I run PD as root (not sudo, but real root) for click-free operation. But Ubuntu has this weird thing where you can't be root, you can only sudo. Very strange... anyways, worth a try.
I also use fluxbox with very little else going on in the GUI. Spent almost a year tuning Linux to get really optimum performance for live gigs and recording situations, really the idea is that less is more. Ubuntu/Red Hat/SuSE etc just have too many processes (especially graphical ones that cause interruptions) running at once, IMHO. best, D. patrick wrote: > hi, > > i don't use pd-extended, but i think it's almost the same. the only > option missing is: -nosleep (useful for dual-core). > > so be sure in qjackctl - setup: > Realtime > Periods/Buffer: 2 > Sample Rate: 44100 (or more) > Frames/Period: 256 (i am running at 64 without glitches) > > then for pd: > pd -rt -jack -r 44100 -nosleep -audiobuf 256 -channels 16 -alsamidi > -mididev 1 etc... > > and finally, be sure to edit /etc/security/limits.conf: > @audio - rtprio 99 > @audio - memlock unlimited > @audio - nice -20 > > and of course, add yourself to audio group (reboot to be sure). let us know. > > ah yes, a long time ago i was using icewm, because gnome was causing > glitches in pd. but now it seems ok here. > > pat > > > Atte André Jensen wrote: >> Hi >> >> I get clicks and "DIO errors" at random intervals under linux/ubuntu >> with jack (no xruns).
