Dear All,
I'm running Suse 9.3 on a reasonable machine. (1.6GHz AMD athlon, 512MB
ram). My studio at the moment consists of Rosegarden, Hydrogen,
zynaddsubfx, qsynth and Ardour(when I don't get CPU overflows).
I've been using KDE, and upon reccomendation I tried FVWM as it's
lighter, but I had the same number (lots!) of xruns and problems. It did
run slightly better; I had 9 extra megs of ram free but realistically I
want no xruns. I'm not running a patched kernel as I'm unable to find
out what patches SUSE needs to run that conflict with the realtime
patches. My kernel is 2.6.11 atm. Any advice? Apologies as this is
really trivial; it's just that I have very little idea what to do about
it.

id upgrade to a kernel that is less ancient. and try something like fluxbox or wmii. the
former at least has a panel with a system tray. which is most of what Gnome or KDE offers
for the desktop at significantly less cost. if you still want to load up a GUI file
manager now and then nothing is stopping you from installing Thunar...
xruns could be due to your preemption settings (in kernel .config) or video drivers. but
trimming the fat off your desktop can't hurt.

Disagree, using Fluxbox over Gnome is not likely to make a difference
with a recent kernel.

Lee, do you think that the same can be said about KDE rather than Gnome?

worries ;)

You seem to suggest SuSE needs a special kernel patch... You just
build a kernel from kernel.org and apply ingo's patches found at
http://people.redhat.com/mingo/realtime-preempt/
Lots of confusing options but you can always ask for help here.

You don't even have to apply Ingo's patches.

But stripping down your workplace to focus on music exclusivly can
enhance your musical productivity.
On the other hand a round of patience every now and then can do the
same thing...
I am running a full KDE will making music (10ms latency with an
sblive), unless I want to use two screens without quiting kde, then I
run a second xserver with fluxbox. :-)
So long,

Your choice of Window Manager should not make that much difference. Using a
much more recent kernel and recompiling it to allow realtime capabilities
should do the trick. You shouldn't be getting xruns on a machine like this
unless you really push it.

I did so also for some Months and had the same issues - it´s the
kernel, comrad ;-). I strongly recommend to install NovellSuse 10.1 in
the flavour of jacklab:
http://www.jacklab.net/
If you want to stay with Suse, this is the only easy solution, 9.3 wont
do unless you apply some serious work with unsure outcome.
I switched to Ubuntu Dapper Drake wich comes with a standard-kernel that
is built properly with DESKTO_PREEMPT enabeled with very very good results:

"perfect"):
