Desktop environment is running, and no, I have not forgotten that. I've even changed it to a non-default script.

If your desktop environment is already running, you don't need a custom script to start it.
I suggest you to have a look at the chrome launcher thread again. Several users posted working example scripts there.
Also, i think this is not the right place here. As mentioned in the first post, Chrome Launcher related stuff should be discussed in it's own thread.
