Edit sources.list

Add the relevant line to your /etc/apt/sources.list file


deb  squeeze main

Ubuntu Precise

deb  precise main

Ubuntu Natty

deb  natty main


apt-get update
apt-get install ola ola-python


Since ola-0.8.23, you can choose to start olad at boot. The question is asked the first time you install ola. If you chose 'No', you can change it with:

sudo dpkg-reconfigure ola

Since you choose 'Yes', the init script will be active and you will get the advantages below. Take care, if you start olad manually in a terminal, you will loose these advantages.

  • Control the olad process with:
sudo /etc/init.d/ola start
sudo /etc/init.d/ola stop
sudo /etc/init.d/ola restart

  • olad is started by the 'olad' system user (automatically created and added to groups dialout and plugdev).

So olad is ready to use USB devices (thanks to udev rules).

  • conf files are in /var/lib/ola/conf/ and owned by 'olad'.

To configure the plugins, you need to add yourself to the olad group. For example:

sudo adduser renzo olad

then logout and login again (you need to do it only once).

You are now able to open the conf files, for example: gedit /var/lib/ola/conf/ola-artnet.conf

  • You can try my bash script to set the plugins easily

(but uncomment the second line to use debian path):

  • Read the olad logs with:
cat /var/log/syslog

if you want to see the 20 last lines:

cat /var/log/syslog | tail -n20
