  Hi Goran!

 I've never used set_rlimits myself so please excuse me if I'll give you
 wrong advices.

 Probably the best way to run jackdbus with realtime privileges will
 be to edit this file:

 /usr/share/dbus-1/services/org.jackaudio.service

 It contains the commandline that D-Bus session daemon uses to start
 jackdbus when it is needed.

 I'm not sure how set_rlimits is used but if I got it right, you have to
 start jackdbus through it.     Starting jackd(bus) through set_rlimits is just one
step. I wanted to
know how to pass realtime option (it's -R for jackd if I remember
correctly) when jackdbus accepts "auto" as the only argument (config file
or something?)

...
  Do you start other audio apps through set_rlimits? If
so you may want
 to run ladishd through set_rlimits as well. Its dbus service file is:

 /usr/share/dbus-1/services/org.ladish.service

 All apps are started by ladishd. gladish is just a GUI that talks to
 ladishd. Or you can specify set_rlimits in the commandlines for apps but
 I think this will be quite wrong approach in general.     Setting ladishd through
set_rlimits would be the way to go, I think.

...
  Other possibility is to start the D-Bus session daemon
through
 set_rlimits but how to do it depends on how tge session daemon is
 started on your machine.     No, that would be wrong. One would want only some
apps/daemons with
rlimits.

...
  Please, tell me whether these advices are helpful. I
think it will be
 useful if the ladish.org wiki has a page that describes how to properly
 setup computers for using set_rlimits. Also you are more than welcome to
 join the ladish mailing list and/or join the IRC channel where people
 using ladish share thoughs about ladish functionality and the problems
 they have.     I think this is helpful, but I can not test it at work. I have
rehearsals and some work to finish, so I hope I'll get back to you with the
info this week. Thanx anyway!
