This is the messages printed in messages window of qjackctl: 15:41:20.664 Patchbay activated. 15:41:20.667 Statistics reset. 15:41:20.738 ALSA connection graph change. 15:41:20.929 ALSA active patchbay scan... 15:41:20.932 ALSA connection change. 15:41:21.136 ALSA active patchbay scan... 15:41:35.807 Startup script... 15:41:35.809 artsshell -q terminate sh: artsshell: not found 15:41:36.230 Startup script terminated with exit status=32512. 15:41:36.232 JACK is starting... 15:41:36.234 /usr/bin/jackd -R -p128 -dalsa -dhw:0 -r48000 -p256 -n4 15:41:36.244 JACK was started with PID=3261. no message buffer overruns jackd 0.116.1 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. loading driver .. apparent rate = 48000 creating alsa driver ... hw:0|hw:0|256|4|48000|0|0|nomon|swmeter|-|32bit control device hw:0 15:41:37.555 JACK was stopped successfully. 15:41:37.557 Post-shutdown script... 15:41:37.559 killall jackd 15:41:37.561 JACK has crashed. jackd: no process killed 15:41:37.980 Post-shutdown script terminated with exit status=256. 15:41:38.442 Could not connect to JACK server as client. - Overall operation failed. - Unable to connect to server. Please check the messages window for more info. It seems to me that the actual cause is not revealed in these messages, perhaps there is better log somewhere else? > In a (bash) shell, running: > ulimit -l will tell you how much memory you can lock > ulimit -r will tell you at what realtime priority you can run software These will give me right numbers that I have set in limits.conf (250000,99). > On a system like a netbook, you can also try 'jackd --no-mlock' or > 'jackd --unlock'. Unlock will make jack not lock some parts of the > memory (gui toolkits etc.), no-mlock just skips memlock totally. These don't seem to help much. But the thing I'm also interested is why same Jack settings work when running qjackctl as sudo? .j _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
