Before 2002, it was not working at all on Linux. At the end of 2006, I was still using simulated software fullscreen mode. The Metacity (GNOME) bug was annoying... About 2 or 3 years ago, real FSEM worked on Linux but its implementation did not respect the NET VM specification, it is still the case now. I did not notice this problem until KDE became less permissive in its fourth version.

I'm an active user and an occasional contributer, that is why I have to ask the authorization to the JogAmp foundation in order to use a few lines of its source code in AWT both in Oracle Java and in OpenJDK. Maybe there is a problem of license :(
