So keep that in mind +when reading these guides. + +Missing GUI +----------- + +As it turns out Java has a problem with rendering the GUI correctly on +non-reparenting window managers, such as *DWM* -- the one I use. The solution +to the problem is easy though. If JDK is patched to check for the environment +variable **_JAVA_AWT_WM_NONREPARENTING**, you can set this to equal *1*. I've +created a startup script for GeoGebra like so: + + _JAVA_AWT_WM_NONREPARENTING=1 .geogebra-portable + +This workaround is of course not only applicable to GeoGebra, but to all +Java-applications with similar problems. + +Using GTK theming in GeoGebra +----------------------------- + +If you want to have the same look and feel in GeoGebra, as the rest of your GTK +applications, this can be easily achieved by setting Java options through the +environment variable **_JAVA_OPTIONS**, like so: + + _JAVA_OPTIONS='-Dawt.useSystemAAFontSettings=on -Dswing.aatext=true + +' + +Again, this is of course applicable to all GUI applications in Java.
