I'm trying to get synergys to launch on startup.  From the command line I use:

usr/bin/synergys --daemon --no-tray --debug NOTE --name Gremlin --crypto-pass xxxx --config ~/.quicksynergy/synergy.conf --address :24800

which works fine from the command line, but if I put into the "greeter-setup-script=" at /etc/lightdm/lightdm.conf, as per https://help.ubuntu.com/community/SynergyHowto#Autostart_Synergy_before_logging_in_.28LightDM.29
then when I boot up, the mouse isn't shared, and synergys is not in the process list (ps, pgrep)

greeter-setup-script=/usr/bin/synergys --daemon --no-tray --debug NOTE --name Gremlin --crypto-pass xxxx --config ~/.quicksynergy/synergy.conf --address :24800


Whats the proper way to get synergys to launch on login?
