Solved: Gemini PIT does not work in Ubuntu Linux (recent versions)

Some people noticed that the Gemini PIT (phase I tool) does not work well with some of the most recent versions of Ubuntu linux. What happens: you try to run PIT, but is welcomed by a blank window.

I found out that this problem happens because PIT is not compatible with the resource Compiz available in the most recent versions of linux. The goal of compiz is to make your desktop prettier, looking more like a Mac OS X. The solution is to temporarily disable compiz while you have to submit your observation proposal using PIT.

To temporarily disable compiz, there are two ways that occur to me:

1. In Gnome: System -> preferences -> appearance -> visual effects, set none.

2. Use the program Compiz-switch, which is what I did.

The same trick also works for the Observing Tool (Gemini OT) program.
