freenx arrow keys don't work

After reading tons, having no clue, flailing around, on both client and server I did System, Preferences, Keyboard, Layouts, "Evdev-managed keyboard" or similar, and then in the nx session, on the server, I did System, Preference, Keyboard shortcuts, Desktop, Take a screenshot. It was "Print", I pressed "Ctrl+PrtSc", it changed to "Ctrl+Print", and now ALL the nav keys work fine.

ln -s /usr/local/jdk/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/firefox/plugins
