Hello everybody!
Hi Alexandros!
I run kubuntu 10.10 with 2.6.35-25-generic kernel and I am very pleased and
enthusiast about it's aesthetic feel.
However, I want to record live my guitar. With this kernel, the latency
that I
get in Jack, (with 512 frames/period, 44100 Sample Rate and 2
Periods/Buffer)
is 23.2 msec which is a little bit annoying. If I lower the Frames to 256 I
get 11.6 but I have many Xruns.
it would be helpful to know what you audio interface is to perhaps help you
get better performance.
Also, in some cases (and yours might be one) if you add the user to the
'audio' group it helps performance as well.
So, I am thinking to install the realtime kernel. The question is: are
Kubuntu
10.10 and real-time kernel full compatible with each other? Do I need to
make
any considerations/modifications in my system before installing the
real-time
kernel. Did anyone had any problems with Kubuntu 10.10 and real-time
kernel?
Good question. But since it's all based on Ubuntu I wouldn't expect much
deviation in performance except in specific, restricted cases.
I searched on the web and I only found some generic comments like "that KDE
isn't suitable for audio production", but with no serious support that
validate those comments.
I think many people would argue with that position.
KDE is not as "light" in terms of memory/CPU-usage as Fluxbox but if one
disabeles the desktop-search-system, KDE will have little impact on the
audio-performance.
Kernel and System-Setup are really important. If a capable basic-system
is set up carefully, the desktop-system does not matter much. Running
KDE instead of Fluxbox will not have much more impact than another Synth
started in a session.
I use to run KDE4.3 under Suse 11.2 with jengelh-RT-kernel on my
quad-core workstation and tested the same system with Fluxbox and LXDE
also. I did not see any improvement of performance so I stuck with KDE
for convenience ;-)

A good friend created and maintains that KXStudio distro which is based on
Ubuntu Studio and uses KDE. It's brilliant and beautiful and includes a
-realtime kernel I believe. It's a live DVD so I would highly recommend
researching it. You can find it here:

I am looking forward to your replies and comments!
Thank you in advance,
Alex
