:

EITHER – from a base install of ubuntu studio <http://www.ubuntustudio.org/>(
7.04) (which has all the low latency and realtime stuff by default, and also
contains loads of other good audio/visual software)


   - install the initial packages needed :

sudo apt-get install build-essential scons libsndfile1-dev
libasound2-dev subversion libjack0.100.0-dev libxt-dev fftw3



OR – from a base install of ubuntu <http://www.ubuntu.com/> feisty (7.04)


   - install the initial packages needed :

sudo apt-get install build-essential scons libsndfile1-dev
libasound2-dev jackd libjack0.100.0-0 libjack0.100.0-dev qjackctl
subversion fftw3



   - (optional but highly recommended) install the package
   linux-lowlatency and add real-time capabilities to the audio group (will
   require a reboot)

sudo apt-get install linux-lowlatency
sudo su -c 'echo @audio - rtprio 99 >> /etc/security/limits.conf'
sudo su -c 'echo @audio - memlock 250000 >> /etc/security/limits.conf'
sudo su -c 'echo @audio - nice -10 >> /etc/security/limits.conf'




BOTH INSTALLS, CONTINUE HERE –


   - check out and install supercollider from subversion (don't bother
   installing from ubuntu packages at all)

svn co https://supercollider.svn.sourceforge.net/svnroot/supercollider/trunk
 supercollider
cd supercollider
scons PREFIX=/usr X11=yes SCEL=no LID=yes

sudo scons install



   - install sced from http://artfwo.googlepages.com/sced by following
   the instructions (it really is FAR better than using emacs) :)
   - run qjackctl (which shows up in your sound & video menu, click
   setup, and choose realtime. then boot jack up. you should get no errors...
   - setup a nice directory for supercollider to use as a working folder

cd
mkdir scwork
cd scwork
mkdir synthdefs



   - run gedit, enable the sced plugin, configure the plugin to your
   scwork folder, then click tools -> supercollider mode, and off you go!
   (hint: control-E is evaluate and escape is abort)
   - if you get an error about primitive filePut not allowed,
   re-configure sced, as it has usually forgotten that you chose scwork instead
   of your home dir, then try again.
   - Note: " the interpreter expects the "synthdef"-folder in /home/$USER
   but i placed it somewhere else"

based on a mail by
Matt<http://www.nabble.com/ubuntu-feisty-and-supercollider-tf3617888.html#a10102013>
:

I believe it's not necesary to install realtime-lsm, because Ubuntu has
pam_rlimits for assigning resource limits to users. I've never used
realtime-lsm with ubuntu.

After updating from Edgy to Feisty, I installed the linux-lowlatency
metapackage, and then ran the 3 commands above (I think my old limits.conf
was overwritten on upgrade) and rebooted. After that I got no complaints
about realtime from either Jack or Supercollider. My pre-fiesty-upgrade
build of supercollider worked just as before.

Hope that saves some people a bit of time,


this is it;
