    Hydrogen, rosegarden and dead Jack

    HI all,
    Having some real weird troubles here.
    I have never been able to get rosegarden running on this pc.
    Seems to be a low level Jack problem. I have read ooddles of posts tried many things over the months but generally give up. Can some one please help me.

    hydrogen start up from terminal but gives a jack memory error

    cannot lock down memory for jackd (Cannot allocate memory)
    loading driver ..
    apparent rate = 44100
    creating alsa driver ... hw:0|hw:0|1024|2|44100|0|0|nomon|swmeter|-|32bit

    ok I had to add

    Code:
    sudo gedit /etc/security/limits.d/audio.conf
    
    and added these two lines
    @audio - rtprio 95
    @audio - memlock unlimited
    now rosegarden works and plays midi.

    hydrogen still wont start jack server tho

    I'm not much of an expert with this stuff, but have you installed the ubuntu studio controls? I was having the same kinds of problems with hydrogen before I installed all the extra ubuntu studio packages from the software center.
