Comment 3 for bug 469114

Having a hook sounds like an excellent idea for user scripts. One simple and usable approach I've seen is to check for the existence of a callback file and if so, execute it. So for example if ~/.disperCallback exists and is executable, run it. Then you could also ship some common scripts (such as switching gnome-panel to the largest screen like below, or the wallpaper one which can take a few arguments) somewhere like /usr/share/disper/scripts, and then all you have to do to enable them is throw each one you want in ~/.disperCallback.

Also, thanks for this great project, it is very excellent and works perfectly for my simple needs! I have a question but I'll ask it on LP Answers :)
