Where do I configure syndaemon default parameters?

By default it is called with -i 2.0 -K -R -t . I have a script that re-runs it with parameters that I need, but how do I do this properly?

I am on ubuntu 12.04


Dash -> Startup Applications

  • Add
  • Give it a name and put the command in for the script you need:

Reason for this ... there is not config file and those settings are hard coded.

  • Yes, that's what I do, just running the script from .bash_profile. I was hoping that there is any way to configure it. Thanks anyway – misza222 Mar 20 '13 at 21:39
  • nope sorry. someone believes it is best to hard code something like that :) – Rinzwind Mar 20 '13 at 21:41

    If I do this, two syndaemon processes end up getting started. – midopa Dec 12 '17 at 8:04
  • Thank you for this answer ! I tried and failed with other solutions to this problem, this one solves it :D – Olivier Bégassat Jan 10 '19 at 20:09

As Rinzwind already pointed out, these settings are hardcoded in unity-settings-daemon:


As a workaround, rename syndaemon to syndaemon.orig

mv /usr/bin/syndaemon /usr/bin/syndaemon.orig

and create a script syndaemon that just calls the original binary with the correct parameters:

cat << EOF > /usr/bin/syndaemon
/usr/bin/syndaemon.orig -K -R -i0.5

Make it executable with

chmod +x /usr/bin/syndaemon

    This is kind of wonky, but it works and ensures only one syndaemon process is started at launch. – midopa Dec 12 '17 at 8:05

For those using Xubuntu:


I've found that making it half a second delay works well for me. The command you need to run at auto start is

syndaemon -i .5 -K -t -R -d
