for me (fc2 not ccrma), except that 
i cannot run qjackctl as a normal user. My upgrade process consist on 
uninstalling all extra packages  (ccrma and others), then upgrade to fc2 
via yum, and finally getting ccrma fc2 packages and updates.

first: it gets me into an error telling me that he could not open ALSA 
sequencer as client and so there's no midi patchbay available.
    20:51:59.149 Patchbay deactivated.
    20:51:59.596 Statistics reset.
    20:51:59.601 Could not open ALSA sequencer as a client. MIDI 
patchbay will be not available.
    ALSA lib seq_hw.c:446:(snd_seq_hw_open) open /dev/snd/seq failed: 
Acces denied

second: when i try starting  jackd using alsa driver (oss and dummy 
aparently workingbut without midi patchbay) i get this:

That's it.. some aditional info:
