You probably need to set -Dsun.java2d.noddraw=true on the java command line to
get around some conflicts with the AWT use of the hardware.
Following this message is some test code for full screen exclusive mode. It
works on a Dell/Windows 2000 machine with Radeon ATI drivers when we use
-Dsun.java2d.noddraw=true. If the property is not set then Alt-Tab doesn't
seem to work on some systems.
There does seem to be an order dependency. See the comment below about
device.setFullScreenWindow(). Apparently you have to set full screen mode
before adding any other components to it.
