I've had this issue with RTMT (and other java apps) under Linux with compiz enabled.

Under Ubuntu go to System->Preferences->Appearance and set Visual Effects to None.

I can't even get the RTMT to install on Ubuntu. I get a Java error like:

argus@Io:~/Documents$ ./CcmServRtmtPlugin.bin

Preparing to install...

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Do you have the 64bit kernel? Any ideas?? If you can help me install, maybe I can help with the blank message problems hah.

Try turning off Compiz fusion. Go to system->preferences->appearance and on the effects tab select none. Works for me. - Whoops just seen earlier post mentions this -
