Is there a workaround to run a lightdm script? The one in the docs doesn't work. Anything placed there will prevent X from working.

The script I would like to use is my KVM utility synergy. I thought for a while it was synergy that was causing the problems. However, I found that anytime there is a lightdm.conf file with anything on that line X will fail to load.

Example:

greeter-setup-script=/etc/lightdm/test.sh

The text.sh file is simply a shell command to indicate it ran:

test.sh:

#!/bin/bash

date >> /tmp/test.log

Thanks in advance for anyone who has any input, or as I mentioned a workaround so that I could have a resource that will run upon X startup before the user actually logs in.
