I use Ubuntu 14.04 and Sage 6.8. If i remember correctly I used a binary to install it. I indeed tried to upgrade my OS, but i went into some troubles doing it (not enough remaining space on my disk).
The strange thing is that i asked my colleagues to try with various OS and Sage version (even 7.4). They all obtained the same problem, render_3d_solid showing nothing. Is JMOL provided by Sage, or is a separate package? Perhaps a recent version of JMOL has problems?
