13 Yes, thanks.I already run realtime-lsm. However that package doesn't
14 provide any performance improvements to the system. What it does is
15 allow a user to do things he'd normally need ot be root to do, such as
16 requestion realtime processing performance within Jack. As root you
17 can always do this. As a user you never can until
18
19 1) realtime-lsm is installed
20 2) There is a group created that is given lsm rights
21 3) The user is added to that group.

25 mark@lightning ~ $ cat /etc/modules.autoload.d/kernel-2.6
26 <SNIP>
27 fglrx
28 snd-intel8x0
29 snd-hdsp
30 ohci1394
31 sbp2
32 realtime gid=600 any=1
33 mark@lightning ~ $

35 mark@lightning ~ $ cat /etc/group
