I am using LinuxMint11 Gnome desktop variant. I like GDM combined with openbox. I am running into a problem though, Java apps (in this case Minecraft) will not run properly. F11 begins to open a fullscreen client, then it reverts to original size (whichever size I had it before F11). I have searched everywhere I could find for an explanation or help. I have found that people where having trouble with Java apps & openbox. As well I found a youtube video showing a fix for ArchLinux, I don't know how to convert their tutorial for LMX/Ubuntu. (I believe this tutorial is addressing my problem, I may be wrong.) http://www.youtube.com/watch?v=zigIZIW04Ko. Thanks for you're time!
