When I call glutFullScreen on my app in Ubuntu 9.04 with both the stock version (2.4.0), 2.6.0 RC1, and SVN Top of Tree I get two interesting behaviors.
1. The window resizes, but all the window decorations are still present (on windows it goes into game mode it appears).
2. When coming out of fullscreen (with the use of glutPositionWindow and glutReshapeWindow), it causes a rehshape event...
