I am just getting back to ubuntu Linux after many years.
A fellow amateur operator KB1OIQ has a ubuntu 11.10 (previous remix-12) distribution for HAM operators
here at sourceforge if you want to virtualize it to verify.
I like that it uses simpler icewm window manager due to size and speed of HP 1125 Netbook
I have been able to add other CAD and graphics applications but can't get brlcad-mged working in menu
I compiles it from source for practice by following instructions
I modified /etc/externals for including /usr/brlcad/dev-7.22.0/bin/ and so mged works from terminal
I copied BRL-CAD/brlcad-7.22.0/misc/debian/brlcad-mged.png to /usr/share/icons/
Finally from sudo /etc/X11/icewm/programs I added following line to make menu choice available
prog "BRL CAD" /usr/share/icons/brlcad-mged.png mged
Icon with menu choice shows so syntax and executable are correct
Are any options needed ?
