Anyway, I'd say that the problem is that you have installed: * openjdk-6-jre * openjdk-7-jre-headless, but not openjdk-7-jre (can you confirm? If you install openjdk-7-jre, does the bug get solved?) Geogebra ensures (via its dependencies) that there is at least one complete (i.e., non headless) JRE installed, but then uses the most recent one, even if that one is headless. Then GeoGebra dies, because it requires a working GUI. I don't know whether there is a general solution to this problem (i.e., detecting which installed JREs are non headless and using one of them). Maybe the Java team has something to comment? (I had a look at java-wrappers, but there seems to be no provision for this kind of problems) Thanks.
